Description
本発明は、顔認証照合技術を応用し、ＩＣタグの活用により、物品販売店舗における陳列商品の万引き検知に寄与できる顔認証応用万引き検知システムに関する。 The present invention relates to a face authentication application shoplifting detection system that can contribute to shoplifting detection of displayed products in an article sales store by applying face authentication verification technology and utilizing an IC tag.
最近の物品販売小売業者は、拡大する「万引き被害」に悩まされている。その被害額は業種によるばらつきはあるものの、平均的には該当店舗総売上額の１〜２％と見られている。この額は対利益比に置き換えると極めて大きな額となり、この被害により廃業を余儀なくされるケースも昨今多く見られる。
最近は、店舗セキュリティーに関する監視機器等も様々なものが販売され
普及しつつあるが、特効薬に該当するものは見当たらない。監視カメラ等がもっとも普及している品目であるが、人的監視が主体である限りおのずと限界がある。またＩＣタグも徐々に普及しつつあり、個別商品対応では、現時点では自鳴式ＩＣタグが一般的となりつつある、これは商品にこのタグを取付けておき顧客がレジを経由せず店舗ゲートを通過すると、タグ自身から大音響を発する仕組みである。この場合、このような処置をしても、タグを引きちぎり、そのまま逃げ去るケースもあり、確実な対策とはいえないのが実情である。
Recent merchandise retailers are plagued by the growing “shoplifting damage”. Although the amount of damage varies depending on the type of industry, it is estimated to be 1-2% of the total sales of the store on average. This amount is extremely large when it is replaced with the ratio of profits, and there are many cases in which these businesses are forced to close their businesses due to this damage.
Recently, various monitoring devices related to store security have been sold and spread, but there are no specific drugs that can be used. Surveillance cameras, etc. are the most popular items, but they have their own limitations as long as they are mainly human surveillance. In addition, IC tags are gradually spreading, and for individual products, at present, self-sounding IC tags are becoming popular. This is because the customer attaches this tag to the product and the customer goes to the store gate without going through the cash register. When it passes, it is a mechanism that emits a loud sound from the tag itself. In this case, even if such a measure is taken, there is a case where the tag is torn off and escaped as it is, which is not a reliable measure.
このような背景において発案されたのが本発明である。万引きは、常習犯が多く、同一店舗で繰り返し犯行に及ぶケースも多くあり、万引き現行犯検知と同様に再犯を防止することも極めて重要なポイントである。本発明は、公知の顔認証照合機能を応用し、店舗内での顧客購買行動に関わるＩＣタグ信号を起点とした顧客映像と退店間際の顧客画像をリアルタイムに顔認証照合し、万引き検知を行うものである、撮影画像、映像の撮影顔角度等の影響により万一自動顔認証照合に失敗した場合でも、記録映像に基づき、閉店後の人為操作により容易に万引き犯の特定が可能である。この結果をデータベースに蓄積しておき、それ以降の来店顧客顔画像とのリアルタイムな顔認証照合により、再犯の可能性の芽を摘むことは可能である。 The present invention was conceived in such a background. Shoplifting has many regular offenses and many cases of repeated offenses at the same store, and it is extremely important to prevent re-offending as well as detection of shoplifting current offenders. The present invention applies a known face authentication collation function, and performs face authentication collation in real time between a customer image starting from an IC tag signal related to customer purchase behavior in a store and a customer image just before leaving the store, and detects shoplifting. Even if automatic face authentication verification fails due to the effects of the captured image, the shooting face angle of the video, etc., it is possible to easily identify shoplifters by manual operation after closing based on the recorded video. . It is possible to accumulate the results in a database and find out the possibility of re-offending by real-time face verification collation with customer visitor face images thereafter.
これまで、万引き防止に関しては、陳列台に置かれていることが前提であるモニター商品に発信器を取付け、該当商品が受信器設置陳列台を一定距離離れた段階で、発信器信号受信断にて万引きであると判断し、ブザーが吹鳴する。また店舗出口付近ゲートが、商品からの発信信号を受信し、該当顧客に対しカメラ撮影がなされる装置が知られている（例えば、特許文献１参照。）。 Until now, with regard to shoplifting prevention, a transmitter is attached to a monitor product that is assumed to be placed on a display stand, and the transmitter signal is cut off when the product is separated from the receiver installation display stand by a certain distance. Judging from shoplifting, the buzzer sounds. In addition, a device is known in which a gate near a store exit receives a transmission signal from a product, and a camera is photographed for a corresponding customer (see, for example, Patent Document 1).
