Research on the adaptive joint spatial synchronization method for lidar and binocular camera

Abstract

Binocular cameras and lidars are widely used in the safety monitoring of the three-span section of transmission lines due to their good complementary characteristics. The existing spatial synchronization methods for binocular cameras and lidars have low accuracy in synchronous measurement due to the calibration process being overly dependent on manual point selection. In this paper, the data of the camera and lidar sensor are aligned spatially, and a joint calibration method is adopted to achieve the spatial synchronization of the lidar and binocular cameras, making the data obtained from the fused measurement after synchronization more accurate. The simulation test results show that compared with using binocular cameras alone or lidars alone for spatial measurement, the fused measurement results using the adaptive joint spatial synchronization method proposed in this paper are more accurate, thereby verifying the effectiveness of this method.
