Method and system of calibration of panoramic parking based on touch screen operation

The invention provides a method and system of calibration of panoramic parking based on touch screen operation. Images shot by a camera on one side of a selected vehicle are displayed on a touch screen, positions of calibration points on the touch screen of the images clicked by a user according to a preset order are obtained, the positions are brought into a preset conversion algorithm to figure physical locations of the corresponding calibration points of the positions in a preset coordinate system based on the order, the figured physical locations and physical locations of the corresponding calibration points in the preset coordinate system carry out deviation calculation to obtain deviation degree of the corresponding camera, the images shot by the corresponding camera carry out compensation calculation according to the deviation degree, the previous steps are repeated until all cameras are corrected, and images shot by all the cameras after the compensation calculation carry out splicing to obtain a panoramic image around a vehicle body.
