Abstract

The invention relates to the technical field of data processing, in particular to a method and device for detecting the number of target objects in a monitoring area, and solves the problem that the detection efficiency is low when the number of the target objects in the monitoring area is manually detected. The method comprises the following steps: determining the total number of target objects of each to-be-processed video frame associated with specified acquisition time, screening out each group of to-be-processed video frames with a shooting overlapping area from each to-be-processed video frame, and for each group of to-be-processed video frames, determining repeated target objects at least based on the identified three-dimensional coordinates of the key points on each target object in the ground coordinate system and the re-projection of the key points, and obtaining the number of the target objects in the monitoring area after deleting the repeated target objects. Therefore, the number of the target objects in the monitoring area can be effectively detected, the statistical efficiency of the number of the target objects in the monitoring area is improved, and the accuracy of the number detection of the target objects is ensured.

Description

technical field [0001] The present disclosure relates to the technical field of data processing, and in particular to a method and device for detecting the number of target objects in a monitoring area. Background technique [0002] For places with high safety requirements such as gymnasiums, shopping malls, factory workshops, and elevators, it is necessary to monitor the number of people at all times to avoid potential safety problems caused by overcrowding in the monitoring area. [0003] At present, surveillance cameras are usually deployed in the surveillance area to monitor the number of people, and relevant personnel are specially deployed to view the images captured in the surveillance area. [0004] In this way, when there are multiple cameras in the monitoring area, it is difficult to manually detect the total number of people in the monitoring area due to overlapping areas between different cameras, which not only requires additional labor costs, but also has low d...
