Problems solved by technology

[0005] However, the traditional camera image positioning method is easily affected by factors such as the small coverage area of ​​the camera, the signal is easily blocked by buildings or intentionally blocked by the monitoring personnel, illumination changes, data transmission and large processing capacity, etc. When the camera captures different sides of the same person , Accurate identification is also difficult, and a single distance measurement still cannot meet the high-precision positioning requirements, and it is difficult to achieve the positioning requirements of the target person only by relying on image positioning
Existing technologies rely on single data for positioning, and there are accuracy problems, so the application of indoor positioning technology needs to be further expanded

Abstract

The invention relates to the technical field of target identification and tracking, and discloses a target positioning method and system based on multi-source data fusion and a storage medium, and the method comprises the steps: S1, inputting the scene information of a monitoring area; s2, identifying whether a target enters a monitoring area or not; s3, collecting image information of a target in the monitoring area, and judging the position of the target in combination with scene information of the monitoring area to obtain first positioning of the target; s4, sound information in the target direction in the monitoring area is collected, sound content is recognized, the position of the target is judged in combination with scene information of the monitoring area, and second positioning of the target is obtained; and S5, correcting the first positioning according to the information of the second positioning to obtain accurate positioning. On the basis that the camera collects images to recognize target positioning, target positioning is further corrected and optimized through the collected sound information in the target direction, more accurate positioning is obtained, and the positioning effect is better compared with traditional image recognition positioning.
