Video Camera with Controlled Sensor Position for Physical Simulating Decalibration of Intrinsic Camera Parameters

During photogrammetric measurements, increased vibration, e.g. during in-flight tests, can affect the camera stereo system, which can lead to decalibration or change the actual values of its calibration parameters. This can lead to an increase in measurement errors. A physical simulation is proposed to investigate the effect of decalibration of internal parameters. It is based on a special video camera with the possibility of changing the position of the photosensitive sensor relative to the optical axis of the lens. In this work a quantitative experimental verification of the performance of the created prototype camera was carried out, the results of which confirmed the possibility of its use for further physical simulation.
