1231922 玖、發明說明： 【發明所屬之技術領域】 本發明係關於一種多重扣款整合式多車道自由車流電子收 ♦ 費•系統，特別為一種執法單元與扣款單元獨立且具有電子收費 與門禁管理之功能，可結合奉牌黑名單資料庫，做為贓車查緝 等應用之多重扣款整合式多車道自由車流電子收費系統。 【先前技#?】 習用的電子收費系統，通常是以專用短程通信協議 (DSRC)、車輛定位系統(vps)或微波單一扣款單元為電子收費系 、、先之扣執單元，並無法有效整合各種扣款單元的優點，舉例來 說，專用短程通信協議容易受到太陽及隔熱紙的影響，車輛定 位系統容易受到衛星定位不到的問題，微波容易受到外界干擾 及摻有金屬材質的隔熱紙影響。且當系統在轉換扣款單元時， 則執法單元與扣款單元的相關程式就必需相對配合更新。 由此可見，上述習用方式仍有缺失，實非一良善之設計者， 而亟待加以改良。 本案創作人鑑於上述習用所衍生的各項缺點，乃亟思加以 改進創新，並經多年苦心孤詣研究後，終於成功研發成本件多 重扣款機制之整合式多車道自由車流電子收費系統。 Π务明内容】 本發明之目的之一在於提供一種具多重扣款機制之整合式 10 1231922 多車道自由車流電子收費系統，其可彈性使用不同扣款方式。 本發明之目的之二在於提供一種扣款單元與影像執法單元 獨立之多重扣款整合式多車道自由車流電子收費系統。 可達成上述發明目的之多重扣款整合式多車道自由車流電 :費系統係由影像執法單元、扣款單元、後端處理單元所組 成。為有效整合各種扣款單元的優點與減少各種扣款單元的缺 點，扣款單元可以採用車輛定位系統（VPS)、專用短程通信協議 (DSRC)或車輛定位系統加專用短程通信協議三種方式。車輛定 位系統是由通用分組無線業務（GPRS)無線通訊單元、全球定位 系統（GPS)車輛定位單元、個人數位助理（PDA)車上單元所組 成。其扣款流程為事先預前定義扣款區域及執法區，再利用全 球定位系統車輛定位單元所擷取資料將全球定位系統結果與扣 款區比對，若於扣款區内，就會利用通用分組無線業務進行通 訊扣款並於執法區取像存證，若使用者未依規定扣款，則後端 匹配模組會加以整合判斷，做為逃費、違規告發之依據，並於 後端記錄查核。專用短程通信協議是由車上讀卡機（Vehicle Control Unit，VCU)與車道系統（Road Top Unit，RTU)所組成， 會同時驅動控制卡板，而控制卡板便會設定車道系統(RTU)，以 做通訊之準備。影像執法單元由取像單元、車牌辨識單元、接 圖（Image Registration)單元及車型辨識單元所組成。取像單元包 含前照（後照）感應單元、前照（後照）光耦合（CCU)攝影機、影像 π 1231922 擷取卡（Frame Grabber)、數位輸出入卡（Digital 所組成。在程式的執行過程中，會以問卷的方式每間隔一定時 間的掃猫週期去檢查㈣卡板是否有資料進來，而控制卡板會 以每間隔-定時間的掃晦週期去檢查車道系統是否有車上讀卡 機進入通訊區。當有車輛進入前照(後照)的感亭區域且車上有車 上續卡機單元，則扣款單元會執行扣款動作。 當車輛定位系統與專用短程通信協議整合使用時，必須事 先預前定義扣款區域及執法區，且t車輛進人扣款區時，如果 全球定位系統因衛星^位失敗*失效時，可以專用短程通信協 議來輔助；同理，如果專用短程通㈣議社陽光或隔熱紙的 影響而失效時’則可以車輛定位系統來輔助；如果車輛定位系 統與專用短程通信協議同時動作時，職端可以利用匹配來整 合扣款資料；如果車輛定㈣誠專驗料耗仙時失效 時，則也還有執法系統當作最後的防線。 此外，執法單元與扣款單元是分別獨立的個體，所有的匹 配動作都是在後端進行，執法單元只是提供車牌影像、辨識結 果及通行域給後端，而扣款單元只是提供扣款紀錄給後端， 所以如果扣款單元損_，並不會造絲法單^ 用 理如果㈣單元損壞時，並不會造成扣款單元無法執行，所以 執法系統具有很強的獨立性與穩定性，也因此不論扣款系統採 那-種扣款方式’執法系統都不必重新修改影像執法單元的 12 1231922 程式，具有很大的彈性。 【實施方式】 請參閱圖一所示，係本發明所提供之系統架構流程圖。由 於影像執法單元1與扣款單元2(由車輛定位系統及專用短程通 信協議組成）是分別獨立的個體，所有的匹配動作都是在後端處 理單元3(由電腦自動匹配單元31、人工比對單元32及罰單寄 發肩制33組成）進行，影像執法單元1只是提供車牌影像、辨 識結果及通行紀錄給後端3,而扣款單元2只是提供扣款紀錄給 後端3，所以如果扣款單元2損壞時，並不會造成執法單元1 無法執行，同理如果執法單元1損壞時，並不會造成扣款單元2 無法執行，所以執法系統具有很強的獨立性與穩定性，也因此 不論扣款系統採用那一種扣款方式，執法系統都不必重新修改 影像執法單元1的程式，具有很大的彈性。 由於取像單元11藉由前（後）照感應單元12觸發取像，所以 可以避免因不同的車速而導致的取像失敗或因大小車混合所導 致的取像失敗。此外，為避免產生同一台車多次取像導致取像 資料過多而造成後端比對機制的困擾，所以我們採用鎖定（lock) 的方法來解決此一問題。所謂鎖定是指當前（後）照感應單元12 感應到車輛進入感應區後自動取像，並鎖定住取像單元，直到 前（後）照感應單元12感應車輛離開感應區。另可增設一黑名單 管理單元4,係利用影像執法單元所辨識出來的車牌號碼與扣款 13 1231922 單元2所辨識出來的扣款單元ID來查詢黑名單資料庫41，將 來自黑名單資料庫41之資料匯入電腦自動匹配單元3 1進行整 合，若查詢出來是黑名單則交由警察單位處理。 請參閱圖二，為本發明之系統資料流程圖。由於是採用登 記制，在正常使用下，扣款單元ID與車牌號碼在資料庫當中 是以一對一方式對應的，當車牌辨識5後，若自動辨識成功51， 則判斷影像中車號是否有登記52，結果區分成二大類，亦即影 像沖車號係無登記者或影像中車號係有登記者，且若車牌辨識 成功，則寄發罰單。無登記者原則上不扣款521，但若是因為車 號無法自動辨識者51，還必需經由後端人工比對機制53處理， 才不致於有誤罰的可能性。而有登記者則可與扣款系統的扣款 單元識別碼（ID)交由後端人工處理機制53進行自動比對。如果 後端人工比對機制53人工辨識的結果發現車牌取像成功54,則 又可依扣款成功與否55區分成二大類，亦即車牌取像成功且扣 款成功56及車牌取像成功但扣款失敗57二大類。如果沒有取 像資料，則又可依扣款情形區分成二大類，亦即車牌取像失敗 但扣款成功58及車牌取像失敗且扣款失敗59二大類。當然， 只有車牌取像成功但扣款失敗才需寄發罰單571。當然，也就是 因為我們採用登記制，所以不會有因扣款單元號碼與車牌號碼 匹配錯而誤罰。 請參閱圖三，為本發明之四車道的光耦合攝影機架設位置 14 1231922 圖。如圖所示，我們分別將上行的前照光耦合攝影機命名為 UF1〜5，上行後照的光耦合攝影機命名為UB1〜5，下行的前照 光耦合攝影機命名為DF1〜5,下行的後照光耦合攝影機命名為 DB1〜5。在正常行駛的情況下，如果上行車輛感應區4(6)觸發， 則UF2(UF4)會進行取像；如果是下行車輛感應區1(3)觸發，則 DF2(DF4)會進行取像。當車輛變換車道時，如果使上行車輛感 應區5觸發，則UF1、UF3、UF5會進行取像；如果使下行車輛 感應區2觸發，則DF1、DF3、DF5會進行取像。為避免徒增後 端A工處理機制的困擾，如果車牌辨識程式能成功辨識UF3或 DF3的車牌影像，貝U UF1、UF5或DF1、DF5並不會使用；相 對地，如果車牌辨識程式無法成功辨識UF3或DF3的車牌影 像，則會自動對UF1、UF5或DF1、DF5進行車牌辨識，並將 結果送交後端人工比對機制進行自動比對。 由於多車道自由車流可能會同時摻雜大貨車、小轎車，則 小轎車的車牌很有可能被大貨車遮住，所以，我們提出使用後 照的方式來加以補強。亦即，當偵測到平均車速過慢，則自動 啟動後照功能，換言之，在塞車的情況下，如果上行車輛感應 區1觸發，則UF2、UB2會進行取像；如果上行車輛感應區3 觸發，則UF4、UB4會進行取像；如果是下行車輛感應區4觸 發，則DF2、DB2會進行取像；如果是下行車輛感應區6觸發， 則DF4、DB4會進行取像；當車輛變換車道時，如果使上行車 15 1231922 輛感應區2觸發，則UF1、UF3、UF5、UB1、UB3、UB5會進 行取像；如果使下行車輛感應區5觸發，則DF1、DF3、DF5、 DB1、DB3、DB5會進行取像。為避免徒增後端人工處理機制的 困擾，如果車牌辨識程式能成功辨識UF3或DF3的車牌影像， 貝1J UF1、UF5、UB1、UB5 或 DF1、DF5、UB1、UB5 並不會使 用；相對地，如果車牌辨識程式無法成功辨識UF3、UB3或DF3、 DB3的車牌影像，貝ij會自動對UF1、UF5、UB1、UB5或DF1、 DF5、DB1、DB5進行車牌辨識，並將結果送交後端人工處理機 制進行自動比對。