Problems solved by technology

At present, the whole-house monitoring system commonly used in the prior art uses video monitoring or infrared sensor monitoring. Video monitoring involves personal privacy and may easily cause conflicts from the monitored party, while infrared human body sensing can only be used to determine the presence or absence of personnel, and it is difficult to Get precise location information of people

Embodiment

[0040] In this embodiment, the radar data interaction process in the personnel tracking process using the whole house model is as follows: figure 1 shown, which includes:

[0041] 1. Regularly sample the data reported by the radar, convert the sampled data into coordinate data of the whole house according to the house and area label of the radar, and convert the sampling data into coordinate data of the whole house according to the installation position and angle information of the radar, and record the data in the whole house model;

[0042] 2. Create a whole-house global logo for the target data reported by the radar, which is used for whole-house tracking;

[0043]3. During the whole house tracking process, according to the loss / addition of target personnel in the door line area of ​​each detection zone, it is judged whether a cross-domain event has occurred. If a cross-domain event occurs, the cross-domain target personnel information will be inherited to the correspondin...

Abstract

The invention relates to the field of millimeter-wave radar application, and discloses a whole-house personnel tracking method based on a millimeter-wave radar, which protects privacy while ensuring accurate tracking and detection of indoor personnel. The method comprises the following steps: S1, deploying millimeter wave radars in corresponding areas of a whole house; S2, establishing a whole house model; S3, during an application, sampling target personnel data reported by each deployed radar at regular time, converting the target personnel data into whole house coordinate data, and recording the whole house coordinate data in a whole house model; S4, creating a whole-house global identifier for target personnel data reported by each radar in the whole-house model for whole-house tracking; and S5, in the whole house tracking process, judging whether a cross-domain event occurs or not according to the loss / addition condition of the target personnel in the door line area of each detection subarea, and if the cross-domain event occurs, inheriting the information of the cross-domain target personnel to the corresponding newly-added point location in the new area.

Description

technical field [0001] The invention relates to the application field of millimeter wave radar, in particular to a method for tracking people in a whole house based on millimeter wave radar. Background technique [0002] The combination of security technology and intelligence is a major development direction of the whole house intelligent system. At present, the whole-house monitoring system commonly used in the prior art uses video monitoring or infrared sensor monitoring. Video monitoring involves personal privacy and may easily cause conflicts from the monitored party, while infrared human body sensing can only be used to determine the presence or absence of personnel, and it is difficult to Get precise location information of people. Contents of the invention [0003] The technical problem to be solved by the present invention is to propose a whole-house occupant tracking method based on millimeter-wave radar, which can protect privacy while ensuring accurate tracking...
