Abstract
A steel plate surface quality online detection instrument comprises a rear end data base server and is characterized by being further provided with two linear array cameras with 4k-8k image resolution ratio, wherein the two linear array cameras are connected with a front end image processing server through a camera link data line and used for achieving image data transmission between the upper surface and the lower surface of a steel plate. The front end image processing server can process massive image data in real time and in multithreading mode, performs preprocessing, picking up and classifying defect images on the upper surface and the lower surface of the steel plate, and is connected with the rear end data base server through a kilomega network line so as to be used for transmitting the classified defect images to the rear end data base server. Two continuous light sources are further connected through a front end server and respectively provide luminance for the two linear array cameras. By using the high pixel and high-speed exposure characteristics of the linear array cameras, the steel plate surface quality online detection instrument can perform clear shooting on the steel plate in high-speed motion. In addition, the steel plate surface quality online detection instrument can adopt the continuous light sources with low manufacture cost, so that structure can be greatly simplified, cost is reduced, installation debugging period is shortened, and labor and time are saved.
Description
Technical field
The utility model relates to a kind of plate surface quality on-line detector based on the high-resolution linear array industrial camera.
Background technology
In steel and iron industry, because its industry characteristics, the automatization level of production is often than higher, and the production of various steel all is under supermatic equipment, to carry out, but the quality testing problem of this industry fails to obtain effectively solution always.It is a kind of very advanced thought that the method for utilizing machine vision is carried out quality monitoring to the production of iron and steel sheet and plate, has fully used the achievement of development in Hi-Tech, utilizes non-contact detection method that plate surface quality is carried out on-line real time monitoring.Plate surface quality carries out the on-line real time monitoring method and mainly comprises sorting technique of acquisition technology, image processing techniques, steel plate defect extractive technique, defect characteristic treatment technology and Surface Defects in Steel Plate etc.Need use a plurality of area array cameras in the past during IMAQ and must adopt high-power stroboscopic lamp, in addition, a plate card type computing machine was set behind each area array cameras.The plate surface quality on-line detector complex structure of this structure, cost height, the Installation and Debugging cycle is long, and artificial waste is big.
Summary of the invention
The technical matters that the utility model will solve provide a kind of simple in structure, cost is low, the Installation and Debugging cycle is short, the plate surface quality on-line detector of saving of work and time.
The technical solution of the utility model is:
It comprises back end database server; Its special character is: the line-scan digital camera that it also is provided with two image resolution ratios is 4k-8k; Line-scan digital camera links to each other with the front end image processing server through camera link data line; Be used for realizing steel plate upper and lower surfaces image data transmission, but handle the great amount of images data in real time, and steel plate upper and lower surfaces defect image is carried out pre-service, extraction, classification through front end image processing server multithreading; Described front end image processing server links to each other with back end database server through the gigabit netting twine, is used for classified defect image is transferred to back end database server; Also be connected to two continuous light sources through front-end server, two continuous light sources are respectively two line-scan digital cameras provides illumination.
Above-mentioned front end image processing server is that 8 tunnel 32 caryogamy are put.
The utility model adopts two industrial line-scan digital cameras to take the upper and lower surfaces image of high-speed motion steel plate respectively.Utilize the characteristics of the high pixel of line-scan digital camera, high-speed exposure, can take clearly, and can adopt the low continuous light source of cost the steel plate of high-speed motion.Simplified structure reduces cost greatly, shortens the Installation and Debugging cycle, saving of work and time.
