Continue the step 507 in Fig. 5 A illustrated embodiment after examination to step 509, details are not described herein.
In conclusion the acquisition methods of crossing traffic information provided by the embodiments of the present application, in crossing traffic information set
Where the middle vehicle for recording the crossing for having vehicle front that will pass through when the crossing location information in lane, directly from the crossing traffic
The crossing traffic information in lane, flexibility are higher where obtaining vehicle in information aggregate.
Scene is established for crossing traffic information set, corresponding acquisition vehicle can be separately configured and execute crossing traffic
The establishment process of information aggregate can also execute the establishment process of the crossing traffic information set by common vehicle, please join
Fig. 5 A is examined, the process that the application establishes crossing traffic information set specifically can be as shown in Figure 5A, which may include:
Step 501, vehicle obtain the classification information and face of the signal lamp at the first crossing after detecting ground oriented identification
Color characteristic.
Vehicle can persistently identify ground oriented identification when driving towards crossing by ground oriented identification identification technology, and
After detecting ground oriented identification, the classification information and color of the signal lamp at the first crossing are obtained by signal lamp identification technology
Feature.Ground oriented identification is generally arranged on the position apart from crossing certain distance and the road surface between stop line, and vehicle exists
When detecting ground oriented identification, it is believed that soon drive into crossing, the signal lamp for obtaining the first crossing can be started at this time
Classification information and color characteristic.
Wherein, the classification information of signal lamp is used to indicate the classification of signal lamp, and the classification of signal lamp may include round letter
Signal lamp, straight trip arrow signal lamp, left-hand rotation arrow signal lamp, right-hand rotation arrow signal lamp, straight and turning left arrow signal lamp, straight trip and
Right-hand rotation arrow signal lamp and u-turn arrow signal lamp etc., information indicated by these signal lamps can refer to the relevant technologies and method
Rule, details are not described herein.
Optionally, since the ground oriented identification at crossing is less, and vehicle may not be able to identify that each ground is led
To mark, thus vehicle can start the classification for obtaining the signal lamp at the first crossing when detecting ground oriented identification for the first time
Information and color characteristic give subsequent step reserved abundance with the acquisition moment of the classification information of advance signal lamp and color characteristic
Time.
The color characteristic of signal lamp can be the one or more features for judging the color of signal lamp.Due to crossing
Environment is complex, the frame image (the frame image that the image acquisition components 22 as shown in through Fig. 2A obtain) that vehicle obtains
It is difficult to directly and accurately judge the color of signal lamp, thus can persistently obtain signal lamp after detecting ground oriented identification
Color characteristic, to obtain the multiple image in a continuous time period, the color that signal lamp is obtained by the multiple image is special
Sign, can be improved the accuracy of the color characteristic of acquisition in this way.The color characteristic can be for based on coloration, color saturation and brightness
The color characteristic of (Hue Saturation Value, HSV).Optionally, in actual implementation, hsv color feature can be removed
In brightness, to drop the influence of low ambient light, and using coloration and color saturation as color characteristic.
Optionally, in step 501, vehicle can be by obtaining ground image, and with ground oriented identification identification technology
The ground image is analyzed, it (can be with when there are ground oriented identification with the presence or absence of ground oriented identification in ground image to identify
Identify the classification of ground oriented identification), as shown in Figure 2 A, the process can control assembly 21 in the car control image and obtain
Component 22 is completed.
Optionally, in step 501, the available signal lamp image of vehicle, and image is identified with signal lamp identification technology
In signal lamp classification information and color characteristic, as shown in Figure 2 A, the process can control assembly 21 in the car control
Image acquisition components 22 are completed.
In practical realization, which may include the first Image Acquisition structure and the second Image Acquisition knot
Structure, the first Image Acquisition structure are installed near vehicle mirrors, using wide-angle camera (such as 90 degree of wide-angle cameras), installation
When partial below certain angle (such as 3-4 degree), for acquiring ground image, it is attached that the second Image Acquisition structure is installed on vehicle mirrors
Closely, using general angle camera (such as 60 degree of cameras), when installation, is horizontally mounted, for acquiring the first image of signal lamp image
Acquire the camera that the camera in structure and the second Image Acquisition structure can be adjustable angle, such as cradle head camera.
