Palm key point recognition method and device, terminal and readable storage medium

Abstract

The invention discloses a palm key point recognition method. The method comprises the steps of substituting the heat Tn of a feature point, a local convolution sub-network output result Ln of the feature point, a kernel function K, a global convolution sub-network output result Gn of the feature point and a preset weight omega into a loss function to calculate to obtain a loss function value; adjusting the weight of the neural network model according to the loss function value and the target output value until the loss function value meets a preset end condition to obtain a target neural network model; and obtaining a target palm image, inputting the target palm image into the target neural network model, and identifying a corresponding palm key point. The present invention also provides a palm key point recognition device, a terminal and a readable storage medium. According to the technical scheme, the palm key points are identified based on the neural network, the identification accuracy of the palm key points of the target neural network model can be improved, and the processing steps can be reduced.

Description

technical field [0001] The present invention relates to the technical field of image recognition, and in particular, to a method, device, terminal and readable storage medium for identifying key points of a palm. Background technique [0002] Image deformation, illumination, etc. will affect the accuracy of palm key point recognition. The accuracy of commonly used local convolutional neural networks (such as FRCNN network) to identify palm key points is related to the resolution of the image itself, and it needs to be recognized before key points are identified. Using other deep learning methods to obtain the range of the palm, the processing steps are cumbersome, and the accuracy of the recognition method is not high. [0003] Therefore, the existing methods for identifying key points of the palm have complicated processing steps and low accuracy, which is a problem to be solved urgently. SUMMARY OF THE INVENTION [0004] The main purpose of the present invention is to p...
