Embodiments of the present application provide a ground plane data measurement method, device, mobile device, and readable storage medium, which relate to the field of terrain surveying. The ground plane data measurement method includes: obtaining a point cloud model of the area to be measured and according to the point cloud The model calculates the global ground plane expression of the area to be measured; divides the point cloud model into multiple point cloud groups to be measured and calculates the local ground plane expression of each point cloud group to be measured; based on the global ground plane expression or local ground plane expression The plane expression determines the target ground plane expression of each point cloud group to be measured; the ground plane data of the area to be measured can be obtained according to the target ground plane expression of each point cloud group to be measured, and the ground plane data can be accurately measured.
Description
technical field [0001] The present application relates to the field of terrain surveying, in particular, to a ground plane data surveying method, device, mobile device and readable storage medium. Background technique [0002] At present, with the advancement of agricultural mechanization and intelligentization, more and more automation equipment is operating in the farmland. In order to customize the path and operation data of the automation equipment in the farmland, the determination of the ground plane in the farmland is particularly important. , not only that, but also determine the ground level related data in the farmland, and also pave the way for subsequent measurement of crop height, separation of surface objects (such as obstacles), etc. In the prior art, the determination of the ground level is generally aimed at normal road surfaces, and the existing ground level determination schemes (such as lidar measurement) are not suitable for farmland environments where t...
