Claim 3
Dependent Claim
79 words
2 A system according to claim 1, characterized in, that a first part of said video cameras is directed substantially in the direction of travel of said vehicle, and the remaining second part thereof is directed transversally thereto, the video frames originating from said first part being recorded, on said first medium, in series in a regularly alternating succession, the video frames originating from the second part being recorded on said medium between successive series of said first frames.
Claim 4
Dependent Claim
78 words
System accoording to claim 1, characterized in, that the metric data in said data base are organised according to chains interconnecting numbered nodal points, said vehicle being provided with signalling means to be actuated by an attendant as soon as the vehicle has reached a point on its route corresponding to a nodal point indicated by said data base, in order to set the data recording apparatus on a new chain starting point corresponding to said nodal point.
Claim 5
Dependent Claim
