摘要
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.
