摘要： Examples include systems and methods for decomposition of error components between angular, forward, and sideways errors in estimated positions of a computing device. One method includes determining an estimation of a current position of the computing device based on a previous position of the computing device, an estimated speed over an elapsed time, and a direction of travel of the computing device, determining a forward, sideways, and orientation change error component of the estimation of the current position of the computing device, determining a weight to apply to the forward, sideways, and orientation change error components based on average observed movement of the computing device, and using the weighted forward, sideways, and orientation change error components as constraints for determination of an updated estimation of the current position of the computing device.

摘要： One or more devices in a data analysis computing system may be configured to receive and analyze acceleration data corresponding to driving data, analyze the acceleration data, and determine driving patterns and associated drivers based on the data. Acceleration data may be collected by one or more mobile devices, such as smartphones, tablet computers, and/or on-board vehicle systems. Drivers associated with driving trips may be identified based on the acceleration data collected by the mobile devices. In some cases, driving patterns may be determined based on the acceleration data before and after stopping points during driving trips, and the driving patterns may be compared to a set of previously stored driving patterns associated with various different drivers.

摘要： A device and a method for determining a rough component of a latitude or longitude position of a moving craft. The position is reconstructed cyclically by combining the rough component with a corresponding fine component. The device determines the sign of a difference between the fine component for an acquisition cycle and the fine component for a preceding acquisition cycle. The device then computes the rough component corresponding to the given acquisition cycle of the fine component, as a function of the sign of the difference and of the sign and of the value of the speed of the craft. The device and the corresponding method make it possible to extrapolate an unrefreshed rough component as a function of the trend of the fine component and of the sign of the speed of the moving craft to reduce error associated with the computation of the latitude or longitude position.

摘要： A system and method for providing location information using a long baseline accelerometer/GNSS system. A first set of accelerometers is operatively associated with the first GNSS antenna while a second set of accelerometers is operatively associated with a second (or more) GNSS antenna. The multiple assemblies are separated by predefined distances and held rigid to each other. Accelerometer data is combined with the GNSS data to provide improved navigation and location information.

摘要： Disclosed in some examples are methods, systems, and machine readable mediums that provide location based services such as navigation in an indoor space by utilizing a network of specially configured locator nodes (LNs) and the identified line of sight (LOS) relationships between the LNs. The LOS relationships may be automatically learned by the LNs.

摘要： A method is described for determining a position of a two-wheeled vehicle. The single-track vehicle has a vehicle path yaw rate when driving along curves and a yaw rate according to the inclined orientation which differs from the vehicle path yaw rate. An inclined orientation of the single-track vehicle and a speed of the single-track vehicle are measured. The vehicle path yaw rate of the single-track vehicle is determined from the measured inclined orientation and the measured speed. A device for carrying out the method is also described.

摘要： A system of one or more computers can be configured to perform particular operations or actions by virtue of having software, firmware, hardware, or a combination of them installed on the system that in operation causes or cause the system to perform the actions. One general aspect includes a system, including a computer having a processor and a memory, the memory storing instructions executable by the processor such that the computer is programmed to receive an image of at least one lane marker from an image capture device mounted to a vehicle. The system also identifies a lane transition according to the image. The system can also control at least one of steering, braking, and acceleration of the vehicle according to a history of data concerning the lane transition locations.

摘要： A method for filtering in ranging of a UAV is provided, which is based on a characteristic that velocities of the UAV change continuously during a moving process. A current velocity of the UAV is obtained via seeking difference of distances measured by the sensor, then a variance of continuous velocities is calculated and it is determined whether a current distance is valid according to the variance. The general process of the method is as follows. First, initial distances measured by the sonar sensor are acquired, secondly, it is determined whether a new distance is valid according to the initial distances, if the new distance satisfies a curtain condition, the new distance is considered to be valid and the initial distances are updated; if the new distance does not satisfy the curtain condition, a distance is estimated and used as the current distance and the initial distances are maintained.
