Room wall contour recognition method and terminal equipment based on millimeter wave radar

Abstract

The present invention is applicable to the technical field of contour recognition, and provides a room wall contour recognition method and terminal equipment based on millimeter wave radar. Obtain the data matrix of the number of sampling points corresponding to each frame; process the point cloud information of the data matrix of each frame to obtain the point cloud information of the preset number of frames; perform clustering processing on the points corresponding to the point cloud information in turn to determine the first Target clustering point; determine the second target clustering point according to the number of clustering point elements contained in each first target clustering point; calculate according to each second target clustering point, determine the wall outline range, so that it can automatically Identify the range of the wall outline and limit the range of the reported wall outline to effectively suppress false targets, and the erection of the millimeter-wave radar is simple, reducing the complexity of the erection and improving the flexibility and reliability of the radar.

Description

technical field [0001] The invention belongs to the technical field of contour identification, and in particular relates to a method and terminal equipment for identifying the contour of a room wall based on a millimeter wave radar. Background technique [0002] Millimeter-wave radar is a sensor solution for indoor member detection. When the millimeter-wave radar is installed indoors, due to the complex indoor environment, stationary objects, walls and other targets will generate echoes, which may interfere with the detection of real targets. Generate false targets. Because the echoes of these false targets have undergone multiple reflections, they tend to appear outside the areas where people can actually appear, such as outside walls. Millimeter-wave radars may be installed in different scenarios, and it is difficult to limit the range in software for each scenario. Each radar needs to be configured to limit the range of the radar according to the actual scene during ere...

Millimeter-wave radars may be set up in different scenarios, and it is difficult to limit the range of each scenario in the software

When erecting each radar, it is necessary to configure the radar to limit the range according to the actual scene, which greatly increases the complexity of erection and limits the flexibility of radar use.
