The development of the SnowEater robot navigation system using a simple camera and marker is presented in this paper. The SnowEater is a crawler robot developed to accomplish the snow removal task within an autonomous operation with low power consumption. Current snow blower and snow plow machines consume a lot of power and are made to complete the operation under the constant surveillance of the...
This study presents a laser/vision-based tracking of people in 3D space. A sensor node consisting of a two-layered laser-range scanner (LRS) and fisheye camera is placed in an environment. LRS detects the heads and knees of people, and the camera captures the color images of people detected by the LRS. From the position data of people scanned by LRS, peoples' motion in the horizontal plane is tracked,...
This paper presents laser-based pedestrian tracking system in outdoor environments using multiple mobile robots. Each robot detects pedestrians using its own laser scan image by an occupancy-grid-based method and tracks the detected pedestrians via Kalman filtering. When the robots are in close proximity to each other, they exchange pedestrian tracking information through intercommunication, and tracking...
This paper reports construction of a new device to capture 3D point cloud on human body. The device consists of a horizontal LIDAR, a vertical LIDAR and pan rotational mechanism. The device contain three main features. 1) The device can capture point cloud in large area using combination of the vertical LIDAR and the rotational mechanism. 2) The device can measure dense point cloud using mirror reflection...