此一方法形同第一位專家先利用UF2、UF3、 UE4或DF2、DF3'DF4的前照影像來進行檢驗車牌取像是否成 功’如果不成功，才動用第二位專家針對UF1、UF5或DF1、 DF5的前側照影像進行檢驗，如果還不成功，則動用第三位專 家針對UB2、UB3、UB4或DB2、DB3、DB4的後照影像進行 才欢驗車牌取像是否成功，如果不成功，再動用第四位專家針對 的後側照影像UB1、UB5或DB1、DB5進行檢驗，最後一道關 卡’則是操作員這個第五位專家來進行人工比對。運用這種多 重專家的方式可有效減少取像失敗的機率，大幅提昇電子收費 系統的可靠度。雖然會增加取像資料量，但利用多重專家的方 式可加速系統運算時間。使用前後照搭配的方式，可有效解決 塞車時大貨車遮蔽小轎車的問題，也可避免為規避繳費而將車 距杈小所導致之取像失敗。 16 1231922 。、在本發明當中，扣款單元可以制車輛定位系統、專用短 程通信協議或車輛定位系統加專用短程通信協議三種方式。車 輛定位系統是由通用分組無線業務無線通訊單元、全球定位系 統車㈣位單元、個人數位助理(PDA)車上單元所組成。 μ私為事s預前定義扣款區域及執法區，再利用全球定位系统 車輛定位單元所操取資料將全球定位系統結果與扣款區比對， 若於扣款區内，就會利用通用分組無線業務進行通訊扣款並於 執法區取像存證，若使用者未依規定扣款，則後端匹配模組會 加以整合判斷，做為逃費、違規告發之依據，並於後端記錄查 核。專用短程通信協議是由車上讀卡機與車道系統所組成，會 同‘時驅動㈣卡板’而控制卡板便會設定車道系統，以做通訊 之準^在程式的執行過程中，會以輪詢的方式每間隔一定時 門叫跑週期去檢查控制卡板是否有資料進來，而控制卡板會 以每間隔一定時間的掃猫週期去檢查車道系統是否有車上讀卡 機進入通㈣。當有車輛進入前照（後照）的感應區域且車上有車 上讀卡機早7C ’則扣款單元會執行扣款動作。當車輛定位系統 、通彳。協4整合使用時，必須事先預前定義扣款區域 «法區’且當車輛進入扣款區時’如果全球定位系統因衛星 、而失效時，可以專職程通信協議來輔助；同理，如 程通L協4因太陽光或隔熱紙的影響而失效時，則可 以車輛定位系統來輔助；如果車輛定位系統與專用短程通信協 17 1231922 翻時動作時，則後端可以湘匹配來整合扣款資料，·如果車 輛定位系統及專用短程通信協議同時失效時，則也還有執法系 統當作最後的防線。 / ” 如圖四所不，後端人工比對機制由車辆通行資料自動 匹配單元與人工操作介面單元所組成。車輛通行資料自動匹配 單兀會先將扣款與執法系統匯入資料庫對應表格中然後第一 階段依照本身車道與跨車道之順序，在一定的時間區間之内， 將扣款之扣款單元登記車號與執法辨識車號進行比對，若完全 相同者，紀錄彼此之匹配關係。第二階段依照本身車道血ϋ 道之順序，在一定的時間區間之内，將扣款之扣款單元登纪車 號與執法辨識車_匕對，若四個(含)以上車牌號碼以上相同 紀錄彼此之匹配關係。若第―、二階段完成後，仍狹沒有 完成匹配關係，則依照本身車道與跨車道之順序，在一定的時 間區間之内’利用扣款之時間與執法時間計算時間差（計算至微 秒），將時間差最接近者，顯示在勞幕上供操作者進行人工比 對。若最後有車牌影像但沒有扣款單元仍則逕行告發。由於傳 統的執法系統，為了取得完整的全景，所以分成多台攝影機分 別取像’但是如果後端匹两生 傻化匹配失敗，則操作員必須從大量的圖形 棺當中找㈣聯性，但比較沒有連續”的感覺。為解決此一 問題提出使用接圖（ImageRe細ation)的技術將同一時間多台 攝影機之個卿像加以整合成環場影像，讓操作員在進行人工 18 1231922 比對的時候，能夠比較有連續空間的感覺，也可以簡化操作員 人工比對的時間。 此外，為因應不同車型使用不同的價錢，本發明提出利用 雷射感測器進行車型辨識，利用雷射感測器所連續取得之輪廓 (profile)資訊加以判斷車型，如果系統應用在電子收費系統，則 系統可依據影像執法系統所判斷出來之車輛車型與車上讀卡機 所設定的車型來做判斷，如果不同，則影像執法系統就可以逕 行開立罰單。 後端人工比對機制使用者介面單元在本發明當中是以網頁 的方式呈現。人工操作介面可分為單筆式及多筆式。單筆式一 次處理一筆匹配資料，在左方顯示單筆扣款資料（包含車牌辨識 單元所辨識出來的車牌號碼、扣款單元所取得的扣款單元識別 碼j[ID)、與扣款單元識別碼匹配的車牌號碼、取像時間、扣款時 間、曾經經過的車道、平均車速、黑名單狀態等），右方列出可 能匹配之執法資料，在可能的匹配取像圖片上加上可能性的百 分比，以利操作員進行判斷。並提供核取方塊以人工勾選的方 式勾選匹配資料（可複選），完成後按鈕進行下一筆之匹配動作。 由於可能同一台車多次取像，所以後端處理機制採用可複選的 方式將取像資料進行整合，以減少不明影像的張數。此外，操 作員可以藉由人眼辨識車牌號碼與網頁所提供之資料來判斷那 幾張取像資料應該與扣款資料進行整合。但是由於隔熱紙所造 19 1231922 成的紅外線折射、反射、繞射或網路傳輸延遲或雜訊所造成的 延遲等等因素所導致的執法時間順序未必等於扣款時間順序。 因此如果單純使用時間來當做比對的重要因素可能會造成比對 錯誤°因此本發明提供了另外-種模式，也就是多筆式。多筆 式-，可同時看到在一時間區間内的所有扣款資料及取：資 料’操作者可㈣比較宏觀的角度來進行人王比 樣地’在可能的匹配取像圖片上加上可能性的百分比，以利操 作員進行判斷。 不論是單筆式或多筆式使用者操作介面t中的可能性分 析’均係以車牌賴單元所辨識出來的車牌號碼、與扣款單元

invention belongs] The present invention relates to a multi-debit integrated multi-lane free traffic flow electronic collection fee system, particularly a law enforcement unit and debit unit independent with electronic toll collection and access control The management function can be combined with the Fengpai blacklist database as an integrated multi-lane free traffic flow electronic toll collection system for multiple deductions such as stolen vehicle detection. [PRIOR ART #?] The conventional electronic toll collection system usually uses a dedicated short-range communication protocol (DSRC), a vehicle positioning system (vps), or a microwave single debit unit as the electronic toll collection system. The first deduction unit is not effective. Integrate the advantages of various debit units. For example, dedicated short-range communication protocols are easily affected by the sun and thermal insulation paper. Vehicle positioning systems are vulnerable to satellite positioning problems. Microwaves are vulnerable to external interference and metal materials. Hot paper effect. And when the system is converting the debit unit, the relevant programs of the law enforcement unit and the debit unit must be updated in coordination. It can be seen that the above-mentioned customary methods are still lacking. They are not a good designer and need to be improved. In view of the various shortcomings arising from the above-mentioned custom, the creator of this case was eager to improve and innovate. After years of painstaking research, he finally successfully developed an integrated multi-lane free-flow electronic