Magnification is an important but basic calibration that is usually combined with distortion calibration or focus. Any measurement system will require a magnification calibration, even if the lenses are designed as fixed focal length. Typical methods involve test targets and should be performed on alrea...
This paper presents a three-dimensional (3D) vision-based instrumentation system for the measurement of the rate of spread and height of complex fire fronts. The proposed 3D imaging system is simple, does not require calibration, is easily deployable in indoor and outdoor environments and can han...
vision systemdimension measurementimage processingA method to develop a vision system for dimension measurement of mechanical parts based on Lab VIEW 2012 was proposed. The major emphasis was on how to create the sub-VI (Virtual Instrument), which could be embedded in an automatic vision ...
A stereo vision system for the on-line measurement of dimensional parameters of automotive gaskets was designed, set up and tested. The image processing and measurement software was suitably optimised to be run on a commercial PC so that 100% of the gaskets produced can be analysed on-line. ...
Development and application of a machine vision System for measurement of tool wear Tool wear monitoring is of great concern in machining industry, as it affects the surface qualities, dimensional accuracy and production costs of the machi... DA Fadare,AO Oni - 《Journal of Engineering &...
Online Measurement Vision System The system is developed based on vision detection technology and laser measurement technology. It works by the principle of triangulation and makes use of robot's advantage in flexible positioning to acquire the 3D spatial coordinates of the features under measurement, ...
The objective of this research was to design and implement an inexpensive computer vision system for measuring the color of a highly heterogeneous food material not only in shape as well in color such as potato chips in L∗a∗b∗ units from RGB images. The system was composed of (i)...
