- the unmanned vending machine based on video images is more powerful than the unmanned vending machine based on pure gravity and RFID (Radio Frequency Identification), because of its wider selection space and better user experience. More and more attention.
- the gravity-based unmanned vending machine has the pain point that it cannot monitor the user's shopping process.
- the image-based unmanned vending machine needs to overcome the high-risk behaviors such as blocking the camera, placing dangerous goods, and covering the theft of goods with both hands. Will cause higher risks and higher cargo damage.
- the related unmanned vending machine risk control mainly includes two conventional solutions: video image and gravity:
- the risk control solution based on video images cannot provide effective real-time early warning. Only when the unmanned vending machine operation and maintenance personnel finds that the merchandise in the vending machine is abnormal (there are abnormal items) or the product is lost during verification, it can detect the risk. All videos need to be played back manually. In addition, the above solution first needs to save all the videos and occupy a lot of storage space of the unmanned vending machine. If the video is returned to the cloud through the network, it will occupy a lot of network bandwidth and the operation and maintenance cost will increase dramatically. At the same time, manually tracing video will increase labor costs and reduce work efficiency. The behavior recognition algorithm based on pure vision is not accurate enough at present.
- the gravity sensor can monitor the weight of the goods taken or returned at any time, so as to realize the deduction.
- the unmanned vending machine cannot promptly warn in time, resulting in high cargo damage and high risk.
- there is no image monitoring function when it is found that there are abnormal goods in the unmanned vending machine, it cannot be traced back, and it cannot be located when and who has stolen the goods or placed dangerous goods.
- abnormal behavior can be discovered based on the results of image analysis, and abnormal image reporting can be triggered in time when an abnormal situation is discovered.
- the burden of data transmission is reduced, and manual interpretation and backtracking are reduced by orders of magnitude.
- it can also improve the efficiency of abnormal situation detection, in addition, it can also reduce the probability of missed judgment and improve the safety of sales.
- step 301 it is determined that the goods are taken out and sold according to the image or gravity detection.
- each cargo may be configured with a unique identification, such as an RFID identification.
- a unique identification such as an RFID identification.
- step 303 is triggered to be executed.
- step 303 the identification of the returned goods is collected, and it is determined whether it matches the identification of the removed goods. If the two match, go to step 305; if the two do not match, go to step 304.
- step 304 the current time is buffered, or the collected image of the sales process is intercepted as a high-risk image.
- step 305 it is determined whether the user has performed an abnormal operation on the goods.
- the abnormal operation may include one or more of destroying the outer packaging of the goods, adding substances to the inside of the goods, taking substances from the goods, or returning from the camera detection area after the user holds the goods. If it is determined that the user makes an abnormal operation, step 304 is executed. If it is determined that the user has not performed an abnormal operation, step 306 is executed.
- step 306 it is determined that the user returns the item normally, and the logo is deleted.

- step 402 the user identity information is uploaded to the platform to determine whether the user is a restricted user. If it is determined to be a restricted user, step 403 is performed; if it is determined to be a normal user, step 404 is performed.
- step 403 refusal to trigger the vending machine to open the door.
- step 404 the vending machine is triggered to open the door.
- step 405 it is determined that a high-risk image was generated during the shopping process.
- the method shown in the embodiments shown in FIGS. 2 and 3 may be used to determine whether to generate a high-risk image.
- the high-risk image may be cached first for subsequent reporting. If it is determined that the high-risk image is generated (cached), step 406 is executed.
- the high-risk image is reported to the server.
- some frames may be extracted from the generated high-risk image first, and only the extracted image frames are reported, thereby reducing the data transmission burden.
- step 407 the server issues an alarm so that the staff can manually identify it, or use a further image recognition method to interpret the high-risk image.
- step 408 it is determined whether the user performs a violation operation based on the high-risk image. If it is determined that the user has performed the violation operation, step 409 is performed; if it is determined that the user has not performed the violation operation, it is considered that a misjudgment has occurred, and step 412 is performed.
- step 409 it is determined whether the statistical value of the user's illegal operation has reached a predetermined threshold. If the predetermined threshold has been reached, step 411 is performed; if the predetermined threshold has not been reached, step 410 is performed.
- the recorded user violation operation statistical value is increased.
- the amount of increased statistical value may also be determined according to the type of the user's current violation operation, such as a common violation operation plus 1, a malicious violation manipulation plus 10, and so on.
