[0002] In recent years, as the whole society attaches more importance to and pays more attention to art knowledge and art majors, students' enthusiasm for art-related majors and the number of people taking the art college entrance examination have also increased. However, due to the particularity of the art major, the works to be evaluated are the art works drawn by the candidates during the examination. The authenticity of the submitted works cannot be confirmed during the online examination, so on-site examinations are often required.

[0003] Since art exams require on-site registration and examination, they involve many people and have a long operation cycle. They are easily disturbed by external factors and have low organizational efficiency. They will waste a lot of candidates' time, money and energy, and also cause a waste of social resources.

[0066] The present invention will be further described in detail below with reference to the examples. The following examples are intended to explain the present invention but the present invention is not limited to the following examples.

[0067] Example 1: A remote art examination system is connected to an external server 200 signal, such as Figure 1 As shown, the art remote examination system (hereinafter referred to as the examination system) includes a monitoring device 110, a painting collection device 120 and a candidate terminal 130, wherein the monitoring device 110 is directly connected to the server 200 signal or is connected to the server 200 signal through the candidate terminal 130, wherein the candidate terminal 130 is connected to the server 200 signal, and the painting collection device 120 is directly connected to the server 200 signal or is connected to the server 200 signal through the candidate terminal 130.

[0068] Figure 1 The solid line indicates connection via Internet signal, and the dotted line indicates connection via Bluetooth or signal line signal.

[0069] The monitoring device 110 and the drawing collection device 120 are used to upload the collected data to the server 200, and the server 200 performs cheating judgment and obtains the corresponding cheating judgment result;

[0070] The monitoring device 110 is used to collect video of the examinee and the examination area 10 to obtain monitoring video data;

[0071] The drawing collection device 120 is used to collect the examinee's operation data during the examination, wherein the operation data includes brush stroke data and pressure data, and is also used to collect the examinee's work data at the end of the examination;

[0072] The candidate terminal 130 is used for candidate login and is also used to obtain and display the test information issued by the server 200;

[0073] The candidate terminal 130 is a computer or a mobile terminal such as a mobile phone or a pad.

[0074] This embodiment, through the design of the monitoring device 110, can determine the identity of the examinee to prevent others from taking the exam on their behalf, and can also detect cheating based on the surveillance video data that records the entire exam process.

[0075] Since art exams are different from ordinary exams, candidates in ordinary exams fill in their answers in the designated response area, but in art exams, candidates are required to submit completed works, which makes it easy for candidates to replace their papers. To address this issue, this embodiment designs a painting acquisition device 120, which collects the candidate's work data and the brush stroke data and pressure data during the painting process. Further cheating judgment is made based on the work data, brush stroke data and pressure data, thereby effectively ensuring the authenticity of the works submitted by the candidates and the fairness of the art exam.

[0076] Specifically:

[0077] The drawing collection device 120 includes a drawing board 121, such as Figure 2 As shown, the drawing board 121 includes a housing 1210 , and a drawing clip 1211 is provided on the housing 1210 . The drawing clip 1211 is used to fix the drawing paper on the drawing board 121 .

[0078] like Figure 3 As shown, the housing 1210 is provided with a drawing board control module 1213, and a drawing board communication module 1214, a drawing module 1212 and a pressure detection module 1215 which are signal-connected to the drawing board control module 1213;

[0079] The drawing module 1212 is used to collect brushstroke data during the examinee's drawing process, and is also used to collect the examinee's work data based on the drawing module 1212 at the end of the test; the brushstroke data is the pressure data caused by the examinee on the drawing module 1212 when the examinee draws and the time data of the pressure generation. In this embodiment, the sensing height of the drawing module 1212 is 10 mm and the reading speed is 266 points / second; the work data is the image data of the painting at the end of the test, and the examinee's painting level is evaluated based on the work data.

[0080] The pressure detection module 1215 is used to monitor the pressure data of the drawing clip 1211 on the housing 1210;

[0081] The drawing board communication module 1214 is used to connect to the candidate terminal 130 and / or the server 200 by signal;

[0082] The drawing board control module 1213 is used to obtain test information from the examinee terminal 130 and / or the server 200 through the drawing board communication module 1214, and control the operation of the drawing board communication module 1214, the drawing module 1212 and the pressure detection module 1215 based on the test information.

