Abstract

The invention provides a hand position marking method and apparatus. The method comprises the steps of obtaining a to-be-identified image, wherein the to-be-identified image at least comprises a handshape; and according to the to-be-identified image and a pre-built hand position identification model, determining a hand position and a hand skeleton key point position in the to-be-identified image.According to the hand position marking method and apparatus provided by the invention, the hand position identification accuracy can be improved and the identification process is not influenced by environmental factors.

Description

technical field [0001] The invention relates to the technical field of machine vision object detection, in particular to a hand position identification method and device. Background technique [0002] With the expansion of the scale of urban rail transit, ensuring the standard operation of drivers is an important factor in maintaining operational safety. However, due to the complexity and uncertainty of driver behavior, the monitoring system that can monitor the driver's operation in real time and remind when violations are immature. Therefore, in order to realize driver behavior monitoring, one of the core technologies is the driver's hand position identification algorithm. [0003] At present, in the field of transportation, hand position identification technology is basically used for car drivers, such as the detection of the state of car drivers leaving the steering wheel with both hands, and the behavior analysis of answering the phone while driving. Due to the recogn...
