Hi,

I have got a question regarding the camera view from a camera sensor. To me it seems that the view after having 'applied a viewport' for a camera sensor is widescreen instead of its normal view. I have got a point cloud in which the cars seem to be stretched instead of their normal size.

Is this because some option is selected? Or is this just the general view from a viewport?

Not particularly. There might be an error with the sensor parameters? How was the sensor created/imported?

The sensor was created via Edit -> sensors -> camera -> create, and then inserting the coordinates of the starting point and the size of the camera display view.

Can you maybe post here some screenshots of the camera parameters?

Hi,

Yes! Here they are in the table:

Centre X coordinate (right) Y coordinate (up) Z coordinate (inv. view dir.)
-45.984001 0 50 0
-18.527000 0 0 50
47.273487 20 0 0

I have tried altering the X, Y and Z coordinates, all to 0 but then the view of the camera becomes tiny, and the green lines of the camera view disappear. Therefore the parameters are 20, 50 and 50: it is for the size of the field of view, otherwise the camera wasnt visible

Yes, I think you should normalize the vectors (i.e. so that they have a norm equal to 1).
