Question about the WC2014 camera pan,tilt,zoom parameters #28

Open gothera opened 1 year ago

gothera commented 1 year ago

So the paper mentions that the images from WC2014 were pre-processed to get the range of these parameters in them: pan, tilt and focal length ranges ([−35◦,35◦], [−15◦, −5◦] and [1000, 6000] pixels. Does anyone know more info on how those were got/obtained ? Also, in synthetic.utils.py, there is the following line: camera_data = np.asarray([640, 360, 3081.976880, 1.746393, -0.321347, 0.266827, 52.816224, -54.753716, 19.960425]) which I think it's exactly those hard-coded parameters out of nowhere. It would be really helpful to know more info/the approach used to get these for the images in the dataset. Thanks! cc @lood339

These parameters are estimated from the training dataset. They are used as the prior (known knowledge).

Hi, could you tell me how to calculate these parameters from dataset ? or share some advance to me. I’m glad to see your reply.
