Intelligent positioning system and its positioning method based on multi-frequency information fusion

Abstract

The invention discloses a multi-frequency information fusion-based intelligent positioning system and a multi-frequency information fusion-based intelligent positioning method. The intelligent positioning system comprises a plurality of electric three-variable CCD (charge coupled device) cameras which are provided with controllable holders and are distributed in a monitored region; the CCD cameras are communicated with a terminal; each object to be monitored carries an electronic tag; a plurality of wireless sensors are arranged on the periphery of the monitored region; the wireless sensors acquire the data information of the electronic tags; meanwhile, each wireless sensor is communicated with the terminal; and the terminal tracks the position of the object to be monitored according to the acquired data information. By the method, the aim of positioning and tracking accurately is fulfilled by performing information analysis and fusion on shot data.

Description

technical field [0001] The invention relates to an intelligent positioning system, in particular to a positioning system that can be applied to real-time monitoring and positioning of multiple targets in complex situations, and can automatically find and monitor the specific orientation of the target to be monitored, which belongs to the automatic processing of computer images technology field. Background technique [0002] In video surveillance in many places, due to the randomness of the whereabouts of the objects to be monitored, the wide range of activities and the complex environment on site, it is difficult to ensure that the objects to be monitored are always covered by the camera field of view. If multiple cameras are installed, the field of view can be solved. However, due to the random movement of the object and the limitation of the environment, it is difficult to coordinate the work of multiple cameras and automatically switch to track the target. At the same tim...

Problems solved by technology

[0002] In video surveillance in many places, due to the randomness of the whereabouts of the objects to be monitored, the wide range of activities and the complex environment on site, it is difficult to ensure that the objects to be monitored are always covered by the camera field of view. If multiple cameras are installed, the field of view can be solved. However, due to the random movement of the object and the limitation of the environment, it is difficult to coordinate the work of multiple cameras and automatically switch to track the target. At the same time, it is impossible to use a single camera for precise positioning

[0003] At present, there is no good solution in China. Most of them model the on-site map and record the coordinates of all cameras. Using image processing technology to find the target through the camera, and then match it to the map model to get the approximate orientation. When the background around the target is complex or moving When the randomness is large, good tracking effect cannot be guaranteed
