Abstract
Embodiments herein relate to identifying whether a threshold amount of material is on a surface. In particular, an apparatus may have an inspection module to receive an image of a surface captured by a camera, where the surface is illuminated by a light source positioned at an angle to the surface. The apparatus may then analyze the received image to identify a measurement of light intensity of one or more portions of the surface; and determine, based on the analysis, whether each of the one or more portions of the surface includes a threshold amount of a material on the surface.
Claims25
An apparatus comprising:
- one or more processors;
- an inspection module communicatively coupled to the one or more processors to:
- receive an image of a surface captured by a camera, wherein the surface is illuminated by a light source positioned at an angle to the surface;
- analyze the received image to identify a measurement of light intensity of one or more portions of the surface;
- and
- determine, based on the analysis, whether each of the one or more portions of the surface includes a threshold amount of a material on the surface.
A method comprising:
- receiving an image of a surface captured by a camera, wherein the surface is illuminated by a light source positioned at an angle to the surface;
- analyzing the received image to identify a measurement of light intensity of one or more portions of the surface;
- and
- determining, based on the analysis, whether each of the one or more portions of the surface includes a threshold amount of a material on the surface.
One or more computer-readable media comprising instructions that cause a computing device, in response to execution of the instructions by the computing device, to:
- receive an image of a surface captured by a camera, wherein the surface is illuminated by a light source positioned at an angle to the surface;
- analyze the received image to identify a measurement of light intensity of one or more portions of the surface;
- and
- determine, based on the analysis, whether each of the one or more portions of the surface includes a threshold amount of a material on the surface.
An system comprising:
- one or more processors;
- an inspection module communicatively coupled to the one or more processors to:
- receive an image of a surface captured by a camera, wherein the surface is illuminated by a light source positioned at an angle to the surface;
- analyze the received image to identify a measurement of light intensity of one or more portions of the surface;
- and
- determine, based on the analysis, whether each of the one or more portions of the surface includes a threshold amount of a material on the surface;
- and
- the camera communicatively coupled to the one or more processors.
