| titleOfInvention | External parameter calibration system, method, terminal and readable storage medium |
| abstract | The invention provides an external parameter calibration system, a method, a terminal and a readable storage medium, wherein the calibration method comprises the following steps: acquiring point cloud data obtained by scanning a calibration plate by a laser radar; displaying the point cloud data on a display in a graphic form, wherein the display area of the display is covered with the calibration plate, and the calibration plate comprises at least one diffuse reflection area and at least one specular reflection area with light transmittance; acquiring picture data which is obtained by shooting through a camera and contains the display area; and acquiring external parameters of the laser radar and the camera according to the point cloud data and the picture data. The method removes the matching process between the radar data and the camera data, simplifies the calculation process of the external parameter, and improves the accuracy of calculating the external parameter of the laser radar and the camera. |
