Antenna attitude fast measurement system and method thereof

An antenna attitude fast measurement system, comprising a data processing unit, a stereo calibration unit, at least four detector measurement units, and a plurality of target marker units;

• the target marker units are arranged on a back of an antenna main reflector of an antenna system to be measured, and move together with the antenna system to be measured;
• the detector measurement units are arranged outside a circumference of the antenna system to be measured, and a camera network composed of the plurality of detector measurement units is used for real-time monitoring of positions of the target marker units;
• and the stereo calibration unit is arranged directly below a center of the antenna main reflector and is used to calibrate the detector measurement units;
• wherein a distribution of the detector measurement units is determined based on a rotation attitude of the antenna system to be measured, and a number of the detector measurement units is determined based on an aperture and the rotation amplitude of the antenna system to be measured;
• wherein a field-of-view of each of the detector measurement units covers the stereo calibration unit and some of the target marker units, as well as a motion range of some of the target marker units;
• any two adjacent detector measurement units of the at least four detector measurement units have field-of-view intersection areas, such that there is at least one of the target marker units within each of the field-of-view intersection areas, and a total number of the target marker units within all of the field-of-view intersection areas is equal to or greater than 3;
• wherein the data processing unit is electrically connected to the detector measurement units and is used to receive and process images taken by the detector measurement units, obtain spatial three-dimensional coordinates of the target marker units based on a base point of the stereo calibration unit, and fit the three-dimensional coordinates based on a theoretical surface to obtain attitude information of the antenna system to be measured.
