Hello ,
I read that somewhere: the defect To be detected, and therefore visible in the image, must at least fit into a pixel. But it is sometimes necessary to use two or even four, because of the background or the environment. It remains to calculate the minimum definition (D) of the sensor thanks to the formula:
D = (field of view x Number of pixels for a defect) / size of the smallest detectable defect
my question how am I going to define the numbers of pixels for a default
PS: I am on a project of acquisition and image processing, for the acquisition and image processing on small distances of (5cm), and in order to detect a displacement (deformation) order of 1 micron on an image I would like to know what type of camera on resolution I have to choose sensor on a size marking (about 5X4 Cm), so I must calculet the resolution for the choice of my camera the best adapt thank you for your help ^^
