Device for fast movement restitution by observation of a reflecting pattern and method for the realisation of the device

摘要

This device consists of at least one test pattern (14), a video camera (20) and a flashlamp (22) synchronised with the shots of the camera (20) by a triggering circuit (24). An electronic unit (26) for processing the video signal provides for analog-digital conversion, compression and encoding of the video signal. The encoded video signal is sent by a transmitting circuit (28) to circuits (30) for the analysis, processing and display of the transmitted encoded signal. The signal compression involves extracting the contours of the images recorded by the camera (20). Application to the reconstruction of the movement of a body (10) released from a booster rocket (12). IMAGE
