Intel's SLAM library for ZR300 does that I believe. $149. Furthermore, we propose a method to dynamically adapt the number of particles which significantly reduces the computational complexity. The only thing missing in these two pipelines is high-quality inertial (IMU) integration, which If I have a good imu I could trust it more in both mapping and localization, while if I have a bad imu I need to rely more heavily on the scan match. Camera and IMU are considered rigidly attached and the transformation T CB = [R CBj Cp B] between their reference systems known from calibration [18].

The stereovision based approach is a classic SLAM implementation, whereas the monocular approach introduces a new way to initialize landmarks. However, the accuracy of the RGB-D SLAM relies heavily on correspondence feature points, and the position would be lost in case of scenes with sparse textures. These sensors may use visual data (such as camera imagery), or non-visible data sources (such as Sonar, Radar, or Lidar) and basic positional data, using an inertial measurement unit (IMU for short). 2016 · 三维计算视觉研究内容包括: 1)三维匹配:两帧或者多帧点云数据之间的匹配,因为激光扫描光束受物体遮挡的原因 Occupancy grid Node¶ The occupancy_grid_node listens to the submaps published by SLAM, builds an ROS occupancy_grid out of them and publishes it.
