A panoramic look-around system pre-calibration device and method

Abstract

The invention relates to a panoramic look-around system pre-calibration device and method. The device comprises a monitoring host, a support, an upper panel arranged at the top of the support and a lower panel arranged at the bottom of the support. The upper panel and the lower panel are both rectangular; the upper panel is made of a transparent material; four corners of the upper panel are respectively provided with a camera connected with the monitoring host, and each camera transmits a shot image to the monitoring host and displays the shot image on a display screen of the monitoring host.The upper surface of the lower panel is coated with a plurality of black and white color blocks, and all the color blocks on the lower panel are arranged in a central symmetry manner relative to the central point of the lower panel; and each color block in the four color blocks in the middle of the lower panel is coated with a circular color block with the color opposite to that of the color block. The panoramic look-around system pre-calibration device and method provided by the invention are convenient to operate, high in calibration precision, good in calibration effect, short in consumed time of calibration operation and low in cost, and can well meet the requirements of practical application.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to a pre-calibration device and method for a panoramic view system. Background technique [0002] In recent years, the automotive electronics industry has been booming, and automotive assisted driving technology, especially the 360° panoramic view system, has been fully developed. Various vehicles can be adapted to different panoramic view system products. Due to the different sizes of different models, the panoramic view It is difficult to find a unified calibration method for system splicing. In view of this situation, every time a 4S store installs a product, it needs to calibrate once with four calibration cloths: front, back, left and right. Especially for the same model, 100 sets of products in the same store need to be calibrated 100 times, and 1,000 stores need to prepare 1,000 sets of calibration cloth. A set of calibration cloth is not cheap, and the servic...

AI Technical Summary

Problems solved by technology

Especially for the same model, 100 sets of products in the same store need to be calibrated 100 times, and 1,000 stores need to prepare 1,000 sets of calibration cloth. A set of calibration cloth is not cheap, and the service life is not long. It is easy to wrinkle and deform, resulting in calibration Accuracy drops

Because different users spread the calibration cloth in different ways, it will lead to different calibration results

This is not only time consuming, but also expensive to maintain

Generally speaking, the calibration devices and methods in the prior art are inconvenient to operate, have low calibration accuracy, and take a long time, which cannot well meet the needs of practical applications and need to be improved urgently.