Step 502, vehicle are determined when detecting the stop line at the first crossing according to the position of the stop line at the first crossing
The position of signal lamp.
Vehicle can continue the detection for carrying out stop line after detecting ground oriented identification information, and detect
When the stop line at the first crossing, according to the position of the location determination signal lamp of the stop line at the first crossing.
Since signal lamp and stopping line position are relatively fixed, and the height of signal lamp can be pre- according to corresponding national standard
If therefore, in practical applications can according to the inside and outside parameter of camera calibration, vehicle near stop line when signal lamp scheming
Location information as according to the preset signal lamp elevation information of national standard estimates signal lamp relative to vehicle in stop line
The position 3D when nearby.The information can be used to derive the position of signal lamp in the picture when vehicle does not reach near stop line
Information.
For example, obtaining crossing when vehicle driving is at crossing by crossing location information and the lane information of identification and handing over
Logical information aggregate.The location information that stop line is obtained in crossing traffic information set estimates vehicle in conjunction with current vehicle position
Relative position away from stop line.Relative position of the vehicle of comprehensive estimate away from stop line is obtained from crossing traffic information set
Signal lamp relative to vehicle near stop line when position and camera inside and outside parameter, estimation signal lamp it is current in vehicle
The position of position moment in the picture, so that the identification for signal lamp provides effective prior information.
The position of above-mentioned signal lamp is the position in preset coordinate system, which can be world coordinate system,
It can be the image coordinate system in the second Image Acquisition structure of acquisition signal lamp image, common, which is image coordinate
Position in system, effectively to be tracked signal lamp in the picture based on the position.
Wherein it is determined that the mode of the distance between stop line and signal lamp may include it is a variety of, be provided with survey in the car
When away from sensor, the distance between stop line and signal lamp directly can be measured by the distance measuring sensor, vehicle can be with root
The distance between stop line and signal lamp are determined according to the multiframe that image acquisition components obtain includes the image of signal lamp, such as are adopted
The distance is determined with technique of binocular stereoscopic vision, details are not described herein.
The color characteristic of step 503, vehicle based on acquisition, establishes color characteristic distributed model.
After vehicle detection to stop line, vehicle can stop the acquisition of color characteristic, and according to detecting that ground leads
Color characteristic distributed model is established to mark to the color characteristic detected in stop line this period, and according to the color characteristic
Distributed model determines the color of vehicle signal lamp when detecting stop line.Pass through multiframe acquired in a continuous time period
The color characteristic distributed model that image is established can accurately reflect the color characteristic of signal lamp, improve the identification in subsequent process
Probability.
The color characteristic distributed model can be the color characteristic distributed model based on Gaussian Profile, for example, hsv color
Model, the model are also referred to as hexagonal pyramid model (Hexcone Model).
Although also having in the related technology similar the side of signal lamp color is determined by establishing color characteristic distributed model
Method, but the color characteristic distributed model in method in the related technology is the face of the signal lamp based on some crossings as sample
What color characteristic was established, do not have specific aim for the signal lamp at some crossing, also without real-time, but the letter at each crossing
The diversity ratio of ambient conditions locating for signal lamp (such as height, direction, abrasion and pollution of signal lamp etc.) is larger, thus related skill
That establishes in art does not have the accuracy meeting that targetedly color characteristic distributed model identifies the color of some signal lamp
It is lower.The color characteristic distributed model that the embodiment of the present application is established corresponds to the mould of the signal lamp at uniquely determine crossing
Type has very strong specific aim, can accurately react the color characteristic of the signal lamp at the crossing uniquely determined, in turn
Judge that the accuracy of the color of signal lamp also can be higher according to the model.
In actual implementation, for the same crossing can establish the color characteristic distributed model corresponding to red eye with
And the color characteristic distributed model corresponding to greensignal light is (since red eye and amber lamp indicate that vehicle stops
Only, thus usually amber lamp can be classified as red eye when carrying out signal lamp identification).For same crossing, this
Two color characteristic distributed models can be passes through crossing institute's acquired image foundation based on same vehicle at least once
(for example, a vehicle successively acquires the image that signal lamp takes on a red color in the period for once passing through the crossing and signal lamp is in
The image of green, based on this period, the image of acquisition can establish two color characteristic distributed models), it is also possible to based on not
Pass through what the crossing institute acquired image was established at least once with vehicle, the application does not limit this.
