The embodiment of the present invention provides a method and system for evaluating the confidence of curb stone extraction. First, the curb contour in the extracted curb data is discretized, and then the discretized curb contour is sampled; finally, the sampling Points are processed to evaluate the confidence of curb contour sampling points. Confidence is used to evaluate whether the extracted curb data meets the standards for high-definition map production. Compared with the quality inspection method using manual measurement in the prior art, which is labor-intensive and has low quality inspection efficiency, the present invention reduces the time for quality inspection after curbstone extraction in high-precision maps, and improves the production efficiency of high-precision maps.
Description
technical field [0001] The invention relates to the field of automatic driving high-precision map production, in particular to a confidence evaluation method and system for curbstone extraction. Background technique [0002] Curbs are markers placed between the pavement and other structures. Curbs are generally required between the partition and the pavement of urban roads, and between the sidewalk and the pavement. Curbs are often required at the edge of the central partition of the highway, the right edge of the carriageway, or the outer edge of the shoulder. [0003] In the field of high-precision map production, curbstones are one of the elements for making high-precision maps. For the quality inspection of curbstones and other elements in high-precision maps, it is first necessary to extract the curbstones and other elements, and then manually check the quality of the extracted curbstones. In the manual detection process, it is necessary to measure the extracted curbs ...
