Based on The Isual Component Size Measurement
Parts size measuring based on vision is the main research is to simulate human visual
function to process the image to extract information from the objective things to understand,
eventually acquire data needed for the actual size. In recent years, based on the visual
component size measurement technology in the field of measurement in recent years the rapid
development of new technology. It is based on the modern optics, the integration of computer,
laser technology, image processing and analysis technology such as modern science and
technology is a body comprehensive measuring technique.
In this paper, we use part size measurement based on visual method to measure the
mechanical parts of 2 d geometry, through image processing and Matlab programming drawing
two-dimensional curve analysis of mechanical parts processing. Emphatically study the key
technology in the process of image processing and system calibration problems, achieve
sub-pixel locating on the edge of mechanical parts size, further realize high precision of
component size.Parts size measuring based on vision application in part size measurement is
discussed in detail, and focuses on the process of image processing method, through the Matlab
calculation and two-dimensional image rendering, parts size online measuring system based on
vision is achieved. The main research content below:
1.Introduce the basic concept of topic, the research background and significance of the
development and the existing problems at home and abroad, clear solutions to this topic, this
paper based on the visual parts dimension measurement technology, the technology of online
measurement scheme wake the theoretical analysis and experimental verification, to prove the
feasibility of it
2.Analysis of image calibration technology, the use of standard calibration method and the
whole measurement system calibration, data obtained through the experiment to verify the
accuracy of measurement system.
3.Through the analysis of the image processing algorithm, using Matlab, the realization of
image preprocessing and pixel edge detection.In-depth analysis of the image data processing
and the subpixel edge location technology, improve the calculation speed and calculation
accuracy.
