Height of the height at least equal to lamp.Currently, the irradiating angle measurement of ship navigation lamp is all the mode circular by barge, and in ship
Oceangoing ship shakes down to anchorage when progress, or carries out in ship landing pier.Trial voyage is needed by barge with row to anchorage, and
Harbour needs tested turn-round of ship to turn to the navigation lights angle measurement that could complete port and starboard both sides.No matter which kind of method, expend
Manpower and material resources it is very big, and influenced by weather also larger.Target in measurement process outside one nautical mile of naked-eye observation, also can be because
The visibility of weather is bad or unrestrained height causes the inaccuracy of range estimation.
Summary of the invention
A kind of measurement of ship navigation lamp irradiating angle is provided it is an object of the invention to overcome the deficiencies of existing technologies
Method, it surround new ship measurement navigation lights irradiating angle instead of traditional barge, more convenient, save and measure
Accurately.
The object of the present invention is achieved like this: a kind of measurement method of ship navigation lamp irradiating angle, using unmanned plane
Measure and the following steps are included:
Step 1 opens the navigation lights of tested ship, closes the other boat lamps and harbour lamp of tested ship；
Step 2 installs camera and infrared lamp on unmanned plane, and guarantees the irradiating angle and infrared lamp of camera
Irradiating angle is identical, unmanned plane of then taking a flight test, and whether the light point of irradiation for observing infrared lamp is located at the center position of camera shooting
It sets；
Step 3, positioning unmanned plane are the coordinate of the navigation lights in the top of the navigation lights of tested ship；
Step 4 first operates at unmanned plane during flying to the set distance L away from navigation lights, and makes the height and navigation of unmanned plane
The height of lamp is consistent, then adjusts the flight angle of unmanned plane, until the light of the infrared lamp on unmanned plane is beaten in navigation lights
One side barn door edge, the position of the unmanned plane is set as initial position, and record the coordinate of the initial position；
Step 5, according to irradiating angle as defined in navigation lights planning unmanned plane flight path, i.e., using navigation lights as the center of circle,
It is drawn and is justified as radius using set distance L, which is the flight path of unmanned plane；
Step 6, unmanned plane fly according to the flight path of planning, and camera energy should be kept during unmanned plane during flying
The light of navigation lights is observed, and the light of infrared lamp is radiated on navigation lights, when camera can not observe navigation lights
When the light of light or infrared lamp is radiated at the another side barn door of navigation lights, stop unmanned plane, by the stop position of unmanned plane
It installs as final position, and records the coordinate of the final position；
Step 7, according to the seat of the final position of the coordinate and unmanned plane of the initial position of the coordinate of navigation lights, unmanned plane
Mark calculates the irradiating angle of navigation lights.
The measurement method of above-mentioned ship navigation lamp irradiating angle, wherein the unmanned plane use can carry camera
Large-scale unmanned plane, flight operations distance are 2 kilometers or more, and the follow-on mission time is more than half an hour.
The measurement method of above-mentioned ship navigation lamp irradiating angle, wherein the set distance L is at least 1 kilometer.
The technical solution of the measurement method of ship navigation lamp irradiating angle of the invention, measures ship using unmanned plane
Navigation lights irradiating angle can both guarantee mechanical measurement and calculate instead of bring convenience and accuracy after gross visualization, greatly
Type unmanned plane can complete flight under level Four wind-force, and without the concern for the high inside even from weather of wave, it is most important that energy
Substantially save the cost.
Detailed description of the invention
Fig. 1 is the schematic diagram of the measurement method of ship navigation lamp irradiating angle of the invention.
Specific embodiment
The present invention will be further described with reference to the accompanying drawings.
Referring to Fig. 1, the measurement method of ship navigation lamp irradiating angle of the invention, using the large size that can carry camera
Unmanned plane measures, and the flight operations of large-scale unmanned plane distance is 2 kilometers or more, and the follow-on mission time be half an hour with
On.Measurement method the following steps are included:
Step 1 opens the navigation lights of tested ship, closes the other boat lamps and harbour lamp of tested ship；
Step 2 installs camera and infrared lamp on unmanned plane, and guarantees the irradiating angle and infrared lamp of camera
Irradiating angle is identical, unmanned plane of then taking a flight test, and whether the light point of irradiation for observing infrared lamp is located at the center position of camera shooting
It sets；
Step 3, positioning unmanned plane are the coordinate of the navigation lights in the top of the navigation lights of tested ship；
Step 4 first operates at unmanned plane during flying to the set distance L away from navigation lights, and set distance L should be assisted with shipowner
Quotient is determining and at least 1 kilometer, and is consistent the height of unmanned plane and the height of navigation lights, then adjust the flight of unmanned plane
Angle, until the light of the infrared lamp on unmanned plane beats the edge in one side barn door of navigation lights, by the position of the unmanned plane
It installs as initial position, and records the coordinate of the initial position；
Step 5, according to irradiating angle as defined in navigation lights planning unmanned plane flight path, i.e., using navigation lights as the center of circle,
It is drawn and is justified as radius using set distance L, which is the flight path of unmanned plane；
Step 6, unmanned plane fly according to the flight path of planning, camera should be kept to begin during unmanned plane during flying
The light of navigation lights can be observed eventually, and the light of infrared lamp is radiated on navigation lights always, when camera can not observe
When the light of navigation lights or the light of infrared lamp are radiated at the another side barn door of navigation lights, stop unmanned plane, by unmanned plane
Stop position be set as final position, and record the coordinate of the final position；
Step 7, according to the seat of the final position of the coordinate and unmanned plane of the initial position of the coordinate of navigation lights, unmanned plane
Mark calculates the irradiating angle of navigation lights, that is, can determine whether the irradiating angle of the navigation lights meets regulation.
The measurement method of ship navigation lamp irradiating angle of the invention measures ship's navigation light irradiation using unmanned plane
Angle can both guarantee mechanical measurement and calculate instead of bring convenience and accuracy after gross visualization that large-scale unmanned plane could
To complete flight under level Four wind-force, and without the concern for the high inside even from weather of wave, it is most important that can substantially save into
This.Cost using barge deviation from voyage route measurement is ten tens of thousands of or more, and uses the cost of unmanned plane measurement very low.
Above embodiments are used for illustrative purposes only, rather than limitation of the present invention, the technology people in relation to technical field
Member, without departing from the spirit and scope of the present invention, can also make various transformation or modification, therefore all equivalent
Technical solution also should belong to scope of the invention, should be limited by each claim.
