Focus self-calibration for a digital camera may be performed by moving a lens assembly of the digital camera over its travel range, and detecting travel limits of the lens assembly based on audio signal generated by the lens assembly reaching ends of the travel range. Digital-to-analog ...
Over the 25 years since the introduction of analytical camera self-calibration there has been a revolution in close-range photogrammetric image acquisition systems. High-resolution, large-area [`]digital' CCD sensors have all but replaced film cameras. Throughout the period of this transition, self...
Before use of non-metric digital camera in photogrammetry,camera calibration is an essential step,whose accuracy determines directly the accuracy of mapping.Compared with other methods,the camera calibration based on calibration field can reflect the physical state of camera in work,and find new system...

The question that must be asked is what effect do these temperature changes have on the camera geometry? Sometimes the application allows sufficient image geometry for a selfcalibration, sometimes not. Should the cameras be allowed to acclimatise? A number of questions can be raised related to ...

With this aim, ICC is developing a project to obtain genuine colours in the photographic products produced with the DMC camera and this paper contains some preliminary results. Since an absolute radiometric calibration of the DMC is not available yet, this is accomplished through simultaneous images...
