摘要：

A hybrid lidar system design using the complementarity streak tube imaging lidar (STIL) and time-correlated single-photon counting (TCSPC) lidar is proposed. The new scheme is proposed for the issue that the low sensitivity of STIL system when detecting weak echo signals, and the range walk error of TCSPC lidar system when detecting strong echo signals. The hybrid system is validated by an indoor experiment. The 3D range image of the target made by a 3D printer is obtained, and the makers on the target with a height of 1 cm is clearly identified. The range data have a root mean square error of 2.9 mm. The results show that the applicability for dynamic range of echo signal intensity is improved by the hybrid lidar system.