toll collection system with a cost-reduction mechanism. Contents of the matter] One of the objectives of the present invention is to provide an integrated 10 1231922 multi-lane free traffic flow electronic toll collection system with multiple debit mechanisms, which can flexibly use different debit methods. Another object of the present invention is to provide an integrated multi-debit integrated multi-lane free traffic flow electronic toll collection system independent of a debit unit and an image enforcement unit. The multi-deduction integrated multi-lane free car current and electricity system that can achieve the above-mentioned purpose of the invention is composed of an image enforcement unit, a deduction unit, and a back-end processing unit. In order to effectively integrate the advantages of various debit units and reduce the shortcomings of various debit units, the deduction unit can adopt three methods: vehicle positioning system (VPS), dedicated short-range communication protocol (DSRC), or vehicle positioning system plus dedicated short-range communication protocol. The vehicle positioning system is composed of a general packet radio service (GPRS) wireless communication unit, a global positioning system (GPS) vehicle positioning unit, and a personal digital assistant (PDA) on-board unit. The deduction process is to define the deduction area and law enforcement area in advance, and then use the data captured by the GPS vehicle positioning unit to compare the GPS results with the deduction area. If it is in the deduction area, it will use The general packet wireless service conducts communication deductions and obtains image deposit certificates in the law enforcement area. If the user does not deduct according to the regulations, the back-end matching module will integrate the judgments as the basis for evading charges and reporting violations, and later End record check. The dedicated short-range communication protocol is composed of the Vehicle Control Unit (VCU) and the Road Top Unit (RTU), which will drive the control card at the same time, and the control card will set the RTU. To prepare for communications. The image law enforcement unit consists of an image acquisition unit, a license plate recognition unit, an image registration unit, and a vehicle identification unit. The image capture unit consists of a front-light (back-light) sensor unit, a front-light (back-light) optical coupling (CCU) camera, an image π 1231922 frame grabber, and a digital input-output card (Digital.) During the process, a questionnaire method will be used to scan the cats every certain period of time to check whether the card board has data in, and the control board will check the lane system to check whether there is a car reading on the interval-fixed time. The card machine enters the communication area. When a vehicle enters the kiosk area of the front (backlight) and there is a card renewal unit on the car, the deduction unit will perform the deduction action. When the vehicle positioning system and a dedicated short-range communication protocol For integrated use, the deduction area and law enforcement area must be defined in advance. When the vehicle enters the deduction area, if the global positioning system fails due to satellite failure *, it can be assisted by a dedicated short-range communication protocol. Similarly, If the dedicated short-range communication system fails due to the influence of sunlight or thermal insulation paper, then the vehicle positioning system can assist; if the vehicle positioning system and the dedicated short-range communication protocol operate at the same time, The staff can use the matching to integrate the deduction data; if the vehicle Ding Chengcheng special inspection fails, the law enforcement system is also used as the last line of defense. In addition, the law enforcement unit and the