[0027] See also Figure 1 The embodiment of the present invention provides an electronic police equipment integrated monitoring system used for traffic control, the system comprising: an induction screen 10, used to perform corresponding content display operations based on display instructions; an electronic police device 20, used to collect monitoring images / videos of the induction screen and feed back the monitoring images / videos; a main control center 30, electrically connected to the induction screen 10 and the electronic police device 20, used to generate and output corresponding display instructions based on display requirements, perform display analysis on the monitoring images / videos, and generate corresponding display monitoring results.

[0028] In a possible implementation, the functions of an existing electronic police device 20 are reused. The electronic police device 20 is, for example, a road monitoring camera. During use, on the one hand, the camera performs normative monitoring of vehicles on the road. On the other hand, when the camera is in an idle state (for example, when it monitors that there is no traffic passing through the current road) or when the deflection angle of the camera is at an angle facing the induction screen 10, the camera collects monitoring images / videos of the induction screen 10 and feeds back the monitoring images / videos.

[0029] The induction screen 10 is set beside the traffic road. The induction screen 10 is electrically connected to the main control center 30. During use, the main control center 30 sends corresponding display instructions to the induction screen 10 according to actual needs. For example, in one embodiment, the main control center 30 needs to control the induction screen 10 to display today's restricted number information, so the corresponding display instructions are generated according to the restricted number of the day and sent to the corresponding induction screen 10. After receiving the above display instructions, the induction screen 10 performs the corresponding content display operation. However, in actual application, the induction screen 10 may not display the expected content due to various reasons, such as failure or erroneous operation, and the management personnel may not be able to know it in time, thus causing trouble to the vehicle driver or affecting the work of the management personnel. Therefore, in order to solve the above technical problems, the main control center 30 also displays and analyzes the acquired monitoring images / videos to generate corresponding display monitoring results.

[0030] See also Figure 2 In the embodiment of the present invention, the display analysis of the monitoring image / video to generate the corresponding display monitoring result includes:

[0031] S10) obtaining a trained intelligent monitoring model;

[0032] S20) extracting features from the monitoring image / video based on the intelligent monitoring model to obtain display content features;

[0033] S30) judging whether the induction screen 10 is faulty based on the display content characteristics;

[0034] S41) If yes, output the corresponding first alarm information;

[0035] S42) otherwise, determining the display content based on the display content feature, judging whether the display content matches the display requirement, and outputting a first reminder message if the display content does not match the display requirement;

[0036] S50) Using the first alarm information or the first reminder information as the display monitoring result.

[0037] In a possible implementation, a trained intelligent monitoring model is first obtained, and then feature extraction is performed on the obtained monitoring image / video according to the intelligent monitoring model, and display content features are obtained. During use, the display content abnormalities of the induction screen are divided into two situations: active abnormalities and passive abnormalities. The passive abnormality is a failure of the induction screen 10. At this time, it is sufficient to directly notify the management personnel to perform maintenance and management on it, while the active abnormality requires corresponding measures to be taken according to the actual situation, such as online supervision measures, without having to send people to the site for processing. Therefore, in the process of supervising the display of the induction screen, it is first necessary to exclude the situation where it has failed. Specifically, the display content features are analyzed to determine whether the induction screen 10 has failed.

[0038] However, in actual application, the surveillance camera is generally configured to face the induction screen 10 or its image acquisition range includes the entire interface of the induction screen 10. However, on the one hand, the surveillance camera may be rotated manually during use, resulting in the surveillance camera still being unable to capture the entire interface of the induction screen 10 after a fixed rotation instruction is given to the surveillance camera; on the other hand, after the surveillance camera has been used for a long time, it may be unable to perform the set rotation action due to equipment aging, equipment failure, etc., which will also cause the surveillance camera to be unable to capture the entire interface of the induction screen 10, affecting the subsequent monitoring analysis.

[0039] In an embodiment of the present invention, the main control center 30 is also used to: before determining whether the induction screen is faulty, determine the border of the induction screen based on the display content characteristics; determine whether the induction screen is completely entered based on the border; if it is determined that the induction screen is not completely entered, output a first rotation control instruction for the electronic police device; obtain a first rotation image / video corresponding to the first rotation control instruction within a preset time, and determine whether the induction screen is completely entered based on the first rotation image / video: if the induction screen is not completely entered, output a corresponding second alarm message; if it is determined that the induction screen is completely entered, determine whether the display area corresponding to the induction screen is blocked based on the display content characteristics: if it is determined that the display area is not blocked, determine whether the induction screen is faulty; if it is determined that the display area is blocked, output a second reminder message.

[0040] In a possible implementation, the lens of the camera can be rotated according to the control command of the main control center 30, thereby realizing the functional reuse of normal road monitoring and the collection of display content of the induction screen 10. In the implementation process, the border of the induction screen 10 is determined according to the obtained display content characteristics. Specifically, the border features of the induction screen 10 are extracted from the actual content features, and it is analyzed whether it constitutes a complete border of the induction screen 10, and whether the induction screen 10 is completely recorded is determined based on the obtained border. For example, the main control center 30 pre-enters the size information of the induction screen 10, and calculates the length and width of the border of the induction screen 10 based on the size information to determine whether it is completely recorded. During the calculation, since the camera may not be facing the induction screen 10, the captured image / video may have a perspective effect, resulting in changes in the length and width of the border.

