Abstract
The present disclosure relates to a system and method for calibrating an optical device, such as a camera. In one example, the system includes a light-emitting device that generates light patterns and an ray generator that is positioned between the light-emitting device and the optical device. The ray generator separates the light emitted as part of the light patterns into a plurality of directional rays. The optical device then captures the directional rays and the captured data, along with data corresponding to the light pattern and the ray generator, are used to calibrate the optical device.
Claims21
A system for calibrating an optical device comprising:
- a light ray generator for generating directional light rays in optical communication with the optical device, wherein
- the ray generator separates light to generate a plurality of directional light rays;
- and
- the directional light rays are captured by the optical device.
A method for calibrating an optical device comprising:
- generating by a light-generating device, a light pattern;
- separating by a ray generator the light pattern into a plurality of light rays;
- capturing one or more images by the optical device of the plurality of light rays;
- and
- determining by a processing element one or more lens properties of the optical device based on the light ray images captured by the optical device.
A calibration assembly for use in calibrating a camera, comprising:
- an emitting device that generates light wavelengths;
- and
- an optical mask in optical communication with the emitting device;
- wherein
- the optical mask separates the light wavelengths emitted from the emitting device into one or more directional light rays.
