An educational toy kit and its number recognition method

Abstract

A teaching toy kit and a number identification method thereof. The teaching toy kit comprises a support (1), a helmet detector (2), and a base pad (3). The upper part of the base pad (3) is provided with two control recesses (301, 302) for placing control buttons, and the lower part is provided with number recesses (303) for placing number cards of 1 to 9 of multiple colors. The helmet detector (2) is mounted on the support (1) and further comprises a body (201), a third recess (202), two fan-shaped blocks (203), and a convex mirror (204). The third recess (202) is located in the body (201). The convex mirror (204) is provided at an end point, where the screen of a tablet computer is held, of the third recess (202), and the other end of the convex mirror (204) is mounted on an edge of the helmet detector (2). An angle between the convex mirror (204) and the horizontal plane is an acute angle. The two fan-shaped blocks (203) are provided on two edges of the convex mirror (204). According to the teaching toy kit and the number identification method thereof, the position of the base pad can be quickly corrected on the basis of contour information of the base pad, and it can be determined whether the number cards in the recesses at the lower part of the base pad are correctly placed, so that the teaching toy kit is funnier and more interactive, and accuracy of image acquisition and analysis is enhanced.

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 identification method thereof. Background technique [0002] Nowadays, there are many interesting preschool education game applications or children's games on tablet computers, but they often just let children point and draw on the screen, which lacks interactivity. Looking at the screen for a long time is easy to cause damage to the eyes; Traditional game toys have been out of touch with the development of the times, cannot meet the needs of children's learning and play 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 and image processing technology, which includes: a bracket, a helmet detector, a bottom pad, a game program is installed in th...

Problems solved by technology

Although the above-mentioned educational toy kit solves the problem of lack of interactivity in the game on the tablet computer, the position of the bottom pad will be deviated, which will cause the camera to fail to capture a complete image, which is prone to errors in image collection and inaccurate analysis results. the emergence of
