the other is derived from the continuous data of the camera l, which together constitute the pre-formation of real-time vehicle location, speed and The number of data, referred to as real-time data. 实时数据分为两路进行传输:a.输入到预编队数据处理计算机,用于生成理想的预编队图像;b.输入到时实位置生成计算机,用于生成简单准确的实时图像。 Real-time data for transmission is divided into two paths: a data input to the pre-formation processing computer for generating ideal pre-image formation; B input to the computer to generate real locations, for generating a simple and accurate real-time images. 现在分别逐一来看则两个过程是如何实现的,首先考虑预编队图像的生成。 Now look at the two processes separately one by one is how to achieve, first consider the pre-generated image formation. a.预编队图像的生成:预编队数据处理计算机收到实时数据后,根据预先编好的程序进行计算,实时算出4条路左右行车道预编队队列的长度,密度和速度。 generating a pre-image formation: After the pre-formation data processing computer receives real-time data is calculated based on pre-programmed, the length is calculated in real time, density and velocity of about 4 lane road pre-formation queue. 在计算预编队队列的长度,密度和速度时,编程必须满足如下规则:预编队所要遵循的法则:l.基本关系式:预编队的车辆位置速度数量监测器与定位信号接收发射架之间的距离定义为预编队区总长度,用S表示。 When calculating the pre-formation queue length, density and velocity, programming must satisfy the following rules: rule pre-formation to be followed: L basic formulas: Vehicle Pre-formation of the position and speed quantity monitor the signal receiving between launchers Chief distance is defined as the length of pre-formation, represented by S. 编队车辆过路口的最大速率用(/_表示,满足:(2)换言之,若要提高编队通过路口的速度,就要增加预编队总长度,相应的车辆位置速度数量监测器的数量也要增加。设每一段A5需要一台车辆位置速度数量监测器,那么S共需要"台,即 Formation of the vehicle through the intersection with the maximum rate (/ _ expressed satisfied: (2) In other words, to increase the speed of formation through the intersection, it is necessary to increase the overall length of the pre-formation, the number corresponding to the number of vehicle position and speed monitor also increases Let each segment A5 requires a number of vehicle position and speed monitor, then the total required S "units, i.e.

"=丄. (3) "= Shang. (3)

这是车辆位置速度数量监测器与预编队总长度之间的关系。 This is the position relationship between the vehicle speed and the number of pre-formation monitor the total length.

2.对称性法则。 2. The law of symmetry. 3.两组迎面相向的预编队领头的车辆必须满足同时在路口中心 Two groups of pre-formation face facing the lead vehicle in the center of the intersection at the same time must satisfy

处,即定位信号接收发射架(8)处交汇错车;b.两组迎面相向的编队车辆速度严格相等,用o点表示路口中心处,两编队用"》两队表示。已。表示"编队o点处的速度,K。 At that intersection dipped positioning signal received at the transmit carrier (8);. B two facing oncoming vehicle speed formation strictly equal, with o represents the center of the intersection points, with two formations "" indicates two teams represented.., "Formation velocity at the point o, K. 表示6编队0点处的速度,用公式表示出来是: 6 indicates the formation rate of 0:00, is represented by the formula:

(4) (4)

速度是矢量,相加为0,表明两编队在O点速度相反,且相等。 Is the velocity vector sum is zero, indicating that the two opposite point O formation rate, and equal. 上式简明的表述了两编队所要满足的对称性法则。 The type concise representation of the symmetry of the two fleet rule to be met.

3. 编队满足匀速性法则。 3. The formation of uniform rules to meet. 在编队结東到编队解散之间,车辆必须保持匀速性, 匀速通过路口,直至编队解散。 In the formation of the junction between the east to the formation disbanded, the vehicle must maintain uniform resistance, constant speed through the intersection until the formation disbanded.

4. 编队长度。 4. Formation length. 设预编队之间的间隔距离为A/,根据对称性法则有 Pre-set separation distance between the formation of A /, in accordance with a law of symmetry

/。 /. =r,Afa"。=K (6) = R, Afa ". = K (6)

路况无车的间隔时间Ar为 Road car-free interval Ar is

△, = ^ = , (7) △, = ^ =, (7)

设预编队的长度为/,编队通过路口的时间是"那么 Formation of the pre-set length /, is the formation of the intersection passage time "so

f = ; < A, ( 8 ) f =; <A, (8)

这一条件保证了编队不发生冲突。 This condition ensures that the fleet does not conflict.

