Analysis and Test of the Exposure Synchronization of the Multi-Sensor Aerial Photogrammetric Camera System

Detailed analysis of exposure synchronization is made aiming at high precision matching and combining the images captured by multi sensor camera system. Exposure mechanism and motion of shutter blades or curtains become the main source of asynchronic error among individual cameras. Two methods are used to test the exposure asynchronization according to both between lens shutter and focal plane shutter configurations. Analysis of the results shows the consistency of theoretical analysis and test measurements.
