[0002] An in-vehicle surround view panoramic system is a visual assistance system composed of several groups of cameras arranged on a vehicle and their control units. Generally, in a passenger vehicle, the system can be put into use after undergoing an installation and calibration process. In the field of commercial trailers, since the tractor head and the towed cargo compartment do not have a fixed relationship but a many-to-many relationship, generally, the control unit is arranged on the tractor head, and several cameras need to be arranged on the cargo compartment. When the tractor head disconnects from the cargo compartment and connects to another cargo compartment, the calibration data of the cameras on the cargo compartment in the control unit of the tractor head does not update accordingly with the connection of the new cargo compartment, resulting in a mismatch between the data and the cargo compartment and thus a poor display effect.
[0003] In the prior art, in order to solve the problem of the mismatch between the cargo compartment and the tractor head, the commonly used solutions are either not to arrange cameras on the cargo compartment or only to arrange a camera at the rear of the cargo compartment that does not participate in panoramic synthesis for separate display, which leads to problems such as blurred images of the rear part of the vehicle and missing images directly behind in the panoramic image.

[0029] In the prior art, in order to address the problem of mismatch between the cargo compartment and the vehicle head, the commonly used solutions are either not to arrange cameras on the cargo compartment or to arrange only one camera at the rear of the cargo compartment that does not participate in panoramic synthesis for separate display, which leads to problems such as blurred images of the rear of the vehicle and missing images directly behind in the panoramic image.
[0030] Based on the above problems, the embodiment of the present utility model provides a matching system for the front and rear body calibration data of a commercial vehicle panoramic system. The new vehicle head can obtain the correct camera parameters of the cargo compartment from an additional storage unit, so as to be able to draw a complete and correct panoramic image.
