Abstract

The invention provides a simulation picture confidence evaluation method. The simulation picture confidence evaluation method comprises the steps of obtaining at least one real numerical value resultaccording to image features of a sample image in a sample set, wherein the image features can enable the probability that the real value results calculated by any two images in the to-be-detected image set are different to be greater than a preset threshold; calculating a confidence evaluation value component corresponding to the i real value result of the to-be-measured image according to a formula; and calculating an average value of the confidence evaluation value components of all the real value results to obtain a confidence evaluation result. The defect that in the prior art, evaluation is mainly based on the simulation process, and the confidence coefficient obtained by directly comparing a simulation image result with a real shot picture library is lacked is overcome. The method has high expandability, can evaluate general simulation pictures, and is not limited to simulation objects.

Description

technical field [0001] The invention relates to the field of visual simulation, in particular to a method for evaluating the confidence of a simulated picture. Background technique [0002] With the popularization of computers in civilian industries such as games and movies and military industries such as semi-physical simulation in recent decades, many 3D visual simulation software have emerged as the times require. Accompanied by the development of a large number of theoretical studies on 3D rendering of simulation software, such as the parameterization of the bidirectional reflectance distribution function of rough surfaces and the optimization of the three-dimensional structure's planar projection algorithm, the confidence of the simulation image (that is, the comparison with the real photo Similarity) studies have also emerged. At present, the research on the confidence of simulation images at home and abroad mainly focuses on the systematic VV&A monitoring and evaluat...
