Example Files
Data files including a prototype design for heading (hdg
) were published as part of the Testbed-19 Hillyfields Bubble dataset.
A hdg
attribute was included in VMT files under the SceneGraph/Bubble/TrafficSync/StaticCameras subdirectory to indicate the heading of static cameras.
Background
Vehicle tracking work in OGC Testbed-19 has highlighted a requirement to record the direction in which an object is facing - such as a camera.
Issue
Passing vehicles were observed in Testbed-19 by static cameras at locations alongside a road. A method was devised to track a vehicle path from geotagged footage using sight lines which requires the location and heading of the camera to be known.
WebVMT supports location data natively, but orientation information such as heading is not supported in the 19 September 2023 Group Note.
Discussion
A possible workaround to include heading is to encapsulate this in synchronized data using either a GeoPose or a simple heading value. Both options were studied in Testbed-19 which raised a number of issues:
Proposal
Add heading in degrees as an optional component of location.
