Working Principle
2. PRODUCT INTRODUCTION
1. Unique inside-out monocular positioning technology, keep third camera
tracking the targets wall when scanning workpiece.
2. Laser lines projected onto the object deforms with the shape of the object.
When scanning, the camera takes the specific shape and calculates it.
Tips:
The indicator red dot should project on the targets wall.
The visibility of laser lines projected on the workpiece is a key to success of
data acquisition.
The visibility of laser lines is affected by color and material type.
High reflectivity workpiece will have mirror effect, which makes it difficult to
catch laser lines.
Black color absorbs light and makes laser lines difficult to detect laser
lines.
The effects of black, reflective and transparent objects can be offset by
adjusting shutter parameters.
Good preparation in advance will lead to satisfying scanning results.
