Problems solved by technology
[0004] When the user is in a prone position, the motion state is generally a small movement, such as the stretching of the legs or the rotation of the head. It is impossible to adjust its own working state according to the user's prone position, resulting in poor rationality for smart home appliances to adjust their own working state

[0126] In one embodiment of the present invention, when the space coordinate system is established, the specific implementation of step 103 may include:
[0127] determining the position coordinates of the endpoints of the endpoints of each effective fragmented block in the space coordinate system;
[0128] According to the position coordinates of each of the endpoints, determine the minimum endpoint with the smallest x-axis coordinate and y-axis coordinate and the maximum endpoint with the largest x-axis coordinate and y-axis coordinate from each endpoint;
[0129] According to the minimum endpoint and the maximum endpoint, determine the integrated rectangular area corresponding to each effective broken tile; wherein, the diagonal endpoints of the integrated rectangular area are the minimum endpoint and the maximum endpoint, and the integrated rectangular area The length and width are respectively parallel to the x-axis and y-axis of the space coordinate system;

The present invention provides a human body prone position state identification method and device. The method comprises the steps of: continuously collecting at least two images to be identified in anarea to be identified; A1: comparing a current frame with a previous frame, and determining at least one motion broken graph block in the current frame, wherein each motion broken graph block is different from the color and / or the gray level of the corresponding image block in the previous frame; A2: when the number of the at least one motion broken graph block is larger than a quantity thresholdvalue, performing integration of each motion broken graph block to determine one dynamic area of the current frame; A3: determining whether the current frame is the last frame or not, if yes, executing A4, or else, taking the next frame of the current frame as the current frame, and executing the A1; and A4: according to each dynamic area, determining a human body prone position dynamic area in the area to be identified. The human body prone position state identification method and device achieves identification of the motion state when the user is in a prone position state and improves reasonability of regulating the work state of a smart home itself.
Description
technical field [0001] The invention relates to the technical field of image processing, in particular to a method and device for recognizing a human body's lying posture state. Background technique [0002] With the development of science and technology and the improvement of people's living standards, people's requirements for smart home appliances are getting higher and higher. There are many smart home appliances with human body recognition function, which can automatically adjust their working status according to the user's exercise status. [0003] According to the posture of the user, the user state can be divided into a standing posture (standing, sitting and squatting) state and a lying posture (supine, prone and side lying) state. When the user is in a standing posture, its motion state is generally relatively large-scale motion, such as a change in the user's position. Existing smart home appliances mainly identify the movement state of the user when the user is...
