Summary:The invention discloses a binocular camera secondary calibration method and device. The method comprises the following steps: shooting two target targets through a to-be-calibrated camera; respectively extracting left target angular points of the two target targets in the left image, and respectively extracting right target angular points of the two target targets in the right image; extracting a left vanishing point in the left image according to the left target angular points of the two target targets, and extracting a right vanishing point in the right image according to the right target angular points of the two target targets; according to the left vanishing point and the right vanishing point, calculating a pitch angle and a yaw angle of a rotation matrix between the left eye camera and the right eye camera; calculating a left three-dimensional coordinate and a right three-dimensional coordinate of the target angular point based on a monocular principle; and calculating a translation matrix between the
