Abstract
A road slope predicting method, a device, and a storage medium are disclosed. The road slope predicting method includes obtaining a road image of a road by a camera, detecting a first image lane line and a second image lane line of the road from the road image, setting a number of road image segmentation points along a road image center line of the first image lane line and the second image lane line respectively by means of the corresponding road image segmentation points, determining the pitch angle of the camera with respect to the road plane at each road space segmentation point; based on the internal and external parameters of the camera and the pitch angle, a space coordinate of each road space segmentation points is calculated in a recursive man. A road model of the road is constructed based on each space coordinate.
