| Summary: | Today many photogrammetric works involved the use of digital cameras due to it's in low cost. Digital camera has been used in many photogrammetric applications such as archaeology, architecture, accident investigation, cultural heritage and etc. Theoretically, most digital camera is known as non-metric camera where the interior geometrical of digital camera is not stable, however, the optical quality is not acceptable. The need for camera calibration has been fundamental requirement for obtaining accurate measurement since the inception of photogrammetry. This study deals with the acquisition and processing of different configuration of digital camera (convergent and generic network) which are position at different height versus different digital camera setup. The accuracy assessment was performed for two high resolution digital cameras which are Nikon D90 and Rollei D30metric5 digital cameras. The height of digital camera is setup at approximately 80cm and 100cm. Finally, this study evaluates the accuracy of the camera calibration based on standard deviation of interior camera calibration parameters. This study shows that high resolution Nikon D90 digital camera which is categorized as low cost could be used in photogrammetric application with good accuracy achievable. |
