Embodiment 1
[0072] figure 1 It is a schematic flowchart of a method for obtaining a color card code provided in Embodiment 1 of the present invention. The method can be executed by a device for obtaining a color card code, wherein the device can be implemented by software and / or hardware. like figure 1 As shown, the method includes:
[0073] Step 101, obtaining the original image of the color card, and performing denoising processing on the original image according to a preset denoising algorithm to obtain a processed original image;
[0074] Specifically, the original image of the color card is obtained through the camera on the drone, and the corresponding denoising process is performed on the obtained original image, the specific method is as follows:
[0075] Correspondingly, performing denoising processing on the original image according to a preset denoising algorithm to obtain a processed original image, including:
[0076] Carrying out the first color space conversion on the or...
Embodiment 2
[0107] image 3 It is a schematic flowchart of a method for obtaining a color card code provided in Embodiment 2 of the present invention, which is optimized on the basis of Embodiment 1. like image 3 As shown, the method includes:
[0108] Step 301, acquiring the original image of the color card, and performing denoising processing on the original image according to a preset denoising algorithm to obtain a processed original image;
[0109] Step 302, acquiring the information of the processed original image, the information including color information and the area ratio corresponding to each color;
[0110] Step 303, acquiring the generation rule of the color card, the generation rule including preset at least one color area, the color of each color area and the area ratio between each color area;
[0111] Correspondingly, the acquisition of the generation rule of the color card includes:
[0112] The color card includes four color areas, the color of the four color area...
Embodiment 3
[0125] Figure 4 It is a schematic flowchart of a method for obtaining a color card code provided in Embodiment 3 of the present invention, which is optimized on the basis of Embodiment 1. like Figure 4 As shown, the method includes:
[0126] Step 401, obtaining the original image of the color card, and performing denoising processing on the original image according to a preset denoising algorithm to obtain a processed original image;
[0127] Step 402, acquiring the information of the processed original image, the information including color information and the area ratio corresponding to each color;
[0128] Step 403, if the area ratio is within the preset area ratio threshold, obtain the coding information of each color, and obtain the coding of the color card according to the coding information of each color;
[0129] Step 404, according to the correspondence between the coded information and the coordinates, obtain the coordinates corresponding to the coded informatio...
