Dynamic motion detection method and apparatus, and storage medium

An electronic device, comprising:

• a processor;
• and
• a memory configured to store processor-executable instructions;
• wherein the processor is configured to invoke the instructions stored in the memory, so as to:
• add an image frame in a video stream into a first queue with a length which is the minimum number of the image frames for dynamic action detection, to obtain the first queue of partially updated image frames, the number of added image frame being less than the length of the first queue;
• detect a dynamic action in the first queue of partially updated image frames;
• determining that the dynamic action does not match with an action detection result, the action detection result comprising a previously detected action detection result;
• and
• update the action detection result according to the dynamic action in response to the determination that the dynamic action does not match with the action detection result,
• wherein the action detection result comprises a static action, and adding the image frame in the video stream into the first queue, to obtain the first queue of partially updated image frames comprises:
• obtaining a static action in an image frame to be identified in the video stream;
• determining that that the static action in the image frame to be identified does not match with the static action in the action detection result;
• and
• adding the image frame to be identified into the first queue in response to the determination that the static action in the image frame to be identified does not match with the static action in the action detection result, to obtain the first queue of partially updated image frames.

A non-transitory computer readable storage medium, having computer program instructions stored thereon, wherein when the computer program instructions are executed by a processor, the processor is caused to perform the operations of:

• adding an image frame in a video stream into a first queue with a length which is the minimum number of the image frames for dynamic action detection, to obtain the first queue of partially updated image frames, the number of added image frame being less than the length of the first queue:
• detecting a dynamic action in the first queue of partially updated image frames:
• determining that the dynamic action does not match with an action detection result, the action detection result comprising a previously detected action detection result, the action detection result comprising a previously detected action detection result;
• and
• updating the action detection result according to the dynamic action in response to the determination that the dynamic action does not match with the action detection result,
• wherein the action detection result comprises a static action, and adding the image frame in the video stream into the first queue, to obtain the first queue of partially updated image frames comprises:
• obtaining a static action in an image frame to be identified in the video stream;
• determining that that the static action in the image frame to be identified does not match with the static action in the action detection result;
• and
• adding the image frame to be identified into the first queue in response to the determination that the static action in the image frame to be identified does not match with the static action in the action detection result, to obtain the first queue of partially updated image frames.

The non-transitory computer readable storage medium of 16, wherein the previously detected action detection result is obtained by performing operations comprising:

• determining that a dynamic action exists in the image frame of the first queue;
• moving the image frame in the first queue into a second queue in response to the determination that a dynamic action exists in the image frame of the first queue;
• and
• determining the action detection result according to an image frame in the second queue.

The non-transitory computer readable storage medium of 16, wherein the action detection result further comprises an action trajectory of the static action and/or switching information between static actions;

• and wherein adding the image frame in the video stream into the first queue, to obtain the first queue of partially updated image frames comprises:
• determining that the static action in the image frame to be identified matches with the static action in the action detection result;
• determining the action trajectory of the static action and/or switching information between the static action in the image frame to be identified according to the image frame to be identified and the image frame in the second queue in response to the determination that the static action in the image frame to be identified matches with the static action in the action detection result;
• determining that that the action trajectory of the static action and/or switching information between the static actions in the image frame to be identified does not match with the action detection result;
• and
• adding the image frame to be identified into the first queue in response to the determination that the action trajectory of the static action and/or switching information between the static actions in the image frame to be identified does not match with the action detection result, to obtain the first queue of partially updated image frames.
