Robust 3-D-3-D pose estimation 总被引:1,自引:0,他引:1
Xinhua Zhuang Yan Huang 《IEEE transactions on pattern analysis and machine intelligence》1994,16(8):818-824
The correspondence focuses on the robust 3-D-3-D pose estimation, especially, multiple pose estimation. The robust 3-D-3-D multiple pose estimation problem is formulated as a series of general regressions which involve a successively size-decreasing data set, with each regression relating to one particular pose of interest. Since the first few regressions may carry a severely contaminated Gaussian error noise model, the MF-estimator (Zhuang et al., 1992) is used to solve each regression for each pose of interest. Extensive computer experiments with both real imagery and simulated data are conducted and results are promising. Three distinctive features of the MF-estimator are theoretically discussed and experimentally demonstrated: It is highly robust in the sense that it is not much affected by a possible large portion of outliers or incorrect matches as long as the minimum number of inliers necessary to give a unique solution are provided; It is made virtually independent of initial guesses; It is computationally reasonable and admits an efficient parallel implementation 相似文献

一部《阿凡达》,让3D概念在2010年火爆起来,3D电视等设备纷至沓来。不过让用户觉得不太爽的一点是3D的内容实在是不多,经常让花大价钱买来的3D电视无用武之地。 相似文献

3-D pose from 3 points using weak-perspective 总被引:3,自引:0,他引:3
This correspondence discusses computing the pose of a model from three matching point pairs under weak-perspective projection. A new approach to the problem that is motivated geometrically is described. Like previous methods, the method here involves solving a biquadratic equation, but here the biquadratic's solutions, comprised of an actual and a false solution, are interpreted graphically. The final equations take a new form, which leads to a simple expression for the image position of any unmatched model point 相似文献

在暴雪公司副总裁Rob Pardo最近的一次谈话中,我们似乎看到了一些关于《暗黑破坏神3》上市时间的暗示。Rob Pardo表示:“我们总是过早的宣布我们的那些游戏,我认为现在最安全的说法是,《暗黑破坏神3》正式发售还需要一些时间。” 相似文献
