    Abstract: 本論文,使用了原先幫助機器人做同時定位與地圖創建(Simultaneous Localization and Mapping ,SLAM)分析的裝置,它的名稱是UTM-30LX,因為它可以做即時的地圖建置,所以幫助人在周遭環境在看不清楚情形下,偵測周圍的活動範圍,再根據人和裝置間的相對位置,讓我們辨識出可以行走的方向和距離,本論文提出一個類似火場的情境,把生還者用一個箱子取代,放在角落,使得路徑長會變短,根據電腦接收裝置偵測到的數據做分析,看有沒有箱子擋住。

    關鍵詞 : 同時定位與地圖創建
    In this thesis, the use of the device was originally to help robots to do the analysis of SLAM (Simultaneous the Localization and Mapping), it calls the UTM-30LX, because it can be done to reconstruct the map immediately, so it can help people not to see clearly the situation in the surrounding environment , around the detection range of activities, according to these two relative positions configuring between people and device, let us identify the direction and distance of walking and therefore propose a similar fire situations, it replaces survivors by a group box,and put on the corner to make the path length becomes shorter,final the computer accepts the data which the device detects for analysis to see whether there is a box to block or not.
    At first We based on two scenarios for example,determine to how many positions place can reconstruct entire map , and then placed at a time, take the value of one block, configure these values by the way of the polar coordinates, and then convert the general 2-dimensional coordinate values plotted according to the actual scene placed in position between the length of the relative coordinate and original point, so we use a method to reconstruct a complete scene graph by puzzle.
    Obtain the complete scene graph, you can see that the length and coordinates of points between placement of each block.Next two chapters under such conditions, let the two scenes individually build a fire situation, corner of each scene put a box instead of survivors.
    Previous section, we use such law which compares path length and position of database,first reconstruct completely all from the entrance to corner of the path length , and then is based on placing in a box to produce the value of path length and location changes, insert the pre-reconstruct location of database correspond to the value of path length to replace the old one, compared with the original database to know where the location of the box to block, and then draw the new path length, and calculate the orientation and length of the path of the box, the information is transfer from the computer to the phone by wireless network to make testers do the actual scenario testing.
    Second chapter based on the previous chapter, it takes the shortcomings of the build time is too long to do improve, the first to write an algorithm to detect the obstacle in the three azimuth within 270 degree size, followed by the placement of a fixed distance, After detecting obstacle immediately , and drawn the path length and the position between the door and the obstacle, the information is also transferred from the computer to the phone by wireless network to make tester do the actual scenario testing , testers can be successfully found the box after the actual recording presented, due to spend time very different between the previous chapter and after the chapter,the entire build time of the previous chapter need to 3 hours ,and after the one need to 20 minutes, Based on the results of comparison, after the one applied to rescue and reconstruct in fire situation which is higher worth.
