Take the vehicle mentioned above as an example, the detected object is a vehicle that exists in the image acquiring scene after obtaining the detection zone. Therefore, when the coordinate of the vehicle (detected object) falls in the detection zone, the time of the vehicle stays in the detection zone exceeds the default time of the event rule, the moving direction of the vehicle in the detection zone does not meet the default direction of the event rule, or the speed of the vehicle moving in the detection zone falls outside of the default speed interval, the computing device then outputs the notification for the display device to display to notify the monitoring center that there may be abnormal activity in the image acquiring scene.

Please continue referring to step S08. However, when the computing device performs the event detection procedure in step S08 and determines the behavior of the detected object does not meet the event rule, step S01 can also be performed to obtain multiple images by the camera that are associated with the image acquiring scene; and when the behavior of the detected object meets the event rule, output the notification by the computing device for the display device to display.

In view of the above description, according to one or more embodiments of the method of acquiring detection zone in image of the present disclosure, an effective detection zone can be obtained based on the moving traces of the object. In addition, the detection zone doesn't need to be manually circled when cameras are set up in a new monitoring site, in turn saves the time of manually obtaining the detection zone.
