Difficulty is taken photo by plane using unmanned plane 1, can effectively be shot harbour, different location ship and harbour surrounding scene and be recorded, real
When monitoring field angle α in ship state, with fast and flexible, mobility is strong, characteristic of high reliablity, reach quickly law enforcement,
It collects evidence believable effect.Change the flying height of unmanned plane 1, can flexible choice need the more of the ship covered in monitoring image sum
It is few, can disposably shoot the ships of more stops, the location information that every ship is stopped can obtain, effectively reduce it is artificial and
Time cost, to overcome evidence obtaining according to insufficient defect, in addition, unmanned plane 1 is adapted to the severe rings such as high wind, strong rain
Border can be carried out law enforcement at any time.
Step S3, information transmission modular 4 hang down high data by real time video image and in real time respectively in the form of wireless signal
It is transferred to ground control terminal 5.
By information transmission modular 4, the real-time height that hangs down of the video image of shooting, measurement is back to ground control terminal 5, it can
It observes the information such as each object space, size under high angle shot visual angle, and can be carried out image data preservation, be convenient for historical query.
Step S4, the ground control terminal receive dotted line signal;
Step S5 hangs down high data in the form of data connection by the received real time video image of ground control terminal 5 and in real time
It is transferred to monitor terminal 6, monitor terminal 6 carries out video image calling, horizontal distance calculates and the production of picture and text evidence, wherein view
Frequency image call is to call video image by video image calling module 62 and be shown in display screen 61;Horizontal distance calculates
It is to calculate the offshore distance X of ship by carrying out electronic surveying calculating to high angle shot video image, it is quasi- can effectively to improve measurement
Exactness improves efficiency.It includes following substeps that horizontal distance, which calculates, firstly, the vertical high and image that the high inductor 3 that hangs down is measured is adopted
The angle input level distance calculation module 63 of the field angle α of storage 2;Secondly, horizontal distance computing module 63 calculates image view
Boundary always away from, in this step, as shown in Fig. 2, according to Chui Gao and field angle, using the cosine law calculate image perspectives always away from.
In Fig. 2, AC is that image perspectives always hang down away from, it is known that the field angle α of image acquisition device 2 and in real time in 2 field angle α of image acquisition device
High H, then L=tan α × H, | AC |=2 × L;Finally, accounting for the ratio of image perspectives, water using the length between ship and harbour
Flat distance calculation module Ship ' between harbour at a distance from.As shown in Fig. 2, X indicate dock vessels outermost or most inner side with
The distance of wharf edge, occupies according to X | AB | ratio, can obtain dock vessels at a distance from harbour, i.e., the offshore of ship away from
From X, and judge whether stop violating the regulations.
Step S6, picture and text evidence are made by picture and text evidence production module 64 and will shoot image, shooting time, and shoot and hang down
Process on the elements combinations a to picture such as high and horizontal distance calculated result, the process can be used but be not limited to screenshotss operation
It is achieved.Step S43 provides convictive foundation for law enforcement, and law enforcement is made to have card can be according to.
Distance measuring method of taking photo by plane provided in this embodiment for ship berthing management can greatly improve law enforcement efficiency, reduce
Human and material resources cost, and measurement error can be reduced by algorithm.
In the present embodiment, step S5 video image calling module calls video image by OpenCv function library.
In the present embodiment, Ship ' in step S5 between harbour at a distance from, apply dual-cache mechanism, regarded in image
Two monitoring interface scale lines 7 are drawn on the upper layer on boundary, drag the outermost of monitoring interface scale line 7 to required measurement ship respectively
With corresponding wharf edge, the ratio of image boundary overall length is occupied by calculating two monitoring interface scale lines 7, obtains two monitoring
The distance between interface scale line 7 is the distance between dock vessels and harbour, i.e. offshore distance, as shown in Fig. 2, two monitoring
The distance between interface scale line 7 X is the offshore distance of ship.
Embodiment 3
As shown in Figure 1, Figure 2 and Figure 4, the another kind that embodiment 3 provides is used for the distance measuring method of taking photo by plane of ship berthing management,
It is improved by embodiment 2, method and 1 fundamental form of embodiment are same, and only improvement part is described below.
In the present embodiment, if in step S5, the distance between dock vessels and harbour (offshore distance X) are more than ship
Security alert distance in pool regulation then executes the step the production of S6 picture and text evidence;If offshore distance X is less than ship berthing rule
Security alert distance in fixed then makes (being not processed) without picture and text evidence.
In the present embodiment, distance measuring method of taking photo by plane for ship berthing management further includes that step S7 picture and text evidence saves,
It is that the picture and text evidence to complete in picture and text evidence production module 64 is stored in picture and text evidence to save mould that picture and text evidence, which saves,
Block 65.
In the present embodiment, step S5 picture and text evidence is with the preservation of jpg or bmp format.
In the present embodiment, the preservation of step S5 picture and text evidence can also be saved video recording, and save video with avi format
Image.
