摘要： In a method and system for position capture of a vehicle along a driving route, situated on a concrete floor having a reinforcement: the vehicle carries out a reference drive along the driving route, the vehicle records measuring points along the driving route, and each measuring point allocates a signal from the reinforcement to a position on the driving route; a reference profile of the driving route is determined based on the measuring points ascertained during the reference drive; the vehicle drives along the driving route and records further measuring points; a profile segment is determined from the further measuring points; the profile segment is uniquely allocated to a segment of the reference profile, e.g., using a correlation method; a position on the driving route is uniquely allocated to the vehicle with the aid of the profile segment allocated to the reference profile.

摘要： A radar system includes a split-block assembly unit comprising a first portion and second portion, where the first portion and the second portion form a seam. The radar system further includes a plurality of ports located on a bottom side of the second portion opposite the seam. Additionally, the radar system includes a plurality of radiating elements located on a top side of the first portion opposite the seam. The plurality of radiating elements is arranged in a plurality of arrays. The plurality of arrays includes a set of multiple-input multiple-output (MIMO) transmission arrays, a set of synthetic aperture radar (SAR) transmission arrays, and at least one reception array. Further, the radar system includes a set of waveguides configured to couple each array to a port.

摘要： A dam slope deformation monitoring system and method are provided. The monitoring system monitors an entire dam in a reservoir area by using an unmanned aerial vehicle (UAV) photogrammetry system, and determines an encrypted monitoring area (steep slope) with the relatively large deformation and a relatively large digital elevation difference; determines, in the intensive monitoring area, a first level key monitoring area with the larger deformation by using a ground-based radar interferometry measurement system; determines, in the first level key monitoring area, a second level key monitoring area with the larger deformation by using a ground-based three-dimensional lidar measurement system; determines, in the second level key monitoring area, a key monitoring particle with a high deformation speed by using a global navigation satellite system (GNSS). The core chip stack is used to monitor and warn the collapse process in the area where the key monitoring particles are located.

摘要： Disclosed is a control assistance device that includes a radar system that detects surrounding objects, and generates radar tracking information tracking a position of the surrounding object relative to a vehicle, and a camera system, that includes cameras, and generates image information, and camera tracking information tracking the position of the surrounding object. The control assistance device also includes processors that determine whether the radar tracking information is generated in real time when the surrounding object approaches within a preset distance from the vehicle based on generated tracking information that includes the radar tracking information or the camera tracking information, determine whether the camera tracking information is generated in real time, when the radar tracking information is determined as generated in real time, and control a braking system of the vehicle based on the generated tracking information, when the camera tracking information is determined as generated in real time.

摘要： Camera data and radar echoes are received from the surroundings. At least one radar echo is assigned to a delimiting frame of an object detected on the basis of a camera, the delimiting frame being generated using the camera data by comparing corresponding azimuth angles and specified distances of the radar echo and the object detected on the basis of a camera. In the event of a successful assignment, a distance which is assumed on the basis of a camera is corrected according to the distance of the respective detected object in the surroundings, said distance being determined in a radar-based manner. The respective delimiting frame together with the corrected distance is then output as an object data set which indicates a successful object detection.

摘要： An object detection apparatus detects a target object present in a periphery of a moving body. The object detection apparatus derives recognition information indicating a state of a target object, and predicts a state of the target object at a next second observation timing, based on the recognition information derived at a first observation timing. The object detection apparatus derives a score based on a degree of difference between a state of the target object observed at the second observation timing and a next state of the target object predicted at the first observation timing. The object detection apparatus derives a reliability level by statistically processing scores related to the target object derived at a plurality of observation timings from past to present. In response to the reliability level satisfying a predetermined reference, the object detection apparatus determines that the target object related to the reliability level is actually present.
