基于STM32的视频播放及图片识别系统的设计(任务书,开题报告,论文10400字)
摘要
现代社会科技高度发达，各类精密的电子元器件层出不穷，并且能在生活中扮演关键的角色，数字摄像头就是典型，由于它体积小重量轻，所以它的应用场景十分广泛，使得人类的生活更加便捷和趋向智能化，目前通过对二维码的识别而进行的移动支付就带给人们生活极大的便利。本文利用stm32单片机向OV5640摄像头写入各种配置参数，使得摄像头上捕捉到的图像可以顺利的在液晶屏上播放，在基础上，通过摄像头成像机制及ISP图像窗口的学习与了解，通过单片机向摄像头输入参数，更改其某些成像的配置，使其在成像之后可以使图像放大；之后就是利用利用单片机更改液晶屏的配置和对二维码编解码原理的学习，使得在屏幕上形成一个矩形框，矩形框内可以进行二维码的扫描与识别。

Design of Video Playback and Picture Recognition System Based on STM32
Abstract
Modern social science and technology are highly developed. Various kinds of sophisticated electronic components emerge in an endless stream and can play a key role in life. The digital camera is typical. Due to its small size and light weight, its application scenarios are very extensive, making human life more Convenient and tending to be intelligent, mobile payment through the recognition of two-dimensional codes has brought great convenience to people's lives. This article uses stm32 microcontroller to write a variety of configuration parameters to the OV5640 camera, so that the image captured on the camera can be successfully played on the LCD screen, on the basis, through the camera imaging mechanism and ISP image window learning and understanding, through the microcontroller Camera input parameters, change some of the imaging configuration, so that it can make the image after the image is enlarged; after that is to use the microcontroller to change the configuration of the LCD screen and the learning of the codec principle of the two-dimensional code, making a rectangle on the screen Box, rectangular box can be scanned and identified two-dimensional code.
