Abstract

Embodiments of the invention provide a sample data generation method and device and electronic equipment. When sample data used for training a deep learning model is constructed, a hand kinematics model can be constructed, and the hand kinematics model is used for describing the influence of a hand posture and a hand skeleton length on the position of a hand key point, generating a plurality of groups of sample data according to hand posture information of a standard gesture predefined by a user and the hand kinematics model; Through the method, a large amount of sample data can be quickly and conveniently obtained, a user does not need to manually label hand key points, the sample data obtaining difficulty is reduced, the constructed sample data can be more diversified and higher in accuracy, and therefore the prediction precision of the trained deep learning model can be improved.

Description

technical field [0001] This specification relates to the field of artificial intelligence technology, and in particular to a method, device and electronic equipment for generating sample data. Background technique [0002] Gesture recognition has a wide range of applications in many fields, for example, smart devices can be controlled through gestures. Accurate recognition of user gestures is the prerequisite for gesture control. At present, when recognizing user gestures, the 2D position information or 3D position information of the key points of the hand can be obtained from the RGB image or depth image containing the hand, and then the 2D or 3D position information into a pre-trained deep learning model to predict hand poses in images. When training the deep learning model in this way, it is cumbersome to label the key points of the hand and the gesture of the hand in the image, and the sample data constructed is limited, which will affect the prediction accuracy of the ...
