One idea would be to leverage decades of research in monocular odometry and SLAM, and use an open-source package from any research group worldwide. We want to use this information to estimate the rotation matrix R and a translation vector t between the two camera frames. Stereo camera systems are inherently more stable than monocular ones because the stereo pair provides good triangulation of image features and resolves the scale ambiguity. You can use it to create highly accurate 3D point clouds or OctoMaps. Visual odometry (VO) methods do not have this prob-lem with initialization [6] but are inherently subject to both scale and spatial drift when operated on un-constrained plat-forms.

I am trying to implement monocular visual odometry in opencv python. Within the last ten years, a common sense has been established on how to implement high precision and robust systems. And when we say visual odometry by default we refer to monocular visual odometry just using one camera and this means that when we don't use any other censor we're still having unknown global scale.

ARM-VO: 8 FPS monocular visual odometry on Raspberry Pi 3 My master thesis was to design and implement a camera-based system for localization of a six-wheeled robot. I don't actually think that you need to implement all these stuff by yourself, maybe there's a function in OpenCV for the whole algorithm. Mahjourian, M. Rubio Romano. The following are 2 reasons why monocular visual odometry is not the best option: 1) Results from monocular sequences can only be recovered up to a 'scale'; without additional information, absolute measurements are not possible. If you are new to Odometry or Visual Odometry I suggest to read some good papers or tutorials about this subject, but if you are too anxious to know more about it, here are the basics. We want to use this information to estimate the rotation matrix R and a translation vector t between the two camera frames.
