Agreed, its essentially useless for what I want to do. Way too wide a
field of view. I need an endoscope sized camera with a long lens and a
very narrow F.O.V. for mounting on a milling machine head for a video
edge finder. For this app, it needs focusing, or at least mechanically
adjustable to something in the 50mm range as it must be mounted high
enough to clear fixture bolts holding down the work. Cameras which
encounter those bolts are destroyed like so much velveta cheese
We have software, capable of rotating our co-ordinate systems to make a
mounted part which may not be mounted in perfect x/y alignment into
perfection for the milling machine but it needs tlc, in that if the
image is expanded until the cameras image touches the edge of the
allocated window, the image goes away and the computer must be rebooted
to restore its function. Since that occurs as the LinuxCNC "axis"
control window is expanded and before it reaches full screen, its a
right pain in the ass to try and use.
Does a review, with an eye toward this kind of use exist?
