Abstract
An example system in accordance with aspects of the present disclosure includes a controller and a camera communicatively coupled to the controller to capture an image of a work surface. A projector is also provided and is coupled to the controller to project an illumination pattern onto the work surface during image capture by the camera.
Claims20
A projection capture system, comprising:
- a controller;
- a camera communicatively coupled to the controller to capture an image of an object on a work surface;
- and
- a projector communicatively coupled to the controller to project a non-uniform correction illumination pattern onto the work surface during image capture of an object by the camera.
1 more element
A projection capture system, comprising:
- a controller;
- a projector communicatively coupled to the controller;
- and
- a camera communicatively coupled to the controller to capture an image of an object on a work surface;
- wherein the controller is to perform a calibration cycle in which the controller is to determine that no object is present on a work surface, cause the camera to capture an image of the blank work surface using a uniform light source generated by the projector, and generate a non-uniform correction illumination pattern based at least in part on the captured image of the blank work surface.
2 more elements
A method, comprising:
- retrieving a non-uniform correction illumination pattern from a storage device;
- projecting said non-uniform correction illumination pattern;
- and
- capturing an image of an object while projecting said non-uniform correction illumination pattern.