5. 右拐弯编队及左拐编队遵守的法则:编队分为三种a.直行编队;b.左拐弯 Rule 5. Turn right and left formation formation observed: a formation into three straight formations; B turn left.

编队;c.右拐弯编队。 Formation;. C Turn right formation. 在这三类编队中,直行编队和左拐弯编队会发生干涉,因 In these three formations, formations straight and turn left formations interference will occur, because

而要遵循上述所有法则,而右拐弯编队编队则可以和直行编队和左拐弯编队并行前进。 And to follow all these rules, and you can turn right and go straight formation formations formations and turn left formations advancing in parallel. 参见图四。 See Figure IV.

6. 人行道遵守的法则:在预编队交通流中,穿过马路和现有的在路口穿过马路的规则不同,有多个斑马路通道对行人开放,每一个斑马路通道设有红绿灯, 红绿灯的规则和现有路口的斑马路人行通道规则一致。 6. sidewalk compliance rule: formation of the pre traffic flow across the road at the intersection of the existing rules, and across the road is different from a plurality of channels open to pedestrian zebra, zebra channels each with traffic lights, traffic lights Pedestrian passage zebra consistent rules and rules of existing junctions. 多通道的开放减少了行人过马路的时间,提高了安全性。 Open multi-channel reduces the time pedestrians crossing the road and improve safety.

釆集的数据经预编队程序计算后,得到四个路口的预编队的计算结果: l.编队速度;2.编队车辆数;3.编队长度;4.编队车辆之间各车间距; 5.车辆在雷达测速仪的瞬态实际位置。 Bian data after the pre-set calculation program formation, formation of the pre-obtained results of the four junctions: l formation velocity; 2 formation number of vehicles; 3 formations length; 4-vehicle distance between each vehicle formation; 5..... transient actual position of the vehicle in the radar gun.

上述计算结果分为两路,第一路送到路口信号灯控制柜7中,控制信号灯6。 The results above is divided into two paths, a first path to the intersection signal control cabinet 7, the control lights 6. 第二路送到预编队图形生成计算机9中,釆用图像软件将实时编队结果变为直观的图像,再将该图像送入图像分析比对计算机11中。 The second path to the pre-formation graphics generation computer 9, preclude the use of software image formation result becomes intuitive real-time image, the image sent to the image analysis and then compared in the computer 11. b.实时图像的生成:八个摄像机1的图像是不适合用于预编队控制的,因为图像的视角不同,为了得到完美简洁的俯视图,,必须将实际车辆运行的图像输入实时简化图像生成计算机10中,利用图像识别软件对图像进行简化,得到计算机可识别的实时车辆位置图像。 b generate real-time images: eight camera image is not suitable for a pre-formation control, since the different view images in order to obtain a top view of FIG ,, simple perfect image must enter the actual running of the vehicle in real time computer image generation simplified 10, the image recognition software to simplify the image, the computer image in real time vehicle location recognizable.

上述两种图像(预编队图像和实时图像)送入图像分析比对计算机ll中,计算机将通过图像对比分析软件将上述两种图像(理论图像和实际图像)进行分析对比。 Both images (real-time image and the pre-image formation) into a computer image analysis than ll, the computer the above two images (theoretical and real images) are analyzed by comparing the comparison image analysis software. 自动判别车辆实际位置是否满足理想编队位置,如果实际位置符合理想编队位置,车辆实际位置图像变为绿色,如果实际位置不符合理想编队位置,车辆实际位置图像则变为红色(这一过程可通过图像处理软件来实现)。 Automatically determine the actual position of the vehicle meets the ideal formation position, if the actual location with the ideal formation position, the actual position of the image of the vehicle turns green, if the actual location does not meet the ideal formation position, the actual position of the image of the vehicle turns red (the process by image processing software to achieve). 色彩的改变可以使驾驶员对自己的车辆位置是否进入到正确的编队位置有一个直观的判断。 Can change the color of the driver has an intuitive judgments about whether to enter the location of their vehicle fleet to the correct position.

为了让驾驶员的判断更为准确,还需要提供一个路面的实际的背景图像,这一背景图像可以通过8个高清晰摄像机1拍摄实际的路况图像,并通过图像适配程序将实际路况图像与计算机图像相匹配,这样就获得了真实的路况图像的背景图像。 In order to make a more accurate judgment of the driver, also need to provide the actual background image of a road surface, the background image can take the actual road conditions image 1 through 8 high-definition camera, and the image fit the program will image and the actual road conditions computer image to match, so get a true picture of the background image of the road.

