Abstract
A technique of monitoring and/or tracking an object includes scanning a set of beams of electromagnetic radiation in lines over the object; obtaining data indicating a velocity of the object and position of the object out of the plane as the beam of electromagnetic radiation is scanned over the object; and performing a correction operation to produce a correction to the absolute position in the plane of the object at a later time after an initial time, the correction being based on the obtained data.
Claims18
A method comprising:
- receiving, by processing circuitry, a video frame including (i) an image of an object located at an absolute position in a plane and (ii) a timestamp indicating an initial time at which the object was located at the absolute position in the plane;
- scanning, by the processing circuitry, a set of beams of electromagnetic radiation in lines over the object;
- obtaining, by the processing circuitry, data indicating a velocity of the object and position of the object out of the plane as the beam of electromagnetic radiation is scanned over the object;
- performing, by the processing circuitry, a correction operation to produce a correction to the absolute position in the plane of the object at a later time after the initial time, the correction being based on the obtained data.
A computer program product comprising a nontransitory storage medium, the computer program product including code that, when executed by processing circuitry of a computer, causes the processing circuitry to perform a method, the method comprising:
- receiving a video frame including (i) an image of an object located at an absolute position in a plane and (ii) a timestamp indicating an initial time at which the object was located at the absolute position in the plane;
- scanning a set of beams of electromagnetic radiation in lines over the object;
- obtaining data indicating data indicating a velocity of the object and position of the object out of the plane as the beam of electromagnetic radiation is scanned over the object;
- performing a correction operation to produce a correction to the absolute position in the plane of the object at a later time after the initial time, the correction being based on the obtained data.
An electronic apparatus, comprising:
- memory;
- and
- controlling circuitry coupled to the memory, the controlling circuitry being configured to:
- receive a video frame including (i) an image of an object located at an absolute position in a plane and (ii) a timestamp indicating an initial time at which the object was located at the absolute position in the plane;
- scan a set of beams of electromagnetic radiation in lines over the object;
- obtain data indicating data indicating a velocity of the object and position of the object out of the plane as the beam of electromagnetic radiation is scanned over the object;
- perform a correction operation to produce a correction to the absolute position in the plane of the object at a later time after the initial time, the correction being based on the obtained data.
