The geometric calibration of time-of-flight range cameras is a necessary quality assurance measure performed to estimate the interior orientation parameters. Self-calibration from a network of range imagery of an array of signalized targets arranged in one or two planes can be used for this purpose. The use of action cameras for photogrammetry purposes is not widespread due to the fact that until recently the images provided by the sensors, using either still or video capture mode, were not big enough to perform and provide the appropriate analysis with the necessary photogrammetric accuracy. However, several manufacturers have recently produced and released new lightweight devices which Cited by: Dec 19, · The best cameras for under $ should have good ergonomics and controls, great image quality and be capture high-quality video. In this buying guide we’ve rounded up all the current interchangeable lens cameras costing under $ and recommended the best.

seems to be completely pointless. Furthermore it is known from experience with aerial survey film cameras, that self-calibration is required for practical applications because of systematic image deformation. This is as well true after a brand new camera calibration. For film cameras these effects are based on various influences like.
