The True Color Production Workflow used to process raw imagery into true color orthophotos, output as true color results for one or multiple independent scenes. It is suitable for scenarios where color differences between multiple scenes are not a concern, and the primary requirements are accurate geolocation and clear, natural visual appearance.

• Set Image Path: Specify the processing paths for raw imagery, reference imagery, and result data. Supports filtering and pairing of raw panchromatic and multispectral images.
• Generate Tie Points: Automatically generates tie points in overlapping image areas for mosaicking and block adjustment of multiple satellite images, ensuring geometric consistency among them.
• Generate Ground Control Points: Generates Ground Control Points based on image feature points for high-precision geometric correction and geolocation, ensuring the geographic positional accuracy of the imagery.
• Block Adjustment: Calculates the orientation parameters of the satellite images through adjustment computation based on the tie points and ground control points.
• Generate Orthophotos: Orthorectifies the imagery to remove geometric distortions caused by terrain relief and sensor attitude, producing a panchromatic orthophoto.
• Multispectral and Panchromatic Registration: Registers the multispectral imagery to the corrected panchromatic image, ensuring precise spatial alignment between the panchromatic and multispectral data.
• Image Fusion: Performs pan-sharpening (or other fusion techniques) to combine the panchromatic and multispectral images, enhancing image quality by integrating their respective spatial and spectral details.
• True Color Output: Applies image stretching and enhancement techniques to improve the visual display effect, making the colors closer to the actual ground object colors.
