Aiming at the scheduling problem of underground mining equipment in shot mining, this paper proposes an improved cultural gene algorithm (MA). The global search applies the genetic algorithm, and some adjustments are made in its crossover and mutation operations; the local search uses the simulated annealing algorithm. The global search applies the genetic algorithm, and some adjustments are made in its crossover and mutation operations; the local search uses the simulated annealing algorithm, considering that the algorithm will have a certain probability to jump out of the optimal solution range, so on the basis of the original algorithm, the Gaussian function is replaced by the Cauchy function to avoid this problem. The algorithm is applied to the scenario of 5S15J for simulation experiments. After that, compared with the results of the genetic algorithm, it shows that the improved MA algorithm is obviously better in total time and total interval time, and can obtain high-quality solutions and an ideal cooperative scheduling strategy.
In the aerial photogrammetry, the position and attitude information of the aerial camera at the time of exposure can be obtained through the positioning and orientation system carried on board, which is introduced into the collinear equation to solve the geodetic coordinates of the target points, and the direct geographic positioning can be completed and positioning the lever arm of directional system will bring the output error, resulting in collinear equation of deviating from the collinear condition, thus affecting the precision of the target for the quantitative analysis of the lever arm effects on the accuracy of positioning and orientation system, this paper analyzes the inertial measurement unit under different installation method of the lever arm type, use the data analysis of two kinds of semi-physical simulation installation effect the precision of the system, in when the pendulum is swept at 60 degrees, the attitude error is about 0.01. According to the results, the error compensation model of the lever arm is established, which provides a theoretical basis for compensating the influence of the lever arm error.
