Evaluation of Motion Standard Based on Kinect Human Bone and Joint Data Acquisition

Abstract

In order to improve human bone and joint data, we propose a method to collect data and judge the standard of motion. Kinect is a 3D somatosensory camera released by Microsoft. It has three cameras in total. The middle is a color camera, which can take color images and obtain 30 images per second; on the left is the infrared projector, which irradiates the object to form speckle. On the right is the depth camera to analyze the infrared spectrum. On both sides are two depth sensors to detect the relative position of people. On both sides of Kinect are a set of quaternion linear microphone arrays for speech recognition and filtering background noise, which can locate the sound source. There is also a base with built-in motor below, which can adjust the elevation angle. It can not only complete the collection of color images, but also measure the depth information of objects. The experimental results show that we use MSRAction3D data set and compare the same cross-validation method with other latest research methods in the figures. The highest recognition rate of this method (algorithm 10) is the second, and the lowest and average recognition rates are the highest. The improvement in the lowest recognition rate is obvious, which can show that this method has good recognition performance and better stability than other research methods. Kinect plays a relatively important role in the movement of human bone and joint data acquisition.

Design of human lower limb motion data acquisition system based on multi-sensor

“…Therefore, in view of the shortcomings of the above research, this paper designed a wearable human lower limb motion data acquisition system with small volume, lightweight, and low power consumption, which can effectively detect the Angle data of the hip joint, knee joint, and ankle joint. Compared with the existing human lower limb motion data, the effectiveness of this system was verified [2]. Based on Angle detection, plantar pressure information is collected.…”
