LiDAR Test and Evaluation

4D designed, built and installed a light detection and ranging (LiDAR) test fixture that allows the performance characteristics of UAV-deployed LiDAR systems to be assessed.  The LiDAR test stand allows reflective targets to be installed at specified heights and locations on the test stand, with the target reflectivity being variable between 10% and 85%.

A survey marker installed next to the test stand serves as a benchmark for the comparison of data generated by LiDAR systems that are tested.  Positional accuracy, range resolution and accuracy, and data points-per-square-meter – all of which are critically important to validating a systems performance – can all be tested in a controlled fashion.  This is the first test capability of its kind offered for LiDAR system test and evaluation.