[0083] In art examination subjects, subjects such as sketching and quick sketching can be painted directly on the drawing module 1212, and the drawing module 1212 generates the work data. However, subjects such as watercolor need to be painted on drawing paper, which makes it easy to replace the paper.

[0084] Therefore, this embodiment monitors the behavior of replacing the drawing paper through the drawing folder 1211 and the pressure detection module 1215. That is, before the test, the drawing paper is fixed on the shell 1210 through the drawing folder 1211, and the pressure sensor monitors the pressure of the drawing folder 1211 on the shell 1210 in real time. If the examinee replaces the drawing paper, he must open the drawing folder 1211. At this time, the pressure of the drawing folder 1211 on the shell 1210 will be reduced, so that it can be judged whether the examinee has replaced the drawing paper based on the monitored pressure data, thereby ensuring the fairness of the remote art test.

[0085] When the drawing paper is fixed on the housing 1210 by the drawing clip 1211 , the drawing area on the drawing paper is located on the upper surface of the drawing module 1212 . When the examinee draws, the drawing module 1212 collects corresponding stroke data.

[0086] In an examination based on drawing paper, the monitoring device 110 can collect work data at the end of the examination, and the original work can be handed in, and the scoring teacher will evaluate the work based on the photographed work data and the original work.

[0087] Further:

[0088] The drawing collection device 120 further includes a drawing brush 122 and a scanning device 123, wherein the drawing brush 122 is signal-connected to the drawing board communication module 1214 and / or the examinee terminal 130, and the scanning device 123 is signal-connected to the drawing board communication module 1214 and / or the examinee terminal 130;

[0089] The paintbrush 122 is used to paint on the drawing module 1212 and also to collect the examinee's fingerprint data;

[0090] The scanning device 123 is used to collect the data of the work drawn by the examinee based on the drawing paper at the end of the examination. The examinee does not need to submit the original drawing, which facilitates online evaluation of the drawing. In actual use, the examinee uses the scanning device 123 to collect the drawing fixed on the drawing board 121 within the specified time to obtain the work data. In order to further avoid paper replacement, the number of the drawing board 121 can also be marked on the drawing folder 1211. The work data collected by the scanning device 123 includes the number of the drawing board 121, so that the subsequent server 200 can verify the authenticity of the work data by identifying the number of the drawing board 121 in the work data.

[0091] In this embodiment, the brush 122 is designed to collect the examinee's fingerprint data before and / or during the examination to verify the examinee's identity and avoid the situation where someone else takes the examination on his or her behalf.

[0092] The paintbrush 122 includes a pen housing, a fingerprint collection module located in the inner cavity of the pen housing, and a paintbrush 122 communication module, wherein the fingerprint collection module and the paintbrush 122 communication module are signal-connected;

[0093] The collection end of the fingerprint collection module is embedded in the pen shell and is used to collect the examinee's fingerprint data;

[0094] The brush 122 communication module is connected to the drawing board communication module 1214 by signal. In this embodiment, the brush 122 communication module sends the fingerprint data to the drawing board communication module 1214 via Bluetooth communication, and the drawing board communication module 1214 sends it to the examinee terminal 130.

[0095] Further:

[0096] Also included is a relay device;

[0097] The monitoring device 110 includes a video monitoring module 111 and a plurality of infrared monitoring modules 112;

[0098] The video monitoring module 111, the drawing acquisition device 120, the examinee terminal 130 and / or the plurality of infrared monitoring modules 112 transmit data with the server 200 via the relay device;

[0099] The relay device user saves the data collected by each device and uploads the data to the server 200, and is also used to distribute the test information sent by the server 200 to the corresponding devices.

[0100] This embodiment can store the data collected by each device locally through the design of the relay device, avoiding data loss due to network signal interruption, and effectively preventing candidates from tampering with the data collected by each device, ensuring that candidates can complete the exam while ensuring the fairness of the exam.

[0101] The video monitoring module 111 is used to collect video of the examinees and the examination area 10 to obtain monitoring video data;

[0102] The infrared monitoring modules 112 are evenly distributed at the edge of the examination room area 10 and are used to monitor the entry and exit of personnel during the examination and generate corresponding infrared data.