- step 411 the user right is modified to restrict the user.
- step 412 the image analysis training data set is updated with high-risk images.
- the image features and the image analysis model are updated according to the updated image analysis training data set, and sent to the vending machine to update the local image features and the image analysis model.

本公开的售货机控制方法的一些实施例的流程图如图1所示。在售货机开门的状态下开始执行如下操作:A flowchart of some embodiments of the vending machine control method of the present disclosure is shown in FIG. 1. Start the following operations when the vending machine is open:
在步骤101中,售货机在用户的触发下开门。在一些实施例中,用户可以通过扫描售货机二维码,或通过其他方式告知售货机自身的身份以触发售货机开门。In step 101, the vending machine opens the door under the user's trigger. In some embodiments, the user can trigger the vending machine to open the door by scanning the QR code of the vending machine, or informing the identity of the vending machine by other means.
当用户触发开门后,售货机通过图像采集设备采集售货机有效范围内的图像。在一些实施例中,有效范围可以包括售货机的正前方,售货机的里面,以及开门之后门与售货机之间的区域中的一种或多种。在一些实施例中,售货机包括2路以上图像采集设备,可以采集异常和非异常的图像且均缓存,还可以缓存存在异常图像的时刻的未异常的图像,从而保证缓存的高风险图像的质量。在一些实施例中,可以采用5路摄像头,分别位于左、右、上、下侧探测货架,以及由货架内向外探测前方。After the user triggers the door opening, the vending machine collects images within the effective range of the vending machine through the image acquisition device. In some embodiments, the effective range may include one or more of the area directly in front of the vending machine, inside the vending machine, and the area between the door and the vending machine after the door is opened. In some embodiments, the vending machine includes more than two image acquisition devices, which can collect abnormal and non-abnormal images and cache them, and can also cache non-abnormal images at the time of abnormal images, so as to ensure the cache of high-risk images quality. In some embodiments, a five-channel camera may be used, which is located on the left, right, upper, and lower sides to detect the shelf, and to detect the front from the inside to the outside.
在步骤102中,通过图像分析算法判断采集的图像是否异常。在一些实施例中,图像异常可以利用图像分析算法确定。在一些实施例中,图像异常可以指的是一个或多个图像采集设备(如摄像头)被遮挡。若确定采集的图像异常,则执行步骤103。In step 102, an image analysis algorithm is used to determine whether the collected image is abnormal. In some embodiments, the image abnormality can be determined using an image analysis algorithm. In some embodiments, image abnormality may refer to one or more image acquisition devices (such as cameras) being blocked. If it is determined that the collected image is abnormal, step 103 is performed.
在一些实施例中,可以基于设定的图像异常情况分析出现图像异常的可能性,当可能性超过预定异常阈值时确定图像异常。In some embodiments, the possibility of occurrence of an image abnormality may be analyzed based on the set image abnormality, and the image abnormality is determined when the probability exceeds a predetermined abnormality threshold.
在步骤103中,确定当前采集的图像为高风险图像。In step 103, it is determined that the currently acquired image is a high-risk image.
在步骤104中,将高风险图像上报售货机控制服务器,以便服务器识别用户风险行为。在一些实施例中,图像上报的操作可以在确定存在高风险图像后即时进行从而提高图像上报效率;在一些实施例中,可以在售货机关门,或售货机持续开门的时间超过预定时长时执行上报过程,降低图像上报的频率,降低通信和数据处理负担。In step 104, the high-risk image is reported to the vending machine control server, so that the server recognizes the user's risk behavior. In some embodiments, the image reporting operation may be performed immediately after it is determined that there is a high-risk image to improve the image reporting efficiency; in some embodiments, the door may be opened at the sales office, or the vending machine continues to open the door for more than a predetermined duration Perform the reporting process to reduce the frequency of image reporting and reduce the burden of communication and data processing.
通过这样的方法,能够在图像采集异常的情况下及时做出反应,将采集的图像上传给服务器供服务器解析,从而实现及时反馈图像,提高异常发现的效率,提高售货机的安全性。Through this method, it can react in time when the image collection is abnormal, and upload the collected image to the server for the server to analyze, so as to realize the timely feedback of the image, improve the efficiency of abnormal discovery, and improve the safety of the vending machine.
本公开的售货机控制方法的另一些实施例的流程图如图2所示。A flowchart of some other embodiments of the vending machine control method of the present disclosure is shown in FIG. 2.
