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 method and device for recognizing the state of a human prone posture. The method includes: continuously collecting at least two frames of images to be recognized in the region to be recognized; A1: comparing the current frame with the previous frame to determine the At least one motion fragment; Wherein, the color and / or grayscale of each motion fragment is different from the corresponding image block in the previous frame; A2: When the number of at least one motion fragment is greater than the number threshold, Integrate each moving broken block to determine the dynamic area of the current frame; A3: determine whether the current frame is the last frame, if so, perform A4, otherwise, use the next frame of the current frame as the current frame Frame execution A1; A4: According to each dynamic area, determine the dynamic area of human prone posture in the area to be identified. This solution realizes the recognition of the motion state of the user when the user is in the prone state, and improves the rationality of the smart home appliance to adjust its own working state.
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...
