What is camera motion estimation?

Motion estimation is the process of determining motion vectors that describe the transformation from one 2D image to another; usually from adjacent frames in a video sequence. It is an ill-posed problem as the motion is in three dimensions but the images are a projection of the 3D scene onto a 2D plane.

How do you calculate motion blur on a camera?

Motion Blur = Camera Shutter Interval(s) x Drone Speed(m/s). As a general rule, your motion blur should not be greater than 1 x Ground Sampling Distance (GSD), where GSD is the distance on the ground for every 2 adjacent pixels in the image.

What is roll camera movement?

Roll. The camera roll is a rotational camera movement that rotates the camera over its side on its long axis. Rolls can be dizzying and unnatural. For this reason, filmmakers use it to disorient the audience or create uneasiness.
