What if the picture taken by the panoramic camera has chromatic aberration?

Before shooting, set the appropriate white balance mode according to the light conditions of the shooting environment. If there is a custom white balance function, white cards or gray cards can be used for calibration to ensure that pictures from different angles have consistent color performance under the same light conditions.

For example, when shooting in the sun, select the sunlight white balance mode; When shooting under indoor light, select the corresponding light white balance mode, such as incandescent light or fluorescent light mode.

Ensure that all parameters of the panoramic camera are consistent during shooting, including ISO, shutter speed, aperture, etc. The change of these parameters will affect the color and brightness of the picture, and inconsistent parameters may cause color difference.

For example, set the panoramic camera to manual mode, and shoot after fixing various parameters to avoid automatic adjustment of parameters in automatic mode.

Try to avoid multiple different types of light sources at the same time in the shooting scene, such as sunlight and indoor light mixing, light mixing of different colors, etc. Mixing light sources will lead to inconsistent color of pictures from different angles, increasing the possibility of color difference.

If you cannot avoid mixing light sources, you can try to use shading equipment or adjust the shooting angle to reduce the impact of different light sources on the picture.

Ensure that the panoramic camera is stable during shooting and avoid shaking or vibration. Unstable shooting may cause color changes, especially in long exposure or low light environment.

Use a tripod or stabilizer to fix the panoramic camera to ensure the stability of the equipment during shooting.

Select professional panoramic image mosaic and processing software, which usually has powerful color adjustment function and can effectively solve the color difference problem. For example, PTGui, Autopano Giga and other software.

In the software, you can adjust the color of the panoramic image as a whole, including adjusting the color temperature, hue, saturation and other parameters, so that the color of the picture from different angles is more uniform.

Manually adjust the part with color difference through the color adjustment tool in the software. You can select specific areas and use tools such as color balance and curve adjustment to correct color deviation.

For example, if the picture from one angle is blue, but the picture from other angles is normal, you can select the blue area in the software, reduce the value of the blue channel, and increase the value of the yellow channel to achieve the effect of color balance.

Select some reference points with relatively stable colors in the panoramic image, such as white walls, gray floors, etc., and use these reference points as the standard for color calibration.

By adjusting the color parameters in the software, make the colors of these reference points in the pictures from different angles as consistent as possible, so as to achieve the color unification of the overall picture.
