Publication number: 20230072145Abstract: The present disclosure relates to a method for screening gradient points, and a method and a system for calculating a gradient. The method for screening gradient points includes: screening the gradient points whose first-order derivatives relative to road offset values are greater than or equal to a derivative threshold, as first-level gradient points; and screening second-level gradient points according to a difference between the road offset values corresponding to two adjacent first-level gradient points, as discrete gradient points. In the method for calculating a gradient, the gradient values of the gradient points between adjacent discrete gradient points are recalculated according to the gradient value of each discrete gradient point and the corresponding road offset value.Type: ApplicationFiled: August 18, 2020Publication date: March 9, 2023Inventors: Yankai TU, Hejie ZHOU
