The invention relates to a
millimeter-
wave radar and camera rapid joint calibration method, and the method comprises the following steps: S1, enabling a camera and a
radar group to be installed on a motion platform, and enabling the motion platform to be placed at an open flat place; s2, arranging a
corner reflector right in front of the motion platform, adjusting the height of the
corner reflector to be the same as the height of the
radar set, and adjusting the distance between the
corner reflector and the
radar set until the corner reflector appears in the image range of the camera; s3, calibrating the internal parameters of the camera by using the
pinhole camera model and adjusting the radar angle at the same time; s4, determining an initial projection external parameter of the
millimeter wave coordinate
system Xr-Yr to the camera coordinate
system Xc-Yc; s5, adjusting a
yaw angle and a translation distance value in the external parameter by calculating the deviation between the imaging position of the corner reflector in the
image plane and the projection position of the
radar detection point on the
image plane; s6, outputting an internal parameter matrix and an external parameter of the camera, and completing the calibration. The corner reflector is high in reflection intensity and small in size, and better feedback can be obtained.