本発明は、店舗内での顧客購買行動をカメラ撮影し、この映像を基に、顔認証照合により万引き犯を特定するものであり、具体的には該当商品を陳列台から取上げ、陳列台に戻さなかった顧客は、その後の店舗内行動として万引き犯としてレジを経由せずに商品を持逃げするか、もしくはレジ精算をおこなうかいずれかの行動予定しかないという判断基準に基づくものである。ＩＣタグの活用により、ＩＣタグとＩＣタグ情報読取器との交信信号の断時点、即ち商品が陳列台を離れた時点にてカメラ撮影を開始し、その後商品が陳列台に戻れば、該当撮影映像は保存されない、つまり顧客が商品を品評する毎に映像を更新していけば、陳列台に商品を戻さず、映像が保存されている顧客映像が、既述顧客（万引き犯かもしくは正規購入予定者）に該当することになり、密かに確実に万引き犯の特定が可能であり、また犯人の画像をデータベースに登録しておけば、高確率で再犯防止が可能である。 The present invention captures customer purchase behavior in a store with a camera, and based on this video, identifies a shoplifter by face authentication verification. Specifically, the product is picked up from the display stand and displayed on the display stand. The customer who has not returned is based on a judgment criterion that the subsequent behavior in the store has only an action plan to either carry away the merchandise without going through the cash register as a shoplifter or to perform checkout settlement. By using the IC tag, the camera shooting starts when the communication signal between the IC tag and the IC tag information reader is interrupted, that is, when the product leaves the display stand. If the video is not saved, that is, if the customer updates the video every time the product is reviewed, the product video is not returned to the display stand, and the customer video on which the video is saved is a shoplifter or a regular purchase. The shoplifter can be identified secretly and surely, and if the image of the offender is registered in the database, it is possible to prevent recidivism with a high probability.
つまり、背景技術においては、該当商品が陳列台を一定距離はなれた時点で万引き犯として特定しているが、モニター商品でない一般商品の場合は、その時点での万引き犯特定は間違いであり、店舗内でブザーを吹鳴させることは、店舗環境・雰囲気維持の観点から好まれない。また背景技術では、商品取付け発信器が破壊された場合、ブザーは吹鳴するが、出口ゲートでのカメラ撮影は起動されずこの背景技術の目標は達成できない。本発明の場合は、ＩＣタグが万引き犯により破壊された場合でも、証拠映像は確実に残り、それ以後の犯人特定にはＩＣタグは一切関わらず、顔認証照合のみによるものであり、それら不測の事態にも対処可能である。また背景技術では、カメラにより該当人物を撮影し、手持ちの商品と盗まれた商品を目視照合するが、万引き犯が商品を露出させて店舗外に持ち出すことは常識的ではなく、その効果は極めて疑わしいものと考える。本発明の場合、顧客の店舗内購買行動、
品定め行動を記録した映像をベースに退店間際の顧客画像と顔認証照合し、犯人を特定するものであり、該当商品ではなく人物を特定するところがポイントである。
本発明では、顔認証照合機能とＩＣタグの活用により実効性に配慮した顔認証応用万引き検知システムを提供することを目的とする。
In other words, in the background technology, when the product concerned is a shoplifter when the display stand is separated from the display stand by a certain distance, in the case of a general product that is not a monitor product, the shoplifter identification at that point is wrong, and the store Buzzing a buzzer inside is not preferred from the standpoint of store environment and atmosphere maintenance. Also, in the background art, when the product mounting transmitter is destroyed, the buzzer sounds, but the camera shooting at the exit gate is not activated and the background art goal cannot be achieved. In the case of the present invention, even when the IC tag is destroyed by a shoplifter, the evidence video remains reliably, and the subsequent identification of the culprit is based on face verification only, regardless of the IC tag. It is possible to cope with this situation. In the background technology, the person is photographed with a camera, and the product on hand and the stolen product are visually checked. However, it is not common sense that shoplifters expose the product and take it out of the store. Think suspicious. In the case of the present invention, the customer's in-store purchase behavior,
The point is to identify the criminal, not the corresponding product, by identifying the criminal by performing face authentication against the customer image just before leaving the store based on the video recording the product-determining behavior.
It is an object of the present invention to provide a face authentication application shoplifting detection system that takes into consideration effectiveness by utilizing a face authentication collation function and an IC tag.

