Hand gesture detection method involves acquiring initial depth image using backbone and apparatus, and non-transitory computer-readable storage medium

Abstract

Provided are a hand gesture detection method and device, and a computer storage medium. The method includes: obtaining an initial depth image including a hand to be detected, and performing detection processing on the initial depth image by using a backbone feature extractor and a bounding box detection model to obtain initial bounding boxes and a first feature map corresponding to the hand to be detected; determining one of the initial bounding boxes as a target bounding box; cropping, based on the target bounding box, the first feature map by using RoIAlign feature extractor, to obtain a second feature map corresponding to the hand to be detected; and performing, based on the second feature map, a three-dimensional gesture estimation processing on the hand to be detected by using a gesture estimation model to obtain a gesture detection result of the hand to be detected.
