Three Dimensional Measurement of Metal Surface Shape by Using a Stereo Pair of Sem Photographs
This paper describes analytical and digital photogrammetric methods of a stereo pair of scanning electron microscope (SEM) photographs. Analytical method was applied to a triplet of stereo SEM photographs of an impression left by the diamond indenter of Vicker's hardness tester. The height error of the three dimensional measurement was ±5% and the precision is sufficient for surface shape analy...
متن کاملMulti-Resolution Stereo Matching Using Maximum-Surface Techniques
This paper presents a fast and reliable stereo matching algorithm which produces a dense disparity map by using fast cross-correlation, rectangular subregioning and maximumsurface techniques in a coarse-to-fine scheme. Fast correlation is achieved by using the box filtering technique whose speed is invariant to the size of the correlation window, and by segmenting the images at different levels...
متن کاملRobust Stereo Matching Using Probabilistic Laplacian Surface Propagation
This paper describes a probabilistic Laplacian surface propagation (PLSP) framework for a robust stereo matching under severe radiometric variations. We discover that a progressive scheme overcomes an inherent limitation for this task, while most conventional efforts have been focusing on designing a robust cost function. We propose the ground control surfaces (GCSs) designed as progressive uni...
متن کاملStereo Matching with Direct Surface Orientation Recovery
We propose a new stereo matching algorithm which computes the depth and surface orientation simultaneously. While area-based stereo matching is an essential technique in the recovery of the dense 3D shape, conventionally it uses square windows based on the implicit assumption that intensity patterns surrounding corresponding points have no deformations between images from different views. In pr...
متن کاملStereo Matching Using Optic Flow
A method for the determination of pixel correspondence in stereo image pairs is presented. The optic ̄ow vectors that result from the displacement of the point of projection are obtained and the correspondence between pixels of the various objects in the scene is derived from the optic ̄ow vectors. The proposed algorithm is implemented and the correspondence vectors are obtained. Various speciali...
