Panoramic parking calibration method and device, and storage medium

Abstract

The invention provides a panoramic parking calibration method and device, and a storage medium. The method comprises steps of controlling cameras to collect fisheye source images of a corresponding region, enabling the cameras to be a front camera, a rear camera, a left camera and a right camera which are installed on a target vehicle, and enabling the fisheye source images to comprise chessboardcalibration plates laid at the periphery of a vehicle body of the target vehicle; calibrating the coordinates of the central point of each fisheye source image, and calibrating the coordinates of fourpredetermined angular points of a chessboard calibration board in each fisheye source image; and generating an image relationship lookup table between a fisheye source image coordinate point and a panoramic image coordinate point according to the central point coordinate, the four predetermined angular point coordinates and a pre-input actual position parameter, and generating a panoramic image according to the image relationship lookup table. The method is advantaged in that the panoramic image can be generated after the image relation lookup table is obtained by calibrating the center pointand the four corner points, and the method is simple, rapid and short in consumed time.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to a panoramic parking calibration method, device and storage medium. Background technique [0002] For a long time, when the driver parks the vehicle in the parking space, he can only rely on the rearview mirror to roughly observe the surrounding environment of the vehicle body, or only rely on a single rearview camera to observe the obstacles behind the vehicle body, which has a large visual blind spot . In order to solve the problem of parking safety, an ultra-wide-angle fisheye camera is installed on the front, rear, left, and right of the car body, and a synthetic bird's-eye view of the sky is synthesized through the acquired images. The real-time images around the vehicle body can be seen through the bird's-eye view on the display screen, which can clearly show the relative position of obstacles and the vehicle body. In this way, how to synthesize a bird's-eye vi...
