Fig. 1 is a schematic structural view of the present utility model.
1, a first fixed ruler; 2. a first movable scale; 3. a first set screw; 4. a fixed ruler; 5. a spraying area; 6. a second set screw; 7. a second fixed rule; 8. a second movable ruler.
Description of the embodiments
The utility model is further illustrated by the following examples:
the utility model provides an aerial photogrammetry image control point lays spraying marking plate, as shown in fig. 1, including fixed chi 4 and with fixed chi 4 swing joint's removal chi, fixed chi 4 includes the first fixed chi 1 and the second fixed chi 7 of perpendicular setting, all be equipped with the scale on first fixed chi 1 and the second fixed chi 7. The length dimension and the width dimension of the spraying area 5 are conveniently and accurately measured by setting scales so as to accurately measure the dimension of the spraying area 5.
The movable ruler comprises a first movable ruler 2 and a second movable ruler 8, the first movable ruler 2 moves left and right in the horizontal direction along a second fixed ruler 7, the second movable ruler 8 moves up and down in the vertical direction along a first fixed ruler 1, and the imaging control points are distributed in a spraying area 5 enclosed by the first fixed ruler 1, the second fixed ruler 7, the second movable ruler 8 and the first movable ruler 2. The fixed positions of the first movable ruler 2 and the second fixed ruler 7 and the fixed positions of the second movable ruler 8 and the first fixed ruler 1 are respectively determined according to the length and the width dimensions in the spraying area 5.
After the positions of the first movable ruler 2 and the second fixed ruler 7 are fixed, the first movable ruler 2 and the second fixed ruler 7 are fixed through the second fixed screw 6; after the second movable ruler 8 is fixed with the first fixed ruler 1, the second movable ruler 3 is fixedly connected with the first fixed ruler 1 through the first fixed screw 3.