（顔認証応用万引き検知システム構成）
次に、顔認証応用万引き検知システム構成に就き、図５を基に説明する。入店者撮影カメラ１０１、退店者撮影カメラ１０２は該当店舗営業時間中、常時作動しており、人物を認識すると、それらを映像として撮影し、その結果を入店顧客画像ファイル部５０６、店舗内滞留顧客画像ファイル部５１４、退店顧客画像ファイル部５０７に各々記録する。次に、店舗内撮影カメラ５０３は、店舗内顧客の陳列商品品評（品定め）行動に伴い、作動、撮影し、その結果を顧客品評現場映像ファイル部５１０に記録する。既述カメラの制御は、総て監視カメラ操作部５０９により為される。
(Face authentication application shoplifting detection system configuration)
Next, the face authentication applied shoplifting detection system configuration will be described with reference to FIG. The store entrance camera 101 and the store exit camera 102 are always in operation during the corresponding store business hours. When a person is recognized, they are photographed as images, and the results are input to the store customer image file unit 506 and the store. It records in the staying customer image file part 514 and the exit customer image file part 507, respectively. Next, the in-store shooting camera 503 operates and shoots in accordance with the in-store customer display merchandise review (article determination) behavior, and records the result in the customer review site video file unit 510. The above-described cameras are all controlled by the monitoring camera operation unit 509.
ＩＣタグ情報読取器アンテナ５０５からの複数交信信号は、総てＩＣタグ交信部５０８にて管理される。ＩＣタグとの交信信号は、万引き検知処理において極めて重要であり本システムの中枢要素である。通常商品が該当陳列台に置かれた状態では、商品取付けＩＣタグと陳列台設置ＩＣタグ情報読取器アンテナとの距離は至近であり、交信は常に成立している。この状態で顧客が品評の目的で該当商品を取上げ、商品が陳列台から離れると、その距離に関わり、交信は断たれることになる。
つまり、顧客が商品と接触し、何らかの購買行動を起こすことにより、ＩＣタグと同読取器アンテナ間では、定常的に交信通断（ＯＮ／ＯＦＦ）状態が繰り返し起こっていることになる。
A plurality of communication signals from the IC tag information reader antenna 505 are all managed by the IC tag communication unit 508. The communication signal with the IC tag is extremely important in the shoplifting detection process and is a central element of the system. In a state where the normal product is placed on the display stand, the distance between the product mounting IC tag and the display stand setting IC tag information reader antenna is close, and communication is always established. In this state, when the customer picks up the corresponding product for the purpose of review and the product leaves the display stand, the communication is cut off in relation to the distance.
In other words, when the customer comes into contact with the product and initiates some purchasing behavior, the communication communication disconnection (ON / OFF) state is constantly occurring between the IC tag and the reader antenna.
万引き検知処理においてＩＣタグとの交信信号は極めて重要な役割を担っている。既述の如く店舗内顧客が品評（品定め）を行うことにより交信信号は通断を繰り返す、幾度かこの状態が継続し、顧客が商品を最後に陳列台から取上げ（交信信号断の時点）再び商品を陳列台に戻さない時間が継続した場合、その後の顧客行動としては、その商品をレジに持込み精算する、もしくは、精算せずに店舗外に持出す（即ち万引きに相当）、この２ケースしか行動パターンは存在しない。従って、最後に商品を陳列台から取上げた（交信信号断の時点）時点の映像のみを記録しておけば、万引き犯もしくは、商品購入者いずれかの行為を記録したことになる。この撮影は、顧客が入れ替わっても同様に繰り返され該当陳列台位置相当の顧客品評現場映像ファイル部５１０には常に最新情報が記録される。 In the shoplifting detection process, the communication signal with the IC tag plays an extremely important role. As described above, the customer's in-store review (determination) makes the communication signal repeatedly interrupted. This state continues several times, and the customer finally picks up the product from the display stand (when the communication signal is lost) again. If the time when the product is not returned to the display stand continues, the following customer behaviors are to bring the product to the cashier and pay it out or take it out of the store without paying it (ie equivalent to shoplifting). However, there is no behavior pattern. Therefore, if only the video at the time when the product was last picked up from the display stand (at the time of communication signal disconnection) is recorded, the act of either the shoplifter or the product purchaser is recorded. This photographing is repeated in the same manner even when the customer is switched, and the latest information is always recorded in the customer product review site video file section 510 corresponding to the corresponding display stand position.
次に、顔認証照合に関する要素に就き説明する。まず、入店顧客に関しては、以下の要素が存在する。 Next, elements relating to face authentication verification will be described. First, the following elements exist for customers who enter the store.
