Hardware Chapter Camera Node--Panoramic Camera

========================
【Concept】
 
    Panoramic camera called the panoramic camera.
 
=========================
【Principle term】
 
 1. The optical axis of the camera in the vertical direction as the route from the wide-angle camera photography when the other side to side scanning.
 2. The use of such a small field angle camera lens, lens or optical components (mirrors flies) motion scanning feature (in the direction perpendicular to the flight direction of movement), the camera will continuously change the optical axis point, enabling the expansion of the transverse width of panoramic photography.
 3. The exposure time by changing the direction of flight parallel to and close to the size of the image plane of the slit to control.

=========================
【Features Terminology】
 
     High resolution, large width;
     Geometry is not strict, there is a panoramic distortion, distortion and image motion compensation scanning position distortion.
 
=========================
【Term Category】
 
 -------------------
 (1) [light law type] (sub-scanning)
 
     When the camera lens around the axis of rotation, reverse synchronized motion film, there are strict speed synchronization requirements, a higher resolution.

 -------------------
 (2) [node type] (direct scanning)
 
     When the camera lens rotation about an axis through the rear node or swing by flattening film stationary on a flat circular exhibition, speed synchronization requirements, high resolution.
 
 -------------------
 (3) [prism scanning]
 
     When the camera, in front of the lens rotating prism scanning feature, film, and sports as for speed synchronization, but a lower resolution.
=========================
【Use the term】
 
     In general, the panoramic camera mainly for shooting scenery, collective commemorative photo, captured images have a high-resolution, accurate color reproduction, rich layers, especially for group shots, from dozens of people on thousands of people can shoot, and there is no distortion, and everyone is very clear.
