METHOD AND APPARATUS FOR SCREENING CALIBRATION ROD DATA, AND COMPUTER DEVICE

WIPO Patent Application WO/2022/033421

A1

A method for screening calibration rod data. The method comprises: acquiring target 2D data obtained when a camera photographs a calibration rod, wherein the target 2D data comprises a plurality of pieces of coordinate point data; determining a shape model of the calibration rod, and according to the shape model, performing combination processing on the plurality of pieces of coordinate point data in the target 2D data, so as to obtain a data set that conforms to the shape model, wherein the data set includes one or more data subsets, and the data subset includes a plurality of pieces of coordinate point data after combination; acquiring a rod type proportion of the calibration rod; and screening, from the data set, for a target data subset that satisfies the rod type proportion, wherein the target data subset comprises a plurality of pieces of target coordinate point data after combination. In the present method, data screening can be performed on 2D data photographed by a camera, so as to obtain 2D data that satisfies a calibration requirement. Further disclosed are an apparatus for screening calibration rod data, and a computer device and a storage medium.
