The application belongs to the technical field of glove mold, and relates to a glove mold and a preparation method of the glove mold. The glove mold comprises a main body and a thumb part, both of which are made of stainless steel. The main body has a palm part, and the palm part is provided with an index finger part, a middle finger part, a ring finger part and a little finger part. The thumb part is fixed between the palm part by welding, and is arranged in a curved manner. The preparation method of the glove mold comprises the following steps: S1, injecting the main body and the thumb part of the glove mold by stainless steel liquid injection molding; and S2, welding the thumb part of the glove mold on the palm part of the main body to form the glove mold. The application can improve the product quality of the glove mold with curved fingers.

A gesture recognition method based on geometric characteristics is a method for recognizing gestures according to the number of fingers and the finger direction angle, comprising the steps of: collecting a hand image by using a camera; searching for the skin color and binarizing the hand; removing the palm from the hand based on mathematical morphological erosion; obtaining the palm contour based on a contour search method; calculating the palm contour centroid and bottom center based on a moment; calculating the hand detection curve based on a trigonometric function; detecting the number of fingers based on the hand detection curve; calculating the finger direction angle based on a vector method; and recognizing gestures by combining the number of fingers and the finger direction angle. The present application can accurately, timely and stably recognize gestures, can recognize gestures of left and right tilting, forward and backward tilting and slightly curved fingers, and can recognize up to sixteen kinds of gestures.

The utility model relates to the field of agricultural machinery, in particular to a star wheel mechanism. The star wheel mechanism provided by the utility model mainly comprises a star wheel integrated part, the shifting rod is arranged on the star wheel integrated part, the shape of the shifting rod is set to be in a bent finger shape, and when the star wheel integrated part drives the shifting rod to rotate, plant clusters are shifted in a grabbing mode. According to the star wheel mechanism provided by the invention, the operation part (the driving lever) is improved to be bent, and the head part is conical, so that the function of driving corns in a hand grabbing manner is realized, and the corns can be effectively prevented from being damaged.
