Helicopter Photogrammetry Algorithm To Guide The Laser Monitoring Experiments

The common guiding and landing methods of helicopters is discussed in this dissertation. We studied the CCD-photogrammetry that will be used in the landing of helicopter to measure the precise position. We made the model of using the four signal dot to measure the position of the probe of the helicopter. The factors which will affect on the maxim angle and error of CCD-photogrammetry is discussed.The outcome of computing show that if we select appropriate paraments of CCD we can control the error of measure in five centimeters.The highpass filter we will be used to process the picture is emulatored on the computer. The outcome has shown that the method of highpass filter can pick up the signal well. The scaning laser is use to measure the range of helicopter and guid it returning miles away. The interface of singlechip and computer is designed to measure data automatically.This method is brought forward in the first time. We establish a suit of slass system emulating experiment which emulated the signal that reflected from the angle-reflecting mirror.The experiment supply the important base for the further real system that we will build and it has important value.
