Problems solved by technology
Among them, there are usually multiple electric police cameras installed at an intersection, but each camera works independently and performs the monitoring of motor vehicles separately, while the vehicle is in a continuous movement at the intersection, and the monitoring of a single camera has limitations. Sometimes it will lead to errors and deviations in the monitoring results, that is, the monitoring accuracy of the camera needs to be improved

Embodiment Construction
[0026] The multi-directional electric police camera scene synthesis and comprehensive monitoring method of the embodiment of the present invention is applied to video surveillance, and is used to process pictures taken by multiple electric police cameras located in different directions of the same scene. For example, the above-mentioned same scene may be an intersection, and the method of this embodiment may be used to process pictures taken by multiple electric police cameras monitoring the intersection. In the following description, the intersection is taken as an example, but the specific implementation is not limited to the intersection. For example, it can also be applied to T-shaped intersections, or X intersections, Y intersections, etc., or not necessarily at intersections, and can also be applied In other layouts, the principle is similar to the processing of pictures taken by cameras in different directions in the same scene. see figure 1 The application scenario sh...

The invention provides a scene synthesis and comprehensive monitoring method for electronic police cameras in multiple directions and a scene synthesis and comprehensive monitoring device for the electronic police cameras in the multiple directions. The method comprises the following steps of obtaining multiple split-view pictures, and virtually synthesizing the multiple pictures to obtain a virtual full-view picture of a looking-down scene, wherein the multiple split-view pictures are respectively taken by the multiple electronic police cameras; determining the same motion object in the multiple split-view pictures; based on the split-view pictures and the virtual full-view picture, obtaining the motion track of the motion object in the virtual full-view picture; according to the motion track, comprehensively monitoring the motion object. By applying the method and the device, the electronic police cameras monitor the motion of the object more accurately.
Description
technical field [0001] The invention relates to video monitoring technology, in particular to a multi-directional electric police camera scene synthesis and comprehensive monitoring method and device. Background technique [0002] At present, a gantry is usually installed at the intersection of the street, and an electric police camera is installed on the gantry to monitor the motor vehicles passing through the intersection, such as monitoring violations such as running a red light and pressing a line, and is also used to count traffic flow, etc. . Among them, there are usually multiple electric police cameras installed at an intersection, but each camera works independently and performs monitoring of motor vehicles separately, while the vehicle is in a continuous movement at the intersection, and the monitoring of a single camera has limitations. Invariance, sometimes lead to errors and deviations in the monitoring results, that is, the monitoring accuracy of the camera ne...
