Up to now, there are at least four commonly used stereoscopic 3D transmission formats, called frame sequential (frames continuous), frame packing (frame encapsulation), side-by-side (side-by), and Checkerboard (chessboard).Frame sequential (continuous frames), at some level, is the simplest 3D format. Frame sequential signal is a full-solution image sent at a rate of 120 frames per second. The frames alternate sequentially, so the display device recei

These two days I have been studying things related to stereoscopic vision, using a combination of opencv2.0 + vs2005. Opencv is a very powerful library of computer vision. With it, many complex algorithms can be implemented through a few simple functions. Of course, the premise is that you have to configure various variables and matrices that the function needs to call. Too many variables need to be prepared to call some complex opencv functions, whic

In general, the 24mm is already a wide-angle lens (Aps-c is 18mm) under the full picture allows you to incorporate a lot of landscape content into the photo, but there is another, more wide-angle lens that can reach 16mm (full width) or 10mm (APS-C), and these lenses
