Description
本發明涉及系統與方法,特別涉及物體身分辨識系統及其自動辨識物體身分的方法。The invention relates to a system and a method, in particular to an object identity recognition system and a method for automatically identifying the identity of an object.
現有的監視系統僅有拍攝監視區域的能力,不具有辨識身分的能力,而必須仰賴人工判斷監看畫面來對是否有身分不明人員進入監視區域,這會耗費大量人力。Existing surveillance systems only have the ability to photograph the surveillance area, and do not have the ability to identify identities. Instead, they must rely on manual judgment of the monitoring screen to determine whether an unknown person enters the surveillance area, which will consume a lot of manpower.
目前另有一種具有人員偵測能力的監視系統,可基於影像辨識或紅外線感測來偵測人員是否進入監視區域。然而,前述監視系統同樣無法自動辨識進入監視區域的人員的身分。At present, there is another surveillance system with personnel detection capabilities, which can detect whether a person has entered the surveillance area based on image recognition or infrared sensing. However, the aforementioned surveillance system also cannot automatically identify the identity of persons entering the surveillance area.
此外,目前還有一種基於資料融合(data fusion)技術的監視系統被提出。於前述監視系統中,管理員必須事先手動配對各人員的身分資料與臉部影像以建立配對關係。於配對完成後,前述監視系統可依據所建立的配對關係來對所拍攝的人臉影像進行身分確認,以判斷進入監視區域的人員是否合法。然而,前述監視系統必須耗費大量時間與人力來預先進行資料配對。In addition, a monitoring system based on data fusion technology is currently proposed. In the aforementioned monitoring system, the administrator must manually match the identity data of each person and the facial image in advance to establish a matching relationship. After the pairing is completed, the aforementioned surveillance system may confirm the identity of the captured face image according to the established pairing relationship to determine whether the person entering the surveillance area is legal. However, the aforementioned monitoring system must spend a lot of time and manpower to perform data pairing in advance.

In addition, the identification card positioning module 22 is set to determine the location of each wireless identification card based on the signal strength corresponding to the lookup table 140 and each wireless identification card (or based on the scan settings corresponding to the lookup table 140 and each wireless identification card). The sub-area is used as the ID location.
於一實施例中,掃描裝置12平常處於休眠模式、待機模式等或其他低功耗模式。影像辨識模組20於監視影像中辨識出物體影像後觸發掃描裝置12進入工作模式以開始掃描監視區域。In one embodiment, the scanning device 12 is usually in a sleep mode, a standby mode, or other low power consumption modes.

The identification method of each embodiment of the present invention may be implemented by the identification system 10 shown in FIG. 1, FIG. 2, or FIG. 3 (the identification system 10 shown in FIG. 1 and FIG. 2 will be described later). The identification method of this embodiment includes the following steps.
步驟S10:控制裝置13(如第一控制單元111)控制影像擷取裝置11拍攝監視區域以獲得監視影像,並經由影像辨識模組20於監視影像中辨識進入監視區域的各物體的物體影像。Step S10: The control device 13 (such as the first control unit 111) controls the image capturing device 11 to capture a surveillance area to obtain a surveillance image, and identifies an object image of each object entering the surveillance area in the surveillance image through the image recognition module 20.
步驟S11:控制裝置13(如第一控制單元111或第三控制單元151)經由影像定位模組21決定各物體影像於監視區域中的影像位置。Step S11: The control device 13 (such as the first control unit 111 or the third control unit 151) determines the image position of each object image in the monitoring area via the image positioning module 21.
於一實施例中,影像擷取裝置11是以固定角度與焦段拍攝監視區域,而使得監視影像每次拍攝所顯示的監視區域的範圍皆相同。並且,管理員可預先對監視影像進行定義(如將監視影像的不同位置分別對應為現實的監視區域的不同子區域),並將對應規則儲存於儲存裝置14(如第一儲存單元112或第三儲存單元152)。藉此,控制裝置13可依據各物體影像於監視影像中的位置與對應規則來決定物體所在的子區域(即影像位置)。In one embodiment, the image capturing device 11 captures the monitoring area at a fixed angle and a focal length, so that the range of the monitoring area displayed every time the monitoring image is captured is the same. In addition, the administrator can define surveillance images in advance (for example, different locations of the surveillance images are respectively mapped to different sub-areas of the actual surveillance area), and store the corresponding rules in the storage device 14 (such as the first storage unit 112 or Three storage units 152). Thereby, the control device 13 can determine the sub-region (ie, the image position) where the object is located according to the position of each object image in the surveillance image and the corresponding rule.
