Specific embodiment
In order to make the purpose of this utility model, technical solution and advantage are more clearly understood, and pass through tool below in conjunction with attached drawing
The utility model is further described in body embodiment.It should be appreciated that specific embodiment described herein is used only for solving
The utility model is released, is not used to limit the utility model.
Optical communication apparatus (also referred to as optical label) can transmit different information by issuing different light.Cursor
The example of label includes, but are not limited to the applicant on August 30th, the 2017 International Application Serial No. PCT/CN2017/099642 submitted
With optical communication apparatus disclosed in PCT/CN2017/099645.Optical label has farther away identification distance, is carried out by optical label
The method of unmanned plane guiding can be as shown in Figure 1, it includes the following steps:
Step 101: control unmanned plane advances near target optical label.
After the cargo that unmanned plane gets buyer to be sent to, the shipping address of buyer can be flown to first (that is, buying
The apartment of family) near.In one embodiment, which preferably can be the geographical location letter of target optical label itself
It ceases (for example, the accurate longitude and latitude of optical label, elevation information etc.), and can also include other information, such as the target cursor
The orientation information etc. of label.
Step 101 can be realized with possible existing ways various in this field.For example, unmanned plane can pass through GPS
The modes such as navigation fly to the shipping address nearby (namely near optical label of buyer).Existing GPS navigation mode can reach
Tens meters of accuracy rating.In a step 101, it closes the relative position that also can use between other optical labels and target optical label
Unmanned plane is directed near target optical label by system.Relative positional relationship between each optical label can be for example previously stored
And it can be obtained by unmanned plane.Unmanned plane can identify other optical labels along its flight path in flight, and be somebody's turn to do
Relative positional relationship between other optical labels and target optical label, then, unmanned plane can determine other optical labels of itself and this
Between relative positional relationship (such as by way of inverted orientation), it is thus possible to determine target optical label and unmanned plane
Between relative positional relationship.Based on the relative positional relationship, unmanned plane can be directed near target optical label.This field
Technical staff, which is appreciated that, is also possible to that unmanned plane is directed near target optical label using the combination of above-mentioned various modes.
Step 102: the information of some optical label transmitting of surrounding being carried out by the CMOS camera installed on unmanned plane
Acquisition, and identify transmitted information.
After near the optical label for having flown to buyer, unmanned plane can search its optical label within the vision, and pass through
The CMOS camera installed thereon is acquired the information of the optical label transmitting found and identifies transmitted information.Example
Such as, unmanned plane can obtain the continuous multiple image of some optical label by its CMOS camera, and be directed to each frame image
Judge that part corresponding with the position of light source is with the presence or absence of striped on the image or there are which type of stripeds, and determines
Information represented by each frame image.In one embodiment, if unmanned plane has found a cursor at it within sweep of the eye
Label, but its information transmitted can not be identified due to hypertelorism, then unmanned plane can be suitably close to the optical label, with reality
The identification for the information that now optical label is transmitted.
Step 103: judging whether the optical label is target optical label based on the information transmitted.
The information that unmanned plane can be transmitted based on optical label judges whether the optical label is target optical label.For example, nothing
It is man-machine whether to may determine that in transmitted information explicitly or implicitly comprising above-mentioned predetermined information.If comprising can be with
Determine that the optical label is target optical label, otherwise, can determine the optical label not is target optical label.In one embodiment,
Can judge whether the optical label is target optical label by unmanned plane itself.In another embodiment, unmanned plane can incite somebody to action
The information that optical label is transmitted is transmitted to the server that can be communicated with unmanned plane, by the server based on the letter transmitted
Breath judges whether the optical label is target optical label, and judging result is sent to unmanned plane.The information of optical label transmitting can be with
It is encrypted information.
Step 104: if the optical label is target optical label, controlling unmanned plane and advance to the optical label.
Since unmanned plane has determined that some optical label in field range is air objective, unmanned plane can
For example free from errors to be flown to the optical label by the vision guide of the optical label.In one embodiment, unmanned plane can
To use existing ranging technology to stop at some distance of optical label, such as apart from tens centimetres of optical label of position
It sets, avoids collision optical label.In one embodiment, unmanned plane can be based on the vision of the image for the optical label that it takes
Distortion is to be reverse-located and be adjusted its flight line, so that unmanned plane can finally be stopped at relative to a certain of optical label
On direction, for example, the front of optical label.The shelf for receiving, unmanned plane can be disposed in the front of the optical label
Easily cargo can be delivered in the shelf.
Rack is thrown in the unmanned plane express delivery delivered for unmanned plane that lower mask body introduces the utility model, to solve automatic receive
The problem of goods.
