Abrégé
(EN)
The present application discloses control apparatus for controlling application of line marking material to refurbish an old line pattern on a pavement surface, said control apparatus comprising a first line detector mounted in use at a forward position whereby a first predetermined width of said pavement surface substantially greater than said old pattern width is transverse scanned with information indicative of said old line pattern viewed by said first line detector being retained over a first predetermined length of said pavement surface in the direction of said old line pattern, a second line detector mounted in use rearwardly of said first line detector, said second line detector in use being arranged to transverse scan a second predetermined width of said pavement surface substantially greater than the width of said old line pattern with information indicative of said old line pattern viewed by said second line detector being retained over a second predetermined length of said pavement surface in the direction of said old line pattern, said first line detector producing a lateral shift control signal indicative of lateral shift of said old line pattern as sensed with said lateral shift control signal being adapted to control lateral movement of line marking material applicator to correctly deposit said line marking material over lines forming said old line pattern, said first line detector further recognising, preferably by a neural network, transition points in said old line pattern and providing signal indicative of said transition points to said second line detector, said second line detector including a transition detector which receives the signal indicative of transition points from said first line detector and information from the transverse scan of said second line detector and in response thereto provides a control signal to control on/off conditions of said line marking material applicator.
