Abstract

The invention provides a panoramic image error correction method and apparatus, applied to a headstock, a tailstock and a vehicle provided with image collection apparatuses on two sides. The method comprises the following steps: solving spatial positions of the image collection apparatuses in a physical coordinate system of a marked site according to a coordinate mapping relationship between a physical marking point and an image point; solving a placement position and posture information of a vehicle body on the marked site by using installation parameters of the image collection apparatuses on front and back positions of the headstock and the tailstock and the solved spatial positions of the image collection apparatuses on the front and back positions on the marked site; updating the coordinates of the physical marking point by using the placement position and the posture information of the vehicle body on the marked site; and performing calibration calculation by using the updated coordinates of the physical marking point and the image coordinates so as to splice the images collected by the image collection apparatuses into a panoramic image. The working efficiency and quality in a calibration process are improved.

Description

technical field [0001] The invention relates to the technical field of panoramic image generation, in particular to a panoramic image error correction method and device. Background technique [0002] With the rapid development of image and computer vision technology, more and more technologies have been applied to the field of automotive electronics. Traditional image-based reversing imaging systems only install cameras at the rear of the vehicle, which can only cover a limited area around the rear of the vehicle. The blind spots around the vehicle and the front of the vehicle undoubtedly increase the hidden dangers of safe driving, and collisions and scratches are prone to occur in narrow and congested urban areas and parking lots. In order to expand the driver's field of vision, it is necessary to be able to perceive the 360° all-round environment, which requires the mutual cooperation of multiple visual sensors and then through video synthesis processing to form a complet...
