Abstract:
     The 3D active real-time positioning system based on binocular vision and laser ranging consists of three parts of vision processing subsystem, control subsystem and mechanical mechanism. The target image the video camera under the control of image acquisition card obtains is processed in the vision processing computer to obtain the 2D position information in image coordinate sent to the public memory area. Then, the control computer obtains the position information from the public memory area, performs coordinate conversion and real-time programming, outputs via D/A converter board to the driver to drive the motor and controls the laser via the angle encoder feedback loop to irradiate the target accurately. Finally, the depth information the range finder measures is fed back to the vision computer to obtain the 3D position information of the target. The system has the advantages of high distance precision, high activity, high real-time performance, low cost, etc.
