Description
Technical field
The present invention is a kind of wheeled carriage device suitable for field crops, can be with the digitlization of automatic collection field crops
Image.The device is by liftable wheel undercarriage, removable darkroom, GPS navigation system, trolley control system, crop Image Acquisition
7 functional module compositions such as system, solar electric power supply system, computer, are made using liftable wheel undercarriage and RGB camera acquisition
The image of object different times saves the crop image of acquisition using computer, and the shadow of background interference is eliminated using removable darkroom
It rings, using GPS navigation system pilot trolley along crops row automatically walk, provides electric energy using solar panel for trolley,.
Background technique
As the improvement of people's living standards, requiring the quality safety of agricultural product higher and higher, agricultural product retrospect system
Establish too impatient to wait, and field information acquisition is the committed step that agricultural product are traced to the source.Currently, agricultural products in China field information is adopted
Collection relies primarily on manually to complete, time-consuming and laborious, while accuracy and real-time be not strong.As the day of communication technology and network is new
The moon is different, and agricultural production has welcome new opportunity.For this purpose, the present invention constructs a kind of wheeled carriage field image automatic collection system
System, it can be in field according to the walking of setting path and the convenient and efficient growth image for acquiring crops with no damage without intervention.
Summary of the invention
The present invention, which provides one kind, can be used for the acquisition of field crops image, can overcome complicated landform, outdoor illumination effect,
It can accomplish darkroom photo environment, Image Acquisition can be carried out to the crop of different height, can be reduced damage and the energy original place to crop
The imaging device of turning, the device is by liftable wheel undercarriage, removable darkroom, GPS navigation system, trolley control system, work
7 functional module compositions such as object image acquisition system, solar electric power supply system, computer,
1) liftable wheel undercarriage: since field topography is extremely complex, often there is uneven situation on ground, it is contemplated that this
A little problems, the device are equipped with large diameter wheel, and load onto damping spring and steering shaft, make trolley can be with pivot turn and can
It is travelled with stable in field.The top of wheel designs four liftable axis and is used for connecting base plate, makes chassis far from the height on ground
Degree is realized controllable.One direct current generator is installed respectively on four wheels, each power of motor is 100W, and total capability for load exists
120-150Kg, two wheels of left and right are at a distance of 1.5m.Solar panel is installed, so that solar panel receives more above chassis
More solar irradiations generates more electric energy.Installation digital camera is used to acquire picture below chassis.
2) darkroom is moved: since field crops growing state is complicated, often by ambient light when acquiring crop picture
According to the influence with the crop other than target crop, so the removable darkroom that the present invention designs is carried by trolley, when trolley is walked
When to the surface of target crop, the control of control system sky is landed automatically by the darkroom that three face background cloths form, thus play every
Effect from illumination and other crops.
3) GPS system: the effect of the system is that trolley has been set in advance in the good path to be walked of trolley of filed planning in advance
It will stop among to each cell, clap photograph to camera and readvanced.A signal receiver is set up in field, receiver connects
The control system of trolley is passed to after the signal sent by satellite, control system completes next work.The precision of the GPS is reachable
0.1m, the work of entirely appropriate field trolley.
4) trolley control system: the effect of the system is by judging the received letter from satellite of field signal receiver
Number determine the position of trolley, then the signal according to the actual situation by advance, retrogressing and stopping is transmitted to PLC, to control trolley
Advance, retrogressing and stopping, the lifting that camera is taken pictures with darkroom can also be controlled.
5) image capturing system: when trolley is in crop automatically walk in the ranks, trolley often proceeds to a fixed cell
It will stop, the image of phase chance automatic collection crop.Compared with regular industrial camera, digital camera is not only cheap, and
And the higher image of resolution ratio can be obtained.
6) solar electric power supply system: trolley whole system operates normally the voltage for needing 12V, and general 32mA battery is only
Energy normal power supply 4h, it is necessary to charge.Therefore, the solar panel that installation power is 100W on trolley, sunny
In the case of, it can generate electricity within one day 0.6 degree, trolley can be supplied and work normally 4h.Use solar panel, it can save electricity
It can save the charging time again, it is environment friendly and pollution-free.
7) computer: computer can automatically save the crop image of trolley acquisition, convenient to check and use in the future.
In conclusion field of the present invention is taken pictures, the technical point of trolley includes:
1) liftable chassis
The design has accomplished chassis liftable, to meet requirement of the crop of different height to Image Acquisition when, accomplishes
Optimal acquisition to Crop Information is especially suitable for acquisition germination period and the bigger crop image of maturity period height gap.
2) the mobile darkroom in field
The design has accomplished to carry a darkroom by trolley, when trolley goes to some fixed cells top, control system meeting
Signal is received, falls the darkroom being made of three black background cloth automatically, camera shoots side view photo from one end of no background cloth.
The effect for wherein moving darkroom is to eliminate natural lighting to influence to shooting crop image bring, and Target cell and side is small
The crop in area keeps apart, and non-targeted cell is eliminated when taking pictures, and to Target cell, the bring in image acquisition process influences.
3) turning space is saved
The design uses four-wheel drive, by above each wheel plus a steering shaft, accomplished can pivot turn, make
Trolley achieves that turning function in minimum space, compared with traditional turning mode, turning space is greatly saved, is convenient for
Work of the trolley in field.
4) solar recharging
Solar panel is one kind using photoelectricity transformation principle by solar radiation light by semiconductor transition for electric energy
Device, it is only necessary to the place that outdoor has sunlight to shine directly into can be used, solar panel is easily installed, be easy to expansion,
It is readily disassembled, also very economical material benefit.By installing solar panel on trolley, solves the daily powerup issue of trolley.
5) it spends less, is high-efficient
At 10000 yuan or so, notebook, digital camera can also reuse cost of the present invention.It is small after starting trolley
Vehicle starts along crop row the top view and side view of a crop to be acquired every 8S, so one with 0.4m/s speed automatically walk
A hour can acquire 400 images.Relatively with traditional measurement method, Image Acquisition efficiency is greatly improved, meets one
Its domestic demand acquires the experiment demand of thousands of plants of crop images.
