As shown in fig.5, the flow chart of the method better embodiment moved for the image control 3 D positioning system that control centre of the present invention obtains according to camera.
Step 51, the control centre 18 receives the image included including antenna 14 to be measured that the camera 16 is obtained.
It is as shown in Figure 6 comprising the image including antenna 14 to be measured that the camera 16 is obtained, the largest image that first area 41 can collect for the camera 16, it is represented by dashed line, second area 42 is the image that the camera 16 gathers the antenna 14 to be measured in image, indicated by the solid line.
Step 52, the image of first area 41 is scanned according to scanning rule set in advance in the control centre 18, and one scan line columns is counted according to scanning result（Y ', X '）.
Specifically, for ease of understanding the present invention as, the first area 41 is regarded to n*m two-dimensional matrix.
In certain embodiments, as shown in fig. 7, the scanning rule can be：Scanned to the right since the 1st row the 1st row of the first area 41 to the 1st row m row, then scanned to the right since the 2nd row the 1st row of the first area 41 to the 2nd row m row, return again to and scanned to the right since the 3rd row the 1st row of the first area 41 to the 3rd row m row, the like, the every a line for scanning the first area 41 from left to right stops when scanning to the 1st pixel in the upper left corner of second area 42, total line number of the statistics of control centre 18 scanning and the columns of last column, are designated as the first scan line columns（Y1, X1）.
In certain embodiments, as shown in figure 8, the scanning rule can also be：The control centre 18 scans to line n the 1st and arranged to the left since the line n m row of the first area 41, then being scanned to the left to the (n-1)th row the 1st since being arranged the (n-1)th row m for the first area 41 arranges, return again to and scanned to the left since the n-th -2 row m row of the first area 41 to the n-th -2 row the 1st row, the like, the every a line for scanning the first area 41 from right to left stops when scanning to the 1st pixel in the lower right corner of second area 42, total line number of the statistics of control centre 18 scanning and the columns of last column, it is designated as the second scan line columns（Y2, X2）.

Distance=X '-X0 that second sliding block 121 is moved（1-1）
Distance=Y '-Y0 of 3rd sliding block 131 movement（1-2）
Work as X '-X0 for timing, show that the control centre 18 controls negative X-direction movement of second sliding block 121 to XYZ coordinate system, when X '-X0 is bear, show that the control centre 18 controls second sliding block 121 to be moved to the positive X-direction of XYZ coordinate system.
Work as Y '-Y0 for timing, show that the control centre 18 controls the 3rd sliding block 131 to be moved to the positive Y direction of XYZ coordinate system, when Y '-Y0 is bear, show that the control centre 18 controls negative Y direction movement of second sliding block 121 to XYZ coordinate system.
Step 56, the image size that the control centre 18 gathers according to the camera 16 calculates the distance that first sliding block 111 on the Z axis moving assembly 11 is moved on the Z axis linear slide rail 110.
Specifically, the control centre 18 using set in advance first apart from Z0 as gauged distance when, the first area 41 that the camera 16 is shot is standard area, and the total pixel number in SS region is S0.Described set in advance first can be apart from Z0, for example, 1.5 meters.
When the control centre 18 receives the image that the camera 16 is gathered, the total pixel number of statistics first area 41 is S ', and the control centre is according to following formula（2-1）Calculate the distance that first sliding block 111 is moved on the Z axis linear slide rail 110.
The distance that first sliding block 111 is moved=（S’/S0）*Z0 （2-1）
When S '/S0 is more than 1, show that the control centre 18 controls first sliding block 111 to be moved to the positive Z-direction of XYZ coordinate system, when S '/S0 is less than 1, show that the control centre 18 controls negative Z-direction movement of first sliding block 111 to XYZ coordinate system.
The image that control centre 18 of the present invention gathers according to the camera 16 calculates the sliding block（First sliding block 111, the second sliding block 121, the 3rd sliding block 131）Mobile distance, so as to change the distance between the antenna to be measured 14 and described transmitting antenna 15 and angle.
