新一代ToF相机是能够实时重建3D场景的实用设备。它们主要受到两个因素的限制；精度和空间分辨率低。场景的标准 CCD 和 ToF 图像在某些区域具有相似之处，例如，物体边缘在两种模态中都表现为梯度。在这里，我们提出了一种克服分辨率限制的方法；在校准设置中使用有效的双树复小波变换框架将低分辨率 TOF 图像与 CCD 图像的高分辨率细节融合。我们展示了这如何增强对象边界等特征。
A new generation of ToF cameras are practical devices capable of real-time 3D scene reconstruction. They are mainly limited by two factors; accuracy and low spatial resolution. Standard CCD and ToF images of a scene share likenesses in some regions, e.g., object edges are apparent as gradients in both modals. Here we propose an approach to overcome the resolution limitation; using an effective dual-tree complex wavelet transform framework in a calibrated setup to fuse the low resolution TOF image with the high resolution details of the CCD image. We show how this can enhance features such as at object borders.
