Documentation and simplification of the rotation matrix convention for pano #17

Open gmaillet opened 8 years ago

gmaillet commented 8 years ago

The rotation matrix from the cameraMetaData json file is multiplied by three other matrix in sensor.js (itownsWay, Photogram_JMM, photgramme_image): why? Maybe for historical reasons related to the Stereopolis mobile mapping system. It's time to clean that and to write the documentation (for example, explain the process for using rotation matrix from a MicMac process).

I confirm that these are legacy transforms to enforce undocumented frame conventions for Stereopolis datasets. I agree that these "convention matrixes" should go to the json metadata files to streamline the general case in Sensor.js.

Is this a blocker for 1.0 release or can it wait for 1.1 ?

gmaillet commented 8 years ago

It's not a blocker, just a good oportunity to release the 1.1 soon.
