When the accuracy of the model output reaches the preset specified value, the training is completed and the candidate behavior recognition model is obtained.

[0017] Step S200: When the examinee has abnormal behavior, generate a manual preliminary review instruction, conduct a preliminary review based on the manual preliminary review instruction, and determine whether to wake up the review instruction; wherein the preliminary review means prompting the staff of the preliminary review end to conduct a preliminary video review based on the manual preliminary review instruction to determine whether the student with abnormal behavior is suspected of cheating, so as to determine whether to wake up the review instruction; Specifically, it includes: when a candidate has abnormal behavior, a manual preliminary review instruction is generated, the abnormal video clip corresponding to the abnormal behavior is intercepted, and sent to the manual review end; a manual preliminary review is conducted based on the manual review end to determine whether it is abnormal; when the manual preliminary review determines that it is abnormal, the review instruction is awakened, and the candidate with abnormal behavior is marked as an abnormal candidate; when the manual preliminary review determines that it is normal, there is no need to wake up the review instruction, and the candidate with abnormal behavior is determined to be a normal candidate.

[0018] Step S300: when the review instruction is awakened, the target mobile inspector is determined according to the abnormal examinee location information and the mobile inspector location information; Step S400: Generate a recommended walking route based on the location information of the target mobile inspector and the location information and seat orientation information of the abnormal examinee, and send a review prompt message to the user terminal of the target mobile inspector.

[0019] In this embodiment, in the present invention, mobile inspectors are set up for each examination. The mobile inspectors review the abnormal candidates identified by the system. When the mobile inspectors do not receive the review prompt information, all mobile inspectors cycle around all examination rooms in batches to conduct mobile inspections. Based on the behavior recognition model, the behavior of the examinee is identified, and it is determined whether the examinee has abnormal behavior. When the examinee has abnormal behavior, a preliminary review is performed based on the manual preliminary review instruction, and it is determined whether to wake up the review instruction; when the review instruction is woken up, the target mobile inspector is determined according to the abnormal examinee location information and the mobile inspector location information, and a recommended walking route is generated according to the target mobile inspector location information and the abnormal examinee location information and seat orientation information, and a review prompt information is sent to the user terminal of the target mobile inspector.

Based on the position information of the mobile inspector and the position information and seat orientation information of the abnormal candidate, the mobile inspector behind the seat of the abnormal candidate is obtained as the back-facing inspector, and the mobile inspector who is closest to the abnormal candidate among the back-facing inspectors is obtained as the target mobile inspector; the inspector behind the abnormal candidate is retrieved, and the possibility of discovering the target mobile inspector in the abnormal candidate is effectively avoided. By obtaining the mobile inspector who is closest to the abnormal candidate among the back-facing inspectors as the target mobile inspector, the mobile inspectors can promptly discover and stop the cheating behavior of the candidates, effectively improving the anti-cheating effect and ensuring the accuracy of cheating detection.

[0022] As a preferred embodiment of the present invention, the step of generating a recommended walking route according to the location information of the target mobile inspector and the location information and seat orientation information of the abnormal examinee, and sending a review prompt information to the user terminal of the target mobile inspector comprises: When there is a candidate facing away from the examiner, obtain the location information of the entrance and exit doors of the examination room where the abnormal candidate is located. Each examination room usually has two entrance and exit doors. Determine the target entrance door according to the location information of the entrance door of the examination room where the abnormal candidate is located and the seat orientation information of the abnormal candidate, wherein the target entrance door is behind the seat of the abnormal candidate; Generate a recommended walking route based on the location information of the target mobile inspector, the location information of the target entrance door, and the location information of the abnormal examinee, wherein the recommended walking route is the shortest route based on passing through the target entrance door; when there is no inspector facing away from the examinee, there is no need to generate a recommended walking route; Sending a review prompt message to the user terminal of the target mobile inspector, wherein the review prompt message carries the examination room information and seat number information of the abnormal examinee and the recommended walking route information; Receiving a receipt message for the review prompt message sent by a user terminal corresponding to the target mobile inspector; Determine whether the review prompt information is executed based on the receipt information; when the review prompt information is executed, the review instruction allocation is completed; when the review prompt information is not executed and exceeds the preset time threshold, eliminate the current target mobile inspector and update the latest target mobile inspector so that the review prompt information is executed.

[0023] In this embodiment, when there is an inspector with his back to the examinee, the target entrance door is determined based on the position information of the entrance and exit doors of the examination room where the abnormal examinee is located and the seat orientation information of the abnormal examinee, and a recommended walking route is generated based on the position information of the target mobile inspector, the position information of the target entrance door and the position information of the abnormal examinee. The recommended walking route is the shortest route based on the target entrance door, so as to realize a surprise inspection and review of the abnormal examinee from behind, effectively avoiding the possibility of the abnormal examinee discovering the target mobile inspector, and ensuring that the target mobile inspector can promptly and accurately discover the cheating behavior of the abnormal examinee.