Optionally, as shown in Figure 2 A, color characteristic distributed model can be established by the control assembly 21 in vehicle.
Step 504, vehicle determine that signal information, signal information include position, classification information and the color of signal lamp
Feature distribution model.
In position, classification information and the color characteristic distributed model for obtaining signal lamp by step 501 to step 503
Afterwards, these information can be determined as signal information by vehicle.
Since what the image including signal lamp that image acquisition components obtain was illuminated by the light is affected, and illumination is for signal
The influence of lamp color is usually periodically variable at any time, and corresponding color characteristic distributed model also will receive influence, thus
Color characteristic distributed model and time can be got up at this correlate, to reduce the illumination of different periods for signal lamp face
The influence of the judgement of color.
Optionally, signal information further includes the corresponding object time section of color characteristic distributed model, the object time
Section is the section in preset n time interval where the acquisition period of color characteristic, n time interval for will be preset when
Between the period divide obtain at equal intervals, n is the integer greater than 1.I.e. vehicle passes through the first crossing in this n time interval respectively
When, every time by the step of being performed both by above-mentioned steps 501 to step 504, the first crossing can be obtained in preset week time
Interim color characteristic distributed model, further, when each time interval in this n time interval is at least respectively for vehicle
Once pass through the first crossing, is the image of red light and green light respectively to acquire signal lamp in same time interval, then passes through repetition
Whole color characteristic distributed modes of first crossing in the preset time cycle can be obtained by executing step 501 to step 504
Type.
Optionally, since the light conditions of the different periods in every day tend to periodically change, thus it is preset when
Between the period can be 1 day.When the preset time cycle is 1 day, n can be that 8 or other numerical value, the present embodiment do not make rising limit
System.It then, can be as shown in table 1 for the signal information at a crossing comprising: position, classification information and the face of signal lamp
Color characteristic distributed model and corresponding object time section, record has the face of red eye in each object time section
The color characteristic distributed model of color characteristic distributed model and greensignal light is assumed in table 1 to divide as unit of 1 day time
8 object time sections, and assume that corresponding color characteristic distributed model is complete in each object time section, but practical
There may be color characteristic distributed model in partial target time interval not set up also in.

As shown in Figure 5 B, a kind of acquisition process of crossing location information may include:
Sub-step 5051, when detecting ground oriented identification, vehicle obtain current location, which is properly termed as first
The initial position in lane.
Optionally, due to may detect that multiple ground oriented identifications before vehicle reaches stop line, in order to avoid repeating
The initial position for recording first lane, can be set the flag bit of a ground oriented identification in vehicle, the flag bit just
Initial value is second value, and vehicle can set the flag bit of ground oriented identification to before detecting ground oriented identification
Two-value, and after detecting ground oriented identification, the first value is set by the flag bit of ground oriented identification, vehicle is being examined every time
When measuring ground oriented identification, whether the flag bit that can detecte ground oriented identification is the first value, the oriented identification on ground
It, can be without the record of position when flag bit is the first value;When on ground, the flag bit setting of oriented identification is not the first value,
The position of available vehicle, and the first value is set by the flag bit of ground oriented identification.Wherein, the first value and second value are
Identify the unequal value of any two of the flag bit of ground oriented identification.For example, the first value is 0, second value 1.
Optionally, vehicle can obtain current location, and by the current location when detecting ground oriented identification for the first time
As the initial position of first lane, to improve the success rate of identification.
In addition, the flag bit of ground oriented identification can be again set at second after through the first crossing by vehicle
Value.
Sub-step 5052, when vehicle detection is to stop line, obtain the position of vehicle, which is the stopping of first lane
Line position.
It, can be in the multiple of the intersection in any two road by the initial position and stopping line position of first lane
The first crossing is uniquely determined in crossing.Thus the initial position and stopping line position can be used as the crossing position letter at the first crossing
Breath.
In addition, crossing location information can also include the position of stop line and the direction at the first crossing, pass through the two
Information also can uniquely determine the first crossing in multiple crossings of the intersection in any two road.
In embodiments herein, Fig. 2A is please referred to, vehicle can obtain the position where vehicle by positioning component 27
It sets.In the embodiment of the present application, the information of position typically GPS coordinate.
