The present application provides a video encoding method, decoding method and devices thereof. The video encoding device includes a video capturing unit for capturing a video image; a processing unit for performing compression encoding on a background image in the video image to obtain video compression data and for structuralizing a foreground moving object in the video image to obtain foreground object metadata; a data transmission unit for transmitting the video compression data and the foreground object metadata, wherein the foreground object metadata is data that stores video structuralized semantic information. In the case that the moving objects are large in quantity or in size, the amount of video data can be effectively reduced and the limitation of network bandwidth during transmission can be mitigated.

The disclosure discloses a method, device and system for target tracking. Wherein, the method for target tracking includes that: Global Positioning System (GPS) information of a target object monitored by tracking equipment is acquired (S); Pan/Tilt/Zoom (PTZ) coordinate information corresponding to the GPS information of the target object is obtained according to a pre-stored conversion relationship between GPS information and PTZ coordinate information (S); and the tracking equipment is regulated to control the tracking equipment to monitor the target object according to the PTZ coordinate information of the target object (S). The problem of inaccuracy of a monitoring result of a method for monitoring a tracking target in the conventional art is solved.

The present application relates to the field of monitoring, and discloses a method and a device for obtaining evidences for illegal parking of a vehicle. In the method for obtaining evidences of the present application, a correspondence relationship between shooting positioning parameters of a first camera and a second camera is preset. The method for obtaining evidences comprises: taking a first photo of an illegally parked vehicle using the first camera and obtaining a current first shooting positioning parameter of the first camera; according to the correspondence relationship, calculating a second shooting positioning parameter of the second camera corresponding to the first shooting positioning parameter and controlling the second camera to take a second photo with the second shooting positioning parameter. Thereby the photos of the head and rear of the illegally parked vehicle are obtained simultaneously as the evidences for illegal parking for penalty.

A method and system for people flow statistics is disclosed in the invention, wherein said method comprises: multi-types of classifiers connected in parallel are used to perform the human head detection in the current image, the respective human heads in the current image are determined; the respective determined human heads are tracked to form the human head target movement tracks; and the people flow is counted at the direction of the human head target movement track. It can be seen, a plurality of classifiers connected in parallel are used in the invention, multi-types of human head targets, such as dark colored hair, light colored hair and caps of various colors, and the like, can be detected simultaneously.
