The Hesai, Velodyne and Riegl lidar combined to the Applanix 15 INS will provide a more repeatable precision and a higher accuracy due to higher performance INS.
The product design has been done in respect to small tolerance values that the boresight angles and lever arms measurements doesn’t change whenever you swap modules. We recommend one lidar calibration per year for your unit.
Yes. If you don’t need to use the lidar then you can fly without the lidar and take advantages of the high performant INS. We also provide all the internal and external orientation parameters (EOPs, IOPs). Using the combination of your IMU with the camera calibration profile, you can create a very accurate orthophotos without the need to us ground control point in your photogrammetry processing. Use them just as check points !
It is not recommended to fly the lidar in the rain. The rain will affect the quality of the data. No lidar systems should be operated in the rain.
Strip adjustment allows to reduce the point mismatch from different flight lines hereby reducing the thickness and increasing the relative precision of the overall point cloud.
Lidar surveys are conducted using multiple flight passes or scan lines to cover large areas. Strip line adjustment helps improve the overall elevation accuracy of the collected data by minimizing vertical discrepancies between adjacent strips. In cases where LiDAR data is collected over multiple dates or flights, strip line adjustment helps maintain consistency and coherence across the entire dataset. This is essential for accurate change detection analysis.
All Balko computer modules come with a 12-month warranty, the lidar modules respect the manufacturer’s warranty terms and conditions. A 2-yr and 3-yr warranty extension is also available on request.
The accuracy depends on the configuration, however the configuration which offers the best accuracy is the Riegl with an APX-20. With this configuration a relative precision of 1 cm and accuracy of 2 cm XYZ can be obtained before doing any processing optimization.
This depends on the configuration; a lighter payload will be able to cover more area than a heavier payload. However, when flying at 100 m AGL and at 10 m/s you can cover approximately over 5 sq km per day.
