Several of the bigger players in the industry are Mosaic – producers of such cameras as the Mosaic 51 and Mosaic X camera systems – and Teledyne Flir producers of the range of Ladybug cameras (more about the difference between camera sensors and camera systems below).

Mosaic, founded in 2018 and one of the new players to the game, has already established itself as a major contender, even pushing other producers to make changes to their products after years of limited to conservative innovation.  

Mosaic camera systems have been brought to the forefront of capturing high-resolution imagery, at scale, focusing on offering users an intuitive, all-in-one device for collecting street view imagery and geographical coordinates.

Teledyne Flir, historically, has developed the Ladybug3, Ladybug5, Ladybug5+, and Ladybug6. These cameras have set significant benchmarks in the industry over the last decades, embedding themselves among many standard mobile mapping systems. 

However, Mosaic has not only met these benchmarks but also introduced unique advancements that distinguish themselves from the Ladybug models.

This article takes a look into the intricacies of these differences, providing a detailed comparison backed by technical data and customer feedback. This exploration will offer insights into why Mosaic systems are increasingly becoming the preferred choice for professionals in mobile mapping.

Historical Context and Evolution

The evolution of Mosaic in the mobile mapping industry is a story of consistent innovation, aimed at addressing the limitations of existing technology. Mosaic’s camera systems, including the Mosaic 51 and Mosaic X, are embodiments of this journey, introducing advancements that set new industry standards. These improvements include higher resolution imagery, enhanced durability, and more efficient data processing, reflecting a commitment to quality and user experience.

On the other hand, the Ladybug series has shown its own progression, with the Ladybug3, Ladybug5, Ladybug5+, and Ladybug6. Each iteration brought enhancements, but Mosaic’s development, especially with the Mosaic X, took a different route. Focusing on a more compact design, standalone functionality, and exceptional image quality, the Mosaic X camera system represents a leap in mobile mapping technology.

Technical Comparison: Mosaic vs. Ladybug

The following information is based on a comparison of the technologies as discovered from online publications as well as freely provided feedback from users of the various devices.

Camera Resolution and Image Quality

Mosaic camera systems, particularly the Mosaic 51 and Mosaic X, offer superior resolution compared to the Ladybug series. Mosaic camera systems feature a 12K-13.5K resolution respectively, surpassing the Ladybug5’s 8K resolution.

After years of stagnation regarding the resolution of the LB cameras, the newly released Ladybug6 camera now achieves 12K resolution as well, although as any good photographer will tell you, numbers are not necessarily the end all be all of image quality.

Spatial Accuracy vs Ground Sample Distance (GSD)

Ladybug6 advertises “72 Megapixel images with a spatial accuracy of +/- 2 mm at a 10-meter distance.” 

This term “spatial accuracy” is misleading as it suggests each pixel represents a 2 mm area on the ground, which is not standard industry terminology. 

Instead, in standard terms, the camera’s actual performance under ideal conditions corresponds to a “ground sample distance” (GSD) of 4 mm per pixel. “GSD” refers to the physical area on the ground covered by each pixel in an image, and is the conventional way to describe this aspect in the imaging industry.

Teledyne, the manufacturer, uses the term “spatial accuracy of +/- 2 mm” rather than GSD, seemingly to suggest a higher level of precision.

In contrast, the Mosaic X, offering 13.5K resolution panoramas, effectively uses its pixels and field of view to achieve a superior spatial resolution—approximately 10 percent better than that of the 12K resolution panoramas of the Ladybug 6.

Image Overlap and Pixel Efficiency

Mosaic cameras are designed to use pixels more efficiently, with a smaller overlap between camera views. This design results in higher-quality stitched images.

In contrast, Ladybug cameras tend to have a wider field of view with a bigger overlap, which can lead to inefficient pixel usage and lower overall image quality.

Industry Feedback and Observations

Recent industry feedback about the Ladybug6 camera system has highlighted several concerns and observations:

Mosaic’s Resolution Advantage

The Mosaic X camera systems boast a resolution higher by more than 1000 pixels. This substantial difference in resolution results in sharper, more detailed imagery, positioning Mosaic as the preferred choice for high-precision mapping tasks.

What this means for the user:

Higher resolution, combined with sharper, more detailed imagery means that the end-user of the data is able to see more details, more clearly and zoom in more closely. 

