  1. The research about the non - invasive inspection of pcb that is based on ir image is introduced. the detection principle, the components of hardware and software are introduced in this paper. some key technical problems and the project of software are presented in detail : graphics of user interface ( gui ) of the projection, gray scale transformation ( gst ), image contour extraction through edge detection algorithm based on the approaching contour optimization, image registration based on corner detection, the position of hidden trouble pcb through add - minus algorithm image

    本文介紹了利用紅外圖像對印製電路板進行不接觸式故障檢測的系統研究，主要介紹了本系統的檢測原理，硬體組成及軟體的製作，其中詳細地介紹了軟體的製作過程以及其中的幾個關鍵部分：本系統的人機交互界面；圖像的灰度轉換；基於最優輪廓逼近的邊緣提取演算法進行輪廓提取；基於角點檢測的圖像配準；用差影法得到故障電路板的故障隱患或故障部位。
  2. In third chapter author uses this ability to detect the edge of image. author hopes to detect pcb defection based on this method. the experiments testify validity of this method

    實驗證明，利用小波變換具有檢測信號突變點及多尺度分析的能力來進行缺陷圖像邊緣檢測是有效的。
  3. Edge clearance : the smallest distance from any conductors or components to the edge of the pcb

    邊安全間距：導線或元件到pcb邊的最小間距。
