标定系列二 | 实践之Camera-Odometry标定 标定系列三 | 实践之Camera-Lidar标定 本文作者是旷视研究院研究员柴政,他主要向大家介绍了Camera-Odometry标定,包括一些基础知识回顾、码盘内参和相机码盘外参标定、开源代码使用方法和注意点介绍等。公式较多但都较容易推导,希望能够给大家一些启发。 目录 1. 基础知识回顾 1.1...
We also derive the covariance matrix of the wheel odometry edges which is important when using graph-based optimization. Simulation experiments are used to validate the extrinsic calibration. For real-world experiments, we use our method to fuse the semi-direct visual odometry (SVO) with wheel ...
3.2.1 系统可观性的判断 熟悉VIO(visual inertial odometry) 系统也会熟知可观性问题。实际上,系统的可观性在线代控制理论中有专门论述,涉及到可观性矩阵等知识点,但是那套从线性系统出发的理论可能容易让大家迷惑。这里会从大家熟知的非线性优化求解的角度来简单描述可观性问题。 关于状态量参数是否可观的一个简单解释...

Enable IMU Fusion : If this option is enabled, the ZED SDK will use the internal IMU data of the ZED Camera, along with visual odometry, to find its orientation and position in the real world. This results in more accurate tracking, so you will want to keep this on most of the time...

我们在两个数据集上进行了实验,第一个数据集来自KITTI Odometry Benchmark,其中包括Velodyne HDL-64E LiDAR和一个高分辨率的彩色相机,扫描频率为10HZ。用于实验的数据是同步的和矫正的,可以从提供的校准文件中获取外部参数的地面真值。第二个数据集来自我们的自动驾驶汽车,配备有RoboSense RS-LiDAR-32 LiDAR传感器和一...
