Abstract:
The invention provides an indoor positioning method and system based on a wireless receiver and a camera, belonging to the field of positioning technology. The method in the invention comprises the following steps: a wireless receiver detects a query WIFI signal transmitted by a target device and extracts a MAC address and CSI of the target device from a query WIFI signal; a server captures the MAC address and the CSI of the target device from the wireless receiver, calculates an incident angle of the target device and the wireless receiver and sends a photographing instruction to a camera which photographs an image and uploads the image to the server; the server obtains the distance between the wireless receiver and the target device through the image pixels, and calculates the position information of the target device according to the coordinates of the wireless receiver. The invention realizes the accurate positioning of the target device by using only a wireless receiver and a camera, so that the cost can be controlled and a real-time calculation can be ensured; the combination of the two beneficial effects can help achieve good positioning results.

Claim (Index 7):
The indoor positioning method as claimed in  claim 6 , wherein in Step S 4 , a method for calculating the distance between the target device and the wireless receiver is as follows:\n S 41 : the corresponding relationship between the distance and the pixels in the image is calculated according to known wireless receiver and camera positions; S 42 : the wireless receiver is taken as a starting point and a human search algorithm is performed along the angle \u03b8 to identify the position of a human body, that is, the position of a target; S 43 : an actual distance between the target and the wireless receiver is calculated according to the pixels of the human body and the wireless receiver.
