Abstract

We present a real-time error-compensation method which is used to improve the measurement precision of a Scheimpflug range sensor. Based on this method a Scheimpflug range sensor is fabricated. It only takes 3.21 ms to complete one distance measurement in a hardware test. Furthermore, by using this range sensor, an altitude-holding application is performed on a proof-of-concept flight test platform in the lab environment. The hardware-in-loop (HIL) simulation result shows that approximately 10 mm control accuracy is achieved by implementing the error compensation.
