摘　　要：受到三维场景重建图像特征时间变量差异与特征精度约束要求较高的限制,传统虚拟实验室场景三维重建模型的计算效果与预期效果差距较大,主要体现在三维场景数据误差与计算效率两项指标偏大。为更好地解决这个问题,引入AKAZE算法对其进行三维构建参量的优化,具体实现分为四个步骤,分别为虚拟实验室场景三维重建模型的AKAZE非线性尺度空间特征确定与提取、虚拟实验室加速的非线性扩散三维空间构建、虚拟实验室三维边缘信息融合及虚拟实验室三维场景重建模型输出。通过对模型效果的仿真测试表明,经过AKAZE算法优化后的模型三维构建准确度更高、响应更快、稳定性更好、方法易于实现,具有较高的推广价值。Restricted by the difference of the characteristic time variable of 3D scene reconstruction images and the high requirement of the feature accuracy constraint,the gap between the calculation effect and the expected effect of the traditional virtual laboratory scene reconstruction model is large,which is mainly reflected in the large error of data and calculation efficiency of 3D scene.In order to better solve this problem,the introduction of Accelerated-KAZE(AKAZE)algorithm for 3D construction parameter optimization,in which concrete implementation is divided into four steps,that is,AKAZE nonlinear scale space feature determination and extraction of the virtual laboratory scene 3D reconstruction model,the nonlinear diffusion 3D space construction of virtual laboratory acceleration,3D edge information fusion of virtual laboratory and 3D scene reconstruction model output of virtual laboratory.The simulation test of the proposed model effect shows that the model optimized by AKAZE algorithm has higher 3D construction accuracy,faster processing response,better stability,and is easy to implement,which is of high value for promotion.
