Such 2D representations allow us then to extract 3D information about where the camera is and in which direction the robot moves.

It is a form of optical aberration in which straight lines in the scene do not remain straight in an image. Examples of lens distortions are barrel distortion and pincushion distortion, cf. Fig. 1.28. Fig. 1.28.
WebI built an optical projector to observe the Venus transit with a 10x50 monocular. I mounted the monocular inside a box, leaving a small window to observe the projection. The focusing capability of the monocular was necessary to get a good image. The Sun's image was large and bright and detailed, much better than a pinhole projector. WebBecause we know the light ray from captured object (x0,y0) comes through the pinhole (0,0), the change in horizontal direction is x0 - 0 and on vertical y0-0. The slope of the ray of captured object is therefore x0/y0. And because the point (x1,y1) on the image plane is the same light ray, therefore it lies on the same line as the captured ...

WebPinhole Optics and Resolution Most optical devices rely on refraction or reflection to provide an image on a screen or film plane. A pinhole camera is a device which uses neither lenses nor mirrors to produce its image, but rather only a small circular aperture, or ‘pinhole’.
