摘要： A driver assistance system for an ego vehicle, and a method for a driver assistance system is provided. The system is configured to refine a coarse geolocation method based on the detection of the static features located in the vicinity of the ego vehicle. The system performs at least one measurement of the visual appearance of each of at least one static feature located in the vicinity of the ego vehicle. Using the at least one measurement, a position of the ego vehicle relative to the static feature is calculated. The real world position of the static feature is identified. The position of the ego vehicle relative to the static feature is calculated, which is, in turn, used to calculate a static feature measurement of the vehicle location. The coarse geolocation measurement and the static feature measurement are combined to form a fine geolocation position. By combining the measurements, a more accurate location of the ego vehicle can be determined.

摘要： A method and system for using GPS signals and a magnetic field to track an underground magnetic field source. A tracker having an antenna for detecting the magnetic field and a GPS receiver is coupled to a processor. The magnetic field is used by the antenna to direct the tracker to a field null point. Once multiple measurements of the field are taken, the changes in signal strength as the absolute position of the tracker is changed, are used to determine whether the closest field null point is in front of or behind the underground beacon. The position and depth of the beacon can then be estimated.

摘要： System includes one or more processors configured to receive location data from a device communication unit and from at least a first communication unit and a second communication unit that are positioned relative to a vehicle. The location data includes a device spatial location of the device communication unit, a first spatial location of the first communication unit, and a second spatial location of the second communication unit. The one or more processors are further configured to determine a vehicle spatial location of a designated point of the vehicle. The one or more processors are further configured to generate a virtual model. The virtual model, when used by a positioning system to locate the vehicle, indicates the vehicle spatial location relative to an estimated location of the vehicle.

摘要： This application provides a positioning method performed at a computer device. The method includes: obtaining an image photographed by an image capturing apparatus disposed at a roadside and a photographing orientation of the image; determining pixel coordinates in the image for a target object in the image; determining a relationship between the pixel coordinates corresponding to the photographing orientation and location coordinates in a physical world; and determining location coordinates of the target object in the physical world according to the relationship and the pixel coordinates. According to this application, location information of an object can be accurately determined according to a correspondence between pixel coordinates in an image and location coordinates in a physical world, and a transform relationship between pixel coordinates in different photographing orientations, and avoiding the problem that the target object cannot be positioned due to a blind area in a view field.

摘要： A vehicle system is provided for correcting in real-time a camera-based estimated position of a road object. The system includes a camera for generating an image input signal including image sensor data associated with the road object. The system further includes one or more input devices for generating a vehicle input signal including vehicle sensor data associated with a position, a speed, and a heading of the vehicle. The system further includes a computer, which includes one or more processors and a non-transitory computer readable medium (CRM) storing instructions. The processor is programmed to match the image sensor data and the vehicle sensor data to one another based on a common time of collection. The processor is further programmed to determine an error model and a deviation of a current camera-based position from a predicted position. The processor is further programmed to update the error model based on the deviation.
