Ground truth
Ground truth for indoor datasetsDecember 17, 2007
As already explained here, indoor datasets from Rawseeds include two kinds of ground truth: executive drawings and robot trajectory. To reconstruct the trajectory of the robot through the explored environment, we used two separate systems: a system based on industrial cameras, visual tags mounted on the robot, and ad hoc software a system using a […]
Ground truth for outdoor datasets
As already explained here, outdoor datasets from Rawseeds include two kinds of ground truth: executive drawings and robot trajectory. To reconstruct the trajectory of the robot through the explored environment, we used a high precision RTK (Real Time Kinematics) GPS system. Rawseeds’ RTK-GPS setup was composed of: a Trimble 5700 GPS receiver with Zephyr GPS […]
What is ground truth?
Together with each of the datasets, Rawseeds provides the associated ground truth. This is a set of information describing the real environments explored by the robot, and the trajectory followed by the robot within such environment. Ground truth is used as a reference, against which the results obtained by a Benchmark Solution can be evaluated. […]
