| “Virtual reality technology is a computer simulation system that can create and experience a virtual world.It uses a computer to generate a simulation environment.It is a system simulation of multi-source information fusion and interactive threedimensional dynamic visual and physical behavior.The user is immersed in the environment.” As a definition of VR this is really too complicated to say,but we can see from the definition that the meaning of VR is to make people “immersive”,and how to enhance immersion is VR today A core topic in the research field,after reading a large number of documents and foreign papers,as well as their own years of game experience and VR's personal experience,I found that the virtual presence enhances the sense of immersion is huge.The so-called virtual presence is not only putting your brain in the virtual world,but also projecting your body into the virtual world in real time.When the body is visible,it has a true tactile sensation,which will bring about a qualitative change in the immersion of the player in a virtual environment.As for how to implement it,here I chose to use a 3D camera to shoot the human body in real time,and at the same time transmit it to a well-built virtual environment with low latency,and associate it with the headlight main view to realize virtual presence.Although there are many 3D cameras on the market today,they are very few people.After consulting data and teaching guidance,I discovered that the low-cost KINECT can be used as a 3D camera,but due to its initial image Two kinds of color image and depth image,need to use the mapping function to calibrate and fuse the image,and then use reverse engineering to rewrite the interface protocol to enable real-time streaming to achieve the effect of the 3D camera that I want.At the same time,on the basis of new hardware changes,evolution and improvements have been made,finally combine with the head image to locate the image to achieve virtual presence. |
