Introduction to 360-degree panorama

360-degree panorama is to capture the image information of the whole scene with a professional camera, combine the pictures with software and play them with a special player, that is, to turn plane photos and computer pictures into a 360-degree panoramic landscape. Simulate a two-dimensional plane into a real three-dimensional space and present it to the viewer. It also provides viewers with various functions of manipulating images, and can zoom and move the scene in all directions to achieve the effect of simulating and reproducing the real environment of the scene. Compared with previous forms such as shapes and pictures, the advantages of 360-degree panoramic view are mainly reflected in the following aspects:

(1) has a strong sense of reality and is made based on real pictures, which is more realistic than other modeling objects.

(2) It can express more image information than plane pictures, and can be controlled at will, with good interactive performance.

(3) Through the perspective processing of the image, the real three-dimensional real scene is simulated, which has a strong sense of immersion and brings an immersive feeling to the viewer.

(4) convenient generation, short manufacturing cycle and low manufacturing cost.

(5) The file is small, the transmission is convenient, it is suitable for network use, and the release format is diverse, which is suitable for various forms of applications.

360-degree panorama is a virtual reality technology based on static images on microcomputer platform. Let people have a 360-degree panorama on the computer, and browse freely through interactive operation, thus experiencing the three-dimensional VR visual world. 360-degree panorama consists of panoramic photography and virtual panoramic photography. Panoramic photography refers to a Zhang Quanjing image that is made by stitching a group of photos with a 360-degree camera ring through seamless processing, while panoramic image refers to photos that are larger than the normal effective visual angle of both eyes (about 90 degrees horizontally, about 70 degrees vertically) or the residual visual angle of both eyes (about 180 degrees horizontally, about 90 degrees vertically) or even the complete scene range of 360 degrees. Then use certain network technology to restore the real scene and show it on the Internet, which has strong interactivity, allowing you to control the direction of looking around with the mouse, which can be left or right, up or down, near or far, big or small, and make you feel immersive. This is the so-called virtual panorama.

With the rapid growth of the 360-degree panoramic market, 360-degree panoramic technology providers are constantly emerging. With the increasing market demand and application of 360-degree panoramic view, people can better reconstruct, experience and transform reality in the virtual world of computers and networks through in-depth research on virtual reality visualization technology. Panorama can reproduce the scene more comprehensively and make people feel immersive, so it is often used for exhibition purposes. For example, you can use a panoramic view to show real estate, tourist attractions, cars, hotels, campuses, sports venues, company office environment and so on.

(1) HD: Through continuous development and improvement, we have higher definition and resolution than the pictures provided by our peers while ensuring the playback speed and window size. The highest resolution of the picture can reach12.5 million pixels; The maximum window can reach1024× 768;

(2) Suspension technology: get rid of the bondage of tripod, break the conventional imagination limit, and create a brand-new perspective, with a foothold rising into the air and no supporting points around. Especially from the perspective, it presents a steep, spectacular and unique sensory effect;

(3) Macro technology: through the detailed description of the tiny space, we can show the scenes that people usually ignore and realize close-up viewing;

(4) Sports technology: display moving objects, so that people can grasp and feel the instantaneous beauty of sports;

(5)360-degree column technology: use zoom lens to display open areas, which is suitable for large-scale buildings or buildings, coastlines, vast deserts, etc.

(6)360-degree spherical technology: advanced shooting and graphic synthesis technology are adopted to make the image angle of view reach 360 degrees ×360 degrees, that is, up, down, left and right omni-directional angles;

(7) Personalized player: The player types are Swf, Java, QuickTime,. EXE etc. , thus greatly enhancing the customer image.

A 360-degree panorama is an image whose viewing angle exceeds the normal viewing angle of a person, and what we mean here is an image with a horizontal viewing angle of 360 degrees and a vertical viewing angle of 180 degrees. Panorama is actually just a plane picture generated by mapping the surrounding scenes according to a certain geometric relationship. Only through the correction of panoramic player can it become a three-dimensional panorama. 360 panorama, as the name implies, is a real 360-degree all-around image, giving people a three-dimensional sense. The three biggest characteristics of this map are: 1, which shows all the scenery in the sphere of 360 degrees in an all-round, all-round and comprehensive way; You can press and drag with the left mouse button in the example to watch all directions of the scene; 2. Scenes: Real scenes, real scenes and three-dimensional panoramas are mostly patchwork images based on photos, which keep the authenticity of the scenes to the maximum extent; 3.360: 360-degree panoramic view, although the photos are all flat, but the 360-degree panoramic view obtained through software processing can give people a three-dimensional sense of space, so that the viewer seems to be in it.
