An asset of epipolar navigation is the fact that
it:
Correct Answer
C. Can be done from a single observation frame
Explanation
Epipolar navigation is a method of determining the position and orientation of a moving object by analyzing the images captured from a single observation frame. This means that it does not require multiple frames or images to calculate the object's location. Instead, it uses the concept of epipolar geometry, which relates the position of an object in one image to its corresponding position in another image. By analyzing the geometry of the observed object and its corresponding epipolar line in the image, the object's position can be determined accurately. Therefore, the correct answer is that epipolar navigation can be done from a single observation frame.
