Problems solved by technology

[0004] Although the above-mentioned educational toy kit solves the problem of lack of interactivity in games on the tablet computer, due to the large base plate, the position of the jigsaw puzzle often deviates, resulting in the camera not being able to capture a complete image, and the image is prone to errors. Analysis results Problems such as inaccuracy appear, and it is impossible to detect the shape of the jigsaw puzzle, nor can it judge the color of the jigsaw puzzle, and it is impossible to analyze whether the splicing pattern of the jigsaw puzzle is accurate

Embodiment 2

[0089] Figure 5 is a flowchart of a method for recognizing colors of jigsaw puzzles in an educational toy kit.

[0090] Such as Figure 5 Shown, a kind of jigsaw puzzle color recognition method in the educational toy kit, comprises the steps:

[0091] Step 1, install the game program in the tablet computer, install the bottom end of the tablet computer in the second groove, install the helmet detector on the top of the tablet computer through the fourth groove, and then place the jigsaw puzzle on the bottom plate;

[0092] Step 2. After the installation is fixed, collect images through the front camera of the tablet computer. The specific steps are:

[0093] First, define the image captured by the front camera of the tablet as I xy , I xy =f(x,y);

[0094] Wherein, (x, y) represents the position coordinates of the image pixel point, and f(x, y) represents the pixel value of the image on (x, y);

[0095] Since the image collected by the camera is a color picture, f(x, y)...

Abstract

The invention relates to the technical field of computer visual inspection processing and provides an educational toy set and a tangram color recognition method thereof. The educational toy set is characterized in that a support is mounted on a baseplate, a helmet detector is mounted on the support, a first groove is formed in the baseplate, a protrusion is formed at the bottom of the support and mounted in the first groove, a second groove and a third groove are formed at the top of the support, the helmet detector is mounted in the third groove, and the educational toy set further comprises a positioning hole. The tangram color recognition method includes: mounting a tablet computer installed with a game program on the educational toy set, and placing tangram on the baseplate; collecting images through the tablet computer; performing perspective conversion on the images; calculating side length and ration between angle and side length of edge profile of each piece of the tangram, acquiring color value in HSV images, and judging color of each piece of the tangram. By using the method, shape and size of each piece of the tangram can be detected quickly, color can be analyzed in the HSV images, and then color of each piece of the tangram can be recognized by combining shape, size and color of each piece of the tangram.

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 jigsaw puzzle 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 the base pl...