在步骤201中,售货机在用户的触发下开门。In step 201, the vending machine opens the door under the user's trigger.
在步骤202中,对采集的图像进行图像分析,基于售货机本地存储的图像特征和图像分析模型判断采集的图像是否异常。在一些实施例中,图像异常可以为出现一个或多个摄像头被遮挡。若确定采集的图像异常,则执行步骤203。若未发现图像异常,则执行步骤204。In step 202, image analysis is performed on the collected image, and it is determined whether the collected image is abnormal based on the image characteristics and the image analysis model stored locally at the vending machine. In some embodiments, the image abnormality may be that one or more cameras are blocked. If it is determined that the collected image is abnormal, step 203 is executed. If no abnormal image is found, step 204 is executed.
在一些实施例中,图像异常可以包括多种情况,如:根据图像分析确定售货机内出现了异常物体;用户对货物做出异常操作,异常操作可以包括破坏货物外包装、向货物内部加入物质、从货物中取物质或用户持货物离开摄像头探测区域后又返回中的 一项或多项;或,货物的尺寸、颜色或透明度发生改变等。In some embodiments, the image abnormality may include a variety of situations, such as: it is determined that an abnormal object has occurred in the vending machine according to the image analysis; the user performs abnormal operations on the goods, and the abnormal operations may include destroying the outer packaging of the goods and adding substances to the inside of the goods 1. One or more items taken from the goods or the user returns the goods after leaving the camera detection area with the goods; or, the size, color or transparency of the goods changes.
在一些实施例中,可以利用售货机本地存储的图像特征和图像分析模型进行特征匹配分析,确定图像是否异常。In some embodiments, the image features and image analysis models locally stored in the vending machine may be used to perform feature matching analysis to determine whether the image is abnormal.
在步骤203中,缓存各个图像采集设备采集的图像作为高风险图像,进而执行步骤206。In step 203, the images collected by each image collection device are cached as high-risk images, and then step 206 is executed.
在步骤204中,基于摄像头采集的图像确定货物变化情况,基于重力探测确定货物变化情况。在一些实施例中,可以根据采集的图像,基于图像算法识别出***作的唯一货物,基于图像的轨迹识别出是放回还是拿出操作。根据重力探测,基于重量增加或减少判断是货物放回还是拿出。基于重量变化克数确定可能***作的货物或货物组合确定重量减少量,基于预存的各种货物的重量确定哪个或哪些货物被取出。In step 204, the change in cargo is determined based on the image collected by the camera, and the change in cargo is determined based on gravity detection. In some embodiments, the only goods to be operated can be identified based on the image algorithm based on the collected image, and whether to put back or take out the operation can be identified based on the trajectory of the image. According to gravity detection, it is judged whether the goods are put back or taken out based on the weight increase or decrease. The weight or the combination of goods that may be operated is determined based on the weight change in grams, and the weight reduction is determined, and which one or which goods are taken out is determined based on the weight of various pre-stored goods.
在步骤205中,基于图像和基于重力探测确定的货物变化情况是否一致。在一些实施例中,当根据图像轨迹判断出的动作与重力增减判断的动作不一致,或者图像识别的***作商品与重力变化克数不吻合时,说明该次操作可能出现了商品遮挡、异常置物等高风险行为;当图像识别与重力识别结果一致时,说明这是一次正常的购物流程,不缓存购物图像,将商品加入购物车或从购物车删减。In step 205, it is determined whether the cargo changes based on the image and the gravity detection are consistent. In some embodiments, when the action determined according to the image trajectory is inconsistent with the action determined by the increase or decrease of gravity, or the operated product identified by the image does not coincide with the change in gram of gravity, it may indicate that the operation has occurred product occlusion or abnormality. High-risk behaviors such as storage; when the image recognition and gravity recognition results are consistent, it is a normal shopping process. The shopping images are not cached, and the goods are added to or deleted from the shopping cart.
若变化情况一致,则执行步骤206;若变化情况不一致,则执行步骤203,采集当前时刻的图像作为高风险图像缓存。If the changes are consistent, go to step 206; if the changes are not consistent, go to step 203, and collect the image at the current moment as a high-risk image cache.