於執行步驟S10-S11期間,控制裝置13(如第二控制單元121與第三控制單元151)可同時執行步驟S12-S13。步驟S12:控制裝置13(如第二控制單元121)經由掃描裝置12掃描監視區域以取得監視區域中各無線識別證的身分資料。During the execution of steps S10-S11, the control device 13 (such as the second control unit 121 and the third control unit 151) may execute steps S12-S13 simultaneously. Step S12: The control device 13 (such as the second control unit 121) scans the monitoring area through the scanning device 12 to obtain identity data of each wireless identification card in the monitoring area.
步驟S13:控制裝置13(如第二控制單元121或第三控制單元151)經由識別證定位模組22決定各無線識別證於監視區域中的識別證位置。Step S13: The control device 13 (such as the second control unit 121 or the third control unit 151) determines the identification card position of each wireless identification card in the monitoring area via the identification card positioning module 22.
於一實施例中,控制裝置13(如第二控制單元121)可依據各無線識別證的回應訊號所對應的訊號強度及方向來推算各無線識別證與掃描裝置12之間的距離,並依據所推算的距離與感應到各無線識別證時所掃描的子區域或掃描角度來決定各無線識別證所在的子區域(即識別證位置)。In an embodiment, the control device 13 (such as the second control unit 121) can estimate the distance between each wireless identification card and the scanning device 12 according to the signal strength and direction corresponding to the response signal of each wireless identification card, and The estimated distance and the sub-area scanned or the scanning angle when each wireless identification card is sensed determine the sub-area (ie the identification card position) where each wireless identification card is located.
步驟S14:控制裝置13(如第一控制單元111、第二控制單元121或第三控制單元151)經由比對模組23判斷是否任一物體影像的影像位置與任一無線識別證的識別證位置相符(如位於相同子區域或影像位置與識別證位置之間的距離小於臨界距離)。Step S14: The control device 13 (such as the first control unit 111, the second control unit 121, or the third control unit 151) determines whether the image position of any object image and the identification card of any wireless identification card via the comparison module 23. The positions are consistent (for example, they are located in the same sub-area or the distance between the image position and the ID position is less than the critical distance).
若控制裝置13判斷任一物體影像的影像位置與任一無線識別證的識別證位置相符,則執行步驟S15。If the control device 13 determines that the image position of any object image matches the identification card position of any wireless identification card, step S15 is executed.
若控制裝置13判斷任一物體影像的影像位置與所有無線識別證的識別證位置皆不符,則執行步驟S16。If the control device 13 determines that the image positions of any object images do not match the identification positions of all wireless identification cards, step S16 is performed.
步驟S15:控制裝置13(如第一控制單元111、第二控制單元121或第三控制單元151)經由連結模組24對位置相符的物體影像及身分資料進行連結,並可進一步將連結後的物體影像及身分資料儲存於資料庫141(資料庫141可儲存於第一儲存單元112、第二儲存單元122或第三儲存單元152)。Step S15: The control device 13 (such as the first control unit 111, the second control unit 121, or the third control unit 151) connects the position-matched object images and identity data through the connection module 24, and further connects the connected Object images and identity data are stored in the database 141 (the database 141 may be stored in the first storage unit 112, the second storage unit 122, or the third storage unit 152).
