The device that navigates includes navigation camera 4, caliberating device（It is not shown）And display device（It is not shown）, wherein, the navigation camera 4 is located at
The top of objective table 3, the navigation picture of captured in real-time one please refers to Fig. 2, is the top view of scaling board of the present invention, demarcation dress
Put including scaling board 5 and computing module, scaling board 5 is provided with some calibration points（Including the first calibration point 51, the second calibration point 52
With the 3rd calibration point 53）, the scaling board 5 is positioned on the objective table 3；The mobile x-ray detector 1, should to some calibration points
Computing module record the x-ray detector 1 movement physical coordinates and to should be on navigation picture navigation coordinate, calculate physics seat
The corresponding relation of mark and the navigation coordinate；The display device connects the navigation camera 4 and the x-ray detector 1, shows the navigation picture
With the realtime graphic under the x-ray detector visual field, and in clicking on any navigation on the navigation picture in the display device
During coordinate, the x-ray detector 1 is moved to above the corresponding physical coordinates.
In the present embodiment, the physical coordinates that the caliberating device also records any calibration point are the original of the x-ray detector
Point coordinates, and when the x-ray detector is moved to the origin, the navigation camera shoots the navigation picture.
The air navigation aid of the present invention includes：
