Problems solved by technology
[0002] In the prior art, area detection is basically carried out by camera devices and corresponding image recognition technology. However, if image acquisition is performed in a public area, there will be no major problems, but if image acquisition is performed in a private space, people's Daily behaviors are recorded in detail, which is extremely easy to violate the privacy of users, and if leakage occurs, it will cause many hidden dangers
At the same time, image processing requires a large amount of calculation, which requires high computing power of the processing module, so the cost is also high

The present application relates to an area detection method and device, including: acquiring a radar detection signal of a monitoring area; obtaining a moving target according to the radar detection signal; tracking the moving target to obtain the trajectory of the moving target; The track of the target is used to obtain the starting position and the ending position of the moving target; according to the starting position and the ending position, the entrance and exit areas of the monitoring area are determined. Compared with the prior art, the above-mentioned technical solution provided has the following advantages: the present invention obtains the track of the moving target by analyzing the radar detection signal reflected by the scene and processing it, and then according to the start and end position information of the track of the moving target The indoor entrance and exit area detection replaces the area detection by the pattern recognition method in the prior art, which can effectively reduce the deployment cost of the corresponding equipment, and at the same time can guarantee the privacy of users during the detection of specific areas.
Description
technical field [0001] The present application relates to a positioning method, in particular to an area detection method and device. Background technique [0002] In the prior art, area detection is basically carried out by camera devices and corresponding image recognition technology. However, if image acquisition is performed in a public area, there will be no major problems, but if image acquisition is performed in a private space, people's Daily behaviors are recorded in detail, which is extremely easy to violate the privacy of users, and if leakage occurs, it will cause many hidden dangers. At the same time, processing the image requires a large amount of calculation, which requires a high computing capability of the processing module, and thus the cost is relatively high. [0003] As a kind of electromagnetic wave detection equipment, radar has been paid more and more attention by researchers due to its high sensitivity, no need for direct contact, and strong penetra...
