摘要： A preview road surface detection device of a vehicle of the present invention includes: a distance sensor that is disposed in a vehicle member and detects a distance to a measurement point on a road surface nearer to a front part of the vehicle, corresponding to at least a central portion of a contact patch to the road surface of a wheel of the vehicle; and a distance calculator that calculates a road surface distance from the vehicle member to the measurement point, based on a value detected by the distance sensor. A displacement of the road surface nearer to the front part of the vehicle is detected as a road surface condition. The displacement of the road surface is calculated from the road surface distance and a vehicle height of the vehicle member when the distance sensor detects the distance.

摘要： A method of monitoring quality of a road segment from driver data is provided. The method includes receiving, by a server over a network, the driver data for a road segment from one or more sensing units in one or more vehicles. The method also includes calculating, in one or more computing devices, one or more quantitative pavement surface characteristics of the road segment from the driver data using a probabilistic inverse analysis framework. The method also includes identifying, in the one or more computing devices, one or more quantitative vehicle properties of the one or more vehicles from the driver data using the probabilistic inverse analysis framework. The method then includes estimating, in the one or more computing devices, one or more road quality characteristics of the road segment based on at least one of the quantitative pavement surface characteristics of the road segment and the quantitative vehicle properties of the one or more vehicles.

摘要： Target point cloud data about a specific road are extracted from perimeter point cloud data acquired by moving a road surface measurement device along a measurement route and scanning the surroundings thereof. A data storage unit stores trajectory point sequence data that represent, as a plurality of trajectory points, the perimeter point cloud data and a trajectory of the movement of the road surface measurement device. A trajectory point sequence setting unit acquires a trajectory point sequence at equal intervals from the trajectory point sequence data. An extraction area setting unit sets, as extraction areas, a column area Ci and a parallelepiped area Hi that are geometric areas disposed at predetermined positions below a trajectory point Xi. An approximate nearest neighbor search processing unit and an extraction processing unit extract, as the target point cloud data, point data that belong to this extraction area of the perimeter point cloud data.

摘要： A soil monitoring system for an agricultural tillage implement includes a sensor configured to be coupled to a frame of the agricultural tillage implement. The sensor is configured to be directed toward a region of a soil surface. In addition, the sensor is configured to emit an output signal toward the region of the soil surface and to receive a return signal indicative of a profile of the soil surface within the region. Furthermore, the soil monitoring system includes a controller configured to identify a rough soil profile in response to determining that at least one variation in the profile of the soil surface within the region is greater than a first threshold value, and/or in response to determining that a number of variations in the profile of the soil surface within the region is greater than a second threshold value.

摘要： A method for determining shape deviations of a real actual surface on the basis of measured vertical information of measurement points of the actual surface section is provided. Measurement points are located in a measurement-point extent section, wherein the method uses evaluation sections, which are arranged at offsets to each other and, altogether, extend over the measurement-point extent section. The method includes (a) for each measurement point of a number of measurement points of each evaluation section of the first evaluation sections, determining a maximum vertical distance that results as the greatest distance in a specified vertical direction between two measurement points, and (b) determining an evaluation-section slope, which represents a straight connecting line between an evaluation-section lowest point and an evaluation-section highest point, wherein, in a further step, the value pairs of a maximum vertical distance and of an evaluation-section slope, which value pairs are determined in a plurality of iterations for the respective evaluation sections thereof, are associated with a limit criterion.

摘要： Electronic trowels, systems and methods of applying a layer of material using the present electronic trowels. The various electronic trowels include a handle, at least one blade, and one or more sensors residing on or within the trowel. The trowel is for applying a layer of material over a surface area, whereby the one or more sensors detect and collect material installation data during application of the layer of material over the surface area. One or more electronic devices coupled to the one or more sensors receive and analyze the collected installation data for monitoring and controlling the application of the layer of material to ensure a desired end product is achieved. Application errors may be detected before, during, or after the installation process.
