Problems solved by technology
However, with the continuation of the time after the case occurred and the expansion of the moving range of the suspected target, human inspection of the surveillance video can no longer meet the requirements of handling the case.
At present, the automatic tracking and detection of specific targets such as objects and personnel are only tracked and monitored for a single specific target.
Tracking and monitoring of a single specific target has little effect on case detection due to problems such as little tracking information, incomplete tracking process, and inconspicuous tracking effect

Embodiment Construction
[0048] Such as figure 1 As shown, a monitoring and tracking method for the continuous movement of a specific target and a suspected target includes the following steps:
[0049] Step 1. Establish an object recognition model and a description model for specific targets and suspicious targets within the range of the same camera
[0050] First, the video stream data is preprocessed into pictures, and the residual network and Inceptionv1 model are added to the original yolov3 algorithm to establish a machine automatic identification model, and the processed pictures are input into the model to complete the automatic identification of items. For the accompanying movement of a specific target and a suspected target, within the monitoring range of the same camera, calculate the contact area between the specific target and other targets, determine the suspected target according to the contact area, and monitor and track the accompanying movement of the specific target and the suspected ...

The invention discloses a monitoring and tracking method for continuous movement of a specific target and a suspected target, belonging to the technical field of urban video monitoring security. The method includes the following steps: after specific targets such as items and personnel are missing at a surveillance camera, the machine automatically recognizes the item model to perform specific target recognition on the surveillance video within a specific range; after completing the specific target recognition, according to the The contact area with the specific target in the monitoring screen determines the suspected target; tracks the accompanying movement of the specific target and the suspected target within a specific range, and obtains the accompanying movement trajectory of the specific target and the suspected target within a specific range; according to the accompanying movement of the specific target and the suspected target Move the trajectory and predict the next possible monitoring area. The police investigators can adopt the method of squatting in advance in the area where specific targets and suspected targets may appear, so as to reduce the time for solving cases, greatly improve the efficiency of case handling, and reduce the waste of human resources.
Description
technical field [0001] The invention relates to the technical field of urban video surveillance security, in particular to a monitoring and tracking method for continuous movement of specific targets and suspected targets. Background technique [0002] With the advancement and development of science and technology, in the field of computer vision, applications such as face recognition, unmanned driving, and unattended video surveillance have emerged. With the increase of high-tech crimes, video surveillance at the scene of the crime, tracking and monitoring of specific targets and suspected targets are of great significance for locking suspects and reducing the time to solve the case. However, due to the limitations of storage devices and video shooting technology, there have been problems such as video accumulation, manual screening is difficult and time-consuming. If the detection, positioning, tracking and identification of targets in surveillance scenes can be realized ...
