Symmetric camera
WebField of view (FOV) is the maximum area of a sample that a camera can image. It is related to two things, the focal length of the lens and the sensor size. Figure 1 shows a comparison between the field of view and the size of the sensor. Assuming that the focal length of the lens is the same, the larger the sensor the larger the field of view. http://www.bobatkins.com/photography/technical/lens_misalignment.html
Symmetric camera
Did you know?
In machine vision the lens focal length and image sensor size sets up the fixed relationship between the field of view and the working distance. Field of view is the area of the inspection captured on the camera’s imager. The size of the field of view and the size of the camera’s imager directly affect the image resolution (one determining factor in accuracy). Working distance is the distance between the back of the lens and the target object. WebThe radial model can be applied to many camera configurations and in particular to non-central catadioptric systems with mirrors that are symmetric around an axis coinciding with the optical axis.

WebFeb 10, 2003 · In Section 2, we establish a lemma introducing a virtual camera, symmetric to the camera that produced the input image with respect to the object's symmetry plane. In Section 3, we establish a lemma linking the symmetry lines and epipolar lines in images of a symmetric scene taken by cameras in symmetrical locations.
