摘要： A method for detecting obstacles for a rail vehicle includes capturing 3D image data from an area surrounding the rail vehicle and generating 2D image data from the 3D image data. Rails are detected and localized in the 2D image data. Depth data are determined in the 2D image data based on the 3D image data. The 2D image data are divided into linear image segments, each having a rail section with a constant depth. A depth value of a pixel of a linear image segment outside the rails is then compared with the respective depth value of the rails. If the difference between the depth value of the pixel and the depth value of the rails exceeds a threshold value, the pixel is part of an object projecting above the level of the terrain. Depending on its position and/or movement, the object is considered a potential collision obstacle.

摘要： Systems and methods for rails and obstacles detection based on forward-looking electrooptical imaging, novel system architecture and novel scene analysis and image processing are disclosed. The processing solution utilizes a deep learning semantic scene segmentation approach based on a rails and switches states detection neural network that determines the railway path of the train in the forward-looking imagery, and an objects and obstacles detection and tracking neural network that analyzes the vicinity of the determined railway path and detects impending obstacles.

摘要： The invention relates to a method for determining an actual position of rails of a track by means of an optical sensor device, positioned on a rail vehicle, for recording the position of the track and adjacent installations. In this, it is provided that, by means of the sensor device, a course of the track and a course of the adjacent installations, in particular a catenary installation, are recorded for a track section as preliminary actual data, and that the preliminary actual data are transformed into corrected actual data in an evaluation device in that a recorded course of at least one adjacent installation is transformed into a course with a specified geometric shape. In addition, the invention relates to a system for implementing the method.

摘要： An article transport vehicle that travels along a traveling path is provided with an obstacle sensor that detects an obstacle that exists in a detection area, and a control unit that controls the traveling speed of the article transport vehicle based on detection information of the obstacle sensor. A non-detection area where detection of the obstacle by the obstacle sensor is not performed is set within the detectable area of the obstacle sensor, and a situation in which the non-detection area exists on a detection line that joins a part of the detection area and the obstacle sensor is defined as a specific situation. The control unit, in the specific situation, and a situation where an undetectable area in which it is not possible to detect the obstacle exists in the detection area because a shield exists in the non-detection area, reduces the speed of the article transport vehicle to a second traveling speed slower than the first traveling speed.

摘要： A recording unit records an installation position of a ground installation object and an installation identifier of the ground installation object for each of a plurality of the ground installation objects installed beside a track on which a vehicle of a track transport system mounted with an external sensor travels; an installation object recognition unit specifies the installation identifier from external sensor information including information detected by the external sensor and recognizes the ground installation object corresponding to the installation identifier by referring to the recording unit; and a detection distance calculation unit calculates a detection distance of the external sensor. The detection distance calculation unit calculates the detection distance of the external sensor from a self-position of the vehicle at which the ground installation object is recognized and the installation position of the ground installation object recognized by the installation object recognition unit.

摘要： A method for monitoring a danger area of a railway installation. At least one radio module is arranged in, or in the vicinity of, the danger area. Radio signals are transmitted by the radio module and the radio signals are received and evaluated. A pattern of the received radio signals in a basic state of the danger area is determined and when the radio signals are evaluated, differences from the pattern in the basic state are determined and a response is triggered when the differences exceed a predefined limit value. There is also described a monitoring device. The radio modules are preferably WLAN modules and the danger area is a tunnel. Timetabled breaches of the danger area by trains do not lead to an alarm and the radio modules are functionally tested by determining whether the predefined limit value is exceeded when a train travels through.

摘要： A system and method for automating railroad maintenance by a tie gang using electronic tie marking (ETM) configured to optimize railroad asset maintenance. The system enables collision avoidance between members of the tie gang performing maintenance on railway assets (e.g., Rails, Ties, Ballasts, Turnouts, Crossings, etc.). The system can generate production numbers for the railway assets and evaluate an asset queue for the tie gang to perform maintenance. The system can utilize real-time updates from the tie gang to optimize work output. The system can provide a customizable user interface to identify, track, and process information related to maintenance of the railroad asset. The system also provides for a heads-up-display (HUD) to notify an operator of relevant information, such as maintenance information, travel indicators, and updated asset queue. The system can identify a next location and calculate an optimum path based on sensor input incorporating machine-specific and environmental characteristics.

摘要： An object of the present invention is to provide an obstacle detection system and an obstacle detection method for a trajectory traveling vehicle, which are capable of detecting a front obstacle on a trajectory and around the trajectory with high accuracy. The system includes: a monitoring area setting processing unit that sets an obstacle monitoring area for detecting an obstacle; a front obstacle monitoring unit that monitors an obstacle in the obstacle monitoring area using a sensor that horizontally scans the front of the train; and an obstacle detection unit that detects an obstacle in the obstacle monitoring area based on a monitoring result by the front obstacle monitoring unit, in which the front obstacle monitoring unit complements a gap in a detection region of the sensor at a first position with a detection region of the sensor while the train moves from the first position to a second position.
