The Generation Of Spherical Panorama Based On Smart Phone And Fisheye Lens

In recent years,virtual reality has set off a boom in the industry,and technology research related to virtual reality has become a hot spot.Panorama technology has become the most popular technology for providing quick and easy experience for virtual reality.However,dedicated panoramic shooting equipment is more expensive,and ordinary cameras need to shoot more images and less registration accuracy restrict the popularity of panorama technology.With the rapid spread of smart phones,mobile phones have become an indispensable necessities in people's lives.Based on the above background,we put forward a new method is to combine the smart phone and fisheye lens,shooting four photos to complete the panorama of the splicing,greatly reducing the cost of making the panorama.In the process of splicing,this paper makes full use of the advantages of the smart phone gyroscope to detect the gesture of the mobile phone in real time,obtains the rotation matrix of the captured image,and then calculates the relative Euler angle between the images to complete the image registration.Compared with the traditional registration method,this method effectively improves the registration accuracy,and more efficient.Further,the whole process of image splicing is ported to the OpenGL Shader program to take advantage of the efficient computing power of the GPU to speed up.Compared with the CPU splicing,this use of GPU-accelerated splicing efficiency increased by 5-6 times.Experiments show that this method can accurately complete the splicing of the spherical panorama on the mobile phone platform,and has high splicing efficiency.
