The surface model is used to generate the hand shape based on the posture obtained from the dynamic model.

In this work, we address the problem of merging multiple textured 3-D data sets, each of which corresponds to a different view of a scene or object. There are two steps to the merging process: registration and integration. To register, or align, data sets we use a modified version of the Iterative Closest Point algorithm; our version, which we call color ICP, considers not only 3-D information, but color as well. We show that the use of color decreases registration error by an order of magnitude. Once the 3-D data sets have been registered we integrate them to produce a seamless, composite 3-D textured model. Our approach to integration uses a 3-D occupancy grid to represent likelihood of spatial occupancy through voting. In addition to occupancy information, we store surface normal in each voxel of the occupancy grid. Surface normal is used to robustly extract a surface from the occupancy grid; on that surface we blend textures from multiple views.","PeriodicalId":337843,"journal":{"name":"Proceedings.

The availability of the technology is just the first step in applying surface scanning to engineering anthropometry; several issues remain to be resolved to make these tools useful for engineering applications. One important issue is the standardization of positioning and the posture of the subject for scanning. In engineering it is not enough to be able to measure one individual one time in one posture, but it is also necessary to measure the individual in different postures and compare the individual with many other people who have been comparably measured. Not surprisingly, people can be more difficult to measure precisely than fixed stationary objects. In the process of developing standardized procedures for surveying the civilian populations of North America and Europe, an experiment was conducted to determine optimal scanning positions. While this experiment used just one type of scanning technology, many of the methods are transferable to other methods as well. This paper discusses the results from that investigation.","PeriodicalId":337843,"journal":{"name":"Proceedings. International Conference on Recent Advances in 3-D Digital Imaging and Modeling (Cat.

It combines surface reconstruction techniques with object recognition for the generation of 3-D models for computer graphic applications. The system permits the insertion of highlevel constraints, like a specific angle between two house walls, in an explicit knowledge base implemented as a semantic net. The applicability of those constraints is proved by asserting and testing hypotheses in an interpretation phase. In the case of rejection a more general constraint or model is selected. The capabilities of the system were shown for the modeling of buildings using depth from stereo and contour information. The system reconstructs the surface of the scene objects using the constraints selected in the prior interpretation.","PeriodicalId":337843,"journal":{"name":"Proceedings.

One of them is the precise understanding of optical properties of objects, which is possible to obtain from 3D plus brightness or color data. Those properties are usually important inspection criteria; for example, the specular sharpness of a coatted surface is usually related to the coating quality. This paper is related to a procedure for recovering the specular sharpness and other surface-related properties from objects. The current approach works on 3D plus brightness or color data, which are retrieved in two steps using a common structured-light triangulation-based technique and an ordinary non-structured spot light. Some experimental results obtained on industrial parts are also shown.","PeriodicalId":337843,"journal":{"name":"Proceedings.

The term hybrid refers to a combination of edge- and region-based considerations. A reliable computational procedure which takes the range image discontinuities into account is presented for computing the pixel's normal. The segmentation algorithm consists of two parts. In the first one, the pixels are aggregated according to local properties derived from the input data and are represented by a region adjacency graph (RAG). At this stage, the image is still over-segmented. In the second part, the segmentation is refined thanks to the construction of an irregular pyramid. The base of the pyramid is the RAG previously extracted. The over-segmented regions are merged using a surface-based description. This algorithm has been evaluated on 80 real images acquired by two different range sensors using the methodology proposed in (Hoover et al., 1996). Experimental results are presented and compared to others obtained by four research groups.","PeriodicalId":337843,"journal":{"name":"Proceedings.
