Embodiment 1

[0098] figure 1 It is a flowchart of a gait analysis method provided by an embodiment of the present application. see figure 1 , the method is implemented based on the walking video of the analysis object, including:

[0099] Step 101, acquiring the gait parameters of the analysis object in the walking video.

[0100] Step 102: Evaluate the physical condition of the analysis object according to the gait parameters.

[0101] The gait analysis method provided in this embodiment, after the method acquires the gait parameters of the walking video of the analysis object, the physical condition of the analysis object is analyzed according to the gait parameters, and the physical condition of the analysis object can be directly evaluated after obtaining the gait parameters ; Using video images instead of a large number of sensors for evaluation reduces costs and shortens the analysis cycle, thereby increasing the application range and application frequency of gait analysis.

Embodiment 2

[0103] Based on the above embodiments, the embodiment of the present invention provides another embodiment of a gait analysis method, combining figure 2 , the method includes:

[0104] Step 201, obtaining the gait parameters of the analysis object in the walking video, specifically including:

[0105] 1) Identify the characteristic parts of the analysis object from each frame of video image.

[0106] In this step, first obtain a walking video of the analysis object, and use the deep learning algorithm to automatically identify the characteristic parts of the analysis object. Among them, the walking video is a video of a single person walking, and the video can be a frontal walking video or a sideways walking video. For the automatic identification and analysis of the characteristic parts of the object using the deep learning algorithm, there have been detailed descriptions, so I won’t go into details here .

[0107] Among them, the characteristic parts are designated parts...

Embodiment 3

[0128] image 3 It is a schematic structural diagram of a gait analysis device provided by an embodiment of the present application. refer to image 3 , the embodiment of the present application provides a gait analysis device, including:

[0129] A processor 301, and a memory 302 connected to the processor;

[0130] The memory is used to store a computer program, and the computer program is used to implement the gait analysis method described in Embodiment 1 and Embodiment 2;

[0131] The processor is used to call and execute the computer program in the memory;

[0132] For the specific implementation scheme of the computer program in this embodiment, please refer to the relevant descriptions in the embodiments of the gait analysis method described in the foregoing Embodiments 1 and 2, and will not be repeated here.

Abstract

The invention relates to a gait analysis method and a device, which relate to the field of medical technology and solve the problems of high cost, long cycle and high professional requirement of the prior method. The method is realized based on walking video of an analysis object. According to gait parameters to evaluate the physical condition of the analysis object, the method is mainly used forhuman gait analysis.

Description

technical field [0001] The present application relates to the field of medical technology, in particular to a gait analysis method and device. Background technique [0002] Studies by international authoritative medical institutions have shown that there is a clear correlation between abnormal human gait characteristics and cognitive dysfunction. Recording, tracking, and analyzing the gait changes of the human body are of great social significance for the early detection of diseases related to cognitive dysfunction. [0003] Gait analysis is the main means of medical diagnosis and rehabilitation evaluation, and runs through the entire process of rehabilitation medicine. In related technologies, the analysis of human gait often relies on large-scale professional medical equipment, which requires a large number of sensors, which is not only costly , long period, and high professional ability are required, which limit the application range and application frequency of gait ana...
