Method, device and equipment for determining palm area in gesture recognition

Abstract

The invention relates to a method for determining the palm area in gesture recognition, comprising the following steps: extracting the maximum contour of the gesture image within a set range; obtaining the average point of the depression points; using an erosion method to process the area of ​​the maximum contour multiple times , making the ratio of the area of ​​the processed contour to the area of ​​the largest contour a set ratio; weighting each pixel of the processed contour to obtain a first average point; judging the first average point and the depression Whether the Euler distance of the average point of the point is less than the set threshold, if so, obtain the gesture contour; otherwise, delete the average point of the sunken point and the pixel on the side of the midline of the first average point on the maximum contour, and calculate again first average point and repeat the above steps. The present invention also relates to a device for implementing the above method and a gesture recognition device. Implementing the method, device and equipment for determining the palm area in gesture recognition of the present invention has the following beneficial effects: the algorithm is simple, the cost is small, and the position error is small.

Description

technical field [0001] The present invention relates to the field of intelligent control, and more specifically, relates to a method, device and equipment for determining a palm area in gesture recognition. Background technique [0002] In the field of intelligent control, gesture recognition is an important control method. Usually, within the visual range of a smart device with visual functions, the user makes gestures with specific shapes and preset corresponding operations. When the device recognizes these gestures and finds the corresponding operations, it can automatically perform corresponding operation. In this process, to carry out the setting operation, the gesture must be recognized, and the basis for recognizing the gesture is to determine the area of ​​the palm, and recognize the gesture in this area. Generally speaking, gesture recognition is performed by judging the contour shape of the palm area. In the prior art, the gesture contour is obtained by obtainin...