[0103] Through the design of the infrared monitoring module 112, this embodiment can effectively detect the entry and exit of people in the examination area 10 during the examination, and prevent others from entering the examination area 10 in the blind spot area captured by the video monitoring module 111 to assist candidates in completing the examination.

[0104] Further:

[0105] like Figure 4 As shown, the examination area 10 is the interior space of the tent;

[0106] The tent includes a tarpaulin and a support structure 11. When the support structure 11 supports the tarpaulin to form an examination area 10, the infrared monitoring modules 112 are evenly arranged on the tarpaulin, and the video monitoring module 111 is fixed to the top of the examination area 10 through the support structure 11.

[0107] The distance between the bottom of the tarpaulin and the ground is 10cm to 20cm, which is convenient for the circulation of air inside and outside the tent, and also convenient for power supply to electrical devices. The electrical devices include video monitoring module 111, candidate terminal 130, drawing board 121, scanning device 123 and other devices that need to draw power from an external power supply, as well as fans, electric lights and other daily electrical devices.

[0108] This embodiment uses the tent design to build an independent examination area 10, which further prevents candidates from cheating and effectively prevents candidates from being affected by the external environment during the examination.

[0109] In this embodiment, the support structure 11 is an existing liquid-elastic bracket that has been disclosed, which is convenient for candidates to build an examination space. The tarpaulin adopts a translucent opaque tarpaulin, such as a white translucent tarpaulin, so as to prevent cheating while avoiding the influence of light on the candidate's painting. The video monitoring module 111 is fixed on the support structure 11 and is located at the top center of the examination area 10. It can collect monitoring video data of the entire examination area 10.

[0110] Embodiment 2: A remote art examination system includes a server 200, and an examinee subsystem and an assessment subsystem connected to the server 200;

[0111] The assessment subsystem is the examination system described in Example 1, that is, the examinee subsystem includes:

[0112] The monitoring device 110 is used to collect video of the examinees and the examination area 10 to obtain monitoring video data;

[0113] The drawing collection device 120 is used to collect the operation data of the examinee during the examination, wherein the operation data includes brushstroke data, and is also used to collect the work data of the examinee's work at the end of the examination;

[0114] The examinee terminal 130 is used to obtain and display the examination information issued by the server 200, and is also used to obtain the data collected by the monitoring device 110 and / or the drawing collection device 120 and upload it to the server 200, which makes cheating judgments and obtains corresponding cheating judgment results.

[0115] The method for conducting a remote art examination based on the examination system proposed in this embodiment is as follows:

[0116] Before the exam:

[0117] The examinee uploads the examinee registration information and address information to the server 200 through the examinee terminal 130 to register online. The examinee registration information includes registration face data and registration fingerprint data. The examinee also pays the registration fee and equipment rental through the examinee terminal 130.

[0118] The assessment subsystem retrieves the candidate's registration information from the server 200 for information verification, and uploads the verification results to the server 200, which is then sent by the server 200 to the candidate's terminal 130 for feedback; when the verification is passed, the relevant examination equipment is mailed to the candidate based on the address information, and the logistics information is uploaded to the server 200, which is then sent by the server 200 to the candidate's terminal 130 for feedback. The relevant examination equipment includes a tent, a monitoring device 110, a drawing collection device 120 and a relay device.

[0119] The examinee receives relevant examination equipment and sets up the examination room environment. The video monitoring module 111 collects image data containing the examinee's face and the brush 122 collects the examinee's fingerprint data, and uploads the image data and fingerprint data to the server 200.

[0120] The server 200 performs facial recognition on the image data to obtain recognized facial data. When the registered facial data matches the recognized facial data, and the fingerprint data matches the registered fingerprint data, the monitoring device 110, the drawing acquisition device 120 and the relay device are activated. At this time, the monitoring device 110, the drawing acquisition device 120 and the candidate terminal 130 are all connected to the relay device signal. The relay device obtains the device identification of each device and uploads the device identification to the server 200, so that each device is bound to the candidate registration information.

