Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0021] The present invention provides a data filtering method:

[0022] Add a filter to smooth the data and correct the coordinates of the bone points. The filter part first applies the spike removal filter, the spike removal filter is the name of a filter, which can filter out the spike-shaped signal in the signal to make the signal smooth; when the bone coordinates of adjacent frames change more than a certain threshold When thresh1, the present invention takes thresh1=0.05 as an example, and uses the bone coordinate smoothing value S of the previous frame n-1 and the current frame bone coordinate X n The weighted as the output of the filter When the weight of the first current frame α (...

Abstract

The invention relates to a data filtering method. Through a series of formulas, the weighted average of original data with predication value is obtained so that a filtering purpose is achieved. The invention also provides a precise location method for coordinates of skeleton points. By obtaining a basis of reference, movable coordinates of skeleton points are obtained so that the skeleton points are precisely located.

Description

technical field [0001] The invention relates to a bone point correction method, in particular to a data filtering method and a precise positioning method of bone point coordinates. Background technique [0002] With the development of human-computer interaction technology, simple mouse and keyboard as input devices have been difficult to meet people's needs. The natural human-computer interaction technology based on the human body itself and voice has been developed. In recent years, an image and audio acquisition platform—Kinect—has appeared on the market. It can not only provide color images provided by traditional color cameras, but also output depth images, and further provide human bone images on the basis of depth images. However, due to the defects of the technology itself, when there is self-occlusion, the bone points will shake and fluctuate, and the bone points on the arm will move when the palm changes from opening to fisting. Affects the control effect when usi...
