IEE Colloquium on '3D Imaging and Analysis of Depth/Range Images' (Digest No.1994/054)
High-accuracy 3-D measurement using multiple camera views
A method which has not received high prominence in the machine vision community is that of multi-camera measurement. There are advantages to be gained from using multi-camera views: (i) redundancy of measurement; (ii) statistical feedback; ...
3D measurement using stereo scene coding
This paper outlines the hardware and software developments that have resulted from the active stereo probe (ASP) project's investigation into 3D surface recovery using structured pattern projection. Scene objects are illuminated by patterns...
Reverse engineering in industrial applications using laser stripe triangulation
In many fields of industry it is necessary to obtain shape information from physical objects. The diversity of items which need to be measured is huge but their shape properties can be broadly classified into two categories: regular, consis...
Real-time tracking of surfaces with structured light
At Oxford University much research has recently been focused on active vision, and in particular dynamic contours. These deformable model curves are able to track objects in an image using dynamic models of the behaviour of the target which...
Fusion of intensity and range data
Recent work to improve the robustness of computer vision has included investigation of sensor fusion. The authors introduce a visual architecture, which has several parallel processes operating in a reconfigurable, concurrent architecture. ...
Acquisition of CAD models from multiple range views
The project reported focuses on the automatic acquisition of CAD-like models of industrial components from multiple range images. The models are intended to be suitable firstly for use in industrial vision applications such as object inspec...
