Embodiment 1

[0083] According to the relevant data reference of "Chinese Adult Human Dimensions" (GB / T 10000-1988) and the principle of Kinect skeleton node setting, the central node of the head can be approximately regarded as the center of the C1 vertebral body of the cervical spine, and the central node of the shoulder can be approximately regarded as the thoracic vertebral body The center of the T1 vertebral body and the central node of the sacrum are approximately regarded as the center of the S vertebral body of the sacrum. These three nodes divide the spine into cervical, thoracic, and lumbar segments.

[0084] Taking the estimation of the lumbar vertebral body as an example, Kinect can be used to obtain the central node of the shoulder (vertebra T1 vertebral body center) and the sacral central node (sacrum S vertebral body center). Knowing these two points, the center points of the lumbar vertebral bodies L1 to L5 can be derived.

[0085] The hardware of this method mainly compris...

Abstract

The invention discloses a real-time in-vivo measuring method for right and left lateral flexion of thoracic and lumbar vertebrae based on Kinect somatosensory interaction technology with the purpose of realizing posture determination and speculation during the motion process of lateral flexion of thoracic and lumbar vertebrae and outputting coordinates of center nodes of all centrums. During measurement, a somatosensory man-machine interaction mode is adopted and a Kinect sensor is utilized for real-time capture of postures and motion of a human torso. In combination with multi-body system kinemics, positions and postures of all centrums of a vertebral column are calculated in order to real-time acquisition of coordinates of center nodes of all centrums and posture angles. Operation is performed easily and conveniently. The postures of the vertebral column and the center nodes of all centrums are displayed on an interactive interface of a system in a real-time mode.

Description

technical field [0001] The invention relates to a measurement method, in particular to a real-time in-body measurement method for left and right scoliosis of thoracolumbar spine. Background technique [0002] Spinal movement is a three-dimensional movement, which is the most complex among the joint movements of the human body. Understanding the range of motion of the patient's spine is of great significance for guiding doctors in spinal physical therapy and rehabilitation. [0003] At present, there are many difficulties in the study of spinal kinematics, because the motion of the spine is a coupled motion in three-dimensional space rather than a specific plane motion, which requires precise measurement techniques and calculation methods. The three-dimensional motion of the spine has three degrees of freedom: flexion / extension, left / right bending and left / right rotation. The invention is specially used for measuring the lateral bending motion in the left and right directio...
