Abstract

The invention discloses an intelligent mobile positioning system integrated with multiple positioning technologies, which can locate athletes by calculating the phase difference of Bluetooth signals received by different Bluetooth base stations to obtain the position information of corresponding Bluetooth tags. According to the positioning information of Bluetooth, the corresponding athlete can be located in the image captured by the camera, and the preliminary positioning can be realized without image recognition, and the calculation amount of the video positioning of the camera is very small. Recognize the human body contour of the image captured by the camera to obtain a plane human figure contour map, and match the corresponding 3D human figure contour map in the 3D human figure database according to the plane human figure contour map, so as to restore the athlete's limbs without in-depth analysis of the image information Action, calculation speed is fast, and robustness is high.

Description

technical field [0001] The invention relates to the technical field of Bluetooth indoor positioning, in particular to an intelligent mobile positioning system integrated with multiple positioning technologies. Background technique [0002] In recent years, the location service (Location Based Services, LBS) industry has developed rapidly, and high-precision location information is the basis for providing high-quality location services. Traditional satellite positioning systems, such as Global Positioning System (Global Positioning System, GPS) and Beidou positioning system, have high positioning accuracy in open outdoor environments. However, due to signal strength, satellite positioning signals are easily blocked or interfered, causing satellite The positioning system is inaccurate or even unable to locate in urban canyons and indoor environments. [0003] In order to solve the positioning problem in the indoor environment, many indoor positioning technologies have appeare...
