Benefits of technology

This technology solves problems with complicated scenes that may appear on an optical sensor used by missiles or other vehicles during flight simulations. It works well even if there are different types of objects like rocks near them. By applying this technique it helps improve the accuracy and reliability of guided munitions systems (GMDs).

Problems solved by technology

This patented describes how computer simulations can become very complicated due to the use of multiple layers that combine data from various sources like images onto screens with varying degrees of detail. These issues include image quality distortion caused by overlapping areas where no important details may occur (fuzzy edges) and ghost effects such as blinking around certain points within an area covered by other elements.

Embodiment Construction

[0015] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0016] A method to solve complex target and background model flickering of target simulator. The method comprises the steps of:

[0017] 1) Import the model created by the third-party software into the creator software, and optimize and adjust the openflight hierarchical structure of the model in the creator software according to the simulation requirements;

[0018] 2) Decompose the concave polygonal faces in the above model into triangular faces in the creator software, and delete redundant faces;

[0019] 3) Redefine and set the patch properties of the model processed in step 2);

[0020] 4) Use the visual simulation software to drive the model processed in step 3). In the visual simulation software, observe whether the model has overlapping surfaces or irregular seams when moving. If the model has overlapping surfaces or irregular seams when moving, then Creator

Abstract

The invention discloses a method for solving the problem of the flickering of a complex target and a background model of a target simulator, and belongs to the technical field of semi-physical simulation system tests. The method adopting the technical scheme mainly comprises the following steps of introducing creator software into a refined model created by third party software; performing structure optimization and attribute optimization; processing polygons and facets, and resetting the processed polygons and the processed facets; deleting overlapped surfaces; completing seams; finally, performing later-period optimization on a complete target scene by an LOD manner according to the field angle parameter of the target simulator, the field angle parameter of a guiding head, and design requirements for the simulation of trajectory to guarantee that during loading and running, a generated image is natural in transition and has no flickering. The method disclosed by the invention provides a series of procedures which are suitable to be applied to the target simulator to solve the problem of flickering. The problem of the flickering of the target scene image output by the target simulator to the guiding head can be effectively solved, the stability of the scenery image effect is guaranteed when the guiding head captures and controls a target, and the confidence coefficient of simulation results is increased.
