Yaya za a sami Modulun Kamera na USB na Madaidai OS don Kiosk da Terminal
Sep 03, 2026
Kamera zai iya aiki da kyau a laptop na Windows na yin amfani kuma zai iya ƙaranta a cikin Android board da aka zauna don kiosk na baya. Masu sanyawa na terminal suna gano wannan bayan yanzu. Aljari na aljari ya nuna hoton 1080p mai kyau, don haka aiki na kameran zai dace da kammalawa. Amma a lokacin amfani da system, kameran zai ƙare ba tare da reboot, ko Android zai ba da mode na yawan resolusion, ko Linux zai sao video ba tare da ina iya canza exposure na application.
Sensor ba ta hanyar sababin kalmomi ba. A wadanda yawa, alƙalami yake a wani bangaren kamar firmware na kamera, UVC descriptors, USB bandwidth, camera stack na operating system, da application. Don project na terminal, bayyana Mudubu USB Camera yana kuma wani baya na farko. Alama ta yiwu a amfani da shi a cikin sistan na gina abinci kafin za a iya amfani da shi.
UVC ya rage ayyukan masu tsayarwa, amma ba ya cire amfani da tashin kamar yadda suka dace.
UVC yana nufin USB Video Class . Yana bayyana yadda alama na USB na foton ya bayyana hanyar saukin bayanai, hanyar saukin kudin, hanyar saukin rukuni, da hanyar saukin amfanin zuwa mai amfani. A Windows, alama mai dace na UVC zai iya amfani da alama na USB na foton na sistan kuma ba zai iya amfani da alama na kamera mai sauƙi. Wannan shine wani dalilin UVC alama suka kashe a kiosks, alama na kare kare, da alama na kungiyar.
Kuɗin amfani da sistan na gina zai iya canza natijen. Linux yana amfani da kamera na UVC ta hanyar uvcvideo driver da V4L2. Hanyoyin amfani na gina suna da kyau, amma hanyoyin amfani na masu gina zai iya buƙatar amfani da software na gina. Amfani da kamera na USB na gina na Android ya bukata karin tafiyar gaba: board din ya kamata ya da USB host mode, kernel din ya kamata ya shiga UVC, kuma system image din ya kamata ya cikin external camera provider ko application wanda ke zuba USB device ta hanyar direk. Bayanin mai bayani a matsayin wani module yana da amfani da Android ba za a iya amfani da shi don haka ba. Ya kamata a sanni amfani da shi a cikin board da system image na haɗa.
Mai amfani (Host) Ba Za Ya Iya Amfani da Yadda Mai Tsawo A Cikin Data Sheet Ba
Kunji Sinoseen OV2710 USB camera module . Wani bayani na shigarwa ya nuna 2 MP OV2710 sensor, 1920 x 1080 output, USB 2.0, fixed focus, kuma MJPEG da kuma yadda mai tsawo na YUV ba su da compression. Babu wani daga cikin wannan bayanan da aka nuna wanda ya sa hannu, amma mai amfani (host) ba za ya zuba yadda mai tsawo a cikin bayanin da aka nuna ba.
MJPEG yana ƙarƙashin 1080p ta zama ƙarƙashi don kawo ta USB 2.0 saboda ya rage kudin bus. Wani abu da ke cikin shirin shine yana bada gajeran aiki ga host. Wani processor na Android mai ƙarƙashin yana iya nuna ƙarƙashin 1080p yayi amfani da wani hiskullon CPU ta hanyar fassara. Kudin ƙarƙashin mara fassara ya canza wannan shirin: yana bukatar fassara ƙarƙashi amma yana ci gaba da kudin USB mai ƙarƙashin. Idan kameran ta share hub na farko da scanner na barcode, card reader, microphone, ko touchscreen, kudin wannan yana bukatar tattaunawa a lokacin farko. A baya amfani da module, rubutu ƙarƙashin, kudin frame, format, da kudin kwamfuta da aka bayyana da firmware na production ba tattaunawa da specification na sensor.
Kudin Fassara Mai Tsayi Ya Kamata Ya Kwafi Daga Layout na Terminal
OV2710 module yana amfani da mayar da hankali tare da filin gani na digiri 70. Ba tare da motar mayar da hankali don motsawa ba, sa, ko komawa cikin wuri mara kyau, mayar da hankali na dindindin sau da yawa zaɓi ne mai dogara ga tashar - idan dai nesa mai aiki ya kasance cikin kewayon sarrafawa. Wani kyamara a sama da nuni na iya buƙatar ɗaukar mai amfani daga 60 zuwa 100 cm. Wani akwatin ajiya mai kaifin baki yana iya bukatar ya ga mai amfani da kuma wurin da aka ajiye shi, yayin da wani na'urar ganowa na iya sanya takardar kusa da ruwan tabarau. Saitin mayar da hankali ɗaya ba zai dace da dukkan kayan aiki uku ba. Gwada kyamarar tare da ɗakin ƙarshe da gilashin rufewa. Idan ka kalli hoton da ke kan tebur, za ka ga cewa hoton yana da kyau sosai.
Tabbatar da Bayyanawa da Sauran Ayyukan Hotuna a Kowane OS
Takardar bayanai na iya lissafin haske, bambanci, jikewa, gamma, daidaiton fari, da sarrafawar fallasa, amma aikace-aikacen bazai iya amfani da kowane iko akan kowane tsarin aiki ba. Wani aikace-aikace na iya barin fallasa akan atomatik; wani na iya rubuta ƙimar ƙayyadaddun lokacin farawa. Wasu shirye-shirye suna sake saita saitunan kyamara bayan sake haɗa USB, yayin da wasu ke sake amfani da ƙimar da ta gabata. Za a iya ganin bambancin a tashar da aka saka kusa da ƙofar. Ƙofar haske na iya tura fuskar mai amfani cikin inuwa, kuma canji a cikin halayyar fallasa bayan sake farawa na iya canza aikin ganewa koda kuwa kayan aikin bai canza ba.
Ƙayyade wani amince kula saitin ga kowane aiki tsarin. Sannan maimaita irin wannan binciken bayan sanyi boot, dumi sake kunnawa, USB cirewa da sake haɗawa, da kuma sake kunna aikace-aikace. Kamara na iya yin aiki daban a kowace jiha; wucewa ɗaya daga cikinsu kawai baya kafa jituwa.
