Method for detecting blocking state of image acquisition device, electronic device and storage medium

An electronic device, comprising:

• a processor;
• and
• a memory, configured to store a computer program that, when executed by the processor, causes the processor to perform the following operations including:
• obtaining an image acquired by an image acquisition device;
• and
• determining, according to the acquired image, whether the image acquisition device is in a blocked state, the determining comprises:
• determining average brightness of the acquired image according to the acquired image;
• in response to the average brightness of the acquired image is greater than or equal to a first brightness threshold and is less than or equal to a second brightness threshold, the first brightness threshold being less than the second brightness threshold, determining a ratio of a foreground area to an effective area of the acquired image, wherein the foreground area represents an area of a foreground portion of an image recognized from the acquired image, and the effective area is predetermined and is less than or equal to an area of the acquired image;
• in response to the ratio of the foreground area to the effective area of the acquired image is less than or equal to a set value, determining a number of outlines in the acquired image, wherein the number of outlines is a number of target outlines obtained by performing outline detection on the acquired image;
• in response to a duration in which the number of outlines in the acquired image is less than a set number, the duration being greater than or equal to a first set duration, determining that the image acquisition device is in the blocked state, and
• in response to the number of outlines in the acquired image being greater than or equal to the set number, determining that the image acquisition device is in an unblocked state.

A non-transitory computer-readable storage medium, having stored thereon a computer program that, when executed by a processor, causes the processor to perform a method for detecting a blocking state of an image acquisition device, the method comprising:

• obtaining an image acquired by an image acquisition device;
• and
• determining, according to the acquired image, whether the image acquisition device is in a blocked state, the determining comprises:
• determining average brightness of the acquired image according to the acquired image;
• in response to the average brightness of the acquired image is greater than or equal to a first brightness threshold and is less than or equal to a second brightness threshold, the first brightness threshold being less than the second brightness threshold, determining a ratio of a foreground area to an effective area of the acquired image, wherein the foreground area represents an area of a foreground portion of an image recognized from the acquired image, and the effective area is predetermined and is less than or equal to an area of the acquired image;
• in response to the ratio of the foreground area to the effective area of the acquired image is less than or equal to a set value, determining a number of outlines in the acquired image, wherein the number of outlines is a number of target outlines obtained by performing outline detection on the acquired image;
• in response to a duration in which the number of outlines in the acquired image is less than a set number, the duration being greater than or equal to a first set duration, determining that the image acquisition device is in the blocked state, and
• in response to the number of outlines in the acquired image being greater than or equal to the set number, determining that the image acquisition device is in an unblocked state.
