Claim 0:
1. An image annotation system comprising:
an input configured to receive a sequence of two-dimensional images captured by an image capture device of a vehicle;
memory holding computer-readable instructions; and
one or more hardware processors coupled to the memory, the computer-readable instructions configured, when executed by the one or more hardware processors, to cause the image annotation system to:
generate a three-dimensional structure model of an environment travelled by the vehicle whilst capturing the images;
determine, for each of the captured images, a corresponding location and orientation of the image capture device within the environment when that image was captured;
generate two-dimensional image annotation data for marking regions of the images corresponding to the three-dimensional structure model, by geometrically projecting the three-dimensional structure model onto an image plane of each image that is defined by the corresponding image capture device location and orientation;
render at least one of the images and its two-dimensional image annotation data via a user interface; and
adapt the three-dimensional structure model according to instructions received via the user interface,
wherein the computer-readable instructions further configure the image annotation system to modify the two-dimensional image annotation data for each of the captured images based on the adapted three-dimensional structure model, and to render the modified annotation data for the at least one image via the user interface, thereby allowing a user to effect modifications of the two-dimensional image annotation data for multiple captured images simultaneously, using the at least one image and its two-dimensional image annotation data as a reference.
