Classification: CPC B  G | IPC B  G

Claim 10:
11. The computer-implemented method of claim 1, wherein deriving, from the second sequence of image pairs captured by the stereo camera, the second track for the given agent comprises:
detecting the given agent in each of a subset of image pairs in the second sequence, wherein each image pair in the subset of image pairs was captured at a respective capture time;
for each image pair in the subset of image pairs, (i) identifying a pair of corresponding tracking points within the image pair that represent a common reference point of the given agent, (ii) applying triangulation to the identified pair of corresponding tracking points within the image pair in order to determine a three-dimensional (3D) position of the common reference point of the given agent, and (iii) using the determined 3D position of the common reference point of the given agent to determine a 3D position of the given agent at the respective capture time of the image pair; and
deriving the second track based on the determined 3D positions of the given agent at the respective capture times of the image pairs in the subset of image pairs.
