FEASIBILITY STUDY OF USING MOBILE PHONE CAMERA IN DIGITAL CLOSE RANGE PHOTOGRAMMETRY

The mobile industry has seen, in recent years, rapid developments which contain digital cameras with good resolution, this research study the possibility of use these cameras in a close range photogrammetry, which is widely used today in many engineering and scientific applications. This research has used two types of mobile phone with built-in digital cameras, the first type was NOKIA N82 and the second was CoolPAD 288. Stereo pair of digital photos have been picked up to the test field, which installed on it twenty four targets carefully, 3D- coordinates were observed by using Total Station instrument, type TOPCON-GPT7501. Because of non availability of External and Internal orientation elements of the camera, it used mathematical method known as Direct Linear Transformation DLT. The results obtained from using mobile phone camera in digital close range photogrammetry, were compared with field data, have showed that the Root Mean Square Error (RMSE), indicates promising results.
