Vision System Calibration and Sub-pixel Measurement of Mechanical Parts
In this article a measuring system based on artificial vision techniques is described. Even if this problem is not new, several aspects, including sub-pixel algorithms, system programming and lighting, that are addressed in this paper, are still under study. Among them, the vision system calibration is focused. The theoretical model and the practical details of a fast method for 2-D problems ar...
متن کاملPractical Issues in Pixel-Based Autofocusing for Machine Vision
Different autofocusing methods exist for many cameras today. While not ignoring commercially available methods requiring specialized hardware, this paper focuses mainly on pixel based autofocusing algorithms as applied to CCD camera systems. Different measures of image sharpness are compared. For each of these, different algorithms for searching the best lens setting are assessed in terms of pe...
متن کاملLine Based Camera Calibration in Machine Vision Dynamic Applications
The problem of dynamic camera calibration considering moving objects in close range environments using straight lines as references is addressed. A mathematical model for the correspondence of a straight line in the object and image spaces is discussed. This model is based on the equivalence between the vector normal to the interpretation plane in the image space and the vector normal to the ro...
متن کاملCalibration of Machine Vision System for Nondestructive Detection of Plants
The detection of plants based on a machine vision system is one of the most important parts of plants simulation. The calibration of the machine vision system is a basic step for nondestructive detection. We discuss common methods such as traditional calibration techniques, active vision based calibration techniques, and self-calibration techniques. The results show that it is feasible to apply...
متن کاملCamera Modelling and Calibration with Machine Vision Applications
Camera Modelling and Calibration with Machine Vision Applications Anders Ryberg Department of Signals and Systems Chalmers University of Technology Camera modelling and calibration are important parts of machine vision. They can be used for calculating geometric information from images. A camera model is a mathematical projection between a 3D object space and a 2D image. The camera calibration ...
