Embodiment 1

[0064] figure 1 It is a structural schematic diagram of an educational toy kit of the utility model.

[0065] figure 2 It is the rear view of the bracket of an educational toy kit of the utility model.

[0066] image 3 It is a perspective view of a bracket of an educational toy kit of the utility model.

[0067] Figure 4 It is a structural schematic diagram of the bottom plate of an educational toy kit of the utility model.

[0068] Such as Figure 1-4 As shown, an educational toy kit includes a bracket 1, a helmet detector 2 and a base plate 3, and the bracket 1 is installed on the base plate 3, and the helmet detector 2 is installed on the bracket 1; the base plate 3 is provided with a first groove above 301: The bracket 1 has a protrusion 101 at the bottom, and the protrusion 101 is installed in the first groove 301, and the top of the bracket has a second groove 102 and a third groove 103, and the second groove 102 is used to place a tablet computer; The helmet d...

Embodiment 2

[0076] Figure 5 It is a flow chart of an educational toy kit and a positioning hole detection and positioning method thereof.

[0077] Such as Figure 5 Shown, a kind of educational toy kit and positioning hole detection positioning method thereof, comprises the following steps:

[0078] Step 1, first install the bottom end of the tablet computer in the second groove, and then install the helmet detector on the top of the tablet computer;

[0079] Step 2, after the installation is fixed, collect images through the front camera of the tablet computer;

[0080] Define the image captured by the front camera of the tablet as I xy , I xy =f(x,y);

[0081] 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);

[0082] Since the image collected by the camera is a color picture, f(x, y)=(R xy , G xy , B xy );

[0083] Among them, R xy Indicates the color value of the image pixel in the r...

Abstract

An educational toy kit, and a method of detecting and positioning an alignment hole (104). The kit comprises a support frame (1), a detector helmet (2), and a base plate (3). The support frame (1) is mounted on the base plate (3), the detector helmet (2) is mounted on the support frame (1), and a first recess (301) is provided on an upper side of the base plate (3). A lower portion of the support frame (1) is provided with a protrusion (101) mounted in the first recess (301), and an upper portion thereof is provided with a second recess (102) and a third recess (103). The second recess (102) is used to place a tablet computer, and the detector helmet (2) is mounted in the third recess. The kit further comprises: an alignment hole (104) arranged at a bottom of a side wall of the third recess (103), and located on a vertical center axis of the side wall. The method comprises the following steps: securely mounting a tablet computer and the detector helmet (2); capturing an image by means of a front camera of the tablet computer; processing the image to obtain an image position of the alignment hole (104); and determining, according to the position of the alignment hole (104), whether the tablet computer is mounted correctly. Providing the alignment hole (104) on the educational toy kit improves the mounting precision and speed, and enables more accurate image capturing and analysis.

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 method for detecting and positioning a positioning hole 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 install...
