People know Simcenter Prescan for its high-end physics-based sensor simulations. The simulation industry is using the term physics-based more frequently. However, you can misuse the term or interpret in different ways. For Simcenter Prescan, when we say that we have a physics-based sensor model...
今天分享一篇CVPR 2020上Uber发布的一篇论文LiDARsim: Realistic LiDAR Simulation by Leveraging the Real World[1],主要介绍通过真实世界进行三维重建,然后生成真实的激光雷达点云,并且在KITTI数据集上进行了对比。 三种模式仿真的优缺点 论文指出目前主要有3种不同形式的仿真。 真实场景下的路测和结构化测试 基于真实...
LIDAR Simulation 10hz 1000fps by Michael Gschwandtner 3D Loading 3D model Model is too heavy for your device and can not be rendered properly Model Inspector 00:00.00 x0.1 x0.5 x1 x2
You can use the “simulation 3D Lidar” block to get an interface for the lidar sensor. The block returns a point cloud data which is an array of positive real-valued [x,y,z] points. In addition, you can output the location and orientation of the sensor in the world coordinate system...
本文应用轨迹生成来创造动态效果,同时确保交通参与者(actors)之间以及交通参与者(actors)与场景之间的真实互动。最后,本文在每个时间步骤组合 3D 世界,并执行随机光线投射模拟(stochastic raycasting simulation)以产生最终的 4D 激光雷达序列。如图 1 所示,本文生成的结果多样化,与布局条件对齐,既逼真又时间上连贯。
德国海德堡大学(Heidelberg University)Bernhard Höfle教授团队的工程师Sebastian Bechtold(主要作者) 开发的HELIOS则具有如下特点(a flexible multi-purpose simulation framework): 支持真实三维几何,输入可以为obj模型文件、GeoTIFF地形高程文件(自动被转换为三角网)、ASCII格式的‘xyz’点云文件(自动被转换为体元) ...
