Claims14
An apparatus for determining 3D coordinates of an object, the apparatus comprising:
- a 3D sensor comprising:
- at least one camera and
- at least three plane projectors and
- a plurality of line-scan sensors that are arranged at an angle with respect to one another.
An apparatus for determining 3D coordinates of an object, the apparatus comprising:
- a 3D sensor comprising:
- a camera and
- a plurality of plane projectors that extend perpendicularly with respect to one another, wherein each of the plurality of plane projectors is configured to project a light plane and,
- a plurality of line-scan sensors that are arranged at an angle with respect to one another.
A method for determining 3D coordinates of an object using an apparatus including a 3D sensor and a plurality of line-scan sensors that are arranged at an angle with respect to one another, wherein the 3D sensor includes at least one camera and at least three plane projectors that project light planes, the method comprising:
- recording the object using the at least one camera,
- determining points of intersection of the light planes using the line-scan sensors, and
- determining, from the points of intersection, a location and an orientation of the 3D sensor.