[0041] Therefore, in order to improve the calculation accuracy of the frame, during the calculation, it is determined whether the current frame is in a perspective state according to the frame characteristics. If so, the perspective state is restored to obtain the restored frame, and then the length and width of the restored frame are calculated to determine whether it is completely recorded. In another embodiment, when the frame is in a perspective state, its perspective can be calculated, and the length / width of the complete frame on each side can be calculated according to the perspective, and the length / width is calculated with the length / width of the currently obtained frame to determine whether the induction screen 10 is completely recorded.

[0042] In the first embodiment, if it is monitored that the induction screen 10 is not completely recorded, the first rotation control instruction for the electronic police device 20 is first output, and the corresponding first rotation image / video is obtained within a preset time, for example, the preset time is any time of 10-30s, and the first rotation image / video is further used to determine whether the induction screen 10 is completely recorded. If it is still determined that the induction screen 10 is not completely recorded within the above preset time, it can be determined that the induction screen 10 does not have sufficient self-steering ability, so the corresponding second alarm information is output to prompt the management personnel to go to the site for maintenance management in time.

[0043] In the second embodiment, if it is monitored that the induction screen 10 is completely recorded, a fault identification judgment can be made immediately. However, in actual application, since the induction screen and the camera are both set in an outdoor environment, they will inevitably be affected by obstructions, such as leaves and other debris, and such obstructions will affect the display identification of the induction screen 10. In order to solve the above technical problems, after determining that the induction screen 10 is completely recorded, further obstruction identification is performed.

[0044] In an embodiment of the present invention, judging whether there is occlusion in the display area corresponding to the induction screen based on the display content characteristics includes: judging whether there is an occlusion feature in the display area based on the display content characteristics; if the occlusion feature exists, generating a second rotation control instruction for the electronic police device; acquiring a second rotation image / video corresponding to the second rotation control instruction; judging whether the occlusion feature has a position change on the induction screen based on the second rotation image / video; if the occlusion feature has a position change, outputting feedback information of occlusion of the electronic police device; if the occlusion feature has not a position change, outputting feedback information of occlusion of the induction screen.

[0045] In a possible implementation, firstly, it is determined whether there is an occlusion feature in the display area of ​​the induction screen 10 based on the extracted display content features. For example, the technicians pre-set the occlusion features including leaves, paper, sludge, advertising cloth and other debris in the database. When the display content of the induction screen 10 is identified, it is compared with the above features to determine whether there is an occlusion feature in the display area. For example, in one embodiment, it is detected that there is at least one occlusion feature in the display area of ​​the induction screen 10. In order to accurately determine whether the occlusion feature is located on the camera or on the induction screen 10, a second rotation control instruction for the electronic police device 20 is generated, and a second rotation image / video corresponding to the second rotation control instruction is obtained.

[0046] According to the second rotating image / video, it is determined whether the absolute position of the occlusion feature on the induction screen 10 has changed. If the absolute position has changed, it can be determined that the occlusion feature is caused by an obstruction on the camera, so the feedback information of the occlusion of the electronic police device 20 is output; if the absolute position has not changed, it can be determined that the occlusion feature is caused by an obstruction on the induction screen 10, so the feedback information of the occlusion of the induction screen 10 is output. For the occlusion, whether it is on the camera or on the induction screen 10, it needs to be cleared in time to ensure sufficient monitoring or prompting effect.

[0047] In the embodiment of the present invention, the actual problems faced by the induction screen 10 and the camera during the monitoring process are intelligently analyzed and determined, so that they can be accurately checked and managed to avoid the deviation of the subsequent display analysis, thereby effectively improving the accuracy of monitoring. At the same time, by separately and accurately identifying the occlusion on the induction screen 10 and the camera, the influence of the occlusion on the camera on the license plate recognition, traffic flow statistics, induction screen recognition and other aspects can be further reduced, achieving the effect of linkage optimization.

[0048] In one embodiment, it is monitored that there is no shielding feature in the display area of ​​the induction screen 10, so it is further determined whether the induction screen 10 is faulty.

[0049] In an embodiment of the present invention, judging whether the induction screen 10 is faulty based on the display content characteristics includes: determining a fixed display time period, during which the induction screen 10 has display content and the main control center 30 suspends outputting new display instructions to the induction screen 10 during the fixed display period; obtaining preset fault characteristics, which include continuous color characteristics and discontinuous color characteristics; judging whether there are abnormal characteristics matching the continuous color characteristics or the discontinuous color characteristics in the display content characteristics within the fixed display period; judging whether there are icon characteristics with sudden changes in position based on the display content characteristics within the fixed display period; if the abnormal characteristics and / or the sudden changes exist, determining that the induction screen is faulty.

