Abstract
Provided is a disclosure for detection of objects using projected light of one or more frequencies, where the light may be structured or non-structured.
Claims23
A system for detecting an object, comprising:
- a substantially collimated scanning light source configured to output source light;
- a first camera configured to receive first reflected light, wherein the first reflected light is the source light reflected from the object to the first camera, the first reflected light having a first intensity that is a function of distance to and reflectivity of the object relative to the first camera;
- a second camera configured to receive second reflected light, wherein the second reflected light is the source light reflected from the object to the second camera, and the second camera is separated in space from the first camera, the second reflected light having a second intensity that is a function of distance to and reflectivity of the object relative to the second camera;
- and
- one or more processors configured to:
- control the scanning light source, the first camera, and the second camera;
- and
- concurrently process both the first reflected light and the second reflected light at least in part by comparing the first and second intensities to detect the object and to determine one or more of:
- distance to the object, a color intensity of the object, and a color accuracy of the object.

A method for detecting an object, comprising:
- outputting source light by a substantially collimated scanning light source;
- receiving first reflected light by a first camera, wherein the first reflected light is the source light reflected from the object to the first camera, the first reflected light having a first intensity that is a function of distance to and reflectivity of the object relative to the first camera;
- receiving second reflected light by a second camera, wherein the second reflected light is the source light reflected from the object to the second camera, and the second camera is separated in space from the first camera, the second reflected light having a second intensity that is a function of distance to and reflectivity of the object relative to the second camera;
- controlling, by one or more processors, the scanning light source, the first camera, and the second camera;
- and
- concurrently processing both of the first reflected light and the second reflected light at least in part by comparing the first and second intensities to detect the object and to determine one or more of:
- distance to the object, a color intensity of the object, and a color accuracy of the object.
4 more elements
A system for detecting an object, comprising:
- a scanning light source configured to output a source light, wherein the scanning light source comprises at least two discrete lights that are substantially collimated;
- a first camera configured to receive first reflected light with a rolling shutter camera process, wherein the first reflected light is the source light reflected from the object to the first camera;
- a second camera configured to receive second reflected light with the rolling shutter camera process, wherein the second reflected light is the source light reflected from the object to the second camera, and the second camera is separated in space from the first camera;
- and
- one or more processors configured to:
- control the scanning light source, the first camera, and the second camera;
- and
- process both the first reflected light and the second reflected light a row of pixels at a time to detect the object and to determine one or more of:
- depth to the object, a color intensity of the object, and a color accuracy of the object.
