doi:10.3969/j.issn.1000-1093.2018.05.022

Abstract

Abstract: A method for registrating the virtual reality without identification is presented for virtual reality registration of optical see-through automotive head-up display (HUD) in augmented reality system. The composition of HUD system is introduced, the coordinates of each part of the system are defined, and the transformation relations of each coordinate system are established. The initial registration matrix is obtained. Then the image pairs are got to extract the features of image, and the relationship between the images is established by using the method of gray measuring error. Finally, the virtual reality registration matrix of HUD system is obtained by synthesizing the initial matrix and the current matrix. The experimental results show that the correlation distance between the registered value and the real value of the system is 0.088 9, which meets the requirement of registration accuracy. Compared to other methods, the algorithm speed has been improved.Key