[0050] In a possible implementation, in order to ensure the accuracy of the recognition of the display content of the induction screen 10, a freezing period is set, during which the content displayed on the induction screen 10 is set to fixed content, so that any abnormal features thereof can be accurately identified and captured. Specifically, a fixed display period is first determined. In an embodiment of the present invention, the fixed display period is controlled and implemented by the main control center 30. Specifically, during the fixed display period, the induction screen 10 displays the specified display content according to the display instruction, and the main control center 30 pauses outputting new display instructions to the induction screen 10, thereby achieving the fixation of the display content of the induction screen 10. On this basis, a preset fault feature is obtained, and the preset fault feature includes a continuous color feature and a discontinuous color feature.

[0051] For example, in the first embodiment, a certain induction screen 10 has a continuous display of a large area, for example, the abnormal display is caused by the failure of related electronic components. Therefore, through the above display content characteristics, it is monitored that there is a continuous color feature in the fixed display period, specifically, any value of the length and width of the continuous display pixels on the induction screen 10 exceeds the set threshold, which is considered to meet the above continuous color characteristics, so it is determined that the induction screen 10 has a fault; in the second embodiment, a certain induction screen 10 has a flower screen, that is, a random color display appears in a certain display area, and thus it is detected that there is a discontinuous color feature in the fixed display period, specifically, there are multiple colors that appear randomly in a continuous display area point, which is considered to meet the above discontinuous color characteristics, so it is determined that the induction screen 10 has a fault. In the third embodiment, due to the damage of related electronic components, a certain induction screen 10 has a situation where some content is displayed in the A sub-area of ​​the display area for a while, and then the display content in the A sub-area disappears, and other content is displayed in the B sub-area, that is, the content jump occurs. Therefore, through the above display content characteristics, a mutation feature of position mutation is monitored in the fixed display period, so it is also determined that the induction screen 10 has a fault.

[0052] Since the induction screen 10 is often only used for static and fixed display of specific text content during use, in an embodiment of the present invention, by analyzing and extracting features of the actual problems faced by the induction screen 10 during actual use, it is possible to accurately capture its various fault features and accurately locate its fault conditions, thereby achieving accurate induction screen fault analysis.

[0053] After determining whether the induction screen 10 is faulty, if it is determined that the induction screen 10 is faulty, the corresponding first alarm information is immediately output to prompt the management personnel to go to the site for repair or replacement in time. If the induction screen 10 is not faulty, its display content can be analyzed to achieve accurate monitoring of its display content. Specifically, the display content currently displayed by the induction screen 10 is identified according to the extracted display content features, and then matched with the display requirements. If the display content does not match the actual requirements, the corresponding first reminder information is immediately output.

[0054] In the embodiment of the present invention, by adopting an intelligent monitoring model, the electronic police equipment 20 is used to perform regular monitoring of the display content of the induction screen 10, thereby achieving an intelligent monitoring effect of the display content of all induction screens 10, without the need for manual one-by-one inspection or passive response, thereby effectively ensuring the display effect of the induction screen 10, improving management accuracy and effectiveness, and improving user experience.

[0055] However, in actual application, if the content displayed in the induction screen 10 does not match the expected content, it is easy to mislead the public and even cause accidents. Therefore, on the one hand, if the display content of the induction screen 10 can be corrected in time, it is necessary to correct the content in time; if it cannot be corrected in time, it is necessary to shut down its display function in time to avoid the above-mentioned accidents.

[0056] In an embodiment of the present invention, the main control center 30 is also used to: obtain the network status after outputting the first reminder information; if the network status is characterized by a network abnormality, output a third reminder information; if the network status is characterized by a normal network, generate a new display instruction based on the display requirement; determine whether the display content corresponding to the induction screen and the new display instruction matches the display requirement; if not, output a third alarm information and execute a power-off control operation for the induction screen.

[0057] In one possible implementation, when it is determined that the display content of the induction screen 10 does not match the display requirements, a first reminder message is generated to alert the management personnel. At this time, the network status is immediately obtained. If the current network status is abnormal, a third reminder message is immediately output to remind the management personnel that the display of the induction screen 10 cannot be remotely controlled and that technical personnel need to be dispatched on-site for maintenance in a timely manner. In another embodiment, if the network between the induction screen 10 and the main control center 30 is normal, a new display instruction is generated and output according to the display requirements, and further, it is determined based on the monitored image / video whether the display content of the induction screen 10 based on the new display instruction matches the display requirements. If the display content still does not match, the third alarm message is output, that is, the display content of the induction screen may be maliciously tampered with or cannot display the predetermined display content, and there is a potential risk of an accident, so the corresponding power-off control operation is immediately executed.

[0058] In the embodiment of the present invention, by characteristically analyzing and separately processing the actual problems existing in the actual use of the induction screen 10, all interference situations are effectively eliminated, and accurate and effective monitoring of the display content of the induction screen 10 is achieved, thereby ensuring the display reliability of the induction screen 10, avoiding the occurrence of display accidents, and meeting actual needs.
