An educational toy kit and its method for detecting and locating Rubik's cube based on shape matching

Abstract

In the technical field of computer visual detection processing, an educational toy kit and magic cube location detection method therefor based on shape matching are provided, comprising a bracket (1) installed on a bottom plate (3) and a detector helmet (2) installed on the bracket (1), a first groove (301) being provided on the bottom plate (3); the bottom of the bracket (1) has a projection (101), said projection (101) being installed in the first groove (301), and the top of the bracket having a second and a third groove (102, 103); the detector helmet (2) is installed in the third groove (103); the kit further comprises a positioning hole (104), provided on the third groove (103), located at the vertical central axis of the side wall. A game program is installed on a tablet computer; the tablet computer is placed on the educational toy kit, and a magic cube is placed on the bottom plate (3); images are captured by means of the tablet computer; the round shapes of the color blocks of the magic cube are detected in the images; whether placement of the magic cube on the bottom plate (3) is correct is determined by the number of ovals detected. The present means of detecting the location of a magic cube can rapidly judge whether the placement of the magic cube is correct, improving accuracy of image capture and analysis.

Description

technical field [0001] The invention relates to the technical field of computer vision detection and processing, in particular to an educational toy kit and its shape-matching-based Rubik's Cube detection and positioning method. Background technique [0002] Now there are many interesting preschool education game applications or children’s games on tablet PCs, but they often just let children finger and draw on the screen, which lacks interactivity, and looking at the screen for a long time is likely to cause damage to the eyes; Traditional game toys have outdated the development of the times, and cannot meet children's learning and playing needs in form, and are not convenient for children and parents to interact and communicate. [0003] In order to solve the above problems, an educational toy kit has been successfully developed in the field of computer vision recognition processing technology, including: a bracket, a helmet detector and a base plate, and the bracket is in...

Problems solved by technology

[0004] Although the above-mentioned educational toy kit solves the problem of lack of interaction in games on tablet computers, due to the large base plate, the position of the Rubik’s Cube often deviates, resulting in the camera not being able to capture a complete image, and the image is prone to errors. The emergence of problems such as inaccuracy