於一實施例中,控制裝置13先依據身分資料於資料庫141中查詢對應的物體影像(如先前與相同身分資料連結並儲存於資料庫141的同一物體的其他物體影像或物體於註冊時所登錄的物體影像),並於判斷所查詢的物體影像與所拍攝的物體影像相符(即為同一物體)時才對位置相符的物體影像及身分資料進行連結。藉此,本發明可有效確保所連結的物體影像及身分資料正確,而可提升辨識精確度。In an embodiment, the control device 13 first searches the database 141 for the corresponding object image according to the identity data (such as other object images or objects of the same object previously linked to the same identity data and stored in the database 141 during registration). Registered object image), and only when it is determined that the queried object image matches the captured object image (that is, the same object), the position-matched object image and identity data are linked. Therefore, the present invention can effectively ensure that the linked object image and identity data are correct, and can improve the recognition accuracy.

The control device 13 can determine the query object image and the captured object image. In case of discrepancy, a warning is issued via the aforementioned man-machine interface. Therefore, the present invention can effectively detect whether an object in the surveillance area is using a wireless identification card.
步驟S16:控制裝置13(如第一控制單元111、第二控制單元121或第三控制單元151)經由不明物體偵測模組25判定物體影像為不明物體。Step S16: The control device 13 (such as the first control unit 111, the second control unit 121, or the third control unit 151) determines that the image of the object is an unknown object via the unknown object detection module 25.
於一實施例中,控制裝置13可進一步經由人機介面發出警示,以提示管理員監視區域存在身分不明物體。藉此,當身分不明物體尾隨身分合法物體進入監視區域時可被本發明有效偵測出。In an embodiment, the control device 13 may further issue a warning via a human-machine interface to remind the administrator that an unknown object exists in the surveillance area. Thereby, when the unknown object trails the legal object entering the surveillance area, it can be effectively detected by the present invention.

步驟S21:主機15的第三控制單元151(即控制單元13)依據各物體的物體影像查詢儲存於第三儲存單元152的資料庫141,以判斷是否任一物體影像屬於已知的物體(如先前已連結或已註冊的物體)的物體影像。Step S21: The third control unit 151 (ie, the control unit 13) of the host 15 queries the database 141 stored in the third storage unit 152 according to the object image of each object to determine whether any object image belongs to a known object (such as Image of an object that was previously linked or registered).
若第三控制單元151判斷任一物體影像屬於已知的物體(如資料庫141中存在相符且已連結特定身分資料的物體影像),則可直接確認此物體的身分。否則,第三控制單元151執行步驟S23。If the third control unit 151 determines that any object image belongs to a known object (for example, there is a matching object image in the database 141 that has been linked with specific identity data), it can directly confirm the identity of the object. Otherwise, the third control unit 151 executes step S23.
於一實施例中,第三控制單元151還可進一步比對自資料庫141所獲得的身分資料是否與相同位置的無線識別證的身分資料是否相符,以判斷是否發生冒用無線識別證的情況。In an embodiment, the third control unit 151 can further compare whether the identity data obtained from the database 141 matches the identity data of the wireless identification card at the same location to determine whether a fraudulent use of the wireless identification card occurs. .

若第三控制單元151判斷物體影像的數量與無線識別證的數量是否皆為1,則表示不需對物體與無線識別證進行定位即可直接配對,並執行步驟S27。否則,第三控制單元151執行步驟S24與步驟S25以對各物體影像及各無線識別證進行定位。If the third control unit 151 determines whether the number of object images and the number of wireless identification cards are both 1, it means that the object and the wireless identification card can be directly paired without performing positioning, and step S27 is performed. Otherwise, the third control unit 151 executes steps S24 and S25 to locate each object image and each wireless identification card.
步驟S24:第三控制單元151(即控制裝置13)經由影像定位模組21決定各物體影像於監視區域中的影像位置。Step S24: The third control unit 151 (ie, the control device 13) determines the image position of each object image in the monitoring area via the image positioning module 21.
主機15於執行步驟S24期間,還可同時執行步驟S25。步驟S25:主機15的第三控制單元151自第三儲存單元152 (即儲存裝置14)取得查找表140,並依據各無線識別證的回應訊號的訊號強度及感應到各無線識別證時使用的掃描設定決定各無線識別證所在的子區域(即識別證位置)。During execution of step S24, the host 15 may also execute step S25 at the same time. Step S25: The third control unit 151 of the host 15 obtains the lookup table 140 from the third storage unit 152 (that is, the storage device 14), and according to the signal strength of the response signal of each wireless identification card and the signal used when sensing each wireless identification card The scan setting determines the sub-area (ie, the ID position) where each wireless ID is located.