deduction unit are separate entities. All matching actions are performed on the back end. The law enforcement unit only provides the license plate image, recognition results, and transit domain to the back end, while the deduction unit only provides the deduction record to the back end, so if the deduction unit is damaged, and Will not make a single wire method ^ If the unit is damaged, it will not cause the deduction unit to be executed, so the law enforcement system has strong independence and stability, so regardless of the deduction system-what kind of deduction The “law enforcement” system does not need to modify the 12 1231922 program of the image enforcement unit, which has great flexibility. [Embodiment] Please refer to Figure 1, which is a flowchart of the system architecture provided by the present invention. Since the image enforcement unit 1 and Debit unit 2 (composed of a vehicle positioning system and a dedicated short-range communication protocol) is an independent individual, and all matching actions are performed in the back-end processing unit 3 ( Computer automatic matching unit 31, manual comparison unit 32 and ticket delivery shoulder system 33). Image law enforcement unit 1 only provides license plate images, recognition results and traffic records to back end 3, while deduction unit 2 only provides deductions. The records are given to the back end 3, so if the deduction unit 2 is damaged, the law enforcement unit 1 cannot be executed. Similarly, if the law enforcement unit 1 is damaged, the deduction unit 2 cannot be executed, so the law enforcement system has a very Strong independence and stability, so no matter which deduction method is used by the deduction system, the law enforcement system does not need to re-modify the program of the image law enforcement unit 1, which has great flexibility. Because the image acquisition unit 11 uses the front (back ) The image sensing unit 12 triggers image acquisition, so it is possible to avoid image acquisition failure caused by different vehicle speeds or image acquisition failure caused by mixing of large and small cars. In addition, in order to avoid the trouble of back-end comparison mechanism caused by too many acquisition data caused by multiple acquisitions of the same vehicle, we adopt a lock method to solve this problem. The so-called lock means that the current (back) photo sensing unit 12 automatically captures an image when the vehicle enters the sensing area, and locks the image capturing unit until the front (back) photo sensing unit 12 senses that the vehicle leaves the sensing area. In addition, a blacklist management unit 4 can be added, which uses the license plate number and deduction identified by the image enforcement unit 13 1231922 The deduction unit ID identified by unit 2 to query the blacklist database 41, which will come from the blacklist database The data of 41 is imported into the computer automatic matching unit 31 for integration. If the query is a blacklist, it will be handed over to the police unit for processing. Please refer to FIG. 2 for a system data flow chart of the present invention. Due to the registration system, under normal use, the deduction unit ID and the license plate number correspond one-to-one in the database. After the license plate recognition is 5, if the automatic recognition is successful, 51, determine whether the vehicle number in the image is There are registrations 52, and the results are divided into two categories, that is, those who have no registration in the image or those who have registration in the image, and if the license plate is successfully identified, a ticket is issued. Those who do not register will not be charged 521 in principle. However, if the car number cannot be identified automatically by the person 51, it must also be processed by the back-end manual comparison mechanism 