Description: 微软的SQL SERVER数据库的Image、text等字段都属于二进制的大对象。这些对象的存取和其他轻型对象略有不同。
微软.NET Framework的System.IO命名空间下给我们提供了一个FileStream文件流类。我们可以使用这个文件流对二进制大对象轻松进行读写。
我实现了一个简单的WinForm程序，这个程序通过点击“Open”按钮选择一个bmp或者jpg文件，并显示在图形控件PictureBox中。通过“Save”按钮存入数据库。点击“View”CheckBox可以切换到浏览状态，观看存入数据库的图片。
由于对二进制大对象使用的流操作，所以对于任何文件都具有通用性。读写文本文件也可以这么做。
-Microsoft s field and so on SQL SERVER database Image, text all
belongs to binary the big object. These objects deposits and
withdrawals and other light objects have the difference slightly.
MicrosoftNET Framework System.Under the IO naming space provided a FileStream document to us to flow
the kind. We may use this document to flow to the binary big object
with ease carry on read-write. I have realized a simple WinForm
procedure, this procedure through clicks on \"Open\" the button to
choose bmp or the jpg document, and the demonstration controls in
PictureBox in the graph. The button stores the database through
\"Save\". Clicks on \"View\" CheckBox to be possible to cut to the
browsing condition, watches stores the database the picture. Because
to binary big object use class operation, therefore all has the
versatility regarding any document. The read-write text documents also
may such do. Platform: |

Description: 摘 要: video4 linux提供了一整套linux环境下操纵视频设备的函数接口,首先通过对video4 linux函数的调用成
功实现了两种方式(内存映射(mmap)和直接读取( read) )下摄像头数据的读取 然后对读取到内存缓冲区中的
RGB数据流进行分析,实现了同时对两种特定颜色(红、绿、蓝等)的识别,并给出相应色块的端点坐标 最后通过
对特定颜色箭头的端点分析,识别了箭头指向的角度 为了便于调试程序和验证结果,分析完成后把缓冲区中的
RGB流保存为BMP文件。-Abstract: video4 linux environment to provide a set of linux video equipment under the control of the function interface, the first function of the call video4 linux successfully in two ways (memory mapping (mmap) and direct reading (read)) under the camera data read then read into memory buffer of RGB data flow analysis, achieved at the same time for two specific colors (red, green, blue, etc.) to identify, and give the corresponding color coordinates of the endpoint final arrow on the specific color of the endpoint analysis, identification of the arrow point to the point of view In order to facilitate the debugging process and to verify the results of analysis after the completion of the RGB buffer to save it as a BMP file stream.

Description: 本程序实现了对影像特征点自动提取，利用Morevac、Forstner、Harris3个经典算子。在此基础上利用相关系数法实现影像自动匹配，并且引入最小二乘平差，使匹配点精度有所提高。
在搜索点过程中，利用了核线影像特性，对二维影像搜索使用了爬山法启发式搜索。对大数据量影像采用影像金字塔结构处理。
1、使用GDAL库读取影片，支持TIFF、PNG、JPEG、JPG、BMP、GIF、IMG格式读取。使用GDI绘图。
2、防止大数据量绘图视图闪烁，图片显示采用双缓存技术。
3、保存视图数据为图片文件，支持TIFF、PNG、JPEG、JPG、BMP、GIF格式保存。
4、TreeCtrl控件、ListCtrl控件的基本操作。
5、MFC单文档程序视图通讯、更换视图、视图分割。-This program of image features automatic extraction point, use Morevac, Forstner, Harris3 a classic operator. Based on the correlation coefficient method using the image matching, realization and introducing least squares adjustment, the matching point to improve precision.
In the search process, the use of the image characteristics of nuclear line, 2d image search using the heuristic method of climbing. For large quantity of data using image processing image pyramid structure.
1, using film, read GDAL repository support JPEG, TIFF, PNG, GIF, BMP, JPG, read IMG format. Use GDI drawing.
2 and prevent large amount of data, drawing view pictures showed adopt double caching techniques.
3, save for the image file, views data support JPEG, TIFF, JPG, PNG, GIF, BMP format.
4 and TreeCtrl controls, the basic operation ListCtrl controls.
5 and MFC single document procedure view communication, replace view, view. Platform: |
