Specific embodiment
Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, it should be understood that preferred reality described herein
Apply example only for the purpose of illustrating and explaining the present invention and is not intended to limit the present invention.
In the prior art, unmanned plane original-pack picture pick-up device mounted, user can be by manipulating remote control equipment, can be to nothing
It is man-machine to be shot control accordingly.In environment mapping operation, due to existing unmanned plane original-pack picture pick-up device mounted,
It is not dedicated picture pick-up device；Cause the efficiency in mapping operations extremely inefficient.
For this purpose, applicant improves unmanned plane, the original-pack picture pick-up device of dedicated picture pick-up device and unmanned plane is carried out
Replacement, to realize the efficient operation of unmanned plane mapping.But it has been found that since dedicated picture pick-up device is not adapted to unmanned plane,
User is that control shooting can not be carried out by the electric control system of unmanned plane and the remote control equipment of unmanned plane.
And existing solution: one is the assistance of unmanned plane manufacturer is sought, by adjusting dedicated picture pick-up device to be adapted to
The unmanned plane of unmanned plane manufacturer.But since the unmanned plane between different vendor is not general, the limitation of the program is high.It is another
It is to be equipped with independent remote controler to dedicated picture pick-up device, individually controls dedicated picture pick-up device operation.It is right respectively that the program needs
Unmanned plane, dedicated picture pick-up device are operated, and increase the operation difficulty of user, and to the hardware requirement of repacking picture pick-up device
Height, it is at high cost.
For this purpose, the present invention provides the devices that a kind of acquisition unmanned plane signal one controls capture apparatus.

Wherein, the indicator light that trigger signal is used to control on unmanned plane shows the execution state that unmanned plane is imaged.It needs
Be noted that existing unmanned plane, in order to allow user determine its operation control instruction whether be sent to unmanned plane,
And whether correctly executed by the load (such as picture pick-up device, spray appliance) on unmanned plane or unmanned plane, mainly pass through nobody
Several indicator lights on machine fuselage or be the indicator light on remote control equipment to be indicated.
As example, need to initialize when inorganic people opens, and the indicator light on fuselage can show and entirely initialize
The execution state of journey: the indicator light flashing red light in initialization, on fuselage；After completing initialization, the indicator light on fuselage is green
Lamp.As another example, original-pack picture pick-up device (load) on inorganic people, indicator light can show picture pick-up device to show entirely and take the photograph
As the execution state of process: when starting shooting, original-pack picture pick-up device needs adjust automatically acquisition parameters, and the indicator light on fuselage dodges
Bright green light；When completing shooting, closed after the indicator light is always on.And when shooting failure, the indicator light on remote control equipment or fuselage dodges
Bright red light.

Show the trigger signal of lamp.Further, trigger signal is converted to pulse signal by MUC module, and is controlled according to pulse signal
Reequip picture pick-up device.So that being retrofitted in the dedicated picture pick-up device on unmanned plane, the electrical control of unmanned plane script can still be by
System is controlled.The operation to dedicated picture pick-up device is not only simplified, operation ease is also improved, unmanned plane is also improved and exists
The efficient operation in the fields such as mapping.
Further, the present invention does not limit execution state indicated by the trigger signal: trigger signal can indicate
It is the state for starting shooting, it is the state shot when failing that trigger signal, which can also indicate that,.Preferably, trigger signal is to start to clap
The state taken the photograph: since unmanned plane original-pack equipment mounted is removed, unmanned machine testing, feedback shooting unsuccessfully require the time,
Especially when taking photo by plane automatically, it is easy to influence shooting effect.And trigger signal is to start the state of shooting, can be realized and makes an immediate response