The lane information in each lane may include the carriageway type in each lane and the lane serial number in each lane, often
The lane serial number in a lane can be the serial number for one lane of unique identification in multiple lanes at a crossing.Such as Fig. 5 C

The curb or yellow lane line of side then the lane at the first crossing are numbered since first lane of the rightmost side, successively
Setting R1, R2, R3 for lane serial number ..., Rx, x are the lane sum at the first crossing.If first identifying on the left of vehicle heading
Curb or yellow lane line, then the lane at the first crossing is numbered successively since first lane of the rightmost side by vehicle
Road serial number is set as H1, H2, H3 ... Hx.
Further, since some Lane detection technologies can only identify a certain lane when vehicle is located at a certain lane
The lane line in two sides lane, thus when using these Lane detection technologies, all lanes can be identified by lane change
Lane line.
The lane serial number of first lane where sub-step 5054, vehicle determine.
Sub-step 5055, vehicle obtain the carriageway type of first lane based on ground oriented identification recognition result.
Vehicle may detect that multiple ground oriented identifications in the process of moving, since road conditions may complex, vehicle
May be different for the recognition result of same type of ground oriented identification, vehicle can choose one of ground guide mark
Know carriageway type of the recognition result as first lane.The selection course can be optional process, be also possible to be based on
Pre-set screening rule carries out the process of selection, such as by the result of the most identification of frequency of occurrence in multiple recognition result
Carriageway type as first lane.
It, can be by the lane serial number and vehicle of first lane after the lane serial number and carriageway type that first lane has been determined
Road type association is got up.
Terminate to step 505, vehicle has obtained the corresponding signal of information and the lane in the lane where vehicle
The crossing traffic informations such as the color characteristic distributed model of lamp.
Crossing location information based on the first crossing of step 506, vehicle, the lane information of first lane and acquisition
The crossing traffic information in one lane establishes one group of corresponding relationship.
Optionally, this group of corresponding relationship can be established by the control assembly in vehicle.Further, since vehicle is not by
With crossing when, the curb identified first may be the curb on the left of vehicle heading, it is also possible to vehicle heading
The curb on right side, thus when establishing corresponding relationship, it can be by lane serial number according to the direction where the curb recognized first
Unification (such as be unified for and sort since the lane of the leftmost side, or be unified for and sort since the lane of the rightmost side) is carried out, to keep away
The lane information exempted from corresponding relationship is chaotic.
Step 507, vehicle judge whether to violate the traffic regulations according to driving information;The execution when vehicle violates the traffic regulations
Step 508;When vehicle does not violate the traffic regulations, step 509 is executed.
The corresponding relationship and driving information that vehicle can be established according to step 506 to determine whether violate the traffic regulations,
The traffic rules can refer to relevant laws and regulations of the first crossing location about road traffic.Illustratively, table 2 shows symbol
Close traffic rules various driving informations, if the running information record of vehicle in table 2, it may be considered that vehicle does not violate traffic
Rule, if the driving information of vehicle is not recorded in table 2, it may be considered that vehicle violates traffic rules.

In table 1, the first row indicates the classification of each column data, and one group of corresponding information of each behavior vehicle is exemplary,
Information represented by 1 second row of table are as follows: for vehicle driving in Through Lane, signal lamp is straight trip arrow signal lamp or circular signal
Lamp, the color of signal lamp be it is red, the speed of vehicle is 0, and the driving information of this vehicle does not violate the traffic regulations.Traveling in table 1
Information can be obtained from vehicle control device, and the color of carriageway type, signal lamp type and signal lamp can be established by step 506
Corresponding relationship in obtain.The case where onrelevant signal lamp in table 2 may include two kinds, arrive signal lamp one is unidentified,
Another kind is that crossing is not provided with signal lamp, and in both cases, the speed of vehicle is greater than 0 it is considered that meeting traffic rule
Then.
Step 508, vehicle delete this group of corresponding relationship.
The case where vehicle violates the traffic regulations really is excluded, if vehicle identification goes out current driving information and violates traffic rule
Then, then show that, there may be the information of mistake in the corresponding relationship of step 506 foundation, which may not have reference price
Value, thus the corresponding relationship can be deleted.
This group of corresponding relationship is added in crossing traffic information set by step 509, vehicle.