步驟S26:第三控制單元151經由比對模組23判斷是否任一物體影像的影像位置與任一無線識別證的識別證位置相符。Step S26: The third control unit 151 determines whether the image position of any object image matches the identification card position of any wireless identification card via the comparison module 23.
若第三控制單元151判斷任一物體影像的影像位置與任一無線識別證的識別證位置相符,則執行步驟S27。If the third control unit 151 determines that the image position of any object image matches the identification card position of any wireless identification card, step S27 is performed.
若第三控制單元151判斷任一物體影像的影像位置與所有無線識別證的識別證位置皆不符,則執行步驟S28。If the third control unit 151 determines that the image positions of any object images do not match the identification positions of all wireless identification cards, step S28 is performed.

FIG. 6 is a partial flowchart of a method for automatically identifying an object according to a third embodiment of the present invention. In this embodiment, the monitoring area is planned as a plurality of sub-areas. The scanning device 12 is a phase array scanning device (as shown in FIG. 3), and can selectively perform a single scan on a part of sub-regions (such as a single sub-region or a sub-region at the same angle).
並且,掃描裝置12儲存有多組掃描設定,各掃描設定分別對應部分子區域。當掃描裝置12依據任一掃描設定進行掃描時可感應對應的子區域中的無線識別證。In addition, the scanning device 12 stores a plurality of sets of scanning settings, and each scanning setting corresponds to a partial sub-area. When the scanning device 12 scans according to any scanning setting, it can sense the wireless identification card in the corresponding sub-area.
相較於圖5所示的辨識方法,本實施例的辨識方法的步驟S22包括以下步驟。Compared to the identification method shown in FIG. 5, step S22 of the identification method of this embodiment includes the following steps.

步驟S31:第二控制單元121對所選擇的子區域進行感應。於一實施例中,第二控制單元121依據所選擇的掃描設定控制相位陣列天線模組30及波束控制模組31朝特定角度或特定的子區域發射掃描波束。Step S31: The second control unit 121 senses the selected sub-area. In an embodiment, the second control unit 121 controls the phase array antenna module 30 and the beam control module 31 to transmit a scanning beam toward a specific angle or a specific sub-region according to the selected scanning setting.
並且,當位於前述角度或子區域的無線識別證收到掃描波束後,可響應掃描波束而回傳包括身分資料的回應訊號(第二回應訊號)。In addition, after the wireless identification card located at the foregoing angle or sub-area receives the scanning beam, it may return a response signal (second response signal) including identity data in response to the scanning beam.
步驟S32:第二控制單元121判斷是否自任一無線識別證收到回應訊號。Step S32: The second control unit 121 determines whether a response signal is received from any wireless identification card.
若第二控制單元121判斷收到回應訊號,則執行步驟S33。否則,執行步驟S34。If the second control unit 121 determines that a response signal is received, step S33 is performed. Otherwise, step S34 is executed.
步驟S33:第二控制單元121依據所收到的回應訊號記錄無線識別證所對應的訊號強度或掃描設定(即當前所使用的掃描設定)。Step S33: The second control unit 121 records the signal strength or scanning setting (ie, the currently used scanning setting) corresponding to the wireless identification card according to the received response signal.
於一實施例中,無線識別證於收到步驟S31中發出的掃描訊號後可計算所收到的掃描訊號的訊號強度,將算出的訊號強度加入至回應訊號,並回傳回應訊號至掃描裝置12。In one embodiment, after receiving the scanning signal sent in step S31, the wireless identification card can calculate the signal strength of the received scanning signal, add the calculated signal strength to the response signal, and return the response signal to the scanning device. 12.
步驟S34:第二控制單元121判斷是否所有子區域皆完成掃描(如判斷是否所有掃描設定皆已被選擇使用)。Step S34: The second control unit 121 determines whether all sub-areas have been scanned (for example, whether all scanning settings have been selected for use).
