The street view technology is so powerful now, how did it come out?

360-degree panorama is a virtual reality technology based on static images on microcomputer platform. Let people have a 360-degree panoramic view on the Internet and browse freely through interactive operation, so as to experience the three-dimensional VR visual world. The 360-degree panorama consists of two parts: panoramic photography and virtual panoramic photography refer to a Zhang Quanjing image which is formed by seamless processing of a group of photos with a 360-degree camera ring, while the panoramic image refers to photos which are larger than the normal effective visual angle of eyes (about 90 degrees horizontally and 70 degrees vertically) or the corner visual angle of eyes (about 180 degrees horizontally and 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. You can drag the image up and down, left and right, back and forth with the mouse, and you can also place hot spots inside the image. Click it to switch scenes back and forth. In addition, you can insert voice explanations, pictures and text descriptions. Field shooting, strong sense of reality; 360 panorama is a cost-effective virtual reality solution. 360 panoramic photography uses real photos to obtain a three-dimensional sense, which is beyond the reach of general pictures and three-dimensional modeling. 360-degree panoramic photography and general pictures can play the role of display and recording, but general pictures have limited viewing angle and no three-dimensional sense, while 360-degree panoramic photography not only has a 360-degree viewing angle, but also can bring three-dimensional sense, so that observers can immerse themselves in it. Three-dimensional modeling and immersion are undoubtedly stronger than 360 panorama, but the production of three-dimensional modeling needs a lot of manpower and material resources, especially to achieve a very real degree, while the shooting and production of 360 panorama is relatively simple and convenient, especially the data volume is very small, the system requirements are low, and it is suitable for various ways and watching on various terminal devices. Therefore, 360 panoramic view can not only record the scene of a place in all directions, but also allow us to show the real scene of a place in three dimensions, so the display mode and recording means with high cost performance are beyond the reach of ordinary pictures and three-dimensional modeling. When we need to reproduce a scene truly, intuitively and comprehensively for recording or displaying, 360 panoramic view is undoubtedly the best choice.
