Abstract
A method of annotating frames of a time sequence of frames captured by at least one travelling vehicle comprises, in a frame processing system: determining a three-dimensional (3D) road model for an area captured in the time sequence of frames; receiving first annotation data denoting a known 3D location of a moving object for a first frame of the time sequence of frames; and automatically generating second annotation data for marking an expected moving object location in at least a second frame of the time sequence of frames, by assuming the moving object moves along an expected path determined from the known 3D location and the 3D road model.

A method of annotating frames of a time sequence of frames captured by at least one travelling vehicle, the method comprising, in a frame processing system:
- determining a three-dimensional (3D) road model for an area captured in the time sequence of frames;
- receiving first annotation data denoting a known 3D location of a moving object for a first frame of the time sequence of frames;
- and
- automatically generating second annotation data for marking an expected moving object location in at least a second frame of the time sequence of frames, by assuming the moving object moves along an expected path determined from the known 3D location and the 3D road model.
A processing computer system comprising:
- one or more processors configured to:
- receive a time sequence of frames captured by at least one travelling vehicle;
- determine a three-dimensional (3D) road model for an area captured in the time sequence of frames;
- receive first annotation data denoting a known 3D location of a moving object for a first frame of the time sequence of frames;
- and
- automatically generate second annotation data for marking an expected moving object location in at least a second frame of the time sequence of frames, by assuming the moving object moves along an expected path determined from the known 3D location and the 3D road model.
At least one computer-readable storage medium having encoded thereon executable instructions which, when executed on one or more processors of a computer system, cause the computer system to:
- receive a time sequence of frames captured by at least one travelling vehicle;
- determine a three-dimensional (3D) road model for an area captured in the time sequence of frames;
- receive first annotation data denoting a known 3D location of a moving object for a first frame of the time sequence of frames;
- and
- automatically generate second annotation data for marking an expected moving object location in at least a second frame of the time sequence of frames, by assuming the moving object moves along an expected path determined from the known 3D location and the 3D road model.
