摘要本文设计的拍照式电脑采取STM32单片设施械当做主要处理设施，使OV7670摄像头模板收集的数字影响，传输至STM32单片设施械当做主控制芯片进行光学字符影像识别处理，并进行计算和记录；并将计算的过程和结果输出到LCD液晶显示屏上。最终能够获得一种高效率、高准确度、自动化的拍照式电脑。这种基于单片机的拍照式电脑，可以实现数值计算的全自动化，可以应用于手机上，代替原来的电脑。关键字影像识别；STM32单片机；自动化；高精确率I基于单片机的拍照式计算设施PHOTOCALCULATORBASEDONSINGLECHIPMICROCOMPUTERAbstractThephotocalculatordesignedinthispaperusesSTM32singlechipmicrocomputerasthecorecontroller.Thedigitalimagescollectedbyov7670cameramoduleareuploadedtoSTM32singlechipmicrocomputerasthemaincontrolchipforopticalcharacterimagerecognition,calculationandrecording;AndthecalculationprocessandresultsareoutputtotheLCDscreen.Finally,wecangetahighefficiency,highaccuracy,automaticphotocalculator.ThiskindofphotocalculatorbasedonMCUcanrealizethefullautomationofnumericalcalculation,andcanbeappliedtomobilephonestoreplacetheoriginalcalculator.KeywordsimagerecognitionSTM32microcontrollerautomationhighaccuracyII目录摘要........................................................................IAbstract...............................................................................................................................................................II1绪论..................................................................................................................................................................11.1研究背景及意义........................................................11.2发展历程..............................................................11.3研究拟解决的主要问题..................................................11.4设计说明书的行文安排..................................................22系统的设计方案...........................................................................................................................................32.1总体设计思路..........................................................32.2主要模块的设计原理....................................................32.2.1电源模块........................................................32.2.2单片机控制模块..................................................32.2.3摄像头模块......................................................42.2.4显示屏模块......................................................42.3其他重要元设施件..........................................................................................................................52.3.1电解电容........................................................52.5.2JZ晶振.........................................................52.5.3KEY按键........................................................63硬件电路的设计与实现..............................................................................................................................73.1单片机控制模块...............................................................................................................................73.1.1主控芯片........................................................73.1.2时钟电路........................................................73.1.3复位电路........................................................83.2摄像头模块............................................................83.3电源模块................
