Embodiment Construction
[0026] In order to make the objects, technical solutions, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings. Based on the embodiments of the present invention, those of ordinary skill in the art will belong to the scope of the present invention in the scope of the present invention without making creative labor premises.
[0027] In one possible implementation, in order to solve a long time people watch the image information resulting from the monitoring events to determine the wrong question, you can monitor whether the event occurred using the machine image recognition method. Specifically, identification can be directed to a machine frame image captured by the monitoring camera is analyzed, thereby determining whether the frame image is red light in the event a pedestrian.
[0028] However, the predetermined event may be the occurrence of the target object is composed of a continu...

An embodiment of the present invention provides a method and device for monitoring event occurrence, wherein the method includes: after acquiring video information obtained by shooting a target object within a first preset time period, obtaining M frames of images according to the video information, and obtaining M frames of images according to the target object The position information of the object in each frame of image determines whether the target object has a preset event in each frame of image, and then determines whether the target object has a preset event according to the number of images in which the target object has a preset event in the M frames of images. Embodiments of the present invention provide a method for analyzing whether a monitoring event occurs based on video information. By dividing the video information into M frames of images, the number of images in which a preset event occurs on a target object can be used to determine whether a preset event occurs on a target object. Compared with the prior art method of determining whether a monitoring event occurs by analyzing a single frame of image, the method for monitoring event occurrence provided by the embodiments of the present invention is more accurate.
Description
Technical field [0001] The present invention relates to image processing technology, and particularly relates to a method and apparatus for monitoring events. Background technique [0002] Stage, with the development of artificial intelligence, many occasions to be monitored can be mounted with surveillance cameras, monitoring information by analyzing an image captured by the camera (including video or image), based on a case where a time period monitored has occurred default events. To monitor whether pedestrians running red lights, for example, by installing surveillance cameras at traffic lights, traffic information can view the images captured by surveillance cameras in the image information, if the direction of travel of the pedestrian is still in the red pedestrians through the intersection, then traffic police can determine a pedestrian red light running incidents occur. However, monitoring by means of artificial viewing image information events usually take a long time, a...