When vehicle does not violate the traffic regulations, this group of corresponding relationship can be added to crossing traffic information set by vehicle
In.The crossing traffic information set can be located in the memory of vehicle local, can also be located in server.
In the acquisition methods of crossing traffic information provided by the embodiments of the present application, according to crossing location information, lane information
And the crossing traffic information of acquisition establishes corresponding relationship, vehicle can be using the corresponding relationship as acquisition crossing traffic information
Prior information, to improve the robustness of the acquisition methods of crossing traffic information.Exemplary, some identification technologies can in the related technology
The factors such as distance, surface gathered water, road surface oriented identification are worn, front vehicles are blocked can be limited to, to be difficult to obtain lane class
Type, but method provided by the embodiments of the present application can obtain carriageway type by the other information in corresponding relationship.
In addition, being based on corresponding relationship provided by the embodiments of the present application, it may be limited to distance in the related technology and be difficult to know
Not Chu signal lamp color, but the face of signal lamp can be determined that in larger distance according to the information recorded in corresponding relationship
Color.
In conclusion the acquisition methods of crossing traffic information provided by the embodiments of the present application, are handed over by pre-establishing crossing
Logical information aggregate, in order to which the crossing location information after vehicle at the crossing of process is recorded in the crossing traffic information set
When, the crossing traffic information in lane where vehicle can be obtained directly from the crossing traffic information set, so that crossing traffic
The acquisition speed of information is very fast, and flexibility is higher.
Step 501 to step 509 is the process that a certain vehicle in the application establishes traffic information set, and crossing is handed over
Logical information aggregate establishes scene, and the process for establishing traffic information set can also be established by server and vehicle cooperation, this
When, the application provides a kind of traffic system, which includes server and multiple vehicles, and structure can refer to above-mentioned figure
2B, as shown in fig. 6, the process may include following several steps:
Step 601, server obtain the initial crossing traffic information set that multiple vehicles are established.
In practical application, each available initial crossing traffic information set of vehicle, and it is sent to server, by servicing
Device is integrated accordingly, each vehicle obtain initial crossing traffic information set process can with reference to above-mentioned steps 501 to
Step 510.
Step 602, server, will be multiple according to the crossing location information recorded in multiple initial crossing traffic information set
Initial crossing traffic information set is divided into multiple alternative crossing traffic information set, each alternative road according to the difference at crossing
The corresponding crossing of mouth traffic information set.
In initial crossing traffic information set acquired in multiple vehicles, it may include the multiple groups pair corresponding to identical crossing
It should be related to, server can be using the corresponding multiple groups corresponding relationship in each crossing as an alternative crossing traffic information set.
Step 603, server merge at least one set of corresponding relationship in each alternative crossing traffic information set.
For each alternative crossing traffic information set, the mode of the merging may include in following two mode at least
A kind of mode:
The first, for the merging mode of lane information: using ballot decision mechanism, server retains at least one set of corresponding
The lane information of highest scoring in relationship.I.e. for certain lane information at the crossing of any one, alternative crossing can be handed over
The most lane information of frequency of occurrence remains in logical information aggregate, and the lane information of other same types is deleted, exemplary
, in the alternative crossing traffic information set at the first crossing, record for the type in lane has in 5 corresponding relationships and remembers
Carrying the first crossing includes a Through Lane and a right-turn lane, and having 3 corresponding relationships to record the first crossing includes a left side
It changes trains or buses and a right-turn lane, there is that record the first crossing in 1 corresponding relationship include 1 Through Lane, then the first crossing
Highest scoring including a Through Lane and right-turn lane this carriageway type information can retain carriageway type letter
Breath, and delete other carriageway type information.
In addition, by Fig. 5 A illustrated embodiment it is found that since vehicle is when by different crossings, the curb that identifies first
It may be the curb on the left of vehicle heading, it is also possible to the curb on the right side of vehicle heading, thus different vehicle obtains
Lane information in lane serial number may disunity, thus server can be by lane serial number according to the curb recognized first
The direction at place carries out unification and (such as is unified for and sorts since the lane of the leftmost side, or be unified for since the lane of the rightmost side
Sequence), it is chaotic to avoid the lane information in corresponding relationship.
