hul 2004 O L30 3 PERFORMANCE EVALUATION BY OUTDOOR EXPERIMENT In order to evaluate more practical accuracy, experiment was performed at outdoor using following 4 card size digital cameras and armature digital camera (CP-900Z). 17 targets were set on the test field which shown in figure 8. Circled 9 points were used for camera calibration, and other 8 points were used as check points. 3D coordinates of each target are measured by the total station (Accuracy of distance is Imm, accuracy of angle is 2” ), and image coordinate were given as center of area gravity by image processing procedures. Stereo images were taken 5 times using the 5 cameras so that base-height ration (0.34) might become the same condition (distance from the center of camera to test field (H:23.617m), and base line(B:8.029m)).

Model 1 means the results which were corrected by radial polynomial 3rd degrees distortion model, model 3 means by radial and tangential model, theoretical values means computed values using Eqs. (1) as pointing accuracy for each camera was assumed 0.3 pixel. It may be said from this results that lens distortion for the card size digital cameras can be improved by radial and tangential International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, Vol XXXV, Part B-YF. Istanbul 2004 distortion model as well as experiment on the above-mentioned, in particular XY accuracy is considerably improved by model 3. The accuracy for the card size digital cameras which were corrected by Modl 3 showed almost same accuracy compare with CP-900Z which were corrected by model 1. Furthermore, the accuracy for the card size digital cameras which were corrected by Modl 3 showed almost same accuracy compare with theoretical accuracy. Consequently, it can be concluded that card size digital cameras are ushering in photogrammetric fields as an essential tool, which have ability to promise convenient photogrammetry 4 CONCLUSIONS Performance evaluation of the card size digital cameras for digital photogrammetry were investigated. XY accuracy is considerably improved by radial and tangential distortion model (model 3), and lens distortion for the card size digital cameras can be improved by model 3. Nevertheless lens distortion for armature digital camera with more than 3 mega pixels can be improved by radial polynomial 3rd degree distortion model as usual. On the other hand, from the results of the relationship with accuracy and pixel numbers, it can be seen that accuracy for the card size digital cameras which were corrected by model 3 shows almost same value with high resolution armature digital cameras with more than 3 mega pixels and professional digital cameras with 6 mega pixels Furthermore, the accuracy for the card size digital cameras which were corrected by Model 3 showed almost same accuracy compare with CP-900Z which were corrected by model 1 and with theoretical accuracy. Consequently, it is expected that card size digital cameras are popularly used in photogrammetric fields as a essential tool which have ability to progress convenient photogrammetry.
