AI Technical Summary

Problems solved by technology

[0003] However, the fingertip algorithm based on geodesic distance is limited by the gesture position when detecting the fingertip, and cannot detect the fingertip when the finger is facing the camera
The coordinate algorithm based on geometric features has the defects of slow calculation speed and poor calculation effect
These problems affect the accuracy and efficiency of fingertip detection and positioning, and make fingertip detection less robust in practical applications

Abstract

Disclosed are a fingertip detection method, a fingertip detection device, fingertip detection equipment and a medium. Wherein the fingertip detection method comprises: based on the depth image, determining the minimum depth point (N) in the hand area to be detected; based on the depth image, determining the hand vertex (T) in the hand area to be detected; based on the minimum depth Point (N) and the hand vertex (T) determine the fingertip position. Based on the hand vertex (T) and the minimum depth point (N), the fingertip detection can be realized accurately and efficiently when the user adopts different gestures.

Description

technical field [0001] The present disclosure relates to the field of touch technology, and more specifically, to a fingertip detection method, a fingertip detection device, a fingertip detection device and a medium. Background technique [0002] With the continuous development of virtual touch in civil and commercial fields, fingertip detection and positioning, as a key technology of virtual measurement and control, is also facing higher requirements. For the detection and location of the fingertip, the fingertip algorithm based on geodesic distance and the coordinate algorithm based on geometric features can be used. [0003] However, the fingertip algorithm based on geodesic distance is limited by the gesture position when detecting the fingertip, and the fingertip cannot be detected when the finger is facing the camera. The coordinate algorithm based on geometric features has the defects of slow calculation speed and poor calculation effect. These problems affect the a...
