VINS-RGBD-FAST is a SLAM system based on VINS-RGBD. We do some refinements to accelerate the system's performance in resource-constrained embedded paltform, like HUAWEI Atlas200 DK, NVIDIA Jetson AGX Xavier.

• grid-based feature detection
• extract FAST feature instead of Harris feature
• added stationary initialization
• added IMU-aided feature tracking
• added extracted-feature area's quality judgement
• solved feature clusttering problem result frome FAST feature
• use "sensor_msg::CompressedImage" as image topic type

Based one open source SLAM framework VINS-Mono.

The approach contains

• Depth-integrated visual-inertial initialization process.
• Visual-inertial odometry by utilizing depth information while avoiding the limitation is working for 3D pose estimation.
• Noise elimination map which is suitable for path planning and navigation.

However, the proposed approach can also be applied to other application like handheld and wheeled robot.

1.1. Ubuntu 16.04 or 18.04.

1.2. ROS version Kinetic or Melodic fully installation

1.3. Ceres Solver Follow Ceres Installation

1.4. Sophus

Recording by RealSense D435i. Contain 9 bags in three different applicaions:

• Handheld
• Wheeled robot (Jackal)
• Tracked robot

Note the rosbags are in compressed format. Use "rosbag decompress" to decompress.

Topics:

• depth topic: /camera/aligned_depth_to_color/image_raw
• color topic: /camera/color/image_raw
• imu topic: /camera/imu

我们使用的是压缩图像节点：

• depth topic: /camera/aligned_depth_to_color/image_raw
• color topic: /camera/color/image_raw/compressed
• imu topic: /camera/imu

如何录制一个数据包

1. 运行d435i
2. rosbag record /camera/imu /camera/color/image_raw /camera/aligned_depth_to_color/image_raw /camera/color/camera_info /camera/color/image_raw/compressed
