VR technology

Virtual reality technology (VR) is a computer simulation system that can create and experience a virtual world. It uses a computer to generate a simulation environment to immerse users in the environment. Virtual reality technology is to use the data in real life, through the electronic signal generated by computer technology, and combine it with various output devices to transform it into phenomena that people can feel. These phenomena can be real objects in reality, it can also be a substance that we can't see with the naked eye, expressed through a three-dimensional model. Because these phenomena are not what we can see directly, but the real world simulated by computer technology, they are called virtual reality.

In recent years, it has developed rapidly. With the emergence of technologies such as 5G high-speed transmission, Internet of Things, artificial intelligence, flexible display, and mobile high-performance graphics computing cards, it has laid the foundation for the commercialization of VR technology.

VR camera

The panoramic camera encapsulates multiple sensors with different orientations inside, and the panoramic effect is obtained by splicing images of the sub-pictures. The structure of mainstream products is to encapsulate several sensors and an independent short-focus lens with a field of view angle in a unified housing. Among them, core technologies such as digital processing and compression are integrated in the front-end firmware, and several separate images are integrated into 180°, 360° or even 720° high-definition panoramic images according to user needs, and then transmitted to the back-end management platform by the network or high-speed bus.

Panoramic virtual reality uses computer technology to realize a full-scale interactive viewing of the restored panoramic images of real scenes. With the support of the playback plug-in (usually Java or QuickTime, ActiveX, Flash), use the mouse to control the direction of the look around, which can be left, right, close or far. It makes the audience feel in the live environment, as if viewing the great scenery outside in a window.

Especially with the development of network technology, its superiority is more prominent. It has changed the plain characteristics of the traditional network, allowing people to observe panoramic views on the Internet, and through interactive operations, they can browse freely and experience the three-dimensional VR panoramic visual world.

360 VR used in the inspection industry

Production monitoring and virtual audit can also be done with VR360 camera, importers who can’t travel to factory can navigate wherever they want in the factory, like a live factory tour.

Although 360 VR can provide client 3D panoramic visual experience, it does not mean the the inspector is not needed, or just a photographer is enough. The inspection/audit checkpoints shall still be verified by inspectors, e.g. if the factory workers/QC’s strictly follow the instructions, if the machine setting is right, and so on. By the way, for VR camera with legs it is still time consuming to set up in different production lines or stages.
