Teaching toy kit and number identification method

Abstract

The invention relates to the field of computer vision detecting and processing technology, and provides a teaching toy kit and a number identification method thereof. The teaching toy kit comprises a bracket, a helmet detector and a bottom cushion. The upper part of the bottom cushion is provided with two control recessed troughs for placing control buttons, and the lower part is provided with number recessed troughs for placing number cards of 1, ...,9, wherein the number cards have multiple colors. The helmet detector is mounted on the bracket. The helmet detector further comprises a body, a third recessed trough, two fan-shaped blocks and a convex mirror. Furthermore the third recessed trough is arranged in the body. The convex mirror is arranged at an end point of a panel computer screen which is held by the third recessed trough. The other end of the convex mirror is mounted on the edge of the helmet detector. An included angle between the convex mirror and the horizontal surface is an acute angle. The two fan-shaped blocks are arranged on two edges of the convex mirror. According to the teaching toy kit, the position of the bottom cushion can be quickly corrected based on the contour information of the bottom cushion, and furthermore whether the number cards placed in the recessed troughs at the lower part of the bottom cushion are correctly placed. The teaching toy kit and the number identification method have advantages of improving interest and interactive property, and furthermore improving accuracy of image acquisition results and image analysis results.

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 a digital 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and looking at the screen for a long time is likely to cause damage to the eyes; Traditional game toys have outdated the development of the times, and cannot meet children's learning and playing needs in form, and are not convenient for children and parents to interact and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, a kind of educational toy kit has been successfully developed in the field of computer vision and image processing technology, including: a bracket, a helmet detector, a bottom pad, and a game program is installed in a tablet computer,...
