Embodiment 1

[0043] A. First, use the 3D virtual modeling software of the prior art to establish a 3D virtual scene calibration template for the driving simulation system. The main view is as follows: Figure 4 As shown, the top view is as image 3 As shown, the side view is as Figure 5 shown.

[0044] B. If image 3As shown, set a center on the above-mentioned three-dimensional virtual scene calibration template as the binocular viewpoint 3,31, that is, the driver's binocular in the driving simulator 8, the distance between the binocular viewpoint 3,31 is a=0.065m, And set an arc surface with a radius of R as the center of the circle, that is, the reality W, and set six upright red and white benchmarks 1, 11, 12, 13, 14, 15 on the reality W from left to right ( i.e. the target), the height of the benchmark is H=3m, the distance between the benchmark 1,11, the benchmark 12,13, and the benchmark 14,15 is L=3m, and the distance between the benchmark 11,12, and the benchmark 13,14 is J=3...

Abstract

The invention discloses a calibration method of a three-dimensional virtual image of a driving analog system, which completes the calibration of a target object in a virtual scene by respectively solving out a distance PL between every two projected target objects, a height PK of projected target objects and a height PH from the bottom of each projected target object to the ground based on a calibration template of a three-dimensional virtual scene of the driving analog system established by three-dimensional virtual image modeling software in the prior art, and completes the calibration of a displayed target object in the virtual scene by solving out the amplification factor of the displayed target object in the virtual scene. The invention can carry out calibration on object spatial dimension and effective sighting distance in the three-dimensional virtual image of the driving analog system in a faster, more comprehensive, more accurate and more objective way and simultaneously solves the problems of only individual-specificity and generality deficiency in the static virtual image calibration technology of the traditional driving analog system.

Description

technical field [0001] The invention relates to an image calibration method, in particular to a calibration method for a three-dimensional virtual image of an automobile driving simulation system. Background technique [0002] Research-type car driving simulation system is a virtual simulation device that can simulate driver-car-road traffic behavior and enable the driver to obtain a driving feeling similar to that of a real car. Because in the driving simulation system, the driver obtains more than 90% of the information through the eyes, so the technology of three-dimensional virtual image is the most important part of the driving simulation technology, which must make the driver's vision close to the real feeling. [0003] At present, the three-dimensional virtual image in the driving simulation system is completed by computer generation, projector amplification, video display and other links. Therefore, the virtual image seen by the driver is quite different from the act...