最终,将所有的图像在图像重叠合成计算机12中进行重叠合成,合成的图像就是预编队所需要的最终图像,称为预编队控制图像。 Eventually, all of the images in the image synthesizing computer 12 in overlapping superimposed, synthetic pre-final image formation is desired, called a pre-image formation control. 该图像分两路进行传输, 一路传送到大屏幕显示器13;另一路送到信号发射台14,该图像通过无线电信号传输到微型车载接收及显示器15上。 Two routes of the image for transmission, transmitting all the way to the large-screen display 13; the other way to the signal transmitter 14, the image signal transmitted by radio to a receiver and a display on-board microcomputer 15.

这里还要解决在没有车载微型显示器的情况下,如何通过图像来进行预编队。 Here we have to solve in the absence of on-board micro-display cases, how to pre-formation through the image. 这里考虑利用监视大屏幕来进行预编队: Here consider the use of large-screen monitors to pre-formation:

监视大屏幕编队:预编队控制图像传送到的路口的大屏幕显示器13上,可以直观的观察到:l.队列的形状(队列形状用闪动的红色亮线显示出来);2.理想预编队位置;3.车辆的实际位置;4.进入到编队位置的实际情况。 Large-screen monitor formation: junctions in pre-formation of the image to the large screen display 13, can be visually observed: L shape queue (queue shape of flashing red bright line displayed); 2 over the pre-formation. position;. the actual position of the vehicle 3; 4 into actual formation position. 驾驶员可以从大屏幕上一目了然的看到。 The driver can see on the big screen at a glance. 未进入队列车辆的驾驶员看到自己未进入队列则及时调整,进入队列。 Driver of the vehicle did not enter the queue to see themselves did not enter the queue timely adjustment, enter the queue. 在队列中未调整好的车辆也可以通过大屏幕显示器13的图像及时进行调整,处于正确的编队位置。 Good unadjusted vehicle in the queue may be adjusted by a large-screen display image 13 in a timely manner, in the proper formation position.

车载微型显示器编队:参见图3,在汽车内有条件的装有车载接收及显示器15, 该监控具有预编队大屏幕显示器13相同的功能。 Car microdisplay formation: Referring to Figure 3, with conditions in the vehicle onboard receiver, and a display 15, which have the same functionality to monitor the pre-formation of large-screen displays 13. 车载接收及显示器15置于汽车驾驶室,其内部有一个定位信号发生器,该车辆的定位信号被定位信号接收发射架接收,送到数据分析中心中,确定该车辆在监控路段的位置,并和该监控路段的俯视图进行合成,得到该车位置的实时图像。 And a display 15 disposed onboard receiver of the vehicle cabin, which is positioned inside a signal generator, the vehicle positioning signal received by positioning signal reception launchers, to the data analysis center, determining the location of the vehicle in the monitored road section, and and a top view of the monitoring section of the synthesis, to obtain real-time image of the vehicle position. 把四条道路的所有定位信号与四条道路监控路段地形的俯视图进行合成,就得到了所有位置的实时图像。 All four roads positioning signal is synthesized with the top four roads to monitor road map terrain, you get real-time image at all locations. 将每一辆车简化为一个移动的具有速度位置的点,第/辆车用/,(^^,v,A),点的数据/,^,;^,^v。 Each vehicle has a speed reduced to a position of a mobile point, the first / vehicles with /, (^^, v, A), the point data /, ^,; ^, ^ v. 输入到数据分析中心计算机中,用专门的预编队程序进行分析和计算:l.确定预编队的队形,并用虛线方框表示出来;2.确定监控路段中第/辆车进入编队的所需的新的速度和位置y;'(x;,;c;,v;,v;)和路径soc^)和归队时间Ar,。 Input to the data analysis center computer, for the pre-formation with a special program analysis and calculation: l pre-determined formation formations, and represented by dashed boxes; 2 determines the first monitor road / vehicle enters the formation. new required speed and position y; '(x;,; c;, v;, v;) and the path soc ^) and time rejoin Ar ,. 这里新的速度和位置用/^»>;)表示。 Here the new speed and the position / ^ »>;) FIG.