在步骤206中,判断售货机是否关门,或是否虽然开门但保持开门状态的时长超过预定第一时长。若触发售货机关门,或开门时长超过预定第一时长,则执行步骤207。In step 206, it is determined whether the vending machine closes the door, or whether the time for which the door remains open despite opening the door exceeds a predetermined first time. If the door of the sales office is triggered, or the opening time exceeds the predetermined first time, step 207 is executed.
在一些实施例中,可以只在用户关门结算时,执行步骤207。在另一些实施例中,可以在售货机通信闲时执行步骤207。In some embodiments, step 207 may be performed only when the user closes the door to settle. In other embodiments, step 207 may be performed when the vending machine is idle.
在步骤207中,判断当前缓存区是否缓存有高风险图像。若缓存有高风险图像,则执行步骤208。In step 207, it is determined whether high-risk images are cached in the current cache area. If high-risk images are cached, step 208 is executed.
在步骤208中,从缓存的高风险图像中筛选图像帧。在一些实施例中,筛选操作可以包括挑选图像清晰的,未完全被遮挡的数据帧,以及对于极为相似的数据只保留一帧或几帧等。In step 208, image frames are filtered from the cached high-risk images. In some embodiments, the filtering operation may include selecting data frames with clear images that are not completely occluded, and retaining only one frame or a few frames for very similar data.
在步骤209中,将筛选出的高风险图像帧上报售货机控制服务器,并删除缓存区缓存的高风险图像。In step 209, the filtered high-risk image frames are reported to the vending machine control server, and the high-risk images cached in the cache area are deleted.
通过这样的方法,能够通过图像是否异常,以及图像与重力探测的变化情况判读结果是否一致这两种途径判断是否触发缓存高风险图像并上报,降低了事件漏提取的 概率,提高了售货机贩卖货物的安全性;同时,也无需持续存储图像,降低了对售货机存储空间的要求。Through this method, whether the image is abnormal and whether the interpretation result of the image and the gravity detection are consistent can be judged whether the cache high-risk image is triggered and reported, which reduces the probability of missed event extraction and improves vending machine sales. The safety of the goods; at the same time, there is no need to continuously store images, reducing the storage space requirements of the vending machine.
相关技术中,基于视频图像的无人售货机相对于基于纯重力、RFID(Radio Frequency Identification,射频识别)的无人售货机,由于其具备更广阔的选品空间,更优质的用户体验,引起越来越多的关注。但是基于重力的无人售货机存在无法监控用户购物流程的痛点,基于图像的无人售货机需要克服真实场景中容易出现的遮挡摄像头、危险品放置、双手盖住商品盗窃等高风险行为,仍然会造成较高的风险及较高的货损。In the related art, the unmanned vending machine based on video images is more powerful than the unmanned vending machine based on pure gravity and RFID (Radio Frequency Identification), because of its wider selection space and better user experience. More and more attention. However, the gravity-based unmanned vending machine has the pain point that it cannot monitor the user's shopping process. The image-based unmanned vending machine needs to overcome the high-risk behaviors such as blocking the camera, placing dangerous goods, and covering the theft of goods with both hands. Will cause higher risks and higher cargo damage.
相关的无人售货机风险控制主要包含视频图像与重力两种常规解决方案:The related unmanned vending machine risk control mainly includes two conventional solutions: video image and gravity:
(1)通过布置监控摄像头持续监控顾客消费过程,当补货人员或无人售货机维护人员发现售货机内出现异常商品或商品丢失时,可以通过查看录像,还原所有用户的完整的购物过程。(1) Continuously monitor the customer's consumption process by arranging surveillance cameras. When the replenishment personnel or unmanned vending machine maintenance personnel find abnormal goods or lost goods in the vending machine, they can restore the complete shopping process of all users by viewing the video.
