Embodiment Construction

[0045] The invention proposes the concept of an online calibration system for vehicle-mounted surround view processing. Such as image 3 As shown, the system consists of four parts: overlapping area determination part, feature quantity calculation part, vehicle attitude calculation part and result output part, which constitute an online calibration system. The overlapping regions can be obtained in advance. Except for the overlapping area determination part, the other three parts are all online processing, that is, online calibration processing is performed after each new set of images arrives. A group of images refers to multiple images collected by multiple cameras at the same time, such as one frame of images obtained by each camera at the same time.

[0046] 1. Determining part of overlapping area

[0047] The vehicle-mounted surround view processing system is composed of multiple wide-angle cameras, each of which covers a certain area, and the images are converted from...

Abstract

The invention provides an online calibration processing method for a vehicle-mounted multi-view camera viewing system, which aims to solve the problem of splicing accuracy of a vertical view, caused by vehicle posture change, existing in a vehicle-mounted viewing system. An online calibration system comprises an overlapping area deciding part, a characteristic quantity calculating part, a vehicle posture calculating part and a result output part. Results of the camera viewpoint conversion and spliced processing in various postures are made into a searching table, and the searching stable comprises vehicle posture data and original image position results of all corresponding cameras, such as weighting parameters, and the like, thereby simultaneously carrying out viewpoint conversion and image splicing processing after the vehicle posture data is obtained.

Description

technical field [0001] The invention relates to a vehicle-mounted multi-eye camera surround-view system, in particular to an online calibration processing method for a vehicle-mounted multi-eye camera surround-view system. Background technique [0002] In today's society, cars have become an indispensable means of transportation. While people enjoy the convenience and speed brought by automobiles, automobile traffic accidents, environmental pollution caused by automobile exhaust emissions, and problems caused by traffic congestion have become increasingly serious global social problems. Therefore, there is a great market potential for reducing traffic accidents and improving automobile safety by using various advanced automobile safety technologies, equipment and concepts. [0003] After the 1990s, with the wide application of electronic technology, control technology, sensor technology and new materials in automobile products, automobile safety technology has developed mor...
