Abstract
A system includes an illumination source, a camera arranged to detect illumination from the illumination source, and a computer communicatively coupled to the illumination source and the camera. The computer is programmed to detect an object in image data from the camera, identify landmarks of the object in the image data, determine a distance from the camera to the object based on a pixel distance between the landmarks in the image data, and adjust a brightness of the illumination source based on the distance.
Claims21
A system comprising:
- an illumination source;
- a camera arranged to detect illumination from the illumination source;
- and
- a computer communicatively coupled to the illumination source and the camera;
- wherein the computer is programmed to:
- detect an object in image data from the camera;
- identify landmarks of the object in the image data;
- determine a distance from the camera to the object based on a pixel distance between the landmarks in the image data;
- adjust a brightness of the illumination source based on the distance;
- and
- after adjusting the brightness of the illumination source and receiving new image data, perform object recognition on the new image data of the object to recognize the object as a recognized specific individual object.
A computer comprising a processor and a memory storing instructions executable by the processor to:
- detect an object in image data from a camera;
- identify landmarks of the object in the image data;
- determine a distance from the camera to the object based on a pixel distance between the landmarks in the image data;
- adjust a brightness of an illumination source based on the distance, the illumination source arranged to produce illumination detectable by the camera;
- and
- after adjusting the brightness of the illumination source and receiving new image data, perform object recognition on the new image data of the object to recognize the object as a recognized specific individual object.
(canceled)
A method comprising:
- detecting an object in image data from a camera;
