Method and system for measuring lens quality |
摘要 |
A method for measuring lens quality includes receiving and transmitting an image's information to a location module through an image collecting module. A location module partitions the image's information into a plurality of measure areas. An image processing module computes the Modulation Transfer Function (MTF) of each measure area. A comparing module compares the MTF with a predetermined MTF to determine quality of the lenses. |
