Control system for work machine, work machine, and management system for work machine
A control system includes: a detector detecting a position of a work machine running on a running path; a non-contact sensor detecting an object at a side of the running path; a generator generating map data of a work site based on detection data from the detector and the non-contact sensor; a first storage storing past map data generated in the generator based on the detection data from the detector and the non-contact sensor acquired in a predetermined period in a past; a second storage storing current map data generated in the generator based on the detection data from the detector and the non-contact sensor; a first calculator calculating integrated map data by integrating the past map data and the current map data; and a second calculator by matching the integrated map data and the detection data from the non-contact sensor, calculates the position of the work machine.
MANAGEMENT SYSTEM FOR WORK MACHINE, WORK MACHINE, AND MANAGEMENT DEVICE FOR WORK MACHINE
A management system 1 for a work machine includes: a plurality of dump trucks 2 each creating a map information piece DTI of a sectioned region DT around the own vehicle; and a management device 10 that manages map information pieces DTI of a plurality of sectioned regions DT created by the plurality of dump trucks 2 and transmits, to each of the dump trucks 2, a map information piece DTI of a sectioned region DT where each of the dump trucks 2 exists and a map information piece DTI of a sectioned region DT adjacent to the sectioned region DT where each of the dump trucks 2 exists on the basis of information related to a position of each of the dump trucks 2.
Registration calculation of three-dimensional scanner data performed between scans based on measurements by two-dimensional scanner
A method for measuring and registering three-dimensional (3D) coordinates by measuring 3D coordinates with a 3D scanner in a first registration position, measuring two-dimensional (2D) coordinates with a 2D scanner while moving from the first registration position to a second registration position, measuring 3D coordinates with the 3D scanner at the second registration position, and determining a correspondence among targets in the first and second registration positions while moving between the second registration position and a third registration position.
Navigation device and method
Embodiments of the present invention relate to a device including a module (490) which is operative in a low-power state of the device (200). The module (490) is arranged to determine whether a traffic situation on a route has more than a predetermined affect on the route, and to cause the navigation device (200) to output a notification in response thereto which alerts the user of the device to the traffic situation despite the device being in the low-power state.
APPARATUS AND ASSOCIATED METHOD FOR USE IN UPDATING MAP DATA
An apparatus comprising a processor and memory including computer program code, the memory and computer program code configured to, with the processor, enable the apparatus at least to: use a classification model to identify one or more anomalies between a monitored trajectory of a vehicle through a road network and predefined map data for the road network which are likely caused by errors in the predefined map data; and provide details of the one or more identified anomalies for use in obtaining additional data for the specific locations on the road network corresponding to the one or more identified anomalies in order to correct the errors in the predefined map data.
Generalising topographical map data
Aspects described herein improve upon systems and methods for generalizing topographical map data relating to the road network for use at different scale levels. Existing systems collapse the two carriageways of a dual carriageway to a single centerline representing the dual carriageway by tracking along one way sections of carriageway and generating pairs of carriageways for collapse, but fall short of being able to compute complicated intersections. Further, existing methods place heavy demands on processing power and are not suitable for change only refreshes. Aspects described herein use graph theory to create a tracked network of stroke type objects representing the length of single carriageway sections of dual carriageways, and then successfully pairs them such that they can be collapsed to a center line and connected to the road network. The process reduces computation time, thereby speeding the rendering process for map imagery.
Identifying a change in a home environment
A system and computer implemented method for detecting a change in a home environment for a visually impaired user is disclosed. The method may include monitoring the home environment using a set of sensors configured to collect environment data for a set of areas of the home environment. The method may also include detecting an environmental change in an area of the home environment. The method may also include providing, in response to a triggering event, a notification of the environmental change.
METHOD AND APPARATUS FOR UPDATING ROAD MAP GEOMETRY BASED ON RECEIVED PROBE DATA
A method is provided for generating and revising map geometry based on a received image and probe data. A method may include: receiving probe data from a first period of time, where the probe data from a first period of time is from a plurality of probes within a predefined geographic region; generating a first image of the predefined geographic region based on the probe data from the first period of time; receiving probe data from a second period of time different from the first period of time, where the probe data from the second period of time is from a plurality of probes within the predefined geographic region; generating a second image based on the probe data from the second period of time; comparing the first image to the second image; and generating a revised route geometry based on changes detected between the first image and the second image.

MAP GENERATING DEVICE, MAP GENERATING METHOD, AND PROGRAM RECORDING MEDIUM
An identification unit obtains a plurality of photographic images including two or more markers. The makers are placed on a different object, respectively. The identification unit identifies, from the plurality of photographic images thus obtained, three-dimensional positions of the two or more markers. A generating unit transforms coordinate system of the plurality of photographic images into a common coordinate system. Relative positions of the two or more markers based on a specific location are indicated in the common coordinate system. The generating unit generates map data which associates the positions of the two or more markers.
