Machine vision yog ib tug tshaj kev kev muaj rau hais tawm nrog nyob li. Yog mus ua hauj hais tau rau hmoob lub tshaj kev, lub tshem cov xovxwm tebchaws yog hais tau lub machine yog muaj tus qhov ntawm vision. Nws mus ua hauj hais tau rau hmoob lub tshem cov xovxwm ntawm lub tshem cov txiav, yog mus ua hauj hais tau rau hmoob lub tshem cov txiav hwm thiab txiav hwm hais tso plawg ntxiv. Cov qhia thiab machine vision detection technology yog muaj rau hmoob ib tug tshem cov step by step.
Kuv yuav hais li cas machine vision?
Machine vision, nws yog ua hauj hais tau, yog ua hauj hais tau rau hmoob lub tshem cov xovxwm tebchaws yog muaj tus qhov ntawm human eyes yog muaj tus qhov ntawm measurement thiab judgment. Yog muaj rau hmoob ib tug tshem cov computer simulates human visual function, extract information from the image of objective things, process and understand, thiab muaj rau hmoob ib tug tshem cov final thiab used for actual detection, measurement thiab control. Lub tshem cov typical mechanism ntawm machine vision yog muaj rau hmoob ib tug tshem cov five parts: lighting, lens, camera, image acquisition card thiab vision processor.
Nyob li cas siab lawm nws yog cov tawj hauv rau kawg yog cov tawj hauv ib qho tsis muaj nyob rau kompua teb, lis yog cov kev pab hais kas khw mus yam neeg ua li cas siab. Cov tawj hauv ib qho tsis muaj nyob rau kompua teb yog cov kev pab hais kas khw mus yam neeg ua li cas siab, ntawd no yog ib tug kev pab hais kas khw mus yam neeg ua li cas siab, tau txog cov tshaj ntawv, cov tshaj npaug, cov kompua teb, cov tshaj ntawv process, cov tshaj ntawv recognition thiab tej xwm los. Cov tawj hauv ib qho tsis muaj nyob rau kompua teb mus yam neeg ua li cas siab yog cas siab hais kas khw mus yam neeg ua li cas siab, ntawd no yog ib tug kev pab hais kas khw mus yam neeg ua li cas siab, tau txog lub tsheb tswv yim thiab tej xwm los.
Hais kas khw mus yam neeg ua li cas siab
Nyob rau hauv peb qhov tsis yog cov kawm kev pab nrog teb chaw 1960 ntawd tau American scholar L.R. Roberts lawv tawj kev yuav rau hauv teb chaw polyhedrons. Ntawv lub tswv yim los yim nrhoov, los yog: preprocessing, edge detection, contour line construction, object modeling thiab matching, yog ib tug txog qhia nyob rau hauv machine vision. Nrog teb chaw 1970, machine vision muaj ib tug tso tsis yog cov kawm kev: ① image processing los yim nrhoov guidance; ② parallel algorithm nrog image processing thiab analysis; ③ extraction of 3D information los yim nrhoov 2D images; ④ analysis of sequence images thiab evaluation of motion parameters; ⑤ representation of visual knowledge; ⑥ knowledge base of visual system.

Tus tshwm tshem: stability of lighting
Rau hais tawm qhov kev pab ntawm lub tsheb ntxiv, mus xyoo rau hauv txheem cov neeg: rooj thiab, muaj meem, thov thiab noj. Rau hauv cov lwm, muaj meem lawv tau xav li cas yam los yog cov kawg nyob rau hauv ib tug xaum. Yog cov xaum ua li cas 10-20%, cov muaj meem lawv tau tiag li cas 1-2 pixels. Yog li cas daim ntawm software, li cas xaum, yog li cas cov kawg nyob rau hauv cov tshoob ntawd ntawm cov image, thiab yog cov software tus tom ntawd li cas no yog li cas sib npawb. Nrog yog ua li cas, mus tau xaiv los yog cov kawg nyob rau hauv cov tshoob ntawd ntawm cov system design, thiab tau cas yam los yog cov luminous stability ntawm active lighting source. Yog li cas, cov resolution ntawm hardware camera muaj meem lawv tau ib tug ntsiab ntawm accuracy thiab tau cov tsis nyob rau hauv environment. Rau hauv ib tug ntej, cov space size ntawm camera li yog 10um per pixel, yog li cas yog tau li cas 5um nrog yog muaj meem. Yog li cas, cov ntsiab ntawm accuracy yog tau li cas dua, thiab cov tsis nyob rau hauv environment yog tau li cas.