基于视频图像的风险控制解决方案无法提供有效的实时预警,只有当无人售货机运维人员发现售货机内的商品异常(有异常物品)或核对时发现商品丢失时,才能够发现风险,同时需要人工回放全部录像。此外,上述方案首先需要保存全部录像,占用无人售货机大量的存储空间,而如果通过网络回传视频到云端,则会占用大量网络带宽,运维成本急剧增加。同时,人工追溯视频会提高人力成本,且降低工作效率。基于纯视觉的行为识别算法目前尚不够准确,因此单独利用图像算法虽然能够节约存储空间,降低人力成本,但容易触发大量虚假报警,同时由于商品偷盗行为、异常置物行为与正常购物行为相似度高,很难利用算法区分,因此容易发生漏报,留下安全隐患。The risk control solution based on video images cannot provide effective real-time early warning. Only when the unmanned vending machine operation and maintenance personnel finds that the merchandise in the vending machine is abnormal (there are abnormal items) or the product is lost during verification, it can detect the risk. All videos need to be played back manually. In addition, the above solution first needs to save all the videos and occupy a lot of storage space of the unmanned vending machine. If the video is returned to the cloud through the network, it will occupy a lot of network bandwidth and the operation and maintenance cost will increase dramatically. At the same time, manually tracing video will increase labor costs and reduce work efficiency. The behavior recognition algorithm based on pure vision is not accurate enough at present. Therefore, although the image algorithm alone can save storage space and reduce labor costs, it is easy to trigger a large number of false alarms. At the same time, due to the theft of goods, the abnormal storage behavior and the normal shopping behavior are similar It is difficult to distinguish using algorithms, so false negatives are prone to occur, leaving security risks.
(2)当无人售货机发现重力异常时,可以提供后台报警,运维人员可根据警情,到现场查看售货机情况,排除隐患。(2) When an unmanned vending machine discovers gravity anomalies, it can provide a background alarm, and the operation and maintenance personnel can go to the scene to check the vending machine situation according to the police situation to eliminate hidden dangers.
基于重力的解决方案中,重力传感器能够时刻监控被取走或放回商品的重量,从而实现扣款。然而,当用户取走商品但是放回等重量的无用物品(比如沙子)或危险品时,无人售货机无法及时预警,从而导致高货损与高风险。同时由于不具备图像监控功能,因此当发现无人售货机出现异常商品时,无法进行追溯,无法定位何时、何人人偷盗了商品或置入了危险品。In the gravity-based solution, the gravity sensor can monitor the weight of the goods taken or returned at any time, so as to realize the deduction. However, when the user takes the goods but puts back the same weight of useless items (such as sand) or dangerous goods, the unmanned vending machine cannot promptly warn in time, resulting in high cargo damage and high risk. At the same time, because there is no image monitoring function, when it is found that there are abnormal goods in the unmanned vending machine, it cannot be traced back, and it cannot be located when and who has stolen the goods or placed dangerous goods.
通过本公开上述实施例中的方法,能够根据图像分析的结果发现异常行为,并在发现异常情况时及时触发上报异常图像,一方面降低了数据传输的负担,成数量级的 降低了人工判读、回溯的工作量;另一方面还能够提高异常情况发现的效率,另外,还能够降低漏判的概率,提高售货安全性。Through the method in the above embodiments of the present disclosure, abnormal behavior can be discovered based on the results of image analysis, and abnormal image reporting can be triggered in time when an abnormal situation is discovered. On the one hand, the burden of data transmission is reduced, and manual interpretation and backtracking are reduced by orders of magnitude. On the other hand, it can also improve the efficiency of abnormal situation detection, in addition, it can also reduce the probability of missed judgment and improve the safety of sales.
在一些实施例中,为了应对违规用户将从售货机中取出的物品中掺入异常物质(如注射有毒液体),或置换为其他的外观相同、相似的物品重新放回售货机的情况,本公开的售货机控制方法的又一些实施例的流程图如图3所示。In some embodiments, in order to cope with the situation where the illegal user mixes an abnormal substance (such as an injection of toxic liquid) into the item taken out from the vending machine, or replaces it with another item of the same appearance and similarity and put it back in the vending machine, this book A flowchart of still other embodiments of the disclosed vending machine control method is shown in FIG. 3.
在步骤301中,根据图像或重力探测确定货物被取出售货机。In step 301, it is determined that the goods are taken out and sold according to the image or gravity detection.
在步骤302中,记录被取出的货物的唯一标识。在一些实施例中,每个货物可以配置有唯一标识,如RFID标识。当用户结账关闭售货机后,删除记录的货物的唯一标识。In step 302, the unique identification of the removed goods is recorded. In some embodiments, each cargo may be configured with a unique identification, such as an RFID identification. When the user closes and closes the vending machine, the unique identifier of the recorded goods is deleted.
当根据图像或重力探测确定货物被放回售货机时,触发执行步骤303。When it is determined that the goods are returned to the vending machine according to the image or gravity detection, step 303 is triggered to be executed.
