摘要： The twist of a railway track (36) can be measured with a vehicle which includes a frame (25). This frame (25) carries a roll sensor (40) to measure the rate of roll (w) about a longitudinal axis, and sensors (38) to monitor the variations in the relative tilt between the frame (25) and the rails (35). The signals from these sensors (38) and (40) enable the changes in cant (Δc) between one instant and the next to be determined, and so the twist of the track can be calculated by summing successive changes in cant. This method of determining twist can operate at substantially any vehicle speed, and gives consistent measurements in real-time.

摘要： Systems and methods for determining a trend in vertical track modulus are disclosed in accordance with embodiments of the present invention. Vertical deflection data is collected along a particular section of railroad track. A first set of vertical track modulus is determined, based in part, on the collected vertical deflection data. At a second time, vertical deflection data is again collected along the particular section of railroad track to be used in determining a second set of vertical track modulus. At least the first and second sets of vertical track modulus are analyzed to determine a mathematical algorithm that facilitates developing a trend in the vertical track modulus of the railroad track.

摘要： A lidar and digital camera system collect data and generate a three-dimensional image. A lidar generates a laser beam to form a lidar shot and to receive a reflected laser beam to provide range data. A digital camera includes an array of pixels to receive optical radiation and provide electro-optical data. An optical bench passes the laser beam, reflected laser beam, and optical radiation and is positioned to align each pixel to known positions within the lidar shot. Pixels are matched to form a lidar point-cloud which is used to generate an image.

摘要： The mobile data collection system includes a positioning system, such as a Global Positioning System (GPS) receiver and/or an Inertial Navigation System (INS), to generate position and time data. A down looking line scan camera for mounting on a vehicle, obtains a series of line scan images of a path, such as a road. A data collection controller is connected to the positioning system and the line scan camera to associate the line scan images with the corresponding position and time data. A database stores the line scan images and associated corresponding position and time data. An image processor identifies and marks features in the line scan images.

摘要： There is provided a vision system and a method for scanning a traveling surface such a road to detect surface defects thereof such as cracks. The vision system, which is mountable on a vehicle, is provided with a linear imaging system for imaging successive adjacent transversal linear portions of the traveling surface as the vehicle advances. The vision system is also provided with laser line projecting means angularly projecting a laser line onto the transversal linear portion of the traveling surface to be imaged in a substantially coplanar relationship with the linear imaging system. The present vision system is particularly devised to be immune to surrounding light conditions variations to provide optimum cracks image contrast for both transverse and longitudinal cracks.

摘要： A surface profiler comprises at least one mass resiliently supported in relation to the frame of the profiler to exert a downward force opposing upward movement of the frame when the wheels pass over an obstacle. Two such masses may be constrained for substantially vertical movement by tie rods extending from pivoting suspension bars secured on distal portions of the frame. A pivoting bracket optionally connects to a handle or to a motor drive unit for propelling the apparatus. The bracket is pivoted about the center point of a line joining the centers of the wheel axles to avoid any torque on the apparatus as a result of operator manipulation.

摘要： A measurement block 10 which moves longitudinally on a road surface includes disk-shaped first, second, and third rollers 11, 12, and 13 having the same outer diameter with a predetermined spacing set therebetween, a first coupling rod 14 which is mounted on rotary shafts of the first and second rollers in a revolving manner, a second coupling rod 15 which has the same length as the first coupling rod and which is mounted on rotary shafts of the second and third rollers in a revolving manner, a distance measurement device 16 which is mounted on the rotary shaft of the first or second roller, and a rotary encoder 18 which is mounted on the second coupling rod to detect an angle between the first and second coupling rods. Each time the measurement block moves by a length between the first and second coupling rods, the angle between the first and second coupling rods is detected by the angle detection means to thereby create a longitudinal profile based on the detected value.
