Design Of Several Industrial Camera Based On Machine Vision

Industrial Lens is commonly known as the photographic lens or camera lens, referred to as the lens. The lens is an important part of machine vision system, it plays a decisive role in the imaging quality. It is widely used in security monitoring, intelligent assembly, inspection and measurement and other industrial aspects. A lens from design to production test is very complicated, each step must be done very well and last finished lens can be adapt to complex industrial applications and field environmental. The paper is aimed at the optical design and about research design used in the different aspects of industrial lens. The main contents of this paper include:1. The design of a wide range of machine vision system solves the problem the automatic assembly line work distance is flexible. It is based on the theory change of the location of the object surface impacts on the system primary aberration to finally get lens with the focusing range from160mm to infinity and mega pixels.2. Design an object-side telecentric optical system, it has a constant magnification and angle to use in machine vision measuring system, and overcome the measurement error results of measured object image defocus and suitable for the measurement of surface is not coincidence or axial dynamic analyte.3. Design two high-definitions day and night monitoring optical system. The one is short focal, large field day and night monitoring camera lens with mega pixels and the total length without30mm and its field of view is more than90°for shops monitoring theft; The other one is traffic day and night surveillance camera, its total length does not exceed60mm and the resolution achieves5mega pixels. To meet the needs of the high-definition day and night lens in the security monitoring market...
