Fast Monocular Visual Compass for a Computationally Limited Robot
نویسندگان
چکیده
This paper introduces an extremely computationally inexpensive method for estimating monocular, feature-based, heading-only visual odometry a visual compass. The method is shown to reduce the odometric uncertainty of an uncalibrated humanoid robot by 73%, while remaining robust to the presence of independently moving objects. High efficiency is achieved by exploiting the planar motion assumption in both the feature extraction process and in the pose estimation problem. On the relatively low powered Intel Atom processor this visual compass takes only 6.5ms per camera frame and was used effectively to assist localisation in the UNSW Standard Platform League entry in RoboCup 2012.

High-Fidelity Planetary Route Determination Using Computationally Efficient Monocular Fisheye Odometry and Sun Compass
Today’s planetary robotic exploration is carried out by large, lumbering rovers. Due to the expense of such rovers, the resulting missions are risk averse. Small, high-cadence, minimalist rovers are poised to break new ground by expanding space exploration capabilities. Whether by decreasing overall mission costs or enabling symbiotic exploration among multiple low-cost rovers, these minimalist...
متن کاملCombined visual odometry and visual compass for off-road mobile robots localization
In this paper, we present the work related to the application of a visual odometry approach to estimate the location of mobile robots operating in off-road conditions. The visual odometry approach is based on template matching, which deals with estimating the robot displacement through a matching process between two consecutive images. Standard visual odometry has been improved using visual com...

In this article, we present our work to provide a navigation and localization system on a constrained humanoid platform, the NAO robot, without modifying the robot sensors. First we try to implement a simple and light version of classical monocular Simultaneous Localization and Mapping (SLAM) algorithms, while adapting to the CPU and camera quality, which turns out to be insufficient on the pla...

Background : To determine the effect of binocular summation on the time domain transient VEP wave's components. Methods : The monocular and binocular transient visual evoked potentials of 21 normally vision volunteers 18 to 24 years (mean ± SD, 20.7 ± 1.9) during a reversing checkerboard stimulus with spatiotemporal frequency of 2.18-4 cpd-Hz were recorded. The amplitude and latency of N75,...
