CoPre is a powerful software ecosystem developed by CHCNAV that enables users to process mobile geospatial mapping data quickly and efficiently.

CHCNAV CoPre Lidar Data Processing Software

CHCNAV LandStar

Marine Systems

Made of macromolecule polyester carbon fiber and Kevlar fiber-glass weighting 15 kg without sensors.CoPre desktop software provides instant access to raw data from all the CHCNAV LiDAR systems. Whether you want to process data from the compact AlphaAir 10 mobile mapper for UAVs, perform massive data processing from the vehicle-mounted AlphaPano or Alpha3D system, or get the results of your corridor mapping project with the AlphaUni 20 or AlphaAir 2400 on a helicopter, CoPre supports all your mapping scenarios.

For experts searching to optimize their data quality further, CoPre features an advanced processing mode. It handles the layering problems of multiple point clouds and improves relative accuracy through an efficient strip adjustment algorithm. Additional use of ground control points (GCP) is available to improve the absolute accuracy of the point cloud. The advanced calibration and optimization technology results in a point cloud thickness that is 30% less than similar products provided on the market.

All LiDAR data processing starts with the first and foremost step of trajectory generation. CoPre is powered by the accurate and efficient algorithm developed by CHCNAV to process captured raw data, including trajectory (POS) files, LiDAR data, and RGB images. Multiple data sets can be processed simultaneously to increase workflow efficiency, solving the problem for SLAM-based units of updating a map of an unknown environment while simultaneously keeping track of the location within it.

CoPre includes different powerful options to check the data after the processing steps. It supports massive data set visualization with multiple colorization options. Its automatic trajectory slicing and stratification checking allow quick detection of misalignments across the entire data set. Elevation accuracy can be automatically verified by importing elevation control points. Multiple accuracy reports are available to address quality control requirements.