53 to avoid the possibility of mistaken punishment. Those who have registered can hand over the debit unit identification code (ID) of the deduction system to the back-end manual processing mechanism 53 for automatic comparison. If the result of manual recognition of the back-end artificial comparison mechanism 53 finds that the license plate is successfully acquired 54, it can be divided into two categories according to the success or failure of the deduction 55, that is, the license plate is successfully acquired and the charge is successfully 56 and the license plate is successfully acquired. But the chargeback failed 57 two major categories. If there is no image acquisition data, it can be divided into two categories according to the deduction situation, that is, the license plate acquisition fails but the deduction is successful58 and the license plate acquisition fails and the deduction fails59. Of course, only if the license plate is successfully acquired but the deduction fails, a ticket 571 needs to be sent. Of course, because we use the registration system, there will be no penalty due to the mismatch between the debit unit number and the license plate number. Please refer to FIG. 3, which shows the position of the photo-coupling photography rack for the four lanes of the present invention. As shown in the figure, we named the upstream front-coupled camera as UF1 ~ 5, the upstream back-coupled camera as UB1 ~ 5, the downstream front-coupled camera as DF1 ~ 5, and the downstream back-coupled camera. The cameras are named DB1 ~ 5. Under normal driving conditions, if the upward sensing zone 4 (6) is triggered, then UF2 (UF4) will acquire images; if the downward sensing zone 1 (3) is triggered, DF2 (DF4) will acquire images. UF1, UF3, and UF5 will acquire images when the upshift vehicle sensing area 5 is triggered when the vehicle changes lanes; if DF1, DF3, DF5 will be acquired if the downshift vehicle sensing area 2 is triggered. In order to avoid the trouble of increasing the back-end A processing mechanism, if the license plate recognition program can successfully recognize the license plate image of UF3 or DF3, the U UF1, UF5 or DF1, DF5 will not be used; on the contrary, if the license plate recognition program cannot succeed Recognize the license plate image of UF3 or DF3, then automatically recognize the license plate of UF1, UF5 or DF1, DF5, and send the result to the back-end manual comparison mechanism for automatic comparison. Since the multi-lane free traffic may be mixed with large trucks and cars at the same time, the license plate of the cars is likely to be covered by the large trucks. Therefore, we propose to use the backlight method to reinforce them. That is, when the average vehicle speed is detected to be too slow, the backlight function is automatically activated. In other words, in the case of a traffic jam, if the upward sensing area 1 triggers, UF2 and UB2 will take an image; if the upward sensing area 3 If triggered, UF4 and UB4 will acquire images; if it is triggered by downward vehicle sensing area 4, DF2 and DB2 will acquire images; if it is triggered by downward vehicle sensing area 6; DF4 and DB4 will acquire images; when the vehicle changes In the lane, if the upside 15 1231922 sensing area 2 is triggered, UF1, UF3, UF5, UB1, UB3, and UB5 will be captured; if the downstream vehicle sensing area 5 is triggered, DF1, DF3, DF5, DB1, DB3 and DB5 will capture images. In order to avoid the trouble of increasing the back-end manual processing mechanism, if the license plate recognition program can successfully recognize the license plate image of UF3 or DF3, Bay 1J UF1, UF5, UB1, UB5 or DF1, DF5, UB1, UB5 will not be used; relatively If the license plate recognition program cannot successfully recognize the license plate image of UF3, UB3 or DF3, DB3, Beiij will automatically recognize the