Abstract

The invention provides a calibration method and device, roadside equipment and a computer readable storage medium, and the method comprises the steps: obtaining a sample image and sample point cloud data; calculating a first conversion matrix of the coordinate system of a to-be-calibrated object relative to the coordinate system of a data acquisition device; obtaining the overlap ratio of the edgepoints projected to the sample image and the edge features of the sample image; and optimizing the first conversion matrix to obtain an optimized first conversion matrix so as to calibrate the to-be-calibrated object. According to the technical scheme, point cloud data are acquired through the data acquisition device, and the alignment characteristic of the edge characteristics of the point clouddata and the sample image is utilized to optimize the first conversion matrix of the coordinate system of the to-be-calibrated object and the coordinate system of the data acquisition device, so thatthe to-be-calibrated object is calibrated, the whole calibration process is simple and rapid, is not influenced by the outdoor environment of a road, and the method is more flexible to use and has higher calibration accuracy.

Description

technical field [0001] The present application relates to the technical field of intelligent transportation, in particular to a calibration method, device, roadside equipment and computer-readable storage medium. Background technique [0002] With the development of autonomous driving technology, self-driving vehicles gradually appear on the road. Vehicles automatically plan driving routes by collecting surrounding environment information during driving. The collection of surrounding environment information mainly relies on cameras such as roadside cameras. The camera is used as a sensor to collect image information to achieve vehicle-road coordination, but the camera mainly collects two-dimensional images, and accurate calibration is required to convert effective three-dimensional image information. [0003] In the prior art, the camera calibration method requires the use of special calibration boards or markers, etc., which cannot be flexibly used on the road, and is easil...
