Mono Camera and Laser Rangefinding Sensor Position-Pose Measurement System
Precision of translation measurements along the camera′s optical axis is generally much lower than that of which is perpendicular to the optical axis in monocular vision measurement due to the inherent limitation of the system. First of all, mathematical model is analyzed to explain the cause, then a high-precision laser rangefinding sensor (DLS) is installed near the camera to construct the Monoocular Camera-DLS pose measurement system, which will improve the precision of translation measurements along the optical axis with DLS measurements; Finally, principle of the system′s calibration and data fusion method are conducted. Experimental results show the feasibility and validity of the position-pose measurement system.
