Creality Scan offers two camera exposure control modes: Automatic Exposure and Manual Exposure.
Laser Scanning
For laser line scanning, we recommend users manually adjust the laser brightness and camera exposure time for better scanning quality. The desired state is to have both the markers and laser lines bright enough but not over-exposed, as shown in the figure above.
Fig. Camera exposure and laser line brightness adjustment.
First, adjust the IR camera's exposure time so that the markers have sufficient brightness but are not overexposed. The areas marked in red in the IR image window indicate over-exposed regions.
Then, adjust the brightness of the laser line so that it has sufficient brightness but does not overexpose.
NIR scanning
For relatively large targets, such as human face and body, Auto-Exposure can be used for scanning.
For smaller objects, automatic exposure may not be accurate. It is recommended to manually adjust the exposure time of the IR camera.
