DJI LiDAR Range Finder(RS)

Product Information

The capability to process 6,000 images per 1 GB of free memory is based on the test results using aerial photographic data with 80% frontal overlap, 70% side overlap, top-down shooting, and GPS information. Results can vary based on how much your images overlap and how complex the scene is.

Unobstructed, free of interference, when FCC compliant. Maximum flight range specification is a proxy for radio link strength and resilience. Always fly your drone within visual line of sight unless otherwise permitted. In contrast, the drone enabled us to access difficult-to-reach areas and LiDAR ensured accurate data collection, even in low-light environments. M300 RTK-L1 combo took two days to collect the data: A process which would have taken three weeks using traditional methods; Permanent certificates can be upgraded to any software version within one year after activation and binding. The paid update period shall start after one year. An upgrade and maintenance fee must be paid to upgrade to any software version released during the paid update period.For more information on the upgrade fee for the Permanent version, please refer to the "DJI Terra Permanent Version Upgrade & Maintenance Fee Rules".

This DEM, for instance, shows a large shingle spit (in the middle of the model) which is a major factor in the retreating coastline. Processing capability of 400 images/1GB free memory is based on 80% overlap in heading, 70% overlap in side direction, downward looking image data with GPS information, which may vary depending on image overlap and scene texture.

The Zenmuse L1 is designed with an industrial-grade IMU. In typical operating scenarios, the L1 delivers IMU accuracy of 0.025°(roll/pitch)/0.15°(yaw). For further reliability and precision, a vision sensor for positioning accuracy and a dual-frequency GNSS receiver have been incorporated into the solution. This allows the L1 to deliver a relative survey-grade accuracy of 5cm and absolute accuracy of 10cm while flying at an altitude of 50m. The DJI Zenmuse P1 provides high accuracy without Ground Control Points (3cm horizontally / 5cm vertically) and high efficiency as it is able to cover 3 km2 in a single flight.

Why use DJI drones for LiDAR mapping?

On the basis of our surveys, the system proved to be even better than the accuracies quoted as part of the product specifications. How accurate is a drone survey? It's an important and frequently-asked question when it comes to aerial mapping. DJI M600 has 2 D-RTK GNSS antennas receiving the GPS L1/L2 and GLONASS F1/F2 constellations, which are resistant to strong magnetic interference and allow centimeter-level positioning.

However, it is also important to point out that the true average error (converting all negatives to positives in the Accuracy Difference column and basing the calculation on the absolute error values) is 0.031. This shows that the L1 achieved 31mm vertical accuracy - which is still a highly impressive return. heliguy™ is starting a geospatial workflow course through the Learning Management System, which will include L1 best practices and post-processing in DJI Terra and TerraSolid.

The DJI RS 3

Though the technology has been around for more than half a century, the disruptive nature of Light Detection and Ranging (LiDAR) data has gained centerstage across various industries only in the last decade or so. In the surveying industry, LiDAR technology is widely accepted as an important piece to the puzzle of accurate reality models. O3 Pro transmission technology enables the transmission system to offer a 20,000-foot on-ground transmission distance with end-to-end ultra-low latency, which DJI positions as a huge upgrade from traditional WiFi transmission. Video is transmitted in 1080p 60 frames-per-second and provides live audio monitoring at 16-bit 48 kHz. The left view shows the end of the spit from an aerial perspective colourised with realistic RGB colour, while the right shows a cross-section of the same model coloured by elevation. The L1 is the only aerial LiDAR sensor to support both a line scan mode and a non-repetitive scanning pattern – a unique technology developed by Livox. In this mode, as the integration time grows, so does the area being scanned inside the field-of-view (FOV). Following this methodology increases the likelihood of objects and other details within the FOV being detected. And the longer the drone LiDAR sensor scans an area, the higher the resolution of the data becomes (when compared to regular line scan). Speaking of FOV, the L1’s non-repetitive scanning mode spans 70.4° (horizontal) × 77.2° (vertical). The Hexadrone Tundra is a heavy-duty, customizable drone built for extreme conditions. It can accommodate LiDAR sensors and offers precise control for accurate mapping. Its durability and flexibility make it an appealing choice for specialized mapping projects. Built in France.