[0121] During the exam:

[0122] Based on the candidate's terminal 130 logging into the examination page, the video monitoring module 111 collects image data containing the candidate's face, and the brush 122 collects the candidate's fingerprint data, and uploads the image data and fingerprint data to the server 200. The server 200 verifies the candidate's identity to prevent proxy examinations;

[0123] After successful identity verification, the candidate terminal 130 generates an exam application and sends it to the server 200. The server 200 then sends the exam information, including content and timing information, to the corresponding relay device. The relay device then forwards the information to the candidate terminal 130, which then feeds it back to the candidate.

[0124] When the test begins, the relay device controls the monitoring device 110 and the drawing device according to the test information;

[0125] The video monitoring module 111 collects monitoring video data in real time and sends the monitoring video data to the server 200 through a relay device;

[0126] The infrared monitoring data collects infrared data in real time and sends the infrared data to the server 200 through the relay device;

[0127] The drawing module 1212 collects brushstroke data in real time and sends the brushstroke data to the server 200 via a relay device;

[0128] The pressure detection module 1215 collects pressure data in real time and sends the stroke data to the server 200 via a relay device;

[0129] When the examination ends, that is, when the examination ends or the examinee voluntarily submits the examination paper, the drawing module 1212 or the scanning device 123 collects the work data and sends the stroke data to the server 200 via the relay device;

[0130] The server 200 performs cheating judgment based on the received surveillance video data, infrared data, brush stroke data, pressure data, and work data, and records the cheating judgment result;

[0131] The assessment subsystem retrieves each examinee's work data and cheating judgment results from the server 200, verifies the cheating judgment results, assesses the non-cheating work data, generates scores and uploads the scores to the server 200, which is then sent to the corresponding examinee terminal 130 for feedback.

[0132] Example 3: A remote art examination method based on the remote art examination system described in Example 2, which includes a cheating judgment method performed by the server 200, such as Figure 5 As shown, the specific steps include:

[0133] S100, receiving monitoring video data collected by the video monitoring module 111, performing identity authentication based on the monitoring video data, and obtaining an identity authentication result;

[0134] S200: When the identity verification result is successful, performing a video cheating determination based on the surveillance video data to obtain first cheating determination data; further receiving operation data and artwork data collected by the painting acquisition device 120, wherein the operation data includes brushstroke data; performing behavior verification based on the operation data to obtain second cheating determination data; and performing style verification based on the artwork data to obtain third cheating determination data;

[0135] S300: Generate a corresponding cheating judgment result based on the first cheating judgment data, the second cheating judgment data, and the third cheating judgment data.

[0136] Due to the particularity of art exams, some cheating behaviors cannot be monitored through the captured surveillance video data, such as plagiarism, substituting small movements for test papers, etc. Therefore, this embodiment also combines operation data and work data to monitor cheating from the examinee's painting behavior and the style of the examinee's work, and further verify the authenticity of the work.

[0137] In step S200 of this embodiment, a specific implementation method for performing video cheating judgment based on the monitoring video data to obtain first cheating judgment data is as follows:

[0138] The surveillance video data is segmented to obtain several video clips of fixed length, such as 5 minutes, so that video recognition can be performed on the surveillance video data in real time.

[0139] The obtained video clip is input into an existing publicly available video recognition model. The video recognition model identifies cheating events in the video clip and outputs a probability value for the presence of various types of cheating behaviors. Based on the probability value and a preset recognition threshold, the video recognition result is output, i.e., cheating or not cheating.

[0140] The video recognition results of all video clips are aggregated to generate first cheating judgment data.

[0141] In step S200 of this embodiment, the specific implementation method of performing style verification based on the work data to obtain the third cheating judgment data is as follows:

[0142] The examinee's work data is input into a preset style detection model, and the preset style detection model outputs a similarity. A style verification result is generated based on the similarity, and the style verification result is used as the third cheating judgment data. If the similarity exceeds a preset similarity threshold (90%), the style verification result is a successful verification, otherwise the verification fails.

[0143] Since the composition size, light and dark distinction, and line handwriting pattern of each person's painting are different, this embodiment uses the examinee's historical works to pre-train the corresponding style detection model based on this feature, so that the style detection model can be used to detect the consistency of the style of the examinee's completed work and his or her historical works, thereby ensuring the authenticity of the work.

