Qualitative object information #8

Closed alex-mitrevski closed 4 years ago

alex-mitrevski commented 4 years ago

For describing object qualitatively (and also for matching objects to ontology entities more easily), it would be useful to add some qualitative information to the Object message.

I can think of colour and shape as the two most obvious qualitative characteristics, as both of these could be (relatively easily) extracted from the information about a detected object (e.g. the dominant colour of the object in the image could be taken as the object's colour; the shape could be extracted by fitting different common shapes to the object and taking the one that has the highest fit). Any other ideas are welcome.

I'll close this now; messages for colour and shape were added with PR https://github.com/b-it-bots/mas_perception_msgs/pull/9

We can reopen the issue if we realise there's a need for additional descriptive fields.
