Abstract
A scanning system performs a is a method of scanning a part. A light source illuminates a part with a light, and a gloss meter measures a surface reflectivity of the part based on a reflection of the light from the part. A processor determines a gloss unit for the part based on the surface reflectivity, adjusts an acquisition parameter and a processing parameter of the scanning system based on the gloss unit, and scans the part with the imaging device using the acquisition parameter to obtain an image and processes the image with the processing parameter to obtain a point cloud.
Claims20
A method of scanning a part, comprising:
- illuminating the part with a light from a light source of a scanning system, wherein the scanning system includes an imaging device;
- obtaining a reflection of the light reflected from the part;
- determining a gloss unit of the light reflected from the part;
- adjusting an acquisition parameter of the scanning system based on the gloss unit;
- and
- obtaining an image of the part at the imaging device using the acquisition parameter.
A scanning system, comprising:
- a light source for illuminating a part with a light;
- a gloss meter for measuring a surface reflectivity of the part based on a reflection of the light from the part;
- an imaging device;
- and
- a processor configured to:
- determine a gloss unit for the part based on the surface reflectivity;
- adjust an acquisition parameter of the scanning system based on the gloss unit;
- and
- scan the part with the imaging device using the acquisition parameter.
A method of scanning a part, comprising:
- illuminating the part with a light from a light source of a scanning system, wherein the scanning system includes an imaging device;
- obtaining a reflection of the light reflected from the part;
- determining, at a processor, a gloss unit of the light reflected from the part;
- adjusting, at the processor, an acquisition parameter and a processing parameter of the scanning system based on the gloss unit;
- and
- obtaining, at the processor, a point cloud from an image of the part obtained using the light source and the imaging device operating with the acquisition parameter and the processor operating with the processing parameter.
