Title
(EN) Key point detection method and device, electronic equipment and storage medium
(ZH) 关键点检测方法、装置、电子设备及存储介质
Abstract
(EN)
The invention relates to a key point detection method and device, electronic equipment and a storage medium, and aims to solve the problem that the hand key point detection accuracy is low. The methodcomprises the steps of obtaining a to-be-detected gesture image, and dividing the gesture image into a plurality of regions; For each preset hand key point, determining the probability of occurrenceof the hand key point in each area and a first coordinate value in each area; And calculating a second coordinate value of the gesture key point in the gesture image through the probability and the first coordinate value. The method can adapt to the diversity of gestures, and the hand key point detection accuracy can be greatly improved.