This also means that when running AI/ML algorithms on Mosaic imagery, there is a higher chance of correctly identifying and classifying the desired objects 

Customer Insights and Preferences

As stated earlier in this article, the following feedback has been provided to Mosaic employees over the past year from current Ladybug users. Several customers have expressed a desire to transition away from Ladybug cameras, citing a range of reasons:

Minimal Improvements: Some customers noted that the progression from Ladybug5 to Ladybug6 lacked significant technological advances, which didn’t meet their evolving needs.

Camera Design and Performance: Concerns were raised about the geometric design of the Ladybug cameras, impacting their overall performance. Additionally, the lightweight nature of these cameras sometimes led to practical challenges, such as becoming entangled in tree branches due to its irregularly-shaped design.

The housing of the Ladybug6 camera leaves the lenses exposed and this can mean that when passing under low-hanging foliage, the cameras are prone to getting caught in tree branches.

Customer support and response time: There is more to any piece of hardware and software. There is also customer support, whether on the pre-sales side or after purchase. Mosaic customers have consistently provided positive feedback regarding the quality and speed of support. 

“We’ve been pleased with your quality of product and service, really your level of service stands out amongst our other experiences.”

Mosaic’s Technological Edge

Mosaic’s camera systems offer distinct technological advantages that enhance user experience and data utility:

Open Format Data Manipulation 

Mosaic’s open format allows for more versatile and user-friendly data manipulation. This flexibility is crucial for custom applications and diverse mapping needs.

The camera captures and stores data in 6 video file containers (mp4) which then form a flexible starting point for nearly any post processing need. 

Many Mosaic customers enjoy creating a stitched 360º video so that they can quickly move through their construction sites, road works, or rural utility routes with ease. 

Others choose to stitch and extract geo-referenced panoramas which are then ready to be loaded into most GIS software or map viewers with high geographical accuracy.

However, those wishing to colorize point clouds with the data will find that non-stitched images offer greater results. Check out various Mosaic customers who are colorzing point clouds, using their preferred LiDAR solution and workflow.

Users looking to utilize the data within photogrammetry software for 3D modeling also benefit from having non-stitched images, as stitched panoramas are never an ideal source of imagery for such procedures. 

The Mosaic X offers a significant advantage in terms of data processing. Its use of a nonproprietary file format allows for greater flexibility, as users can employ a variety of software tools for stitching and photogrammetry without additional costs.

The Ladybug6 utilizes a proprietary format, requiring a specific license for data processing. This can add extra costs and limitations in terms of software compatibility. Additionally, post-processing is necessary for color and exposure correction, as the initial output tends to be flat with inadequate exposure.

User-Friendly Interface and Design

The Mosaic X camera systems are designed for ease of use, with control possible via tablets or smartphones, making the process more accessible and convenient for users in the field, as well as more economically efficient.

This design reduces or essentially eliminates the need for lengthy and costly training.

“Remarkably, we required almost no training to use the Mosaic camera or to instruct our clients in its usage,”

reported Iwu Emmanuel, a Mosaic customer from Mapersive in Morocco.

This increases the efficiency of the devices in several ways;

  • Less time on boarding means an initial cost savings that many MMS require (such as several days of a paid demo from the producer) 
  • An easier interface means more employees within the company can confidently work with the camera
  • Only one person is needed to both safely drive the vehicle and control the camera system, reducing normal mobile mapping teams from 2 to 1 
  • Control and real-time viewing of images via smartphone, tablet or laptop reduces costs associated with the standard workstation that many larger mobile mapping systems, including those deploying the Ladybug cameras require for controlling, viewing and storing data. 

Image Quality and Efficiency

Mosaic’s camera systems demonstrate a superior approach to image quality and efficiency:

Triggering and Auto Exposure

The Mosaic X camera system exhibits a more responsive auto exposure mechanism. Unlike its counterpart, it can adjust exposure settings more rapidly, ensuring quicker adaptation to varying lighting conditions. This feature is particularly useful in environments where lighting conditions change frequently and unpredictably.

The Ladybug6 camera triggers approximately twice per second, taking about four frames (roughly 2 seconds) for auto exposure to adjust. This slower response can impact image quality in rapidly changing lighting conditions, making the Mosaic X a more adaptable choice in such scenarios.

Efficient Pixel Use and Smaller Overlap

Mosaic cameras utilize pixels more efficiently with a smaller overlap between images. This results in clearer and more consistent panoramic images, enhancing the overall mapping quality.

