Abstract:
1. A road surface scanning device, comprising: a frame having a plurality of structural members including a longitudinal support that extends in a longitudinal direction of the scanning device, and a lateral support that extends in a lateral direction of the scanning device and is securely connected to the longitudinal support; a carriage being movably attached to the frame so that it can move in the longitudinal direction of the scanning device; a scanner for acquiring road surface data and having a laser head that emits an incident laser line towards the road surface, and a camera that receives a reflected laser line from the road surface; a first actuator for moving the scanner along the carriage in the lateral direction of the scanning device; and a second actuator for moving the carriage along the frame in the longitudinal direction of the scanning device, wherein the first actuator moves the scanner along the carriage during a lateral scan, and the second actuator moves the carriage along the frame in between lateral scans.
