My generic question:
Given camera specifications, e.g:
- sensor resolution,
- sensor image area,
- pixel size (area),
- optical size,
- focal length (ratio),
- fov (horizontal and/or vertical)
and distance to an object to be view, how can i determine the smallest resolvable detail by this camera?
I am trying to build a detector for detecting defects in my products (plastic beads of about 3 mm). These defect have a range of sizes, on average they are about 100 micron but we would like to be able to detect 50 micron and up. These plastic beads will be falling down through a pipe and i will have the camera capture an image as it passes and use a processing step (based on color difference mostly) to find any defects on the bead. I want defects of size 50 micron and up to be resolved quite well, i.e. 50 micron defects have several tens to hundreds of pixels.
