Image Correction

## Image Correction

This module requires the Image Calibration module to be performed first, and then import the image through this module for correction.

## Usage Scenarios
Situations where distortion correction is required.

## Module Principle

## Usage Method

### Predecessor/Successor Modules
After performing distortion correction calibration, you can directly input the image and reference the calibration for correction.

【Calibration Group】 Select the corresponding coordinate system group, and the calibration data will be recorded in the calibration file under the coordinate system group. The coordinate system group must be set in the coordinate system calibration in the global data management.
【Input Image】When the input image size is different from the image size during calibration, it may affect the correction result.
## Output Description
Output is the corrected image.
