Embodiment Construction

[0013] Gait evaluation methods mainly include physical examination and scale scoring, mostly qualitative or semi-quantitative evaluations, such as observing and describing the gait characteristics of the subject in the walking test, recording the time and number of steps completed for the test, or if according to the balance Each scoring item of the subject is scored in detail one by one by using the Posture Assessment Scale and Posture Assessment Scale. The accuracy of these evaluation methods all depend on the subjective clinical experience and knowledge level of the evaluating doctor, lack of certain norms, large individual differences among different evaluators, and poor repeatability.

[0014] Now, there are some different gait assessment methods, such as wearable devices and 3D gait analysis, which are gradually applied to clinical gait quantitative analysis. By fixing sensors on each limb, or building sensors into insoles, or integrating hundreds of thousands of barorec...

Abstract

The invention discloses a gait detection method. The method comprises the following steps: setting an image acquisition device, wherein a detected person completes standing and walking actions according to detection requirements; acquiring gait videos of the detected person through the image acquisition device, wherein the gait videos comprise RGB videos and depth videos, and the depth videos obtain distance parameters according to color block differences; and inputting the gait videos into a trained gait detection model, and making a gait detection conclusion of the detected person by the gait detection model.

Description

technical field [0001] The invention belongs to the technical field of human health assessment, and in particular relates to a gait detection method, system and equipment. Background technique [0002] With the intensification of the aging society, gait disorders and cognitive dysfunction seriously threaten the health of the elderly, resulting in the decline of the daily life ability of the elderly and the increase of the disability rate, which brings a heavy medical burden to the society and the family. According to literature reports, in China, falls due to gait disturbance are the fourth cause of injury-related death, and the first cause of death among the elderly over 65 years old. The fall mortality rate of the elderly over 65 years old was 49.56 / 100,000 for men and 52.80 / 100,000 for women. In the United States, 30% of people over the age of 65 suffer at least one fall each year, and this proportion exceeds 50% of people over the age of 80. Gait disorders have multipl...
