摘要： A method for displaying images using an AR device. GNSS position data is received based on wireless signals received from a GNSS satellite. Based on the GNSS position data, a first GNSS point within a geospatial frame is determined within a first time range and a second GNSS point within the geospatial frame is determined within a second time range. Based on camera POS data, a first AR point within an AR frame is determined within the first time range and a second AR point within the AR frame is determined within the second time range. One of the frames is shifted such that the second GNSS point is aligned with the second AR point. An angle formed by the GNSS points and the AR points is calculated. One of the frames is rotated by the angle.

摘要： Methods and systems detect physical locations of vessels. A first satellite includes a first image sensor. A second satellite includes a second image sensor. The processor receives a first image of a target area from the first image sensor, and a second image of the target area from the second image sensor. Both images are taken within a predetermined time frame. The processor performs image recognition to identify a vessel that appears in both the first image and the second image. The processor receives the first satellite's location and orientation when the first image is taken and the second satellite's location and orientation when the second image is taken. Each satellite's location and orientation are determined by the satellite's geographic determination module. The processor determines the vessel's location by performing triangulation based on the first satellite's location and orientation and the second satellite's location and orientation. The processor outputs data representative of the vessel's determined location. The vessel's speed and bearing are also determined by the processor.

摘要： A vision system of a vehicle includes a camera disposed at a vehicle and having a field of view forward of the vehicle and operable to capture image data. A vehicle-based GPS system is operable to determine a geographical location of the vehicle. A control includes an image processor operable to process image data captured by the camera. Responsive at least in part to processing of captured image data by the image processor to determine lane markings and responsive at least in part to the GPS system and responsive at least in part to map data mapping the road along which the vehicle is traveling, the control is operable to determine an enhanced estimation of the path of travel of the vehicle. The enhanced estimation may be based on reliability levels or weighting factors of the determined lane markings and the map data.

摘要： A method for determining depth of a conduit below a ground surface includes moving an inline tool along and within the conduit and collecting pipeline elevation data of the conduit. The method also includes placing a plurality of aircraft targets on the ground surface above the conduit and collecting, by an aircraft, surface data of the ground surface. The method includes receiving, at a controller, survey data of the ground surface. The method includes determining, based on the surface data and the survey data, an ellipsoidal height of the ground surface and determining a depth of cover of the conduit based on the ellipsoidal height and the pipeline elevation data.

摘要： A vehicle warning system includes a wireless communicator and an electronic controller. The wireless communicator is configured to receive data related to an area surrounding a vehicle and a trailer being towed by the vehicle, the data representing points of interest on the vehicle and on the trailer. The electronic controller is configured to determine a travel path of a host vehicle different from the vehicle, and generate a warning signal upon determining that the travel path indicates entry of the host vehicle into the area.

摘要： An electronic communications terminal records in a memory a sampled audio segment of sound sensed by a micro-phone. A time stamp associated with timing of the recording of the sampled audio segment is determined and stored in the memory associated with the sampled audio segment. The sampled audio segment and the time stamp are transmitted through a network interface toward a location service client of a network node that determines location of the electronic communications terminal based on correlating the sampled audio segment and other sampled audio segments of the sound received from other electronic communications terminals. A related network node and corresponding methods by terminals and network nodes are disclosed.

摘要： A system and method for improving the accuracy of a user device when generating map/navigation information for display to a user, comprising: obtaining compass heading from a magnetometer of the user device located within a vehicle; adjusting the compass heading based on a mount angle of the user device within the vehicle; obtaining location data from a location sensor of the user device; determining if a course of the vehicle can be reliably determined from the location data; if the course of the vehicle cannot be reliably determined from the location data, determining the orientation of the vehicle using the compass heading but not the course; if the course of the vehicle can be reliably determined from the location data, calculating a course of the vehicle based on the location data and determining the orientation of the vehicle using the course; generating, by a processor, first map/navigation information using the orientation of the vehicle; and displaying, by a processor, the first map/navigation information to the user.

摘要： Concepts for generating navigation instructions for a driver of a vehicle are presented. One example, includes obtaining a current location of the vehicle, a route for the vehicle from the current location to a target destination, and a captured image of the surrounding environment of the vehicle, the image having a field of view comprising at least part of a field of view of the driver. An object is identified in the captured image. Navigation instructions for the driver are generated based on the current location of the vehicle, the route for the vehicle and the object identified in the captured image.

摘要： Systems and method are provided for participative map anomaly detection and correction. In one embodiment, a processor-implemented method for map anomaly detection is provided. The method includes receiving, by a processor in a vehicle, pre-planned trajectory data from a navigation module in the vehicle, retrieving, by the processor, sensor data from one or more vehicle sensing systems, analyzing, by the processor, the sensor data and the pre-planned trajectory data, identifying, by the processor, an anomaly from the analysis, and transmitting information regarding the anomaly to a central repository external to the vehicle wherein the central repository is configured to analyze the information regarding the anomaly to determine if a navigation map attribute is incorrect.
