I have built a fix mount on Y axis for my webcam with a custom ball joint for fine orientation along the Z axis. You can find a description here: http://blog.f1oat.org/tag/hd5000/ With this solution, I achieve an accuracy better than 0.05mm at 100mm height. I do not use automatic focus because it does not work well for edge finding: the autofocus is randomly on machine table or on top of workpiece. I use camview-emc with "ultil.crop" feature that is able to reduce the image resolution and make a digital zoom on the center. Optical zoom is better, but not available on my webcam. As a good side effect, as "util.crop" decreases the resolution, following image processing tasks are faster.
