A digital image - based ( dib ) technique was proposed to characterize and quantify the heterogeneity of rock , and it was implemented into rfpa ( rock failure process analysis ) code in order to simulate the complete failure process of rock under both the external loading and fluid pressure 本文提出了用数字图像处理技术表征岩石非均匀性的基本方法,并通过把该技术实施到岩石破裂过程分析程序rfpa中,来模拟非均匀岩石在外载荷和渗流耦合作用下发生破裂的整个过程。
First , the paper introduces the basic knowledge of the image processing technique , emphasizes the image processing method that is used in the measur - ement system , such as edge detection operator , curve fitting algorithm , espe - cially hough change in detail , etc . second , the paper introduces the vc + + 6 . 0 program language , analyses its peculiarity and advantage , explains the form of the image in the computer and dib visiting functions 首先,介绍了图像处理方法的基础知识,特别重点讲述了在本系统中将会应用到的一些图像处理方法,如边缘检测算子、曲线拟合算法等等,尤其是对于哈夫变换的方法,进行了详细阐述。其次,介绍了本系统所应用的编程语言vc + + 6 . 0 ,分析了其特点和优点,并说明了模拟图像数字化后,在计算机里的存储格式以及相应的设备无关位图访问函数。
Also we describe the principle , architecture and the recent development tendency of the cmos is . after discussing the structures and characters of many micro image processing systems , we pay attention to the software of the system . research on the programming structures and programming methods are the key contents of the paper , including how to capture video based on vfw how to play video based on mci and how to process images based on dib 本论文针对基于cmos图像传感器的显微图像系统,详细论述了cmos图像传感器的原理、构造及当前的发展状况,阐述了各种显微图像处理系统的构成和特点,并着重针对基于cmos图像传感器的显微图像系统的软件处理问题研究了程序结构和编程方法,就如何使用基于vfw的视频捕捉,基于mci的视频播放,基于dib的图像操作等给出了应用结果。
The main work completed in the paper is listed as following : 1 . image function acquisition - , 2 . read bmp files by dib format ; 3 . drawing gray scale histogram ; 4 . choose a optimum threshold and make gray image become binary image - , s . find image ' s contour points by making inner points become empty and apply template matching on the contour points ; 6 . transform the object ' s beginning points ( pixel point ) to the ones in the image coordinate and the positions of in the corresponding three dimensions ; 7 . compute the position vector and the normal vector of the object 选择一个最佳阕值,把灰度图像进行二值化处理; 5用掏空内部点法,找到图像的轮廓点,然后在轮廓点上进行模板匹配; 6把输出的目标物开始点(像素点)转化成图像坐标系中的点和对应的三维空间的坐标位置; 7计算目标物的位置矢量和法向矢量,根据机器人抓取面的法向矢量,找到机器人要抓取的平面; 8
In the last part , the whole course of the measurement is advanced . chapter three introduced some knowledge of digital image processing , including palette , grayscale and dib , but mainly talk about the structure of the bmp file . also we mainly introduced image transform method that we often use 第三步介绍了数字图像处理的基本知识,包括调色板,灰度图,设备无关位图( dib )等,并主要介绍了bmp文件的结构;以及图像处理中常用的一四川大学硕士论文些操作原理,例如滤波、二值化等等。
a claim of rights; "I have dibs on that last slice of pizza"
百科解释
Calling "dibs" is an informal convention where one declares a first claim to something to which no individual has any clearly recognized right. Calling "dibs" is only possible, when the caller is fit and able to take care of the claim.
