Abstract

The invention relates to a model establishing method and device, a storage medium and electronic equipment. The method comprises the following steps of acquiring target position information of a plurality of target points corresponding to a target detection object in a simulation radar visual field, determining a target reference plane according to the target position information of the pluralityof target points, the distance from each target point to the target reference plane being within a target range, determining a target included angle between a target laser ray irradiated to the targetpoint and the target reference plane, and according to the target position information and the target included angle, generating a model of the target detection object in the simulation radar visualfield, so that use of parameters with relatively low accuracy can be avoided, and the accuracy of the radar modeling effect can be improved.

Description

technical field [0001] The present disclosure relates to the field of lidar modeling, and in particular, relates to a method, device, storage medium and electronic equipment for establishing a model. Background technique [0002] Lidar modeling is the process of simulating the transmission of laser rays to the target detection object through the transmission medium, and returning to the laser receiving device after changing the transmission direction under the reflection of the target detection object surface. The modeling method of lidar in the related technology basically needs to determine the receiving power of the radar through the transmission power of the radar, the reflectivity of the surface of the target detection object, the receiving aperture of the radar, the transmission loss and the loss of the radar system, and then according to the receiving power of the radar The power shows the process of radar propagation. [0003] However, since parameters such as radar...

Problems solved by technology

[0003] However, since parameters such as radar transmission power, receiving aperture, transmission loss, and radar system loss are usually found through user manuals, the influence of the specific working environment on the above parameters is not considered, and the reflectivity of the surface of the target detection object refers to The reflectance corresponding to the material on the surface of the target detection object. When determining the reflectance of the target detection object surface, the reflectance corresponding to the material material close to the surface material of the target detection object is often used as the reflectance of the target detection object surface. There is a certain error between the determined reflectivity parameters and the actual reflectivity. If any of the above parameters is inaccurate, it will cause a large difference between the simulation effect of the lidar model and the actual radar propagation situation.

In other words, the current lidar modeling process involves too many parameters with low accuracy, which may easily cause the problem of poor accuracy of the generated lidar model
