Problems solved by technology

[0002] In the daily driving process, the driver is located in the cabin, and needs to rely on left and right rearview mirrors, central rearview mirrors, windows, and windshields to observe the surrounding conditions of the vehicle body when observing the surrounding conditions of the vehicle body. Therefore, there are many visual blind spots and cannot Reasonably judge the distance between the vehicle body and the surrounding area

Embodiment Construction

[0076] The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure, but not to limit the present disclosure.

[0077] A vehicle equipped with a panoramic system, the technicians calibrate it based on the images of the scene captured by the four cameras set on the front, rear, left, right, and right of the vehicle. If the user is using the vehicle, the position of any camera occurs changes, the angle or range of the captured image will change. If the panoramic system of the vehicle still follows the calibration results that the vehicle has completed before the production line is completed, the images of the scene captured by the four cameras on Stitching will result in deformity of the panoramic image, and users cannot clearly observe the scene around the vehicle, which may cau...

Abstract

The invention relates to a panoramic system automatic calibration method and a device, a readable storage medium and electronic equipment. The method comprises the steps of obtaining a panoramic imagecurrently output by a panoramic system of a vehicle; performing image quality evaluation on the panoramic image; if the image quality evaluation value is smaller than a first preset threshold value,updating target parameters of an image acquisition device of the vehicle according to the panoramic image and the multiple frames of images; according to the target parameters, splicing the multiple frames of images again to obtain an updated panoramic image; re-executing the step of performing image quality evaluation on the panoramic image until the image quality evaluation value is greater thanor equal to the first preset threshold; and calibrating the panoramic system of the vehicle according to the target parameters. Thus, after the quality of the panoramic image is reduced, the panoramic system can be automatically calibrated again in time, the quality of the panoramic image is recovered, and safety accidents caused by the fact that a user cannot clearly observe scenes around the vehicle due to the fact that the quality of the panoramic image is reduced are avoided.

Description

technical field [0001] The present disclosure relates to the technical field of vehicles, and in particular, to an automatic calibration method, device, readable storage medium and electronic device of a panoramic system. Background technique [0002] In the daily driving process, the driver is located in the cabin and needs to rely on the left and right rearview mirrors, central rearview mirror, windows, and windshield to observe the surrounding conditions of the vehicle body. Therefore, there are many blind spots, and it is impossible to observe the surrounding conditions of the vehicle body. Reasonably judge the distance between the body and the surrounding. In order to reasonably judge the distance between the vehicle body and the surroundings, the vehicle visual assistance system has developed from the rear-view camera to observe the reversing image behind the vehicle, to a panoramic system that observes the image around the vehicle through four cameras in the front, re...
