Embodiment 1
[0019] figure 1 A flow chart of a method for detecting a moving object in a video scene provided by Embodiment 1 of the present invention mainly includes the following steps:
[0020] Step 101, capturing a moving target.
[0021] The invention can be used to capture the moving target in the video stream captured by the camera in real time, and can also be used to capture the moving target in the video file.
[0022] The following is an example of how to capture a moving target by combining the inter-frame difference method and the background difference method.
[0023] First, frame data is extracted from video data (video stream or video file) and converted to RGB (tri-color) images. For example, for the DH-IPC-HF3101P bullet camera, use the data callback function (void CALLBACK DecCBFun(long nPort, char*pBuf, long nSize, FRAME_INFO*pFramelnfo, long nReserved1, long nReserved2) of its SDK (Software Development Kit) Extract frame data and convert the extracted frame data (YV...
Embodiment 2
[0047] figure 2 A schematic diagram of a system for detecting moving objects in a video scene provided by Embodiment 2 of the present invention, as shown in figure 2 As mentioned, the system mainly includes:
[0048] The moving target capture module 21 is used to detect the foreground pixels of the image using the inter-frame difference method and the background difference method, and fuse the results of both detections to obtain a foreground image that includes a moving target and its moving region;
[0049] The moving target tracking module 22 is used to extract a foreground block representing a certain moving target position in the foreground image, and track the foreground block until it leaves the video scene;
[0050] The moving object information generation module 23 is configured to generate summary information including the attributes and motion of the moving object corresponding to the foreground block according to the moving state of the moving object corresponding...
