Abstract
The invention provides an educational toy set and an HSV based color identification method for a Rubik's cube, and relates to the fields of detecting and processing technologies of computer vision. The educational toy set comprises a support, a base plate, a helmet detector and a positioning hole, wherein the support is mounted on the base plate, the helmet detector is mounted on the support, and the base plate is provided with a first groove; the bottom of the support includes a projection which is mounted in the groove; the top of the support includes second and third grooves; and the helmet detector is mounted in the third groove. A tablet computer provided with a game program is mounted on the educational toy set, and the Rubik's cube is placed on the base plate; the tablet computer collects images; rim shapes of colored color blocks of the Rubik's cube are detected in the image; the amount of ovals is used to determine whether the Rubik's cube is placed in the correct position; influence of ambient light on the image color is removed to obtain an original scene image; and the tone value of the original scene image in an HSV color space is calculated to determine the color of each color block. According to the method, whether the Rubik's cube is placed in the correct position and the colors of the color blocks of the Rubik's cube can be determined rapidly.
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 an HSV-based Rubik's Cube color recognition method thereof. 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and looking at the screen for a long time is likely to cause damage to the eyes; Traditional game toys have outdated the development of the times, and cannot meet children's learning and playing needs in form, and are not convenient for children and parents to interact and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 installed on t...
