In the complete vehicle panoramic image processing method and device of the present invention, images are respectively collected by multi-channel image acquisition devices facing different directions on a vehicle; image position data of lane lines appearing in each image are identified and collected; Calculate the spatial physical position of each lane line from the image position data collected by the adjacent image acquisition device about the same lane line; process the data of the spatial physical position to estimate the vehicle body settlement data; use the vehicle body settlement data Perform compensation processing on the calibration data of the image acquisition device; use the compensated calibration data to stitch the images of various channels to generate a panoramic stitching picture; use the road lane line information to process, analyze and monitor the calibration data to avoid splicing dislocation, so that any The panoramic images are always in good splicing effect.
Description
technical field [0001] The invention relates to the technical field of panoramic image generation, in particular to a method and device for processing a panoramic image of a vehicle. Background technique [0002] With the rapid development of image and computer vision technology, more and more technologies are applied to the field of automotive electronics. The traditional image-based reversing camera system only installs a camera at the rear of the car, which can only cover a limited area around the rear of the car. 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 comp...