Second, for the merging mode of signal information: using the ballot decision mechanism based on weight, server retains
The weight of each signal information of the signal information of highest scoring and, ginseng negatively correlated with reference to duration at least one set of corresponding relationship
When examining in a length of signal information color characteristic acquisition period and current time duration gap.I.e. the acquisition of color characteristic when
Section is bigger with the duration gap at current time, then the weight of color characteristic is smaller, this is because color characteristic may be with the time
Variation and generate variation (such as illumination can change with the variation in season, and then impact to color characteristic), thus distance
The accuracy of current time closer signal information is higher, and then when merging signal information, can will apart from it is current when
Carve the higher of the weight setting of closer signal information.
Server can delete the signal information apart from current time certain time length (such as half a year), and it is current only to adjust the distance
Signal information of the moment in the certain time length merges, to further increase the accuracy of signal information.
Alternative crossing traffic information collection after all merging is combined into crossing traffic information set by step 604, server.
Server hands over the initial crossing that multiple vehicles upload after incorporating all alternative crossing traffic informations
, there are the corresponding lane information of only one and crossing traffic information, server in each crossing recorded in logical information aggregate
The alternative crossing traffic information collection after all merging can be combined into crossing traffic information set at this time.
Step 605, server each vehicle into multiple vehicles provide mouth traffic information set.
Server can provide traffic information set to vehicle by wireless network.
The embodiment of the present application merges the initial crossing traffic information set that multiple vehicles are established by server, with one kind
The mode of crowdsourcing has reached the crossing traffic information that can quickly generate that one includes the crossing traffic information at multiple crossings
Set performance.
In conclusion the acquisition methods of crossing traffic information provided by the embodiments of the present application, server can be by multiple vehicles
Establish initial crossing traffic information set merge into crossing traffic information set, the set is by including multiple vehicle institutes
The corresponding relationship of foundation, thus the crossing traffic information covered is more, can facilitate the use when driving towards crossing of each vehicle,
Improve the availability of crossing traffic information set.
For the usage scenario of crossing traffic information set, as shown in Figure 7 A, which may be considered reality shown in Fig. 4
After the step 404 for applying example, vehicle obtains the process after the corresponding crossing traffic information of first lane.Road provided by the present application
The acquisition methods of mouth traffic information can also include following several steps:
Step 701, between the stop line at vehicle with the first crossing at a distance from be less than or equal to third distance threshold when, vehicle
Carry out stop line information acquisition.
It, can be according to crossing traffic information pair after the corresponding crossing traffic information of first lane of the vehicle where obtaining
The position of the stop line recorded in the crossing location information answered determines that (first crossing is the first crossing position for vehicle and the first crossing
The corresponding crossing of confidence breath) the distance between stop line whether be less than or equal to third distance threshold, and with the first via
The distance between mouth (shows that vehicle may soon reach stop line) when being less than or equal to third distance threshold at this time, is stopped
The acquisition of line information.Third distance threshold, which can be equal to, to be detected between the position of road surface oriented identification and the position of stop line
Distance, i.e. vehicle can begin to carry out after detecting road surface oriented identification the acquisition of stop line information.
Vehicle can obtain crossing traffic information set by method shown in Fig. 5 A, or obtain crossing from server and hand over
Logical information aggregate.
Step 702, when not collecting stop line in preset duration, vehicle obtains current vehicle speed.
When not collecting stop line in preset duration, show that vehicle may be since some interference be (such as front vehicles
Block or rain and snow weather cause the stop line on road surface to be blocked) fail accurate detection to stop line, it is available at this time
Current speed.
Step 703, vehicle determine the signal lamp state at the first crossing.
As shown in Figure 7 B, this step may include following 4 sub-steps:
Sub-step 7031, vehicle acquisition include the image to be analyzed of signal lamp.
Vehicle can obtain the image to be analyzed comprising signal lamp by image acquisition components.
The position of sub-step 7032, vehicle based on the signal lamp recorded in current location and crossing traffic information, determine to
Analyze the position of signal lamp in image.
Vehicle can establish a coordinate system (such as world coordinate system), and in the coordinate system based on current vehicle position,
The position of the signal lamp recorded in the height and crossing traffic information of image acquisition components, determines signal lamp in image to be analyzed
Position.The coordinate system can be corresponding to the setting height with image acquisition components.
Color characteristic at the position of sub-step 7033, vehicle based on signal lamp in image to be analyzed, establishes face to be processed
Color characteristic distributed model.
