  3. The main works are as following : 1. in view of the large quantity of data obtained from optical measurement equipments, we put forward the idea of mass data process system framework, which is data realm division first and then block data compression according it, we establish conceptual framework base on that, and design system structure, data stream

    主要工作如下: 1 、針對光學測量設備得到的測量數據具有數據量巨大的特點，本文提出了先採用數據區域劃分，再對各劃分后的數據按區域壓縮的海量數據處理系統框架設計思路，建立了總體框架，設計了系統結構、數據流。
  4. In view of above problems, this article studies the key technology of mass data processing system, and design a system framework point to the triangle mesh data, which is made up of millions series of triangles. this framework resolves the problem that a computer could not read all the mass data into its storage and process them through data block partion, and also reduces the space that mass data occupies in hd by data compression

    針對以上問題，本文研究了海量數據處理系統的關鍵技術，針對由百萬級數量的三角形構成的三角網格數據，設計了一個系統框架，通過數據分塊解決計算機不能把海量數據全部讀入內存進行處理的問題，通過數據壓縮解決海量數據佔用大量硬盤空間的問題。
  5. One of the common characters between traditional algorithms based on dct image coding is that regardless of the content of the image, they use a fixed size block to process, for example, jpeg, mpeg - 1 / 2, h. 263 use constant 8 * 8 block mode. the main work of this article is to propose a sequence images compression algorithm that is based on adaptive block dividing and object to the disadvantages of the one based on fixed - size block dividing. the proposed algorithm is an image compression method, which can auto - adjust dct block size ( 8 * 8 or 4 * 4 ) according to the difference of corresponding blocks between two frames of the sequential image and doesn ’ t process any unnecessary data blocks in order to enhance coding efficiency

    傳統的基於dct的圖像編碼演算法的一個共同特點就是:不管圖像的具體內容，採用固定的塊尺寸進行統一的處理，例如jpeg ， mpeg - 1 / 2 ， h . 263均採用固定的8 8分塊方式，本文的重點工作是針對這些採用固定的塊尺寸進行統一處理的演算法的一些缺點，提出了一種基於自適應分塊的序列圖像壓縮演算法，該演算法是一種根據序列圖像兩幀間對應塊的差別自動調整dct變換尺寸（ 8 8或4 4 ） ，對不必要的數據塊不進行處理，以提高編碼效率的序列圖像壓縮編碼方法，具有較高的編碼效率和較好的壓縮效果，與傳統的採用8 8固定分塊方式的壓縮編碼演算法相比，性能有較大幅度的提高，在文中，作者對兩者的壓縮編碼性能進行了分析比較。