在步骤303中,采集放回的货物的标识,并判断与取出的货物的标识是否匹配。若两者匹配,则执行步骤305;若两者不匹配,则执行步骤304。In step 303, the identification of the returned goods is collected, and it is determined whether it matches the identification of the removed goods. If the two match, go to step 305; if the two do not match, go to step 304.
在步骤304中,缓存当前时刻,或截取采集的本次售货过程的图像作为高风险图像。In step 304, the current time is buffered, or the collected image of the sales process is intercepted as a high-risk image.
在步骤305中,判断用户是否对货物做出异常操作。异常操作可以包括破坏货物外包装、向货物内部加入物质、从货物中取物质或用户持货物离开摄像头探测区域后又返回中的一项或多项。若确定用户做出异常操作,则执行步骤304。若确定用户未做出异常操作,则执行步骤306。In step 305, it is determined whether the user has performed an abnormal operation on the goods. The abnormal operation may include one or more of destroying the outer packaging of the goods, adding substances to the inside of the goods, taking substances from the goods, or returning from the camera detection area after the user holds the goods. If it is determined that the user makes an abnormal operation, step 304 is executed. If it is determined that the user has not performed an abnormal operation, step 306 is executed.
在步骤306中,确定用户正常放回物品,删除标识。In step 306, it is determined that the user returns the item normally, and the logo is deleted.
通过这样的方法,能够应对将从售货机中取出的物品中掺入异常物质(如注射有毒液体),或置换为其他的外观相同、相似的物品重新放回售货机的情况,进一步提高了售货机贩卖物品的安全性。Through this method, it is possible to cope with the situation in which abnormal substances (such as injection of toxic liquids) are mixed into the items taken out of the vending machine, or replaced with other items with the same appearance and similarity and then put back into the vending machine, which further improves the sales. The safety of goods sold by cargo planes.
本公开的售货机控制方法的再一些实施例的流程图如图4所示。A flowchart of still other embodiments of the vending machine control method of the present disclosure is shown in FIG. 4.
在步骤401中,接收来自用户的开门请求。用户的开门请求中可以包括用户的个人身份信息,如用户对于售货机,或售货机相关的平台的账号信息,或身份证号码信息等。In step 401, a door opening request from the user is received. The user's door opening request may include the user's personal identity information, such as the user's account information for the vending machine, or the platform related to the vending machine, or ID number information.
在步骤402中,将用户身份信息上传平台判断用户是否为限制用户。若确定为限制用户,则执行步骤403;若确定为正常用户,则执行步骤404。In step 402, the user identity information is uploaded to the platform to determine whether the user is a restricted user. If it is determined to be a restricted user, step 403 is performed; if it is determined to be a normal user, step 404 is performed.
在步骤403中,拒绝触发售货机开门。In step 403, refusal to trigger the vending machine to open the door.
在步骤404中,触发售货机开门。In step 404, the vending machine is triggered to open the door.
在步骤405中,判断在购物过程中产生了高风险图像。在一些实施例中,可以采用如图2、3所示实施例中的方式确定是否产生高风险图像。在一些实施例中,当确定产生高风险图像时,可以先缓存高风险图像以便后续上报。若确定产生(缓存)了高风险图像,则执行步骤406。In step 405, it is determined that a high-risk image was generated during the shopping process. In some embodiments, the method shown in the embodiments shown in FIGS. 2 and 3 may be used to determine whether to generate a high-risk image. In some embodiments, when it is determined to generate a high-risk image, the high-risk image may be cached first for subsequent reporting. If it is determined that the high-risk image is generated (cached), step 406 is executed.
在步骤406中,向服务器上报高风险图像。在一些实施例中,可以先从产生的高风险图像中提取部分帧,只上报提取的图像帧,从而降低数据传输负担。In step 406, the high-risk image is reported to the server. In some embodiments, some frames may be extracted from the generated high-risk image first, and only the extracted image frames are reported, thereby reducing the data transmission burden.
在步骤407中,服务器发出告警,以便工作人员人工识别,或采用进一步的图像识别方法判读高风险图像。In step 407, the server issues an alarm so that the staff can manually identify it, or use a further image recognition method to interpret the high-risk image.
在步骤408中,根据高风险图像确定用户是否执行违规操作。若确定用户执行了违规操作,则执行步骤409;若确定用户未执行违规操作,则认为当前出现了误判,执行步骤412。In step 408, it is determined whether the user performs a violation operation based on the high-risk image. If it is determined that the user has performed the violation operation, step 409 is performed; if it is determined that the user has not performed the violation operation, it is considered that a misjudgment has occurred, and step 412 is performed.