license plate of UF1, UF5, UB1, UB5 or DF1, DF5, DB1, DB5 and send the result to the backend. Manual processing mechanism for automatic comparison. This method is similar to the first expert first using UF2, UF3, UE4 or DF2, DF3 'DF4 to check whether the license plate acquisition was successful. If it is not successful, then use the second expert to target UF1, UF5 or DF1, DF5's front side view images are checked. If it is not yet successful, use a third expert to perform a back-up image of UB2, UB3, UB4 or DB2, DB3, DB4 to check whether the license plate acquisition is successful. If not, Success, then use the backside image UB1, UB5 or DB1, DB5 for the fourth expert to check, and the final level is the fifth expert, the operator, to perform manual comparison. The use of this multi-expert approach can effectively reduce the chance of image acquisition failure and greatly improve the reliability of the electronic toll collection system. Although it will increase the amount of image data, using multiple experts can speed up the system operation time. The combination of front and rear photos can effectively solve the problem of large trucks hiding cars in traffic jams, and can also avoid the failure of image acquisition caused by the small distance between cars to avoid payment of fees. 16 1231922. In the present invention, the deduction unit can be made into a vehicle positioning system, a dedicated short-range communication protocol, or a vehicle positioning system plus a dedicated short-range communication protocol. The vehicle positioning system is composed of a general packet wireless service wireless communication unit, a global positioning system vehicle positioning unit, and a personal digital assistant (PDA) on-board unit. μ Private defines the deduction area and law enforcement area in advance, and then uses the data processed by the GPS vehicle positioning unit to compare the GPS results with the deduction area. If it is in the deduction area, it will use the general The group wireless business conducts communication deductions and obtains image deposit certificates in the law enforcement area. If the user does not deduct according to the regulations, the back-end matching module will integrate the judgments as the basis for evading charges and reporting violations. Record review. The dedicated short-range communication protocol is composed of an on-board card reader and a lane system. Together with the 'simultaneous driving of the card board', the control card board will set the lane system for communication standards. During the execution of the program, The polling method calls the door to run at a certain interval to check whether the control card board has data in, and the control card board will check the lane system to check whether the card reader in the lane enters the pass at a certain interval. . When a vehicle enters the sensing area of the front light (back light) and there is a card reader on the car as early as 7C, the deduction unit will perform the deduction action. When the vehicle positioning system, communication. For the integrated use of protocol 4, you must define the deduction area «law area» in advance and when the vehicle enters the deduction area 'if the global positioning system fails due to satellites, you can use a full-time communication protocol to assist; similarly, such as When Chengtong L Association 4 fails due to the influence of sunlight or thermal insulation paper, it can be assisted by the vehicle positioning system; if the vehicle positioning system and the dedicated short-range communication protocol 17 1231922 are turned over, the back end can be integrated to match. Deduction information. If the vehicle positioning system and the dedicated short-range communication protocol fail at the same time, there is also a law enforcement system as the last line of defense. / ”As shown