Research And Application Of Multiplanar Projection Fusion Technology

With the development of computer graphics and image technology,stereoscopic projection display technology has become a research hotspot in recent years.Stereoscopic projection display system and the application of augmented reality technology are closely combined to build a virtual and real interactive environment.The multi-plane projection fusion technology can process the images displayed by multiple projectors and realize the seamless Mosaic display of the large screen,so that the multi-plane and multi-projector display system with different shapes can project a visual seamless picture.Aiming at the problems encountered,this paper designs and implements a multi-plane projection fusion system by processing the image geometric correction,color correction,edge fusion and other technologies.The main research results are as follows:The edge fusion technique is studied because the fusion function of the same plane can only solve the situation that two projectors project in the same plane but cannot solve the situation that the projectors project in different planes.In this paper,an edge fusion algorithm suitable for different planes is proposed,which is suitable for the overlapping regions of polygons in the real scene.In the case that the fusion band is at the corner with the same plane edge fusion function,there are dark blocks in certain areas at the corners of the middle fusion band.The reason for the dark blocks is that the image brightness is attenuated in the non-overlapping area.The edge fusion function of different planes proposed in this paper can well solve the dark block problem in the corner of the fusion zone and show a picture with uniform brightness.The edge fusion technique is studied for the light bands generated by simply overlapping the adj acent proj ected images.In this paper,a hybrid attenuation algorithm is proposed,which combines the triangle attenuation algorithm and exponential attenuation algorithm to attenuate the brightness of the high-brightness fusion zone obtained in the geometric correction step.Using the proposed hybrid damping algorithm can effectively solve the exponential decay area to the fusion area gradient algorithm china-africa fusion obvious problems,can solve the triangle algorithm fusion zone in the middle area brightness decay rapidly and lead to the middle section of dark with obvious problems,while maintaining the exponential decay algorithm fusion area brightness uniformity and triangle attenuation algorithm fusion area and the advantages of smooth transition between the fusion area,the brightness of the fusion area and not the brightness of the fusion area,presents a complete seamless image.
