WebFeb 13, 2013 · n.b. the whole "angle of human vision" thing is utter nonsense, it even says in the wikipedia article you link to that human vision is more like 104 degrees (it later goes to claim that 53 degrees is the angle of sharp human vision, which is also nonsense and even if it weren't that value would still be meaningless as the brain does so much processing you … WebThis is the focal length of the lens. Then, the arrow labeled Y1 is the image plane (where the sensor sits). If the sensor has the half-size of y1, then the angle of the green line with the horizontal is half your field of view. Basic geometry can give you the FOV: FOV = 2 * arctan(y1 / f) Mind two things: Units. y1 is the half-size of your sensor.

WebField of View (FoV): total area that can be viewed by the lens and imaged onto the camera sensor. Working distance (WD): object to lens distance where the image is at its sharpest focus. Depth of Field (DoF): maximum range where the object appears to be in acceptable focus. Sensor size : size of the camera sensor’s active area. WebWhere a 50mm fixed lens has a 47-degree field of view on a full frame camera, a 31mm lens has a 47-degree field of view on a 1.6x crop sensor camera.

"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. " - Photography lens distance vs field of view

WebField of view (FOV) is the open observable area a person can see through his or her eyes or via an optical device. In the case of optical devices and sensors , FOV describes the angle … WebFor example, a typical zoom lens might have a focal length of 18-55mm, or 24-70mm. Focal length comes from the distance between a specific part of a lens (the “optical centre”) and the image sensor (or film plane) where the image is recorded. The wider the angle of view that a lens offers, the smaller this distance, and the lower the number.
