It is integrated with one piece of Arduino Leonardo on LattePanda, can connect the various kinds sensor module for supporting Arduino
Deng gray-scale sensor and ultrasonic sensor etc. such as can be used in this case.Machine vision (opencv) will be used simultaneously
Carry out road Identification.
After camera obtains image, image procossing is carried out by opencv.
After image procossing, coordinate system is established in processed image, while establishing at image X direction midpoint
One vertical line, referred to as reference line, as calibration.To manage image top midpoint behind place as standard, it is biased to a reference line left side, control electricity
Machine is turned right, and is biased to that reference line is right, and control motor is turned left, on line when keep straight trip.
Guarantee the accurate of robot movement by control motor steering, promise exists in the top of the image allowed after processing
On middle line, ensures that robot is walked on line, play the role of line walking.
Gray-scale sensor can carry out the connection of serial ports with Arduino, and the principle of gray-scale sensor utilizes different colours
Detection faces are to the degree of reflection of light, such as detection faces on black (depth) color asphalt road and white shunting traffic lines are to the anti-of light
Range degree is different, and the color of the two is different, and white light degree of reflection is larger, and the signal numerical value that gray-scale sensor is passed back is in certain model
It in enclosing, is advantageous in that and does not have to difference color, as long as the two has difference to the reflection of light, institute is in order to detection line road.
It is using
Setting gray-scale sensor a0 is standard value, its as shown in Figure 5 position, and when placement is located at white shunting traffic lines
Middle position, the value of reading is the reflected value (refer specifically to number had any different according to different road surfaces) of white shunting traffic lines, according to
The value fed back to is set, it is arranged as reference quantity, the value that remaining four gray-scale sensor is fed back to using a0 is standard value；No
Initial value must be set, and when use can be according to environment adjust automatically.
According to Fig. 5, tetra- gray-scale sensors of a1-a4 are distributed in front of device, and distance is between intermediate two sensors
15cm.According to country/professional standard, the width of white shunting traffic lines is 15cm on expressway.
The reading for being set in the gray-scale sensor a0 in running gear middle position is X, and other gray-scale sensor readings are done with X
Compare, is radiated in white shunting traffic lines more than or equal to X expression, is indicated with number 1；Indicate running gear in cypress less than X
On oil circuit face, indicated with number 0.Tetra- groups of sensors of a1-a4, totally 16 kinds of possible situations, exclude 8 kinds can not situations, (0,0,
0、1)、(0、1、0、1)、 (1、0、0、0)、(1、0、0、1)、(1、0、1、0)、(1、0、1、1)、(1、 1、0、1)、(1、1、1、1)。
Signal is passed back when gray-scale sensor keeps straight trip when being judged as (0,0,0,0)；
When passing signal back when gray-scale sensor and being judged as (0,1,1,0), running gear is as you were；Manually adjusted
Position of the full line walking apparatus on white lines makes gray-scale sensor pass signal (0,0,0,0) back
When gray-scale sensor passes signal back and is judged as (0,0,1,0), (0,0,1,1), (0,1,1,1) situation, running gear
It rotates by a certain angle counterclockwise；When it is (0,0,0,0) that gray-scale sensor, which passes signal back, stop operating, and keep straight on；
When passing signal back when gray-scale sensor and being judged as (0,1,0,0), (1,1,0,0), (1,1,1,0) situation, walking dress
It sets and rotates clockwise certain angle；When it is (0,0,0,0) that gray-scale sensor, which passes signal back, stop operating, and keep straight on.
In order to reach 150 meters of distance, after running gear placement, controlled by the way of constant speed plus timing.If
The initial velocity for setting the operation of running gear normal straight is V, device straight-line travelling (i.e. device is run under (0,0,0,0) state)
Time be T, remover adjustment when micro-displacement, can be calculated from the formula device linear running how long T
Stop later.
X=1/2aT2+VT
This situation can ignore acceleration a, simplification of a formula are as follows:
X=VT
According to the speed of setting, the time required for 150 meters of device linear running can be calculated.
HC-SR04 ultrasonic wave module is selected, SR04 is the sensor using Ultrasonic characteristics detecting distance.There are two its bands
Ultrasonic probe is used separately as emitting and receiving ultrasonic wave.Its measurement range is in 3cm-450cm.Number is used using Arduino
Word pin triggers SR04 module distance measurement function to the Trig pin at least high level signal of 10 μ s of SR04, returns if any signal,
Echo pin can export high level；For the ultrasonic sensor only with having detected whether that object passes through, output signal is high level table
When being shown with vehicle and passing through, remote prompting is performed the next step.
Select NRF24L01 as radio receiving transmitting module, the radio receiving transmitting module B of running gear, which is transmitted signals to, equally to be made
With the storage box of the radio receiving transmitting module of NRF24L01, the Ardunio in storage box receives signal, activates loudspeaker, reminds
Car owner's back car.It thereby realizes automatic places and reminds party's back car, and monitor back car at any time
Function.
Finally, it should be noted that the foregoing is only a preferred embodiment of the present invention, it is not intended to restrict the invention,
Although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art, still may be used
To modify the technical solutions described in the foregoing embodiments or equivalent replacement of some of the technical features,
All within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in of the invention
Within protection scope.
