Web7 de mar. de 2024 · I would like the camera to focus on an object (without changing the camera's rotation, just like the editor function does not). But I would also like it to zoom in as much as possible. So that the bounding box of the object would remain inside the camera's field of view. The FOV and rotation of the camera should never change. WebOpen the view settings panel (the button) and set the Display space to the image which you want oriented. My images are aligned in FSLeyes, but other FSL tools complain about orientation!

WebThis is known as the angular field of view (AFOV) and is required to determine the overall FOV. The AFOV is the angle between any light captured at the horizonal, and any light captured at the edge (as shown in Figure 2). If you have a fixed sensor size, altering the focal length will alter the AFOV and therefore the overall FOV.
