Machine Vision applications

The development of the machine vision during the last three decades has been amazingly large. Since the discovering and experimentation of the field, the application ofthe machine vision has become wide.

Car direction

There are numerous researches on the Japanese industry, for mentioning an example, on the development of a self controlled vehicle guided bycameras as told by Sadayuki Tsugawa, which may reduce the effect of traffic; actually on Japan are two well-known projects of machine vision to the car market, being them the, PVS and AHVS, while thefirst one was developed during the 1980’s by Nissan, the second one is being developed by Toyota.
The PVS is based on detecting lines on the road, having them a pattern to indicate the direction ofthe vehicle, making the captures of the camera from 5 to 25 meters ahead, this will detect the road lines, once they are captured, a vectorial transformation begins to indicate the direction for thecar. For turning the car, by meanings of the camera, a degree between the road line and the car is obtained.
Now if we look at the AHVS developed by Toyota, which is also oriented to detect the whitelines of the road by using a monochrome camera, but now detecting from 10 to 20 meters ahead, by using a template it compares the orientation of the line and instructs to follow.
The advantages ofthe development on the vehicular industries are above all kind of expectations, reducing traffic, accidents, energy saving and even environmental protections.
Tire industry inspection

On other kindsof applications, George Blackwell mentions about the developments on the tire industry, saying that there are three phases on the tire creation process where the machine vision may be ideal:non-contact measurement, process verification and process identification; all of those applications involve sensing an image by a camera, analyze it and communicate the results. By using the machine vision...
