Detection of barycenter of planar target based on laser reflective tomography

Reflective tomography imaging Lidar system has been proved a useful approach in remote high-resolution imaging. For space target such as debris, barycenter detection could help monitor their motion status and track. We proposed a barycenter location method based on laser reflection tomography, which could precisely determine the range information and location of barycenter of planar target, whether it is coincident with rotation center or not. Experiments on actual Lidar system was conducted and the results came out that calculated barycenter is about 5 cm away from the real barycenter in detection range of 50 m, which could initially confirm the efficiency of this method.
