If the modeling that is positioned at of construction to be measured position 6 outside surfaces indicates normal on the line 5 all on same surface level, then Laser Line Marker 3 is the horizontal laser light covering of the fan to the laser covering of the fan of the outside surface projection at construction to be measured position 6, and it is horizontal direction that modeling indicates line 5.
As shown in Figures 2 and 3; When the outside surface at construction to be measured position 6 is the axisymmetric hyperboloid geometrical body in center; The central shaft of the outside surface at construction to be measured position 6 is positioned on the plane at vertical laser covering of the fan 4 places, and thus obtained modeling indicates line 5 and is only effective modeling sign line.
If the central shaft of construction to be measured position 6 outside surfaces is a horizontal line, then Laser Line Marker 3 is the horizontal laser light covering of the fan to the laser covering of the fan of the outside surface projection at construction to be measured position 6, and it is horizontal direction that modeling indicates line 5.
In the mapping person can the scope of direct control, the present invention directly was placed on ground, flooring, building surface with Laser Line Marker 3, or Laser Line Marker 3 is installed in was placed on ground, flooring, building surface on the special-purpose tripod and indicates modeling and indicate line 5.
As shown in Figure 1, the present invention is installed in Laser Line Marker 3 to be placed on the special-purpose tripod and indicates modeling sign line 5 on the building flooring.
In the mapping person can not the scope of direct control, the present invention was installed in Laser Line Marker 3 and indicates modeling on the aid and indicate line 5.
As shown in Figure 3; The mapping person can not direct control and the position of Laser Line Marker 3 be higher than under the situation of mapping person position; The present invention is fixed on Laser Line Marker 3 on the aid I; Rise aid I; After making Laser Line Marker 3 be increased to predetermined graticule height, utilize 3 rotations of aid I control Laser Line Marker to arrive predetermined graticule location mark modeling and indicate line 5, realize the modeling that is higher than the construction to be measured position 6 that mapping person position, mapping person can not direct control is indicated the sign of line 5.Among the present invention, aid I has the elevating lever of rotatable motion bar except using top as shown in Figure 3, also can Laser Line Marker 3 be placed predetermined graticule position by means such as scaffold erecting.
As shown in Figure 2; The mapping person can not direct control and the position of Laser Line Marker 3 be lower than under the situation of mapping person position; The present invention is installed in Laser Line Marker 3 on the aid II; Utilize aid II that Laser Line Marker 3 is dropped to predetermined graticule location mark modeling and indicate line 5, realize that the modeling that is lower than the construction site that mapping person position, mapping person can not direct control is indicated line to indicate.Likewise, employed aid II also can place predetermined graticule position with Laser Line Marker 3 by means such as scaffold erecting among the present invention except can be liftable support as shown in Figure 2.
(2) target of digital building mapping method photography link of the present invention is to utilize camera 2 to take the graticule modeling photo at construction to be measured position 6.
Taking the preliminary work that needs to accomplish before the graticule modeling photo comprises: in the viewfinder range of intending the construction to be measured position of taking 6, obtain two groups of line segments; Specifically; The every group of line segment that is obtained constitutes by two line segments; These line segments are horizontal line or vertical curve, and two line segments in same group of line segment are parallel to each other, and on the same group line segment is then not vertical each other; Perhaps; In the viewfinder range of intending the construction to be measured position of taking 6, obtain the anchor point of two groups of line segments; Likewise; The anchor point that is obtained should meet the following conditions: the connecting line of these anchor points is horizontal line or vertical curve, and the connecting line of the anchor point in same group is parallel to each other, and on the same group the connecting line of anchor point is then not vertical each other.

(5) draw corresponding geometric figure according to the said form dimension of step (2); With this geometric figure is the said photo of modeling size reference plane convergent-divergent step (3); Photo behind the convergent-divergent and this modeling size reference plane are complementary, and serve as according to the three-dimensional model of setting up said construction to be measured position with the photo behind the convergent-divergent;
(6) serve as according to the elevation of building schema mapping that generates the construction to be measured position with the said three-dimensional model of step (5).
2. a digital building mapping method that is used to obtain the elevation of building schema mapping is characterized in that comprising the steps:
(1) fixing self leveling Laser Line Marker; Utilize outside surface projection level or the vertical laser covering of the fan of this Laser Line Marker to the construction to be measured position; The outside surface at said laser covering of the fan and construction to be measured position intersects the formation modeling and indicates line; The outside surface at said construction to be measured position is the axisymmetric hyperboloid geometrical body in center, and the central shaft of the outside surface at said construction to be measured position is positioned on the plane at laser covering of the fan place;
(2) in the viewfinder range at the construction to be measured position of intend taking, obtain the anchor point of two groups of line segments or two groups of line segments, every group of line segment contains two line segments that are parallel to each other, and said line segment is horizontal line or vertical curve, and on the same group line segment is not vertical each other; Obtain a plane of intersecting with the construction to be measured position, this plane is vertical with said laser covering of the fan, in this plane, obtains a geometric figure again or constitutes geometric anchor point, measures and draws the required form dimension of said geometric figure;
(3) fixing camera; Utilize this camera to take the photo at said construction to be measured position; Show said modeling in the said photo and indicate line; And show the anchor point of said two groups of line segments or two groups of line segments in the said photo, also show said geometric figure in the said photo or constitute geometric anchor point;
(4) using modeling software, is foundation with the anchor point of two groups of line segments in the said photo or two groups of line segments, the perspective relation of adjustment scene modeling so that the perspective relation at the construction to be measured position in the perspective relation of this scene modeling and the said photo mate;
(5) draw corresponding geometric figure according to the said form dimension of step (2); With this geometric figure is the said photo of modeling size reference plane convergent-divergent step (3); Photo behind the convergent-divergent and this modeling size reference plane are complementary, and serve as according to the three-dimensional model of setting up said construction to be measured position with the photo behind the convergent-divergent;
(6) serve as according to the elevation of building schema mapping that generates the construction to be measured position with the said three-dimensional model of step (5).
