The invention relates to an inclination plane scanning method based on two wind-measurement
laser radars, which comprises the steps of calculating the coordinates of wind-measurement
laser radars A, B and a target point C, and thus acquiring a unit normal vector p(u, v, w) of a plane in which the three points A, B, C are located; calculating attitude variables of the two wind-measurement
laser radars according to the vector p and a Euler formula, wherein the attitude variables comprise a
rolling angle, an
azimuth angle and a
pitch angle; thus adjusting the attitude of the two laser radars according to the three acquired attitude variables with the sequence being the
rolling angle, the
azimuth angle and the
pitch angle;
synchronizing the
system time of the two wind-measurement laser radars, and setting a
pitch angle, a scanning range and a scanning speed of a scanning rotating mirror; and enabling the two laser radars to operate simultaneously and perform
wind speed measurement. The inclination plane scanning method a problem of
data space mismatch of a traditional scanning method under the premise of not changing a
hardware structure of a wind-measurement laser
radar system, is simple to operate and easy to implement, truly gives play to advantages of the two wind-measurement laser radars in measurement for the
wind speed and the
wind direction, and thus improves the measurement accuracy.
