Abstract
The present invention discloses an optimal configuration method for positioning a target point by using five to seven beacon points. The present invention comprises two parts, wherein the first part is respectively giving a target point and an optimal measurement configuration of five to seven beacon points; and the second part is when respectively the target point is given and the optimal measurement configuration is adopted by the five to seven beacon points, configuring an influence coefficient on coordinate precision of the target point. According to the optimal configuration method for positioning the target point by using five to seven beacon points provided by the present invention, an optimal solution of a spatial coordinate of the target point can be obtained by adopting the optimal measurement configuration, and using a coordinate of a beacon point and a distance between the target point and the beacon point.
Description
technical field [0001] The invention relates to the field of wind tunnel testing, in particular to an optimal configuration method for locating target points with five to seven beacon points. Background technique [0002] The method of determining the position of a point (target point) by measuring the distance from m points (beacon points) with known spatial coordinates is called spatial distance intersection, edge measurement space resection or space edge measurement intersection in surveying and cartography. etc., the calculation method is as follows: [0003] Assume that at a certain moment, measured from the beacon point B 1 , B 2 , B 3 and B 4 …B m to the target point P j The distance is d j1 、d j2 、d j3 and d j4 … d jm ,Such as figure 1 shown, where B 1 , B 2 , B 3 and B 4 …B m The space coordinates of are known, respectively (x w1 ,y w1 ,z w1 ), (x w2 ,y w2 ,z w2 ), (x w3 ,y w3 ,z w3 ) and (x w4 ,y w4 ,z w4 )...(x wm ,y wm ,z wm ), the...