Reduced “Ghosting” and Superior Stitching

Ladybug cameras sometimes struggle with “ghosting” due to their overlap technique. Mosaic addresses this with a more advanced stitching technique, reducing image artifacts and improving the clarity of the final image.

Fewer Artifacts in Mosaic Data

Compared to Ladybug, Mosaic’s data shows fewer artifacts, a testament to its superior image processing and camera design.

Other considerations

Integration with RIEGL Systems

For RIEGL customers, the choice between Mosaic X and Ladybug6 can be significant. The Mosaic X offers greater flexibility for those not using RiProcess for photo processing, allowing for a wider range of software options without being tied to a specific processing tool. This flexibility can be a crucial factor for users seeking a more versatile and less restrictive imaging solution.

Economic Efficiency

Easily Replaceable Lens Covers

The Mosaic X stands out in terms of maintenance and long-term cost-effectiveness. Its easily swappable lens covers not only reduce the cost of repairs but also add to the convenience of maintaining the camera in optimal condition.

The absence of replaceable lens covers on the Ladybug6 means that any damage to the lens could necessitate a complete replacement, potentially leading to higher maintenance costs over time.

No Onboard Computer Needed

The elimination of an onboard computer to control, view and store data from the camera itself reduces the costs associated with setting up a full mobile mapping camera system in the vehicle. It also means that Mosaic camera system users can get up and go – easily moving from location to location, making use of various vehicles (including rentals), depending on the job at hand. 

Camera Sensor vs Camera System: Mosaic’s Standalone Advantage

As mentioned at the top, there is a difference between ‘camera sensor’ and ‘camera system’. Many of the devices currently on the market are simply camera sensors. Here’s the difference and why it matters.

The Distinction

Ladybug cameras (among several other mobile mapping cameras) are solely camera sensors, requiring additional devices to actually do anything at all. In contrast, Mosaic camera systems are fully-featured, all-in-one, standalone devices, offering a more integrated and efficient solution.

The Mosaic 51 and Mosaic X mobile mapping camera systems contain: 

  • Onboard storage
  • Internal GNSS (with multiple options for plug-and-play external GNSS/INS)
  • Onboard GPU/CPU

Benefits of Mosaic’s Standalone Camera Systems

One of the major differences in equipment is that video storage and GPS are integrated into one solution, making it very simple to build the equipment. We have also used Ladybug but we connected it to a separate laptop via USB and the connection was lost, so we could not use the data we were shooting, and we had to turn the power off and on to reconnect, which was inconvenient. The advantage is that it is stable without such incidents, and almost all functions can be used with the built-in WebUI without the need to develop or install a separate program. Developers can also easily develop with RestAPI.

Synchronization with GNSS for Increased Efficiency

We have owned 2 units of LadyBug5+ since 2018/2019. Since we have our own mobile mapping system, LadyBug cameras were never a priority. The main problem we faced was synchronization with our GNSS since the Ladybug is only the sensor. Very unstable timestamps caused lots of trouble and it took some time for us (and few new firmware’s) to solve the problems.

Last year we have decided to go with new system and Ladybug6 was not our obvious choice, rather the Mosaic X was our priority.  The reason being that is has an onboard integrated GNSS – so synchronization with external GNSS is not a problem. I like the fact that this system is ready to use out of the box and this was important difference to LB6.

Reduced Equipment

Fewer devices are needed in the vehicle, simplifying setup and reducing clutter.

Lower Failure Risk

With fewer components, there’s a reduced risk of system failures, enhancing reliability.

Integrated Data Capture for Use “Out of the Box”

Mosaic systems can independently capture and store images, GPS coordinates, and extremely precise timestamps within their internal SSD.

Versatile Operation

They can function alone with a single operator or integrate into larger systems like RIEGL, Leica, or Trimble, or even custom-designed mobile mapping systems.

 →  Check out the wide range of Mosaic customers and how they are using their camera systems as standalone devices or as part of their unique mobile mapping solutions here.

System Complexity

The Mosaic X was designed as a streamlined, single system. It integrates image capture, GNSS data, and timestamps into one SSD storage device, sufficient for more than one full day’s capture. This integration makes it user-friendly and efficient, ideal for extensive use without the need for constant oversight or additional equipment.

In comparison, the Ladybug6 system is a far more complex and fragile system, involving an intricate setup with numerous cables and additional components. This complexity can be daunting for new users and might require specialized operators, potentially increasing operational costs.
