Problems solved by technology

Generally speaking, the above measuring instruments and measuring methods have obvious deficiencies in application, mainly reflected in the low measurement efficiency, time-consuming and laborious, and poor operability. Even the compass measuring instrument cannot simultaneously realize the precise synchronization of multiple indicators of cervical spine mobility. Measurement; more critically, the above methods have poor repeatability and reliability in measuring the range of motion of the cervical spine, and are very susceptible to measurement errors caused by the influence of the measured personnel or operators, which cannot meet the clinical application needs of doctors.

Embodiment Construction

[0035] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0036] According to the height of the testees, the Kinect sensor was placed horizontally on a 1.5m high measuring platform, so that it was at the same level as the face, 1.5m away from the human body, and the Kinect sensor was powered, and the USB interface of the Kinect sensor was inserted into the computer.

[0037] A method for measuring the range of motion of the cervical spine based on the Kinect sensor, comprising the following steps:

[0038] 1), use the Kinect sensor to acquire and transmit depth data and color data in its field of view, such as figure 1 Shown:

[0039] 1.1), the Kinect sensor emits laser speckle into the Kinect field of view through its own infrared emitter, records the laser speckle pattern in the space through its own CMOS infrared camera, combines the original speckle pattern, and calculates the spatial depth in the field...

Abstract

The invention discloses a method for measuring a cervical vertebra motion degree on the basis of a Kinect sensor. The method comprises the following steps of acquiring and delivering depth data and color data in a vision field of the Kinect sensor by utilization of the Kinect sensor, then extracting three-dimensional coordinates of human face feature points and bone joint points, constructing a head feature vector and a body feature vector, calculating a cervical vertebra motion angle, then displaying the cervical vertebra motion angle, and finally recording the measured data. The method disclosed by the invention has the advantages that the human cervical vertebra motion degree can be quickly, precisely and remotely measured, and the effects of high efficiency, simplicity in operation and high reliability are achieve.

Description

technical field [0001] The invention relates to the technical field of medical information intelligent processing, in particular to a method for measuring the range of motion of the cervical spine based on a Kinect sensor. Background technique [0002] In medicine, changes in the range of motion of the cervical spine are of great significance to reflecting the function of the cervical spine. There are generally two methods for measuring the range of motion of the cervical spine, one is to measure the overall range of motion of the cervical spine, and the other is to measure a single vertebral body flexion and extension activities. In the clinical sense, measuring the range of motion of a single vertebra has more medical guiding significance, but in clinical practice, the measurement of intervertebral joints is time-consuming, laborious, and complicated to operate, while the measurement of the overall range of motion of the cervical spine is relatively simple. The measuremen...
