Ring, positioned at innermost circle outer profile and be located in the middle circle between constitute the 2nd annulus, two pieces of rectangular slabs, the 1st circle
Ring, the inner circle color be the first color, the 2nd annulus and the cross are the second color, first color and the
One is dark color in second colors, and one is light color.
Above-mentioned outer diameter of a circle is 20cm, and intermediate diameter of a circle is 13cm, and interior diameter of a circle is 6cm.
The length of above-mentioned two pieces of rectangular slabs is 20cm, width 3cm.
In one embodiment of the utility model, first color is black, and second color is white.
In another embodiment of the utility model, first color is white, and second color is black.
In another embodiment of the utility model, first color is white, and second color is big ground colour.
Above-mentioned sign board can be board or metal board, and when use, which is disposed at, needs to be arranged the position of the sign board i.e.
It can.Alternatively, it is also possible to which the pattern of sign board is directly sprayed on the position that ground etc. needs to be arranged the sign board with spray form.
The combination of the sign board of the utility model, concentric circles and crosshair is conducive to the precision for improving photo control point thorn point, mentions
The high operating efficiency of field operation thorn point personnel；On the one hand the discrimination of image, another party can be improved in the addition of two rectangle frames
The accurate match of image photo control point can be improved in face, and then improves the precision of image processing.The sign board makes and using quick
Convenient, image definition substantially increases the efficiency of unmanned plane photo control point laying, identifies convenient for unmanned plane.
