Abstract
An object tracking apparatus, method and computer-readable medium for detecting an object from output information of sensors, tracking the object on a basis of a plurality of detection results, generating tracking information of the object represented in a common coordinate system, outputting the tracking information, and detecting the object on a basis of the tracking information.
Claims15
An object tracking system comprising:
- at least one memory storing instructions;
- and
- at least one processor configured to execute the instructions to perform:
- generating, via a first detector, a first detection result of an object from a first image;
- generating, via a second detector, a second detection result of the object from a second image, the second image being different from the first image;
- calculating first position information of the object represented in a common coordinate system based on the first and second detection results;
- transforming the first position information of the object represented in the common coordinate system to first transformed position information of the object represented in an individual coordinate system for the first detector;
- transforming the first position information of the object represented in the common coordinate system to second transformed position information of the object represented in an individual coordinate system for the second detector;
- generating, via the first detector, a third detection result of the object from a third image based on the first transformed position information of the object;
- and
- generating, via the second detector, a fourth detection result of the object from a fourth image based on the second transformed position information of the object.
