Substep S151: and establishing a coordinate system in the image formed by each graph and acquiring coordinate information of preset points in the graph.
The number of the preset points can be one or more. The position of the preset point may be a point at any position in the graph, or may be a corner point of the graph. In this embodiment, the preset points are corner points of the graph, and the number of the preset points is the same as the number of the corner points. The relative coordinate information of each preset point in the graph can be obtained by establishing a coordinate system.
Substep S152: and judging whether the position relation between the graphs is adjacent or not according to the coordinate information of the preset points in the graphs.
specifically, the relative position relationship of the graph corresponding to the corner point is obtained by obtaining the corner point of the graph and calculating according to the relative position of the corner point, for example: vectors can be obtained according to the coordinates of the corner points in different graphs, and whether the position relation is adjacent or not can be obtained through calculation.

the preset condition is a straight line satisfying a corner relationship, for example: when the figures formed by the intersecting straight lines are triangles, whether the relation of the corners of an equilateral triangle or an isosceles right triangle is met or not is judged; and when the formed graph is a quadrangle, whether the corner relation of the square, the parallelogram or the rhombus is met or not is judged.
Substep S158: removing the areas filled with multiple colors results in a pattern filled with a single color.
Substep S159: the colour of the puzzle corresponding to the figure is obtained from the figure filled with a single colour.
The shape and the color of each chocolate plate in the image and the corresponding position of each chocolate plate can be obtained through the setting.
Step S160: and judging whether the image formed by the identified tangram with each color and shape is matched with preset information or not to obtain a judgment result.
The preset information is various, each preset information comprises a preset position relation and preset color information of the corresponding graph of each chocolate plate, and the step of judging whether the image formed by the identified chocolate plates with various colors and shapes is matched with the preset information comprises the following steps: and judging whether the relative position relation of the chocolate plates is matched with the preset position relation or not, and judging whether the color information of the chocolate plates at the corresponding positions is matched with the preset color information or not.
specifically, the method is realized by detecting a figure in an image formed by the tangram, acquiring the color corresponding to the detected figure and the angular points arranged according to the sequence of the hour, and mapping the color information in the preset information and the angular point information arranged according to the sequence of the hour. And secondly, judging whether the adjacent chocolate plates of the detected figures correspond to the adjacent chocolate plates of the mapping figures or not, and if so, marking the adjacent chocolate plates as the detected figures. And thirdly, repeating the step two until all the graphs of the image formed by the chocolate plate are detected, and obtaining a detection result.
since there are many unstable factors that may affect the photographed image in the process of acquiring the image formed by each of the chocolate plates by the image acquisition device 30, the unstable factors may be lighting environments such as day, night, strong light or weak light, or shadows of surrounding objects on the image formed by each of the chocolate plates or shadows of human shadows on the image, and these factors may affect the image formed by each of the chocolate plates acquired by the image acquisition device 30, the image acquisition device 30 needs to perform denoising processing after acquiring the image formed by each of the chocolate plates. In this embodiment, optionally, the chocolate plate identification method further comprises step S130.
step S130: and filtering the image formed by the skillets to eliminate noise interference.
in this embodiment, the image formed by the respective chocolate plates may be denoised by Gamma correction and histogram equalization, where Gamma correction is to normalize the color space of the input image to adjust the contrast of the image, reduce the influence of local shadows and illumination changes in the image, and suppress noise interference. Histogram equalization is to widen the gray levels with a large number of pixels in an image and compress the gray levels with a small number of pixels in the image, thereby expanding the dynamic range of the original value of the image, improving the contrast and increasing the change level of the gray levels to make the image clearer. By processing the images using the two methods, the quality of the image formed by each of the chocolate plates is better.
On the basis of the above method, the display device 40 can display different difficulty levels of the puzzle pattern when playing the puzzle game, for example: any puzzle pattern at any one of the three levels of easy, medium and difficult play. The display device 40 displays the colour, shape, location of each puzzle when performing easy stratification. The display device 40 displays the shape of a partial region when performing a middle hierarchy. The display device 40 displays only the shape of the entire pattern when performing difficult levels, and masks the color and shape of each board. In addition, when the puzzle game is played, the display device 40 may not display any image, and the user may splice the images as desired. In the process of splicing the puzzle game by a user, the image acquisition device 30 acquires images formed by splicing the puzzle pieces at preset intervals, and the processor 20 receives the images formed by the puzzle pieces, identifies and judges the images. If the image of each of the chocolate pieces being laid out already corresponds to the configuration of a local area of the chocolate pattern in the preset message, the processor 20 controls the display device 40 to display a game interface and to flash a reminder at the appropriate area for the correct layout. When it is detected that all of the images of the puzzle pieces have been properly and fully laid out, the processor 20 controls the display device 40 to indicate the end of the game, thereby enabling real-time interaction.
Through the setting, the user can experience the fun of real-time interaction in the game process and the thinking exercise brought by different difficulty when playing the puzzle game, so that the interest of the puzzle game is effectively improved, and the user is guided to exert imagination.
