Magic cube color identification method based on artificial neural network

Abstract

The invention discloses a magic cube color identification method based on an artificial neural network. The method includes steps: establishing an artificial neural network training model; acquiring pictures of surfaces of a magic cube, marking color blocks along contours of the color clocks of the magic cube on the pictures by employing rectangular marking frames, marking color categories of thecolor blocks according to category numbers, storing coordinates of upper left corners and lower right corners of the rectangular marking frames and the corresponding category numbers in marking filescorresponding to the pictures; training the artificial neural network training model by employing the marking files and a data set formed by the corresponding pictures, and forming a network model file stored in a mobile platform; and during identification, acquiring pictures of surfaces of a to-be-processed magic cube according to the sequence by employing a camera by the mobile platform, retrieving the network model file for identification to identify a determination picture of the surface at each time of acquisition of the picture of one surface, outputting a color number group of the surface, and finally forming two-dimensional color rectangular output to complete identification. According to the method, the identification rate in a complex environment is increased by introduction of amagic cube robot color identification algorithm into the neural network.

Description

technical field [0001] The invention relates to the technical field of robot image recognition, in particular to a Rubik's Cube color recognition method based on an artificial neural network. Background technique [0002] The Rubik's Cube is a changeable intellectual toy, also known as Rubik's cube, invented in 1974 by Professor Rubik of the Budapest School of Architecture in Hungary. Because of its infinite mystery, there are a large number of fans, and there are extensive and in-depth research on the Rubik's Cube in the academic circles, and the research results of the Rubik's Cube have also been used in many applications. [0003] The Rubik's Cube robot acquires, processes and recognizes the Rubik's Cube image based on image analysis and computer vision, and conducts a comprehensive analysis and management of the Rubik's Cube information, and automatically restores any disrupted Rubik's Cube. [0004] Some Rubik's Cube restoration robots have higher environmental require...

Problems solved by technology

The HSV color space is another commonly used color space. It is established based on the characteristics of human psychological perception. It belongs to the polar coordinate space structure. Its advantage is that it can describe the color intuitively. , when the light changes and the value of a certain component in the light is slightly higher, many errors will occur in the color classification

Therefore, it is not suitable for the classification and quantification of colors
