The ccd-80 series scanner is an ergonomic design hand-held bar code reading and decoding device . it reads label on any flat, curved or irregular surface ccd-80掃描器系列具有良好的人體工學(xué)設(shè)計和良好的解碼器,他可以閱讀在任何材質(zhì)平面上的條碼或是彎曲或是印刷于不平的表面的條碼。
Firstly, the system is divided into many modules according to different point of view; secondly, to the hardware equipment-vidicon, lenses, revolver, shield and decode device, their principle of work has been explained; thirdly, according to image identification experience and other indexes of the system, the focus of the lenses and relative aperture are calculated, and the type of the camera is confirmed, at the same time, the energy of infrared lamp is also computed in the thesis; at the same time, synthesis control box is devised 首先,按照角度的不同,將系統(tǒng)劃分成許多模塊。其次,對硬件設(shè)備??攝像機,鏡頭,云臺,防護罩,解碼器等的工作原理進行了闡述,再次,以人的成像辨認的經(jīng)驗判據(jù)為依據(jù),結(jié)合系統(tǒng)的其它指標,設(shè)計計算出鏡頭的焦距f、相對孔徑d,同時確定攝像機的型號,并計算出紅外燈光源。最后,對綜合控制箱進行設(shè)計,指出了設(shè)計的意義,實現(xiàn)的功能,并附上了綜合控制箱的外形圖。
In the hardware design aspect, a set of active infrared monitoring is designed, which includes the infrared lamp, the lens, vidicon, digital image collection and processing, the signal transmission and control, revolver, shield, decode device, the design of the synthesis controlling box and the model selecting 在硬件實現(xiàn)方面,設(shè)計完成了一套主動紅外成像監(jiān)控裝置的硬件設(shè)備,包括紅外燈、鏡頭、攝像機、數(shù)字圖像采集與處理、信號的傳輸與控制、云臺、防護罩、解碼器以及綜合控制箱的設(shè)計與選型。
