Although there have been many application instances in the field of input / output device technology, we need an specific project and technology route aimed at an given application. in this thesis, we combine the introduction and analysis of relative technology to describe the accomplishment of a coordinate collecting device which is based on incremental rotary encoder. this device is an specific device applied to collect the corrdinate displacement of ground image ’ s three - dimensional model created by full digital photogrammetric station. cpld chip and vhdl are applied in this device to carry out the following work : phase control of the electrical pulse created by incremental rotary encoder, counting the number of electrical pulse, controling the state of signal processing circuit, exchanging data between this circuit and pci control
本文結合相關技術的介紹和分析，描述了一個基於增量式旋轉編碼器的坐標參量採集介面卡的實現，此介面卡是一種用於採集全數字攝影測量系統地面影像模型坐標位移量的專用設備，該設備採用cpld器件和vhdl語言實現增量式旋轉編碼器的脈沖信號鑒相和計數、信號處理部分的狀態控制以及和pci總線晶元ch365之間的數據交換和通信功能，同時該設備的驅動程序基於wdm模式，並且配置有結構良好的動態鏈接庫程序作為系統軟體和驅動程序之間的數據和控制交互中間介面，能夠方便地運行在windows98 / 2000 / xp操作系統平臺上，具有實時性強、工作穩定、通用性較好和性價比高等特點。We have researched and exploited the highway engineering project management information system ( acronyms : hepmis ) based on gis for resolution of the former problem. we take advantage of the digital method to deal with the construction management of highway and cost and the progress control in researching and exploiting the hepmis. the intension of the hepmis is to handle all kinds of information about highway with visual virtual ( model ) method, and let these information reappear computer terminal for dynamic management
公路工程項目管理信息系統的研究與開發是用數字的方法處理公路的施工管理、費用及進度控制等方面和環節，其內涵是將公路的各種信息用可視化的虛擬（模型）方式，再現在計算機終端而進行動態管理，使「摸不著、看不見」和「看得見、摸得著」的信息，用數字的方式輸入到計算機系統之中，最終顯示出來，供公路施工管理使用。The paper discusses how to design the chinese character and word code to meet the various input modes at first, then designs a dynamic self - study language model, and analyses the data smoothing algorithm in the language model
文章首先討論了怎樣設計字詞碼本結構，使之能夠滿足靈活多樣的輸入方式，繼而設計了一種動態自學習語言模型，重點分析了數據平滑演算法在語言模型中的應用與改進，最後通過一個輸入法示常式序，對改進前後不同情況下的輸入效果進行了測試。The ecological footprint has been given much attention as an indicator for urban sustainable development over the last years. this paper applies the ef concept and calculation method to measure the ecological sustainability of shenzhen city in 2000
在介紹生態足跡的理論和計算模型的基礎之上，對深圳市2000年的生態可持續發展狀態進行了實例計算和分析，結果表明深圳市2000年的人均生態赤字為1 . 9751hmThe paper is based on the project of " the research of mathematics and computer frequency dynamic simulation theory on knobs not result ". the research content is object to the image of log knobs by vidicon getting to detect the shape of log knobs according to the method of video disposal. the paper apply digital image processing technology to log knobs image to swell and detect borders, then distill the surface shape and characteristic parameter of knobs. the thesis depict the knobs three - dimensional models, build the mathematics models of log knobs and simulation two - dimensional image curve of the log knobs primary section which has been discerned, thereby achieve our researching aim to reappear the knobs image on computer
本論文是國家自然科學基金資助項目「節子ndt結果的數學描述與視頻動態模擬理論的研究」的基礎研究之一，論文的研究內容是通過視頻處理的方法檢測原木表面節子的形狀，以攝像機採集的原木表面節子圖像為對象，運用數字圖像處理技術對節子圖像進行修正、增強、邊緣檢測等處理，提取節子的形狀特徵參數，並運用數學的方法，歸納總結其規律，應用數學的方法對節子的二維模型進行描述，建立原木節子的數學模型，對識別出的原木節子主截面的三維圖像曲線進行擬合處理，從而在計算機上實現節子的分佈與形態的再現，達到研究節子的空間形態和分佈規律的目的。The ability to work over recursively defined types of objects is one of the most salient characteristics of software engineering as opposed to, say, digital design, where the systems are built from finite - state machines
