I am new to the field of cameras and imaging. I am working with an industrial camera.
I need to check if the camera captured sufficient detail in the image and whether the images are good enough to be used for further analysis. What I came across while searching on the internet is spatial resolution.
After doing some experiments with image capture, what I learned is that if I capture the zoomed-in image, then spatial resolution increases. Is this correct? What factors determine this value? Is spatial resolution limited by the camera sensor and lens specifications? Or does it have to do with the way an image is captured? Will the spatial resolution change if I capture an image from an angle? Do focussing range and aperture affect the spatial resolution? Is spatial resolution the only thing that I should look for?
I am calculating the spatial resolution by getting the number of pixels covering 1mm of area in the image.
