More Information
Summary:The invention discloses a topographic data processing method and device based on parallel search. The method comprises the following steps: initializing target parameters of a target area; searching a target density difference and a target depth in parallel through a simulated annealing method; based on the target density difference and the target depth, taking the filtering matrix parameter as a variable, and performing iterative search through a parallel search strategy to obtain a target filtering matrix parameter; and according to the target density difference, the target depth, the target filtering matrix parameter and the gravity anomaly matrix, performing processing through a Parker-Oldenburg inversion method to obtain the mourhue surface depth of the target area. According to the embodiment of the invention, a simulated annealing method and a filtering matrix parameter self-adaptive updating method are combined together, automatic parameter adjustment of all parameters is ensured, parallelization proc