in Figure 4, the back-end manual comparison mechanism is composed of an automatic matching unit for vehicle traffic data and a manual operation interface unit. The automatic matching unit for vehicle traffic data will first match the deduction with the law enforcement system into the database. The first stage of the form then compares the debited unit registration vehicle number with the law enforcement identification vehicle number within a certain period of time in accordance with the order of its own lane and cross lanes. Matching relationship. In the second stage, according to the order of the blood lanes of its own lane, within a certain time interval, the deducted deduction unit registration number and law enforcement identification car _ dagger pair, if there are four or more license plates The matching relationship between the same records above the same number. If the matching relationship is still not completed after the completion of the first and second stages, according to the order of its own lane and cross lanes, within a certain period of time, 'use the time of deduction and law enforcement. Calculate the time difference (calculated to microseconds), and display the time difference closest to the labor curtain for manual comparison by the operator. If there is a license plate image but no The debit unit is still reporting. Due to the traditional law enforcement system, in order to obtain a complete panorama, it is divided into multiple cameras to take images separately. However, if the back-end pairing fails, the operator must use a large number of graphic coffins. I find couples, but I do n’t have a sense of continuity. In order to solve this problem, it is proposed to use the ImageRefinement technology to integrate the images of multiple cameras at the same time into a ring field image, so that the operator can have more continuous when performing manual 18 1231922 comparison. The sense of space can also simplify the time for operators to manually compare. In addition, in order to use different prices for different vehicle models, the present invention proposes to use a laser sensor to identify the vehicle model, and to use the profile information continuously obtained by the laser sensor to determine the vehicle model. If the system is applied to an electronic toll collection system , The system can make a judgment based on the vehicle model determined by the image enforcement system and the model set by the card reader on the car. If they are different, the image enforcement system can issue a ticket. The user interface unit of the back-end manual comparison mechanism is presented in the form of a web page in the present invention. Manual operation interface can be divided into single pen type and multi-pen type. Single-handed processing of one piece of matching data at a time, displaying single charge data on the left (including the license plate number identified by the license plate recognition unit, the deduction unit identification code j (ID) obtained by the deduction unit, and the deduction unit Identification number matching license plate number, acquisition time, deduction time, lanes passed, average speed, blacklist status, etc.), the law enforcement information of possible matches is listed on the right, and possible pictures are added to the possible matching images The percentage of sexuality for the operator's judgment. It also provides a check box to manually select the matching data (can be selected), and then press the button to perform the next matching action. Since the same vehicle may take images multiple times, the back-end processing mechanism integrates the acquisition data in a selectable manner to reduce the number of unknown images. In addition, the operator can judge by human eyes the license plate number and the information provided on the webpage to determine which image