Abstract
Abstract A doppler radar vehicle speed measurement template is provided with a representation of the photograph zone intersecting with a horizontal line representing the horizon of the road and a vertical line representing the vertical plane of the optical axis of the camera. The template is laid over the photograph with the vertical and horizontal lines aligned with the center of the photograph and with either the vanishing point of the road or a point at the height of the camera to accurately locate the vehicle in the photograph zone.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
78 words
An apparatus for locating a vehicle on a road in the photograph zone of a photograph of a doppler radar speedmeasuring apparatus having a central perspective representation of the photograph zone thereon, a vertical line representing the vertical plane of the optical axis of the apparatus thereon, and a horizontal line representing the horizon of the road plane thereon, said vertical line, horizontal line and the vanishing point of said photograph zone representation intersecting at a common point.
Claim 2
Independent Claim
78 words
An apparatus for locating a vehicle on a road in the photograph zone of a photograph of a doppler radar speedmeasuring apparatus having a central perspective representation of the photograph zone thereon, a vertical line representing the vertical plane of the optical axis of the apparatus thereon, and a horizontal line representing the horizon of the road plane thereon, said vertical line, horizontal line and the vanishing point of said photograph zone representation intersecting at a common point.
Claim 3
Dependent Claim
19 words
An apparatus as set forth in claim 1 wherein said representation and said lines are on a transparent template.
Claim 4
Dependent Claim
29 words
An apparatus as set forth in claim 2 wherein said template further includes a second representation of the photograph zone symmetrically of the vertical line from the first representation.
Claim 5
Dependent Claim
38 words
An apparatus as set forth in claim 2 wherein said template includes supplementary marks set symmetrically relative to the perpendicular middle of the photograph on a horizontal line for lateral centering of said template relative to the photograph.
Claim 6
Dependent Claim
34 words
An appaRatus as set forth in claim 4 wherein said template further includes a grating of horizontal parallel lines parallel to an edge of the photograph for moving said template parallel to said edge.
Claim 7
Dependent Claim
119 words
Apparatus for the evaluation of photographs taken with a camera having an azimuth fixedly related to a doppler radar speed-measuring system having a radar antenna whereby the optical axis of the camera lies in a vertical plane extending through the axis of the direction characteristic of the radar antenna; said apparatus comprising a central perspective representation related to the location of the camera of a specific photozone fixedly related to the doppler radar speed-measuring system and to a road without a marking of the road, said central perspective representation further including representations of the horizon of the road, said vertical plane through the optical axis of the camera and the axis of the direction characteristic of the radar antenna.
Claim 8
Dependent Claim
119 words
Apparatus for the evaluation of photographs taken with a camera having an azimuth fixedly related to a doppler radar speed-measuring system having a radar antenna whereby the optical axis of the camera lies in a vertical plane extending through the axis of the direction characteristic of the radar antenna; said apparatus comprising a central perspective representation related to the location of the camera of a specific photozone fixedly related to the doppler radar speed-measuring system and to a road without a marking of the road, said central perspective representation further including representations of the horizon of the road, said vertical plane through the optical axis of the camera and the axis of the direction characteristic of the radar antenna.
Claim 9
Dependent Claim
25 words
An apparatus as claimed in claim 6 further including representation of the photozone symmetrical to said central perspective representation with respect to a vertical axis.
Claim 10
Dependent Claim
43 words
An apparatus as claimed in claim 6 wherein said central perspective representation is on a template and marks are applied on said template symmetrically to the center vertical line of the photograph for laterally aligning said template on the photograph to be evaluated.
Claim 11
Dependent Claim
21 words
An apparatus as claimed in claim 8 wherein said template further includes a grating parallel to the edges of the photograph.