若第二控制單元121判斷所有子區域皆完成掃描,則執行步驟S35。否則,第二控制單元121再次執行步驟S30以選擇另一子區域(如選擇另一掃描設定)來繼續進行掃描。If the second control unit 121 determines that all the sub-areas have been scanned, step S35 is performed. Otherwise, the second control unit 121 performs step S30 again to select another sub-area (such as selecting another scan setting) to continue scanning.
步驟S35:第二控制單元121選擇同一無線識別證所回傳的多個回應訊號(各回應訊號是分別於對不同的子區域或角度進行感應時所收到)的其中之一(如選擇訊號強度最強的回應訊號)。接著執行步驟S23。Step S35: The second control unit 121 selects one of the multiple response signals returned by the same wireless identification card (each response signal is received when sensing different sub-areas or angles respectively) (such as selecting a signal The strongest response signal). Then step S23 is executed.
值得一提的是,於本實施例中,查找表140是記錄各掃描設定、不同的訊號強度(範圍)與各子區域之間的對應關係。步驟S25是依據所選擇的回應訊號所對應的訊號強度與所使用的掃描設定來進行查表,以獲得對應的子區域(即識別證位置)。It is worth mentioning that, in this embodiment, the lookup table 140 records the corresponding relationship between each scan setting, different signal strength (range), and each sub-region. Step S25 is to perform a table lookup according to the signal strength corresponding to the selected response signal and the scanning settings used to obtain the corresponding sub-area (ie the identification card position).
本發明經由相位陣列掃描裝置,可有效對無線識別證進行定位。並且,本發明經由使用相位陣列掃描裝置,可於僅設置單一掃描裝置的情況下,對無線識別證先進行定位,而可降低系統設置成本與占用空間。The invention can effectively locate the wireless identification card through the phase array scanning device. In addition, by using a phase array scanning device, the present invention can locate the wireless identification card in the case where only a single scanning device is provided, thereby reducing the system installation cost and the occupied space.
續請同時參閱圖5、圖6及圖7,圖7為本發明第四實施例的自動辨識物體身分的方法的部分流程圖。相較於圖6所示的辨識方法,本實施例的辨識方法可進一步對單一無線識別證進行掃描以降低干擾並提升定位精確度。本實施例的辨識方法的步驟S22包括以下步驟。Continue to refer to FIG. 5, FIG. 6, and FIG. 7 at the same time. FIG. 7 is a partial flowchart of a method for automatically identifying the identity of an object according to a fourth embodiment of the present invention. Compared with the identification method shown in FIG. 6, the identification method of this embodiment can further scan a single wireless identification card to reduce interference and improve positioning accuracy. Step S22 of the identification method of this embodiment includes the following steps.
步驟S40:掃描裝置12的第二控制單元121對監視區域的所有子區域進行第一次掃描以接收位於監視區域中的所有無線識別證的回應訊號(第一回應訊號),並分析第一回應訊號來取得所有無線識別證的身分資料及數量。接著,第二控制單元121選擇所感測到的多個無線識別證的其中之一(如選擇對應的身分資料),並產生對應的掃描訊號(此掃描訊號僅會使所選擇無線識別證對第二次掃描進行回應)。Step S40: The second control unit 121 of the scanning device 12 scans all sub-areas of the surveillance area for the first time to receive response signals (first response signals) of all wireless identification cards located in the surveillance area, and analyzes the first response Signal to get the identity information and quantity of all wireless identification cards. Next, the second control unit 121 selects one of the plurality of wireless identification cards (such as selecting corresponding identity data) and generates a corresponding scanning signal (this scanning signal only causes the selected wireless identification card to Two scans in response).
接著,第二控制單元121依據此掃描訊號執行步驟S41-S46來對各子區域進行第二次掃描,以接收所選擇的無線識別證的一或多個回應訊號(第二回應訊號)。並且,當第二控制單元121收到所選擇的無線識別證的多個回應訊號時,可選擇訊號強度最強的回應訊號來進行後續處理。Then, the second control unit 121 performs steps S41-S46 according to the scan signal to perform a second scan on each sub-region to receive one or more response signals (second response signals) of the selected wireless identification card. In addition, when the second control unit 121 receives multiple response signals of the selected wireless identification card, it may select a response signal with the strongest signal strength for subsequent processing.
