Abstract

Manual focus is general adapted in the traditional hardness tester, while the manual focus depends much on the tester, and the precision of the manual varies from tester to tester. Based on the basic principle of image processing of automatic focus, this paper presents auto-focus system applying a chip of STM32F407 as the host controller of hardness tester. Through the test, the system can get the focus position efficiently, and the accuracy is guaranteed.
