Laser galvanometer image distortion correction : SLA and engraving
Image Color PickerThis website will help collect values about the pixels of the photo. Scan several of the laser path sections to determine a lower bound BGR value to test.
If the results of this test detect too many laser nodes, then the BGR values for the lower bound are too low. Too few, then the lower limit is too high.
The high bound of the BGR laser path should almost always be 255 for all channels.
For the printed circle values, check the BGR values for all of the circles.
If this is your first time getting the BGR threshold, please walk throught with the tutorial below.
BGR TutorialNote on website: It gives RGB values not BGR, so note the difference when inputting the values.
