[0066] Figure 1 This is a schematic diagram of the structure of the remote examination monitoring system of the present invention. Figure 1As shown, the remote examination monitoring system of the present invention includes: several monitoring components and a server. The monitoring components include: a table 1, a camera device 4, an eye tracker 8 and a processing unit (not shown in the figure). Table 1 is used to place the test paper 5. The camera device 4 is set on the table 1 to shoot the desktop 11 of the table 1. The eye tracker 8 is set on the table 1 to collect the user's facial image and obtain the focus area 81 of the desktop 11 of the table 1 where the user's gaze falls in real time. The processing unit is connected to the camera device 4, the eye tracker 8 and the server respectively. The processing unit compares different frames of the video collected in real time by the camera device 4 to obtain the current handwriting position. When the time of separation between the focus area and the handwriting position exceeds the preset threshold, the preset threshold value ranges from 5 to 20 seconds, but is not limited thereto. Obviously, if you do not look at the writing position for a long time, there is suspicion of cheating methods such as peeking at the notes, and a cheating alarm operation is performed.

[0067] In a preferred embodiment, the processing unit compares different frames of the video captured in real time by the camera device 4 to obtain the current handwriting position, including:

[0068] The previous video frame image and the current frame image acquired in real time by the camera device 4 are divided into different grid areas based on a preset grid matrix, and each grid area of ​​the previous video frame image is compared with the grid area corresponding to the current frame image for image similarity, and the grid area with image similarity less than a preset threshold is used as the handwriting position, but not limited to this. In the present invention, the existing image similarity is used to calculate the similarity of the two corresponding grid areas of the previous video frame image and the current frame image, which will not be repeated here. For example: a 100*100 grid is preset to cut each video frame, then each video frame becomes a matrix formed by 10,000 grid areas arranged in 100 rows and 100 columns. Then the grid area Q of the first row from top to bottom and the first column from left to right of the current frame image is (1，1) The grid area P of the first row from top to bottom and the first column from left to right of the previous video frame image (1，1) Perform image similarity calculation, and then calculate each grid area Q (1，1) Thus, the difference between the current frame image and the previous video frame image is obtained as the handwriting position 41 of the current video frame, but the present invention is not limited thereto.

[0069] In a preferred embodiment, the processing unit compares different frames of the video captured in real time by the camera device 4 to obtain the current handwriting position, including the following steps:

[0070] The previous video frame image acquired by the camera device 4 in real time is subjected to graphic recognition to obtain the first recognized text, and the current frame image is subjected to graphic recognition to obtain the second recognized text. When the second recognized text has one more new character than the second recognized text, the position of the new character in the image is used as the handwriting position of all video frames after the previous character is completed, but it is not limited to this. (For example: if a student uses 10 frames to write an "A", he will start writing "B" from the 11th frame and will not finish writing "B" until the 20th frame. The text in the 20th frame recognizes the new character "B", and the position of the character "B" in the image is used as the handwriting position 41 of each frame from the 11th frame to the 20th frame.), but it is not limited to this.

[0071] In a preferred embodiment, each monitoring component also includes a wide-angle camera device 9 for photographing the user and the test paper 5. The wide-angle camera device 9 is connected to the processing unit. The server is connected to the processing unit of each monitoring component through a network. The processing unit uploads the video taken by the wide-angle camera device 9 to the server based on the triggering of the cheating alarm operation, but is not limited to this.

[0072] In a preferred embodiment, the eye tracker 8 captures the user's facial image and inputs it into a head posture model to obtain the focus area 81 of the desktop 11 where the user's current gaze falls. The head posture model is obtained based on training of sample facial images of the user at different times and the focus area of ​​the desktop 11 of the table 1 corresponding to the sample facial images, but is not limited to this.

[0073] In a preferred embodiment, the device further includes a support arm 2 connected to the tabletop 11. A lighting device 3 is connected to the support arm 2 and suspended above the tabletop 11. The lighting device 3 includes a lampshade and a light bulb disposed therein. The camera 4 is a camera disposed within the lampshade, with the camera's light input direction perpendicular to the tabletop 1, but this is not limiting.

