[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 through the fourth groove;
[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 o...

Abstract
The invention relates to the technical field of computer visual detection processing and provides an educational toy set and a positioning hole detecting and positioning method thereof. The educational toy set comprises a support, a helmet detector and a baseplate, the support is mounted on the baseplate, the helmet detector is mounted on the support, a first groove is formed above the baseplate, the bottom of the support is provided with a protrusion which is mounted in the first groove while the top of the same is provided with a second groove and a third groove, the second groove is used for containing a tablet computer, and the helmet detector is mounted in the third groove. The educational toy set is characterized in that a positioning hole is formed in the bottom side of the side wall of the third groove and positioned on a longitudinal central axis of the side wall. The method includes: mounting the tablet computer and the helmet detector; collecting an image through a prepositive camera of the tablet computer; processing the image to acquire a position image of the positioning hole; judging whether the tablet computer is mounted accurately or not according to position of the positioning hole. The positioning hole is formed in the educational toy set, mounting accuracy and speed are improved, and higher accuracy in image collection and analysis result is realized.
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...