圖7的步驟S41-S46是分別與圖6的步驟S30-S35相同或相似,其細節於此不再贅述。接著執行步驟S47。Steps S41-S46 of FIG. 7 are the same as or similar to steps S30-S35 of FIG. 6, respectively, and details thereof will not be repeated here. Then, step S47 is executed.
步驟S47:第二控制單元121判斷是否所有無線識別證皆完成掃描(如判斷是否以針對所有身分資料進行掃描)。Step S47: The second control unit 121 determines whether all the wireless identification cards have been scanned (such as determining whether to scan for all identity data).
若第二控制單元121判斷所有無線識別證皆完成掃描,則執行步驟S23。否則,第二控制單元121再次執行步驟S40以選擇另一無線識別證(即選擇另一身分資料)來繼續進行掃描。If the second control unit 121 determines that all the wireless identification cards have been scanned, step S23 is performed. Otherwise, the second control unit 121 executes step S40 again to select another wireless identification card (ie, select another identity data) to continue scanning.
本發明經由針對單一無線識別證進行掃描,可有效降低無線射頻干擾,進而提升掃描精確度。By scanning a single wireless identification card, the present invention can effectively reduce wireless radio frequency interference, thereby improving scanning accuracy.
續請同時參閱圖8A至圖8D,圖8A為本發明一實施例的自動辨識物體身分的第一示意圖,圖8B為本發明一實施例的自動辨識物體身分的第二示意圖,圖8C為本發明一實施例的自動辨識物體身分的第三示意圖,圖8D為本發明一實施例的自動辨識物體身分的第四示意圖。Continue to refer to FIGS. 8A to 8D at the same time. FIG. 8A is a first schematic diagram of automatically identifying the identity of an object according to an embodiment of the present invention, FIG. 8B is a second schematic diagram of automatically identifying the identity of an object according to an embodiment of the present invention, and FIG. A third schematic diagram of automatically identifying the identity of an object according to an embodiment of the invention, and FIG. 8D is a fourth schematic diagram of automatically identifying the identity of an object according to an embodiment of the invention.
如圖8A所示,於本例子中,監視區域包括九個子區域41-49。辨識系統10可經由影像擷取裝置11拍攝監視影像,並於辨識後判斷子區域41有物體53,子區域44有物體51且子區域45有物體52。As shown in FIG. 8A, in this example, the surveillance area includes nine sub-areas 41-49. The recognition system 10 can capture a surveillance image through the image capturing device 11 and determine that the sub-region 41 has an object 53, the sub-region 44 has an object 51, and the sub-region 45 has an object 52 after recognition.
接著,如圖8B所示,辨識系統10可經由掃描裝置12執行第一次掃瞄並判斷監視區域中存在兩個無線識別證61、62。接著,辨識系統10先經由掃描裝置12針對無線識別證61執行第二次掃瞄。Next, as shown in FIG. 8B, the identification system 10 may perform the first scan through the scanning device 12 and determine that there are two wireless identification cards 61 and 62 in the surveillance area. Next, the identification system 10 first performs a second scan on the wireless identification card 61 via the scanning device 12.
具體而言,本例子的掃描裝置12儲存分別對應三組掃描角度V1-V3的三組掃描設定。掃描裝置12先依據第一組掃描設定朝掃描角度V1發射掃描波束,再依據第二組掃描設定朝掃描角度V2發射掃描波束,最後依據第三組掃描設定朝掃描角度V3發射掃描波束。藉此,完成第二次掃描。Specifically, the scanning device 12 of this example stores three sets of scanning settings corresponding to three sets of scanning angles V1-V3, respectively. The scanning device 12 first transmits a scanning beam toward the scanning angle V1 according to the first group of scanning settings, then transmits a scanning beam toward the scanning angle V2 according to the second group of scanning settings, and finally transmits a scanning beam toward the scanning angle V3 according to the third group of scanning settings. This completes the second scan.
