Abstract:
1. A method for controlling playing of monitoring video record, comprising the following steps: A. during the process of recording a monitoring video record, detecting a picture of a video record in real time and marking a time index for dynamic frame(s) in the video record; and B. during the process of playing the monitoring video record, obtaining the time index and playing the dynamic frame in the monitoring video record according to the time index; wherein in the Step A, the step of detecting the picture of the video record in real time and marking the time index for the dynamic frames in the video record is carried out in the following way: A1. beginning the recording of the monitoring video record, setting a start time flag and a minimum video record mark time period with the start time flag set as true, and marking a moment at which the recording begins as a start time point of a current dynamic frame; A2. detecting the picture of the video record; A3. judging whether there is a moving object in the picture of the video record and whether the start time flag is true, and performing one of the following operations according to a result of the judgment: 1) when there is a moving object in the picture of the video record and the start time flag is true, the next step is executed; 2) when there is a moving object in the picture of the video record and the start time flag is false, the start time flag is set as true, the current moment of the video record is marked as the start time point of the current dynamic frame, and the next step is executed; 3) when there is no moving object in the picture of the video record and the start time flag is true, it is judged whether the time difference between the current moment of the video record and the start time point previously recorded is larger than the minimum video record mark time period, wherein if the result of the judgment is yes, the start time flag is set as false, the current moment of the video record is marked as the end time point of the current dynamic frame, and the next step is executed; and otherwise, the next step is executed; 4) when there is no moving object in the picture of the video record and the start time flag is false, the next step is executed; A4. judging whether the recording of the monitoring video record is finished, wherein if yes, the next step is performed; otherwise, it returns to the Step A2; and A5. judging whether the start time flag is true, wherein if yes, the start time flag is set as false, and the current moment of the video record is marked as the end time point of the current dynamic frame.