After position of the signal lamp in image to be analyzed has been determined, the color characteristic of the position can be extracted, establish to
Color characteristic distributed model is handled, establishing for the model can be no longer superfluous herein with reference to the step 503 in Fig. 5 A illustrated embodiment
It states.
The color characteristic that sub-step 7034, vehicle will record in color characteristic distributed model to be processed and crossing traffic information
Distributed model is compared, to determine the color of current signal light.
The color characteristic distributed model recorded in crossing traffic information may include the color spy corresponding to red eye
Distributed model and the color characteristic distributed model corresponding to greensignal light are levied, it can be by color characteristic distributed model to be processed
It is compared with the two models, using the color of the high corresponding signal lamp of color characteristic distributed model of similarity as current letter
The color of signal lamp.The state of signal lamp can be determined according to the color of signal lamp, it is exemplary, if the color of signal lamp is green,
Then the state of signal lamp is prevailing state, if the color of signal lamp is red, the state of signal lamp is forbidden state.
Step 704, when vehicle current vehicle speed be greater than preset vehicle speed threshold value, and the signal lamp state at the first crossing be it is forbidden
State, vehicle continuous updating current location, until the stop line that the current location of vehicle and crossing traffic information set are recorded
When the distance of position is less than first distance threshold value, stop line detection notice is issued.
When vehicle current vehicle speed be greater than preset vehicle speed threshold value, and the signal lamp state at the first crossing be forbidden state, and
It, can when being less than first distance threshold value at a distance from the stopping line position that the current location of vehicle is recorded with crossing traffic information set
There is the possibility for rushing across stop line to think vehicle at any time, in order to avoid the generation of this case, stop line can be issued at this time
Detection notice, the notice is for having confirmly detected stop line.The first distance threshold value is less than third distance threshold, exemplary
, which can be determined by the maximum distance that stop line identification technology can identify.
Step 705, when the current vehicle speed of vehicle be 0 or first the signal lamp state at crossing be prevailing state, and vehicle
With when stopping being less than second distance threshold value at a distance from line position, vehicle issues stop line detection notice for current location.
When speed be 0 and vehicle current location in corresponding relationship stop line position at a distance from be less than second distance threshold value
When, show that vehicle may have been travelled to stop line, then vehicle can issue stop line detection notice, alternatively, when first
The signal lamp state at crossing is prevailing state, and the current location of vehicle is less than second distance threshold value at a distance from stopping line position
When, vehicle may also have been travelled to stop line, then vehicle can also issue stop line detection notice.Wherein, second away from
It is less than first distance threshold value from threshold value, illustratively, second distance threshold value can be 5 meters.
In actual implementation, the signal lamp of time interval where current time may not recorded due to crossing traffic information set
Color characteristic distributed model, alternatively, record has and the signal lamp of time interval where current time in crossing traffic information
The different color characteristic distributed model of the corresponding color of color characteristic distributed model more easily uses crossing traffic in order to subsequent
Information aggregate, at this point, vehicle also supplements Unrecorded crossing traffic information in crossing traffic information set, the process
The process for updating crossing traffic information set can be considered as, detailed process can be with reference to subsequent step 405 to step 407.
As seen in figure 7 c, the process of the update crossing traffic information set may include following several steps:
Step 706, in the stop line of traveling to the first crossing, whether recorded in vehicle detection crossing traffic information and worked as
The color characteristic distributed model of the signal lamp of time interval where the preceding moment.
This step is the case where vehicle collects stop line in preset duration, and vehicle can detecte crossing traffic letter at this time
The color characteristic distributed model of the signal lamp of time interval where whether recording current time in breath.
If the color characteristic of the signal lamp of time interval where current time is not recorded in step 707, crossing traffic information
Distributed model, alternatively, there is and the color characteristic of the signal lamp of time interval where current time point record in crossing traffic information
The different color characteristic distributed model of the corresponding color of cloth model, the color that vehicle obtains the signal lamp at current first crossing are special
Sign.
The acquisition modes of the color characteristic can be no longer superfluous herein with reference to the step 501 in above-mentioned Fig. 5 A illustrated embodiment
It states.
The color characteristic of step 708, vehicle based on acquisition, establishes color characteristic distributed model.
