I'm pretty excited to see this project released. This is from the researchers who made LSD-SLAM[0], a widely used monocular SLAM system, and DSO is showing some very impressive results in terms of accuracy, robustness and efficiency. For convenience, here are a few more resources related to this release:
* Video demo (with ORB-SLAM and LSD-SLAM comparisons): https://www.youtube.com/watch?v=C6-xwSOOdqQ https://www.youtube.com/watch?v=C6-xwSOOdqQ
* DSO research paper: https://arxiv.org/abs/1607.02565 https://arxiv.org/abs/1607.02565
* A small ROS wrapper for DSO was also released yesterday: https://github.com/JakobEngel/dso_ros https://github.com/JakobEngel/dso_ros
It'd be interesting to try and integrate DSO as a visual "sensor" for use with Google Cartographer [1]. This might allow people without a LIDAR or stereo/RGB-D/FOV cameras to perform fairly accurate and robust SLAM that's quite possibly efficient enough to run in realtime on a smartphone (although the rolling shutter cameras usually found in smartphones might complicate that a bit).

- ice109 10y agoforgive me if this is way off but does this, as a happy side-effect, solve the inertial navigation problem (i.e. commercial grade MEMS accelerometers in smart phones accumulate high amounts of error and therefore make intertial tracking impossible)?
- Jack000 10y agothats called a loop closure in SLAM systems. You would typically fuse the accelerometer data with odometry in an EKF as the best guess from dead reckoning, then correct that guess when it disagrees with lidar/camera data. Im not sure if DSO is a full SLAM system or if it only provides visual odometry, however.
- robotresearcher 10y agoThe demo video shows VO only, with no loop closure.