並且,於第二次掃描中,僅有無線識別證61會響應掃描裝置12所發出的掃描波束來回傳回應訊號(第二回應訊號)。Moreover, in the second scan, only the wireless identification card 61 transmits a response signal (second response signal) back and forth in response to the scanning beam sent by the scanning device 12.
值得一提的是,當掃描裝置12朝掃描角度V1發射掃描波束時無線識別證61會受響應而回傳回應訊號。並且,當掃描裝置12朝掃描角度V2發射掃描波束時,掃描波束的溢波會使無線識別證61受響應而回傳另一回應訊號。對此,於本例子中的掃描裝置12於收到無線識別證61的兩組回應訊號時會選擇訊號強度最強的回應訊號(如對應掃描角度V1的回應訊號)來加以保留。It is worth mentioning that when the scanning device 12 transmits the scanning beam toward the scanning angle V1, the wireless identification card 61 will respond and return a response signal. In addition, when the scanning device 12 transmits the scanning beam toward the scanning angle V2, the overflow of the scanning beam will cause the wireless identification card 61 to respond and return another response signal. In this regard, when the scanning device 12 in this example receives the two sets of response signals of the wireless identification card 61, it selects the response signal with the strongest signal strength (such as the response signal corresponding to the scanning angle V1) to retain it.
接著,辨識系統10可依據第一組掃描設定與此回應訊號的訊號強度來進行查表以決定無線識別證61的識別證位置為子區域44。Then, the identification system 10 can perform a table lookup according to the signal strength of the first set of scan settings and the response signal to determine the identification card position of the wireless identification card 61 as the sub-region 44.
接著,如圖8C所示,辨識系統10經由掃描裝置12針對無線識別證62執行第三次掃瞄,以分別依據三組掃描設定朝掃描角度V1-V3分別發射掃描波束。Next, as shown in FIG. 8C, the recognition system 10 performs a third scan on the wireless identification card 62 via the scanning device 12 to respectively emit scanning beams toward the scanning angles V1-V3 according to the three sets of scanning settings.
並且,於第三次掃描中,僅有無線識別證62會響應掃描裝置12所發出的掃描波束來回傳回應訊號(第二回應訊號)。And, in the third scan, only the wireless identification card 62 will transmit a response signal (second response signal) back and forth in response to the scanning beam sent by the scanning device 12.
並且,掃描裝置12於收到無線識別證62的多組回應訊號時會選擇訊號強度最強的回應訊號(如對應掃描角度V2的回應訊號)來加以保留。In addition, when receiving multiple sets of response signals from the wireless identification card 62, the scanning device 12 selects a response signal with the strongest signal strength (such as a response signal corresponding to the scanning angle V2) to retain it.
接著,辨識系統10可依據第二組掃描設定與此回應訊號的訊號強度來進行查表以決定無線識別證62的識別證位置為子區域45。Then, the identification system 10 may perform a table lookup according to the signal strength of the second set of scanning settings and the response signal to determine the identification card position of the wireless identification card 62 as the sub-region 45.
接著,如圖8D所示,辨識系統10可將位於相同子區域的物體51與無線識別證61進行配對,並將位於相同子區域的物體52與無線識別證62進行配對。Next, as shown in FIG. 8D, the recognition system 10 may pair the object 51 located in the same sub-area with the wireless identification card 61, and pair the object 52 located in the same sub-area with the wireless identification card 62.
並且,辨識系統10可對未與任何無線識別證配對成功的物體53進行標記並經由人機介面提示管理員發現身分不明物體53。藉此,本發明可準確執行物體身分辨識。In addition, the identification system 10 can mark the objects 53 that have not been successfully paired with any wireless identification card, and prompt the administrator to find the unknown objects 53 through the human-machine interface. Accordingly, the present invention can accurately perform object identification.
當然,本發明還可有其它多種實施例,在不悖離本發明精神及其實質的情況下,本發明所屬技術領域中具有通常知識者當可根據本發明作出各種相應的改變和變形,但這些相應的改變和變形都應屬於本發明的範圍。Of course, the present invention may have other various embodiments.