acquisition data should be integrated with the deduction data. However, due to factors such as infrared refraction, reflection, diffraction, or network transmission delay or delay caused by noise caused by thermal insulation paper, the law enforcement time sequence may not be equal to the deduction time sequence. Therefore, if time is simply used as an important factor for comparison, the comparison error may be caused. Therefore, the present invention provides another mode, that is, a multi-stroke method. Multi-pen-type, you can see all the deduction information and collection in a time interval at the same time: the data 'operator can compare the macro perspective to perform the king-to-many comparison sample' Add the possible matching image Percentage of possibilities for operator judgment. No matter whether it is a single-stroke or multi-stroke user interface t, the possibility analysis 'is based on the license plate number identified by the license plate unit, matching the deduction unit identification code, the license plate number, and the car's color'. Factors such as #material, order of material collection, order of charge time, and lanes used to calculate the percentage of probability are combined with the concept of weight. ^ When the system is converted, the law enforcement program must be updated. Because the law enforcement unit and the deduction unit are separate, all matching actions. ♦ The present invention has the following advantages when compared with other conventional technologies. The previous image law enforcement system was usually a dedicated short-range communication protocol, a vehicle The positioning system or microwave system is used in conjunction with the image law enforcement program. It does not have integrated identification results and communication is performed on the back end. The law enforcement unit only provides license plate images, so it is reasonable to record the back end while the deduction unit only provides When the deduction record damages the back-end fruit deduction unit, the shirt will cause the law enforcement unit to fail to execute. 20 1231922 Cui Zhixin will not cause the deduction unit to fail to execute, so the law enforcement system has strong independence and stability. Therefore, no matter which deduction method is used for the deduction system, the law enforcement system does not have to modify the program of the image law enforcement unit, which has great flexibility. Because the special short-term private communication protocol is easily affected by the sun and thermal insulation paper, the vehicle position is not easy to reach the satellite, and the microwave is easily affected by external disturbance and the thermal insulation paper mixed with metal shells. When the vehicle positioning system is integrated with the dedicated / pass U4, the deduction area and law enforcement area must be defined in advance, and when the vehicle enters the deduction area, if the global positioning system fails due to satellite positioning failure, it can be dedicated A short-range communication protocol is used to assist. Similarly, if the dedicated M private communication suggests that it fails due to the influence of sunlight or thermal insulation paper, it can be assisted by a vehicle positioning system. If the vehicle positioning system and the dedicated short-range communication protocol operate simultaneously, Then the back end can use matching to integrate the charge data; if the vehicle positioning system and the dedicated short-range communication protocol fail at the same time, there is also the law enforcement system as the thickest line of defense; also because the imaging unit and the charge unit are The law enforcement unit and the deduction unit are independent, and the law enforcement single law has the flexibility to accept a variety of different deduction units.
