Description
Technical field
The utility model is related to a kind of fluid media (medium) automatic identification equipment, is to utilize imaging device, with reference to peace exactly
The viewing mirror of industrial pipeline of dress, to the fluid media (medium) in pipeline automated imaging, image process and analysis are carried out, and are automatically performed to flowing through
The identification of fluids within pipes.
Background technology
Machine vision technique is a kind of young, new industry technology, and the visual performance of human eye is used instead at present, its
System architecture is by photoelectric imaging device and is provided with the microcomputer of vision software and constitutes, mainly have three kinds of forms, i.e. industrial camera,
Smart camera, vision sensor, its machine body has communication function, carries out with the solid matter to definite shape and volume
Automatic sizing, inspection, guiding, identification.
Industrial camera includes camera, camera lens, light source and light source controller, and the device does not have image process and analysis work(
Can, it exports the image of shooting on the microcomputer equipped with vision software, image procossing is carried out to image by microcomputer and is divided
Analysis；Smart camera and vision sensor are embedded systems, are the special-purpose computers designed for image process and analysis application
System, the machine has image process and analysis function.Smart camera image process and analysis ability is higher, for high requirement
Application scenario；Vision sensor collection IMAQ, light source, camera lens, image procossing are controlled in one, are such as used for with/without detection
Etc. the simple occasion of application requirement.