[0144] In this embodiment, the examinee uploads his / her historical works in advance, or sets up the examination area 10 in advance, practices drawing in the examination area 10, and uploads the practice works to the server 200 via the drawing module 1212 or the scanning device 123;

[0145] The server 200 uses each examinee's historical works and / or practice works as style training samples, and constructs a corresponding style detection model for each examinee based on the style training samples;

[0146] Those skilled in the art can select an existing publicly available style detection network and use the style training samples of each examinee to train the style detection network to obtain a corresponding style detection model. Since the training of the model is an existing technology, there is no need to inform those skilled in the art in detail that they can also train to obtain a style detection model that can detect whether the style of the works is consistent, so it will not be introduced in detail in this specification.

[0147] Furthermore, the operation data also includes pressure data collected by the pressure detection module 1215;

[0148] At this time, in step S200, the specific implementation method of performing behavior verification based on the operation data to obtain the second cheating judgment data is as follows:

[0149] S210: Determine whether to perform test paper substitution monitoring based on the test information;

[0150] The examination information includes drawing tools, drawing paper or drawing board 121;

[0151] When the drawing tool is drawing paper, it is determined that a roll replacement detection is performed.

[0152] S220: When the paper replacement detection is not performed, performing drawing behavior monitoring based on the brushstroke data to obtain first behavior monitoring data, and using the obtained first behavior monitoring data as second cheating determination data;

[0153] In this embodiment, the collected stroke data is input into a pre-trained anomaly detection model, and the anomaly detection model outputs a corresponding anomaly score. Based on the anomaly score and a preset score threshold (which can be set according to actual conditions), an anomaly detection result is output, and the anomaly detection result is used as the first behavior monitoring data.

[0154] This embodiment pre-collects the pen stroke data of 5000 examinees during the three-month simulation test as training samples;

[0155] The stroke data includes behavior records such as pressure data on the drawing module 1212 when the examinee draws, time data of the pressure generation, and pressure drawing click stream data.

[0156] Based on an existing publicly available anomaly detection algorithm, such as the isolation forest algorithm, the training samples are trained to obtain an anomaly detection model.

[0157] Since model training is an existing technology, there is no need to inform those skilled in the art in detail that they can also obtain an anomaly detection model capable of detecting abnormal painting behavior based on isolation forest algorithm training, so it will not be introduced in detail in this manual.

[0158] S230. When performing paper-replacement detection, performing drawing behavior verification based on the brushstroke data to obtain corresponding first behavior monitoring data, and performing paper-replacement behavior monitoring based on the pressure data to obtain second behavior monitoring data, and using the first behavior monitoring data and the second behavior monitoring data as second cheating judgment data.

[0159] The method for monitoring the roll replacement behavior based on the pressure data is as follows:

[0160] A pressure value in the detected pressure data that is less than a preset pressure threshold is taken as an abnormal pressure value, and second behavior monitoring data is generated based on the value of each abnormal pressure value and the time when it is generated.

[0161] Further:

[0162] When the identity verification result is successful, the examination room supervision step is also included. The specific steps are as follows:

[0163] Obtaining infrared data collected by each infrared monitoring module 112, performing personnel entry and exit monitoring based on the infrared data, and obtaining fourth cheating judgment data;

[0164] That is, infrared data of a person is detected during the test time, that is, infrared data with a changed level, and the infrared data and the time when the infrared data is generated are used as the fourth cheating judgment data;

[0165] A corresponding cheating judgment result is generated based on the first cheating judgment data, the second cheating judgment data, the third cheating judgment data, and the fourth cheating judgment data.

[0166] When the recognition results of all video clips of the monitoring video data are all no cheating, the candidate's pen stroke data detected based on the isolation forest algorithm has no abnormal values ​​and / or no abnormal pressure values, the candidate's work data style verification is successful, and no infrared data of a person is detected, the cheating judgment result is no cheating; otherwise, the cheating judgment result is cheating, and the cheating judgment data are fed back to facilitate manual judgment by the examiner.

[0167] Further:

[0168] Receive surveillance video data collected by the video monitoring module 111 and fingerprint data collected by the brush 122;

[0169] Performing face verification based on the surveillance video data to obtain a face verification result;

[0170] Performing fingerprint verification based on the fingerprint data to obtain a fingerprint verification result;

[0171] An identity verification result is generated based on the face verification result and the fingerprint verification result. When both the face verification result and the fingerprint verification result are successful, the identity verification result is successful.