在步骤409中,判断该用户违规操作统计值是否达到了预定门限。若已达到预定门限,则执行步骤411;若未达到预定门限,则执行步骤410。In step 409, it is determined whether the statistical value of the user's illegal operation has reached a predetermined threshold. If the predetermined threshold has been reached, step 411 is performed; if the predetermined threshold has not been reached, step 410 is performed.
在步骤410中,增加记录的用户违规操作统计值。在一些实施例中,还可以根据用户当前违规操作的种类确定增加的统计值的量,如普通违规操作加1,恶意违规操纵加10等。In step 410, the recorded user violation operation statistical value is increased. In some embodiments, the amount of increased statistical value may also be determined according to the type of the user's current violation operation, such as a common violation operation plus 1, a malicious violation manipulation plus 10, and so on.
在步骤411中,修改用户权限为限制用户。In step 411, the user right is modified to restrict the user.
在步骤412中,利用高风险图像更新图像分析训练数据集。In step 412, the image analysis training data set is updated with high-risk images.
在步骤413中,根据更新后的图像分析训练数据集更新图像特征和图像分析模型,并发送给提供给售货机更新售货机本地的图像特征和图像分析模型。在一些实施例中,考虑到售货机的存储空间和数据处理负担,可以只发送给提供了该高风险图像的售货机,在避免售货机数据量过多的同时,也能够针对售货机所处的环境、所经历的情况实现动态更新。In step 413, the image features and the image analysis model are updated according to the updated image analysis training data set, and sent to the vending machine to update the local image features and the image analysis model. In some embodiments, considering the storage space and data processing burden of the vending machine, it can only be sent to the vending machine that provides the high-risk image, while avoiding excessive vending machine data, it can also target the vending machine's location. The environment and the situation experienced are dynamically updated.
通过这样的方法,能够根据用户违规操作情况动态改变用户的权限,预防用户进一步违规操作,提高安全性;还能够动态更新图像分析的数据基础,图像提取特征和模型,提高售货机图像分析的准确性,降低错误判断的概率。由于在售货机使用过程中,能够通过有效的在线自反馈机制进行在线的难例挖掘,寻找不容易被准确识别的图像并回传,使售货机实现模型的自我迭代与优化,从而快速适应部署新环境、新商品的图像识别需求,节省大量训练图像的图像采集成本,同时图像识别准确度的提升也会进一步提高用户体验、减少货物损失。Through this method, the user's authority can be dynamically changed according to the user's illegal operation, preventing the user from further illegal operation and improving security; it can also dynamically update the data foundation of image analysis, image extraction features and models, and improve the accuracy of vending machine image analysis To reduce the probability of wrong judgment. During the process of using the vending machine, it is possible to mine difficult examples online through an effective online self-feedback mechanism, find images that are not easily recognized accurately and return them, so that the vending machine realizes self-iteration and optimization of the model, thus quickly adapting to deployment The new environment and new product image recognition requirements save a lot of image acquisition costs of training images, and the improvement of image recognition accuracy will further improve user experience and reduce cargo losses.

The abnormal operations include destroying the outer packaging of the goods, adding substances into the goods, One or more items taken from the goods or the user left the camera detection area with the goods and returned to the camera; or, the size, color or transparency of the goods were changed, thereby reducing the possibility of leaking violations and further improving safety Sex.
在一些实施例中,上报单元502可以先从缓存的高风险图像中筛选部分高风险图像帧,再将筛选出的高风险图像帧上报售货机控制服务器,并删除缓存区缓存的高风险图像。在一些实施例中,可以删除部分像素低的帧,或从极为相似的帧中选择几帧。这样的售货机控制装置能够降低需要上报给服务器的数据量,一方面降低数据传输负担,另一方面提高数据传输效率,便于服务器侧对于违规操作的迅速反应。In some embodiments, the reporting unit 502 may first select a portion of the high-risk image frames from the cached high-risk images, and then report the selected high-risk image frames to the vending machine control server, and delete the cached high-risk images. In some embodiments, some frames with low pixels can be deleted, or a few frames can be selected from very similar frames. Such a vending machine control device can reduce the amount of data that needs to be reported to the server, on the one hand reduce the data transmission burden, on the other hand improve the data transmission efficiency, and facilitate the server side to quickly respond to illegal operations.
