Problems solved by technology

[0006] The embodiment of the present invention provides a method and device for intelligent recognition of baby's sleeping posture, aiming to solve the problem of lack of monitoring and recognition of baby's sleeping posture in the existing baby monitoring system, so that the baby cannot be kicked off the quilt, and the baby's face is covered by clothes Timely detection of important baby events such as babies sleeping on their stomachs can easily cause the baby to catch cold or suffocate

Embodiment approach

[0069] S16. Perform SIFT feature analysis on the sample matting. The specific steps are: find extreme points in the scale space, extract the position, scale, and rotation invariants. The implementation method is as follows:

[0070] ●Generation of scale space

[0071] The purpose of the scale space theory is to simulate the multi-scale characteristics of image data, and use the Gaussian convolution kernel to realize the scale transformation of the space. The scale space of the sample image is defined as:

[0072] L(x,y,σ)=G(x,yσ)*I(x,y) (6)

[0073] where G(x, y, σ) is a scale-variable Gaussian function.

[0074] G ( x , y , σ ) = 1 2 πσ 2 e - ( x 2 ...

Abstract

The invention discloses an intelligent identification method and device for a baby sleep position. A video analysis and mode identification method is adopted to identify the baby sleep position so as to timely discover important baby events like a baby kicks out a quilt, the face of the baby is covered by clothes, or the baby sleeps on the stomach. The method consists of three parts, namely sample feature modeling, real-time feature analysis and alarm judgment. In the sample feature modeling, textural features and SIFT (Scale Invariant Feature Transform) features of a sample image are analyzed, a sample feature template base is generated by means of feature fusion, furthermore, the features of a set monitoring area are analyzed while the real-time features are analyzed, the sleep position is identified in combination with the sample feature template base, the alarm type is judged, and then the alarm information is output. Due to the intelligent identification method and device, a guardian does not have to monitor the baby all the time by videos or observation on site, especially when the guardian sleeps soundly at night, the important baby events can be effectively and intelligently detected, identified and warned early and timely.

Description

technical field [0001] The invention relates to the field of baby monitoring, in particular to a method and device for intelligent recognition of a baby's sleeping posture. Background technique [0002] Parents pay more and more attention to baby safety monitoring. Baby sleeping posture monitoring is an important part of baby safety monitoring. However, current baby monitoring systems lack intelligent analysis and recognition of baby sleeping posture, which may easily cause important baby events to not be discovered in time. The existing baby monitoring system is mainly realized through two types of technologies: the first type is through video monitoring, which uses a camera to monitor the baby in real time, and the guardian can watch the baby's situation through the display terminal. The defect of this type of system technology is that the guardian needs to take the initiative Pay attention to the display terminal, often can not deal with the baby event in time, especially...
