Abstract: A tracking device including an image sensor, a light source and a processor is provided. The image sensor senses reflected light or scattered light formed by the light source illuminating a work surface. The processor calculates a trace of the tracking device according to one of the reflected light and the scattered light that generates more apparent image features so as to increase the adaptable work surfaces.

Abstract: A method for position and/or deviation correction of a moving object in a simultaneous localization and mapping (SLAM) environment. The method comprises receiving at the moving object point cloud data for an area associated with the moving object from a sensor located at a fixed location. A processor of the moving object performs the steps of: transforming the received point cloud data to a coordinate system of the moving object; matching the transformed point cloud data with point cloud data generated by a sensor at the moving object for the area associated with the moving object; and using the matched point cloud data to determine a corrected position and/or deviation of the moving object within a selected coordinate system.

Abstract: A buried object scanning device includes a capacitance sensor, a search image conversion processing unit, a memory unit, a display unit, an operation input unit, and a display control unit. The capacitance sensor detects a buried object. The search image conversion processing unit converts the detection result of the capacitance sensor into a search image. The memory unit stores search images and a grid layer including grid lines corresponding to a specific scale. The display unit displays the search images and the grid layer. The display control unit controls the display unit to display the search image superimposed with the grid layer and to display the search image in a state of being movable relative to the grid layer, in response to input to the operation input unit.

Abstract: A system has a collection of lidar sensors to generate lidar point cloud data for a defined geolocation. A computer is connected to the collection of lidar sensors via a network. The computer includes a processor and a memory storing instructions executed by the processor to process the lidar point cloud data to produce an object list for each moving object identified in the lidar point cloud data. The object list includes object classification information, object motion information, object position data, and object size data. Object motion analyses are performed on each object list to generate object motion analytics for the defined geolocation.
