Abstract. The Photogrammetry Department of MIIGAIK is developing the "Automated Information Generation System" (AIGS), which is designed to carry out automatic aerial survey of the object using a drone and obtain documents about the terrain (orthophotos, DMR, etc.). The system is based on a robotic mobile platform with a navigation system installed on it, a manipulator and a lifting portal. The manipulator has three degrees of freedom and is designed to manipulate the necessary when replacing automatically the battery in the UAV. The lifting portal is designed to load and fix UAVs on the platform. The robotic station is able to work both individually and as part of a network of stations. Complexes are evenly distributed on the territory where aerial photography or monitoring will be carried out. The operator is in the office, forms the job and sends it over the Internet channel, at the station. The job is run automatically on schedule.
Abstract. The paper considers the possibility of using low-cost stereo cameras for autonomous robot navigation. An low-cost stereo camera with a focal length of 5 mm and a photo base of 6 cm was chosen for the research. Experimental studies have shown that the accuracy of determining the coordinates of object points from a pair of images obtained by such a stereo camera is sufficient for organizing autonomous navigation of the robot. In order to improve the reliability and accuracy of determining the trajectory of the robot, this paper proposes to use two stereo cameras. One is directed forward by the robot's movement, and the other is directed at the nadir. Thus, the trajectory is determined twice, independently of each other. Moreover, each case has its own algorithm for finding the homologue points. In the first case, a sparse point cloud is constructed for each stereo pair based on the selection of interesting points and their identification based on the comparison of descriptors. In addition, blunder detection of points identification are realized based on the analysis of the values of the relative orientation equations using the fundamental matrix. In the second case, when the stereo camera is pointed at the nadir, the usual method of correlation is used in the nodes of the grid specified at one image. Experimental studies have shown sufficient efficiency of autonomous navigation of mobile robot based on the use of two stereo cameras.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
