Specifically, after the calibration scene is determined, the AR device acquires a sample image collected by the camera from the calibration scene for displaying the calibration.
A first marker in the sample image and a second marker in the calibration scene corresponding to the first marker are determined, step 106.
Specifically, after the calibration scene and the sample image are determined, the user is prompted to determine a first marker in the sample image and a second marker of the first marker in the calibration scene. Optionally, the number of the first markers and the positions of the markers in the sample image are not limited, and the number of the markers may be 1, 2, 3, or 4, etc.; the marker may be text, an article, etc.
And step 108, receiving an input adjusting instruction.
Specifically, the AR device displays a prompt message to prompt the user to observe whether the first marker in the displayed sample image can be overlapped with the second marker in the calibration scene, and inputs a corresponding adjustment instruction according to the overlapping condition of the first marker in the sample image and the second marker in the calibration scene. The adjusting instruction can be input on a human-computer interaction interface of the AR equipment and can also be generated through voice control; the adjustment instructions include, but are not limited to, position adjustment instructions and image adjustment instructions.
And 110, performing display calibration on the sample image according to the adjustment instruction until the first marker and the second marker coincide.
Specifically, according to the coincidence condition of a first marker in the sample image and a second marker in the calibration scene, a corresponding adjustment instruction is received and input, and according to the adjustment instruction, the first marker of the sample image displayed on the AR device is completely coincided with the second marker in the calibration scene. Alternatively, when the first marker in the sample image is a window on a wall, according to the adjustment instruction, until the boundary line between the window and the wall in the sample image displayed on the AR device completely coincides with the boundary line between the window and the wall in the calibration scene.

The AR device can identify the calibration scene through a built-in identification algorithm to obtain the RGB value of the calibration scene.
Step 310, color processing is performed on the sample image according to the color data of the calibration scene.
The color processing is to process the RGB values of the image, so that the RGB values of the processed image are different from the RGB values of the image before processing. The color processing may be a reverse color processing of the sample image by which the R, G, B value of the image is inverted, and the contrast of the image with the sample image may be increased. For example, if the quantization level of the color is 256, the R, G, B value of the image after the inversion process is 255 minus the R, G, B value of the original image.
