Abstract: An apparatus for locating, inspecting, or placing marks on a roadway. The apparatus includes a GPS-based machine vision locator for sampling discrete geographical location data of a pre-existing roadway mark evident on the roadway. A computer may determine a continuous smooth geographical location function fitted to the sampled geographical location data. A marker is responsive to the GPS-based locator and geographical location function for replicating automatically the pre-existing roadway mark onto the roadway. The apparatus is typically part of a moving vehicle. A related method is disclosed for locating, inspecting, and placing marks on a resurfaced roadway. A similar apparatus can be used to guide a vehicle having a snow plow along a snow-covered roadway, or a paving machine along an unpaved roadway surface. The apparatus provides for accurate determination of roadway mark locations, roadway mark inspection apparatus and roadway markers using Bayesian model-based filtered enhanced GPS geographical location data.

Abstract: A control system for positioning a marker over a pre-existing roadway surface mark. The control system has an electromagnetic radiation source attached to the marker for producing a mark pattern on the roadway surface. An imager permits the control system to image both the pre-existing roadway surface mark and the mark pattern produced by the electromagnetic radiation source. A computer is responsive to the imager for producing an error signal based upon the location difference between (a) the image of the pre-existing roadway surface mark and (b) the image of the mark pattern produced by the electromagnetic radiation source. An actuator is responsive to the error signal for positioning the marker over the pre-existing.

Abstract: A field programmable controller for controlling the components of roadway marking equipment mounted on a vehicle. The controller includes a general-purpose computer and a microcontroller for controlling and monitoring roadway marking equipment and which further maintains the operational state of the roadway marking equipment during reprogramming of the microcontroller. A wireless transceiver in communication with the internet for receiving software update data is also included. Finally, the controller has a configurable state machine responsive to the microcontroller and configured for: defining the start-up operational state of the components; maintaining a predetermined operational state of the components during the time the computer and microcontroller is being reprogrammed with software update data; and maintaining the operational state of the components for normal operation.
