What is panoramic photography? Introduction to panoramic photography.

We often see some panoramic photos in Weibo or some websites, which show more beautiful scenery than ordinary photos, and panoramic photos are done through panoramic photography. Let's take a look at what panoramic photography is.

Panoramic photography refers to a photography splicing method that takes a certain point as the center, shoots horizontally at 360 degrees and vertically at 180 degrees, and splicing a plurality of photographed pictures into a picture with an aspect ratio of 2: 1. Fish-eye lens is often used when shooting, and special software such as PTGUI is used when stitching. Mosaic maps need special software to drive panoramic browsing.

The so-called panoramic shooting is to piece together all the pictures into a picture of Zhang Quanjing. Its basic shooting principle is to search the edge of two pictures, overlap the areas with the closest imaging effect, and complete the automatic stitching of pictures. There are also Sony's intelligent scanning panoramic shooting function and Fuji's 360-degree mobile phone panoramic shooting function. As long as you hold DC tightly for a circle, it will automatically combine these pictures into a picture of Zhang Quanjing.

Panoramic photography is to use a camera to assemble a group of photos taken from a 360-degree scene into a picture containing all the scenes, and use special publishing software to play them online, so that visitors can drag the mouse to see any corner of the scene according to their own wishes. It makes people feel immersive, as if they were there. (The panoramic views referred to here are all spherical panoramic views, excluding cylindrical panoramic views with low technical content. )

Panoramic shooting hardware Panoramic shooting equipment generally includes SLR camera, fisheye lens, pan/tilt and tripod. According to the producer's different requirements for panoramic quality and use. The following briefly introduces several hardware configurations:

1. Configuration of common digital camera:

Cameras: There are common cameras of Nikoncoolpix series, such as coolpix5400, 5700, 8700, etc. 5400 and 5700 belong to the same level, with more than 8700 pixels, and the photos taken are all in high definition. However, there is still a gap between ordinary digital cameras and SLR cameras in definition and color reproduction. The panorama generated by this configuration is not bad for the panorama in the form of web pages.

Fisheye lens: The fisheye lens that these three cameras can match is NikonFC-E9, but they all need a matching ring. The 5700 and 8700 need UR-E 12, and the 5400 needs UR-E 10 adapter ring.

Pan/tilt: There are four kinds of pan/tilt that can be matched: JTS-rotator 9 Pan/tilt (3,000 yuan) and Manfoto 302QuickTimeVR (it is said that it has been discontinued, and some of them may survive in China, about 4,000 yuan), Manfoto 303SPH (the price should be a little more expensive than 302, which has not been sold in China) and Kaidankpaniiics (more than 0).

Tripod: Tripods can be matched at will, but because the camera, fisheye and pan/tilt are used, the weight is very heavy, so it is necessary to choose a stable corner brace, and the handle should be short, otherwise the handle will be photographed.

The configuration advantage of ordinary digital cameras is that the hardware is relatively cheap and it is very convenient to shoot and make. If the shot is good and the image is not misaligned, the later pictures don't need to be modified, and the panorama can be published directly on the Internet. Of course, clarity and color reproduction may be lacking for professional photographers. But for ordinary producers, this configuration is the most cost-effective

2. Configuration of digital SLR camera with zoom:

Camera: The commonly used cameras are Nikon SRDC (D 100, D 1, D 1H, D 1X, D2H, D70) and CanonSLRDC(D60, D30, 1D, 30).

Fisheye lens: This series of cameras can be equipped with Sigma8 MMF/4 Excricular Fisheye lens (about 4,000 yuan), Nicol 8 MMF/2.8 Fisheye lens (more than 4,000 yuan), coastal digital Fisheye lens (more than 10000 yuan, which is very expensive), and other viewing angles are greater than 180.

Yuntai: Manfutu 302QuickTimeVR, Manfutu 303SPH, Kaidan Quick Panic.

Needless to say, the advantages of SLR cameras over ordinary digital cameras are that they can shoot high-definition panoramic images. However, due to the influence of ccd size, the image taken after connecting the fisheye lens is not spherical, and the original spherical edge is cut off, forming a drum-shaped image. Because the angles of the two sides of the straight line are about 1 15 degrees, it is necessary to use software with four-fish-eye stitching function for image stitching.

3, no zoom digital SLR camera configuration:

Camera: Canon 1DS, KodakDCSPROSLR.

The lens, pan/tilt and zoom digital SLR are all the same.

This series of configurations is mainly due to the high cost, but the captured images are of good quality and color, which can be used not only for web pages, but also for full-screen panoramic display. In addition, the shooting production is also a very simple combination of two fisheye, which can be completed in a few minutes. For production units with economic strength, the configuration of this model is very good.

4. Film SLR configuration:

Cameras: Nikon, Canon, Pentax, Kodak, Seagull and other major brands have them.

Fisheye lens and pan/tilt: both have zoom digital SLR configuration.

The photos taken by the film SLR need to be scanned before they can be used. In order to avoid image loss, a higher resolution scanner is needed.
