Abstract
The panoramic surround view system in the vehicle can control the projection device of the vehicle to project the preset pattern on the ground around the vehicle, acquire the plurality of target photographs including the preset pattern, and generate the target calibrating data of the surround view cameras according to the plurality of target photographs, so that the surround view cameras of the panoramic surround view system can be calibrated by using the target calibrating data to obtain the panoramic surround view image. Therefore, when the user needs to re-calibrate the calibrating data of the image splicing of the panoramic surround view system of the vehicle, the calibrating process can be completed by only by using the projection device of the vehicle, without using a special calibrating site and equipment, thus simplifying the calibrating operation steps and saving time.
