An image generation apparatus includes a processor that generates an output image based on input images captured by multiple imaging units mounted on a paver including a hopper, a tractor, and a screed. The output image includes a hopper image representing a downward view of the hopper, a left-side surrounding image representing a downward view of a surrounding area on the left side in a movement direction of the paver, a right-side surrounding image representing a downward view of a surrounding area on the right side in the moving direction of the paver, and an illustration image of the tractor. The processor arranges the hopper image, the left-side surrounding image, the right-side surrounding image, and the illustration image such that the output image represents a downward view of the paver.

A line marking device (1) comprising a cart (2) with at least one steerable wheel (3) and at least two moving elements (4, 5). The steerable wheel (3) is rotatable around its axle (13) and pivotable such that the cart (2) is steered in a desired direction. The line marking device (1) comprises a GNSS receiver (7) or a robotic total station mounted on the cart (2). The line marking device (1) also comprises at least one spray nozzle (8), for marking a line, which is mounted on the cart and directed towards the ground below the line marking device (1). The device (1) comprises an interface mounted on the cart for a comparator to compare a detected location by the GNSS receiver (7) to a predetermined pattern. The cart (2) may comprise a motor (14) which is adapted to pivot the steerable wheel (3) towards an intended movement.

Location systems and methods for locating paint and other markings on a surface are described. More specifically, but not exclusively, the disclosure relates to smart paint stick devices and methods of use in locating and marking buried utility lines or other buried objects. One system for locating a buried object may include a buried object locator and a paint stick. The locator may include a tracking component configured to detect a location of a buried object. The paint stick may be configured to cause a paint container to dispense paint at a first position associated with the location of the buried object. The paint stick may include a position determination component configured to transmit one or more range vector signals that are detected by the tracking component. Sensors may be used to determine when paint is dispensed from a paint container, and to determine a color of the paint or a type of a marking.

A method of marking a line includes providing a line marking apparatus including a body (21), a line marking head (29) movable relative to the body, and a positioning system (35, 37, 41, 43) for determining a geographical location of the line marking head. In addition, a mathematical model is provided for a line to be marked by the line marking head, the model being cumulatively updated in response to a position fix (61) obtained by the positioning system. The position of the line marking head is adjusted relative to the body in dependence upon the mathematical model.

An installation system has a laser range finder set at a reference position to measure a distance to a target, an installation cart which performs operation for laying a magnetic marker in a road, and an arithmetic unit which identifies a position relation of a laying position where the magnetic marker is laid with respect to the reference position. When operation for laying the magnetic marker in a road is performed, by taking the installation cart during performing the operation of laying the magnetic marker in the road as a target, based on a distance to the installation cart measured by the laser range finder, the position relation of the laying position with respect to the reference position is identified by the arithmetic unit.

The present disclosure provides various aspects for mobile and automated processing utilizing additive manufacturing. The present disclosure includes methods for adding line features to a roadway surface. In some examples, the line features may include wires, conduits and electronic components. In some examples, the mobile additive manufacturing apparatus may create communication means into an advanced roadway in line features, which may be used for various communications including communications to and from autonomous vehicles. The communications may involve data related to the operation of systems of autonomous vehicles. In other examples, the line features may be dynamically colored with LED components.

A holder (1) for fixing a cylindrical spray can (2). The holder (1) comprises a holding unit (3) for fixing the spray can (2) with a first mechanical interface (4) for connecting a GNSS receiver (5) or prism to the holding unit (3). The holding unit (3) is adapted to hold the spray can (2) such that the GNSS receiver (5) or prism and the spray can (2) are arranged coaxially to each other. The holding unit (3) comprises a second mechanical interface (6) for releasably connecting the holder (1) to a frame (7) of a surveying cart (8).

Starting from a set of plans, such as, without limitation, blueprints, drawings, or Autocad® files, a system and method for calibrating such plans and transferring such plans into a computer readable file and loading a specially designed electronic version of such plans into a hardware based system that locates, adjusts, transfers, and prints, to a desired scale, a lasting image of said construction plans drawn onto a building surface.

A light emitter emits detecting light to a detecting area located outside a monitoring device. A light receiver detects reflected light that is generated in accordance with reflection of the detecting light by an object located in the detecting area. A first processor is capable of executing first detecting processing that is a part of information detecting processing for detecting information of the object based on the reflected light. A second processor is capable of executing second detecting processing that is a part of the information detecting processing, and is at least partially different from the first detecting processing. A controller changes a ratio of each of the first detecting processing and the second detecting processing to the information detecting processing.

A mobile platform for assessing and modifying pavement surfaces. An emitter generates electromagnetic waves towards a portion of a pavement surface. A condition sensor receives electromagnetic radiation from a first portion of the pavement surface and generates a first electronic signal representative of a current condition of the portion of the pavement surface. A location sensor generates a second electronic signal containing location data corresponding to the first portion of the pavement surface. A computing platform processes the electronic signals and creates a current pavement condition data point. The computing platform may compare the first electronic signal against a reference representative of a target condition, determine if there is a condition variance, and, if a condition variance exceeds a predetermined threshold, generate a condition control signal which is transmitted to and operates to modify operation of the pavement surface modification system in order to reduce the condition variance.
