Embodiment Construction
[0019] Compared with the existing method for measuring the gun barrel adjustment angle, a system method for the detection of artillery attitude parameters with a total station has been greatly improved and innovated in the measurement principle, calculation model and measurement accuracy. Specifically, :
[0020] (1) Set up a total station for the first measurement of the selected artillery barrel, assuming that its coordinates are (0,0,0), paste crosshairs on both ends of the muzzle, and adjust the collimation axis of the total station to a horizontal position Observe the crosshairs at both ends of the gun barrel, gradually adjust the gun barrel to a horizontal state, and set this direction as the zero direction of the total station azimuth. If the fort is high and it is difficult to adjust it to an absolute horizontal state, the gun Adjust the gun barrel to be approximately horizontal, and record the height angle β of the trajectory axis of the gun barrel at this time 0 ; ...

The invention discloses a total-station instrument real-time detection method for artillery attitude parameters. The method comprises the steps: the corresponding position of the body of a to-be-measured gun barrel is marked and calibrated; measuring targets with fixed positions are arranged above and on the side face of the gun barrel respectively, the artillery gun barrel is monitored and calibrated through a high-precision total-station instrument, and the gun barrel trajectory axis fixed difference relation, namely the horizontal angle difference [delta]alpha, the altitude angle difference[delta]beta and the heeling angle difference [delta]gamma, is determined by establishing an algorithm; absolute positioning and orientation of the measurement system are realized by using Beidou RTK,and a coordinate system is determined; and finally, according to the gun barrel calibration difference value, the total-station instrument is used for completing accurate measurement of any posture of the artillery gun barrel, and real-time detection of the artillery gun barrel posture parameters is achieved. According to the system method, the new system measurement method is established mainlyfor the measurement problem of the gun barrel trajectory axis attitude after the artillery position is adjusted, and the purpose of accurate real-time detection of the gun barrel attitude is achieved.
Description
[0001] 1. Technical field [0002] The invention relates to a method for measuring the attitude position of a cannon barrel at any time, in particular to a system method for realizing real-time detection of cannon barrel attitude parameters by using a high-precision total station in conjunction with satellite navigation and positioning. [0003] 2. Technical background [0004] The inspection of the aiming device in the traditional gun adjustment accuracy inspection of the fort mainly uses the "distant aiming point method" and the "plumb line method", etc., but currently uses the method of aiming and measuring with two electronic theodolites. These methods are more or less There are some deficiencies and areas worthy of improvement, such as low measurement accuracy and heavy detection workload, etc., and the actual adjustment angle of the fort cannot be accurately measured. "Inconsistencies require a new, efficient, and high-precision measurement method. [0005] 3. The conten...