[0074] In a preferred embodiment, the support arm 2 and the eye tracker 8 are arranged on the same side of the desktop 11, the lighting device 3 is arranged at the upper end of the support arm 2 away from the desktop 11, and the eye tracker 8 is integrated with the lower part of the support arm 2, but not limited to this.

[0075] Figures 2 to 4 This is a schematic diagram of the implementation process of the remote examination monitoring system of the present invention. Figure 2The remote examination monitoring system of the present invention includes a table 1, a support arm 2, a lighting device 3, a camera device 4, an eye tracker 8 and a wide-angle camera device 9. A reading material is placed on the desktop 11 of the table 1. The support arm 2 is connected to the desktop 11. The lighting device 3 is connected to the support arm 2 and is suspended above the desktop 11. The lighting device 3 includes a lampshade and a light bulb arranged in the lampshade. The camera device 4 is a camera arranged in the lampshade. The light input direction of the camera is perpendicular to the table 1 and shoots the desktop 11 of the table 1. The eye tracker 8 is set on the table 1 to collect the user's facial image and obtain the focus area 81 where the user's gaze falls on the desktop 11 of the table 1. In this embodiment, the support arm 2 and the eye tracker 8 are arranged together on the same side of the desktop 11 (which can be the side away from the user, but is not limited to this). The lighting device 3 is arranged at the upper end of the support arm 2 away from the desktop 11, and the eye tracker 8 is integrated with the lower part of the support arm 2. The processing unit (not shown in the figure) is respectively connected to the camera device 4, the wide-angle camera device 9 and the eye tracker 8. The student 6 sits in front of the table 1, spreads the test paper 5 on the desktop 11, and writes on the test paper 5 with a pen. The lighting device 3 illuminates the test paper 5. The lighting device 3 takes a photo of the test paper 5 on the desktop 1 and sends it to the processing unit. The eye tracker 8 captures the facial image of the student 6.

[0076] refer to Figure 3 and 4 , compare different frames of the video captured by the camera device 4 in real time. In this embodiment, the first recognized text is obtained by performing graphic recognition on the previous video frame image captured by the camera device in real time, and the second recognized text is obtained by performing graphic recognition on the current frame image. When the second recognized text has one more new character than the second recognized text, the position of the new character in the image is used as the handwriting position 41 of all video frames after the previous character is completed, thereby locating the current handwriting position 41 in real time. When the time for the focus area 81 to separate from the handwriting position 41 exceeds the preset threshold (10 seconds), when the user writes on the test paper but does not look at the test paper for a long time, the greatest possibility is that he is suspected of cheating by means such as peeking at the cheat sheet, and a cheating alarm operation is performed, and the video captured by the wide-angle camera device 9 that shoots the user and the test paper 5 is uploaded to the server.

[0077] In a preferred embodiment, the server will display a wide-angle video of several candidates who have been alarmed for cheating in a split-screen format. Since the wide-angle video is more likely to capture cheating actions, it is easier for the invigilator to detect cheating in a remote location in a timely manner.

[0078] The camera device 4 and the eye tracker 8 cooperate to perform position comparison and separation time statistics between the focus area and the handwriting position. Through this screening method, students suspected of cheating are identified from a large number of students, and then the videos of these students are uploaded, thereby greatly reducing the traffic cost and personnel cost required for supervision. It enables a teacher to remotely supervise a large number of students and detect cheating problems in a timely manner.

[0088] When the first recognized text has one more new character than the second recognized text, the position of the new character in the image is used as the handwriting position of all video frames after the previous character is completed, but not limited to this.

[0089] In a preferred embodiment, each monitoring component also includes a wide-angle camera device for photographing the user and the test paper. The wide-angle camera device is connected to the processing unit. The server is connected to the processing unit of each monitoring component through a network. The processing unit uploads the video taken by the wide-angle camera device to the server based on the triggering of the cheating alarm operation, but is not limited to this.

[0090] In a preferred embodiment, an eye tracker collects a facial image of the user and inputs it into a head posture model to obtain a focus area on the desktop where the user's current gaze falls.
