近年来，计算机视觉在从二维图像中重建深度信息方面取得了重大进展。一个新的挑战是将这些技术扩展到视频图像。给出一小组校准的摄像机，我们的目标是从新的视角实时渲染在线动态场景。本文提出了一种基于图像的绘制系统，该系统使用摄影测量约束，而不需要任何场景几何知识。我们的方法遵循平面扫描算法，通过处理遮挡的局部动态评分进行扩展。此外，我们还提出了一种优化的立体绘制方法，以较低的代价计算第二幅图像。我们的方法在消费者图形硬件上实现了实时帧速率，这要归功于片段着色器。
Recent research in computer vision has made significant progress in the reconstruction of depth information from two-dimensional images. A new challenge is to extend these techniques to video images. Given a small set of calibrated video cameras, our goal is to render on-line dynamic scenes in real-time from new viewpoints. This paper presents an image-based rendering system using photogrametric constraints without any knowledge of the geometry of the scene. Our approach follows a plane-sweep algorithm extended by a local dynamic scoring that handles occlusions. In addition, we present an optimization of our method for stereoscopic rendering which computes the second image at low cost. Our method achieves real-time framerate on consumer graphic hardware thanks to fragment shaders.
