At present, the premise of gait analysis is that animals need to perform continuous movement on a specific track. This forced movement for animals will cause them to deviate from the original movement law, and the resulting gait parameters are divorced from the real situation. The application value limited

Abstract

The embodiment of the invention discloses a gait analysis method and device, equipment and a storage medium. The method comprises the steps of acquiring limb images of a to-be-analyzed object located on a static plane at all moments; for the limb image at each moment, determining a three-dimensional skeleton of the to-be-analyzed object at each moment according to the limb image at each moment; determining a gait generation moment when the to-be-analyzed object generates a gait from the moments according to the three-dimensional skeletons, and taking the three-dimensional skeleton at the gait generation moment as a target skeleton; and determining gait parameters of the to-be-analyzed object according to each target skeleton. According to the technical scheme provided by the embodiment of the invention, the gait parameters of the to-be-analyzed object in the free moving state can be accurately obtained.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of image processing, and in particular to a gait analysis method, device, equipment and storage medium. Background technique [0002] Gait analysis can provide automated, fast, objective and complete results of gait-related changes following a medical condition or acute pain. At present, the premise of gait analysis is that animals need to perform continuous movement on a specific track. For animals, this forced movement will cause them to deviate from the original movement law, and the resulting gait parameters are divorced from the real situation. The application value limited. Contents of the invention [0003] Embodiments of the present invention provide a gait analysis method, device, equipment, and storage medium, so as to realize the effect of gait analysis on an object to be analyzed in a freely moving state. [0004] In the first aspect, the embodiment of the present in...
