Problems solved by technology

However, this method needs to use multiple cameras to capture multiple sets of lane lines, and cannot fit the ground in real time; at the same time, this method only uses three points that are not on the same straight line to determine a plane, and there is a large error ; In addition, this method only fits a ground plane and cannot obtain the real ground

Abstract

The embodiment of the invention discloses a ground segmentation method based on stereoscopic vision. The method comprises the following steps: acquiring three-dimensional point cloud data of a targetscene image; acquiring three-dimensional point cloud data of a lane line in the target scene; determining an estimated ground according to the three-dimensional point cloud data of the lane line, anddetermining a ground point cloud of the target scene image when the distance between the three-dimensional point cloud data of the target scene image and the estimated ground meets a set condition; and determining the ground of the target scene image according to the ground point cloud of the target scene image. The embodiment of the invention further discloses a ground segmentation device based on stereoscopic vision, vehicle-mounted equipment and a storage medium.

Description

technical field [0001] The present invention relates to the field of intelligent driving, in particular to a ground segmentation method, device and vehicle-mounted equipment based on stereo vision. Background technique [0002] In the car driving scene, the 3D point cloud of the target scene image collected by the binocular camera is very dense. For example, a 1920*1080 picture has more than 2 million corresponding 3D point clouds, far The number of 3D point clouds generated by more than one lidar. Therefore, if the ground plane collected by the target scene image can be segmented, the calculation operation of the subsequent 3D point cloud can be significantly reduced. [0003] In the known technology, it is disclosed that a plane is determined by a camera and any straight line in its field of view, and four planes are generated by using four cameras on the front, rear, left, and right sides of the vehicle body, and then the intersection lines of each plane are calculated s...
