Problems solved by technology

[0003] However, in the color image of the human hand, the key points may be occluded. In this case, the position of the key point in the color image of the human hand may present an image of an obstacle, which may lead to , the probability that the calculated position is the position of the key point is low, and there is a large deviation from the actual situation
As a result, the three-dimensional space position of the key point cannot be calculated, or the accuracy of the calculated three-dimensional space position is low, which affects the attitude estimation of the human hand

Abstract

The invention relates to a key point position determining method and device and electronic equipment. The method comprises the following steps: determining the shape of a human hand and poses of a plurality of skeleton nodes in the human hand based on an image to be analyzed including the image of the human hand; and on the basis of the shape and the pose, determining the positions of the key points of the hand according to a preset geometric constraint condition of the skeleton of the hand. According to the method, the position of the shielded key point can be accurately calculated by utilizing the geometric constraint condition of the hand bone of the hand in combination with the hand parameters extracted from the to-be-analyzed image.

Description

technical field [0001] The present disclosure relates to the technical field of hand pose estimation, and in particular to a method, device and electronic equipment for determining key point positions. Background technique [0002] In related technologies, the posture of the human hand can be estimated by using the three-dimensional space positions of multiple key points of the human hand. For each key point, the probability that each pixel in the hand color image is the key point can be calculated based on the hand color image (such as an RGB image), and the probability distribution of the key point on the two-dimensional image can be obtained, and based on the probability distribution, using the pre-trained neural network to calculate the three-dimensional space position of the key point. [0003] However, in the color image of the human hand, the key points may be occluded. In this case, the position of the key point in the color image of the human hand may present an im...
