Automated Model Acquisition from Range Images with View Planning
نویسندگان
چکیده
We present an incremental system that builds accurate CAD models of objects from multiple range images. Using a hybrid of surjlace mesh and volumetric representations, the system creates a “water-tight” 3 0 model at each step of the modeling process, allowing reasonable models to be built from a small number of views. We also present a method that can be used to plan the next view and reduce the number of scans needed to recover the object. Results are presented for the creation of 30 models of a computer game controllel; U hip joint prosthesis, und U mechunicul strut.

View planning for the 3D modelling of real world scenes
In recent years, several methods of reconstructing 3D scenes from range images have been proposed. Currently, the factor limiting a fully automated reconstruction process is the lack of a sufficiently scalable planning algorithm for the acquisition step. Here, we present a novel technique of iteratively planning the next view for a range scanner in an initially unknown, large indoor environment...
متن کاملThe view-cube: an efficient method of view planning for 3D modelling from range data
When aiming at the automated reconstruction of real world scenes from range images, one has to address the problem of planning the image acquisition. Although solutions for small objects in well defined environments are already available, the insufficient scalability of these approaches to large scenes and to a high number of degrees of freedom limits their applicability. In this paper, we pres...
متن کامل3-D Modeling from Range Imagery: An Incremental Method with a Planning Component
In this paper we present a method for automatically constructing a CAD model of an unknown object from range images. The method is an incremental one that interleaves a sensing operation that acquires and merges information into the model with a planning phase to determine the next sensor position or “view”. This is accomplished by integrating a system for 3-D model acquisition with a sensor pl...

This report is on the Lehigh/Columbia MURI contract. While the original focus was on sensors for manufacturing, the natural evolution of our basic research has led us to more general problems in more generic settings. As a multifaculty multi-disciplinary project much of the work is naturally done in smaller subgroup. The major results over the past year were on 3D modeling/sensor planning, omni...
متن کامل3D reconstruction of indoor environments
This paper presents a new 3D scene analysis system that automatically reconstructs the 3D model of real-world scenes from multiple range images acquired by a laser range finder on board of a mobile robot. The reconstruction is achieved through an integrated procedure including range data acquisition, geometrical feature extraction, planning the next view, registration and integration of multipl...
