Abstract
Abstract Apparatus for surveying a paved surface comprising a television camera mounted on a vehicle adapted to travel on the surface such that the camera has a field encompassing the paved surface, and a receiver for producing an image of the field viewed by the camera. A scale is on the surface of the screen of the receiver and by adjustment of the vehicle and the camera thereon, the image can be so located with respect to the scale to position the camera in a determined position. A road marking mechanism, such as for painting road lanes, can be mounted on the vehicle to mark the road surface at a specific location.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
179 words
An apparatus for surveying a paved surface having marginal edges separating the paved surface from the bordering unpaved surface, said apparatus comprising a vehicle, a television camera on said vehicle for viewing the vehicle and the paved and unpaved surfaces, a television receiver for receiving a signal from the camera and includng an image screen on which an image of the vehicle, the paved surface inclusive of its marginal edges, and the unpaved surface is received, a scale on said screen including a central mark and two lateral marks, paint applicator means on said vehicle, the arrangement of said vehicle, camera and marks being such that said marginal edges are aligned with said lateral marks and said applicator means with said central mark, and automatic control means operatively associated with said screen for detecting misalignment of the lateral marks and said marginal edges for correction of such misalignment and including photoelectric sensors adjacent said lateral marks for detecting shifting of the marginal edges relative to said lateral marks due to differences in brightness between the paved and unpaved surfaces.
Claim 2
Independent Claim
179 words
An apparatus for surveying a paved surface having marginal edges separating the paved surface from the bordering unpaved surface, said apparatus comprising a vehicle, a television camera on said vehicle for viewing the vehicle and the paved and unpaved surfaces, a television receiver for receiving a signal from the camera and includng an image screen on which an image of the vehicle, the paved surface inclusive of its marginal edges, and the unpaved surface is received, a scale on said screen including a central mark and two lateral marks, paint applicator means on said vehicle, the arrangement of said vehicle, camera and marks being such that said marginal edges are aligned with said lateral marks and said applicator means with said central mark, and automatic control means operatively associated with said screen for detecting misalignment of the lateral marks and said marginal edges for correction of such misalignment and including photoelectric sensors adjacent said lateral marks for detecting shifting of the marginal edges relative to said lateral marks due to differences in brightness between the paved and unpaved surfaces.
