本文提出的測量車相機檢定(camera calibration)是解算相機的內方位元素、相機拍攝的像點系統性偏移向量、測量車上任意兩相機之間的相對方位,並且不使用檢定場而直接使用像點像坐標觀測值與各式物空間條件來解算。
本文的研究目標是匯集及設計出不利用檢定場而能夠應用於測量車(mobile mapping system)相機檢定之方法。利用環境中常見並且能夠使用的條件,如物空間(object space)距離、角度、已知點坐標等。聯合各種物空間條件進行光束法平差以求出相機檢定參數。
實驗結果顯示使用物空間條件檢定測量車相機參數是可行的,使用已知的三種方法─滅點幾何、兩滅點求解內方位元素、以及物空間三軸條件。這三種方法使用同樣的求解條件時(相同的滅點、影像上相同直線段端點像元)得到的相機內方位元素結果相同。本文結合各式物空間條件,如物空間中可用的已知線段長度、角度、物點共平面、垂直條件、水平條件、坐標差值、高程差、已知點位高程以及已知點位坐標等,求解相機檢定參數,並分析檢定成果與精度。本文以物空間已知條件(距離、水平與垂直條件、坐標差值)求解的內方位元素、外方位元素精度分別可達 0.008~0.010mm、 1~13公分、 0.052°~0.211°。

In this thesis, the camera calibration for a mobile mapping system (MMS) is to determine the interior orientation parameters, field of systematic bias vectors of image point positions, and the relative orientation of arbitrary two cameras on the MMS. Image coordinates of image points and diverse object space conditions are utilized to evaluate the aforementioned parameters without the need on calibration field.
This thesis utilizes four methods for the calibration of cameras on a MMS in which the calibration is done anywhere the MMS stays. The object space conditions such as the known distances, angles or coordinate differences are integrated with bundle adjustment to estimate the parameters of all cameras on a MMS.
Test results show that the proposed object-space-condition method is applicable for calibrating cameras of a MMS. The interior orientation parameters determined by three methods - three-vanishing-point method, two-vanishing-point method, and three-coordinate-axis method - are the same if they use the same set of image points inclusive of vanishing points and end points of vanishing lines. The object-space-condition method integrates different kinds of conditions (such as known lengths, angles, coordinate differences, coordinates, object heights as well as the perpendicular and parallel conditions) in object space to estimate the camera parameters by using the images taken by cameras on a mobile mapping system. The object space conditions adopted in all tests include known distances, coordinate differences, the parallel and perpendicular conditions, and are used to evaluate the precision of interior orientation elements and exterior orientation parameters defined in a local 3D coordinate system, which are about 0.008~0.010mm、 1~13cm、 0.052~0.211 degrees, respectively.
