Description

Technical Field

[0001] The present invention relates to the field of smart city management, and in particular to a smart city traffic information service system. Background Art

[0002] Traffic management is an important part of smart city management. With the continuous emergence and application of new security technologies for intelligent transportation systems, the emergence of new technologies has a strong focus on the field of highways. For example, 5G wireless transmission is a unique way to deal with the harsh climate and geographical environment of highways. Mobile wireless monitoring of highways is generally used in a certain section of the highway. Patrol cars can transmit the video situation during patrol back to the highway management center in real time, which enhances the real-time management of intelligent transportation systems. In addition, the application of other new technologies has also provided further support for the efficiency of system management to a greater extent.

[0003] Highways are an important application site for intelligent transportation systems. Highways, referred to as highways, refer to roads that are designed for high-speed driving of cars. Highways have different regulations in different countries, regions, eras, and scientific research and academic fields. The entrances of highways are key monitoring areas of particular concern. However, some image processing, such as the application of statistical sorting filters, can easily cause the final output monitoring image to deviate from the real scene, making it difficult for the monitoring end to control and restore the real scene of the entrances of highways. Summary of the invention

[0004] In order to solve the technical problems in the related fields, the present invention provides a smart city traffic information service system, which performs image filtering processing of statistical sorting filtering on the BAYER image directly output by the image sensor of the entrance monitoring mechanism to obtain a corresponding comparison reference image, performs difference processing of each component value of two pixel points at the same coordinate position on the entrance image and the comparison reference image, and determines whether the entrance image has undergone image filtering processing of statistical sorting filtering based on the result data of the difference processing of each component value, thereby performing targeted identification of the image filtering processing of the entrance image, and providing an important basis for the monitoring end to identify the content of the entrance image. Specifically, the entrance image and the comparison reference image perform difference processing of the Y component values ​​of two pixel points at the same coordinate position to obtain multiple Y component value differences, and the arithmetic mean value processing of the remaining Y component value differences after removing the maximum value and the minimum value of the multiple Y component value differences is performed to obtain a first reference mean value, and the entrance image and the comparison reference image perform difference processing of the U component values ​​of two pixel points at the same coordinate position to obtain multiple U component value differences, and the multiple U component value differences are removed. The arithmetic mean of the remaining U component value differences after the maximum and minimum values ​​is processed to obtain a second reference mean value, the difference of the V component values ​​of two pixel points at the same coordinate position of the passage entrance image and the comparison reference image is processed to obtain multiple V component value differences, and the arithmetic mean of the remaining V component value differences after removing the maximum and minimum values ​​of the multiple V component value differences is processed to obtain a third reference mean value. When the first reference mean, the second reference mean and the third reference mean are all less than or equal to the set mean threshold value, it is determined that the passage entrance image has been subjected to image filtering processing after statistical sorting filtering. Otherwise, it is determined that the entrance image has not undergone image filtering processing by statistical sorting filtering. An entrance monitoring mechanism arranged near the ETC device of the highway is also introduced, which is used to collect image data for the entrance of the highway controlled by the ETC device when receiving a traffic detection signal, so as to obtain and input the corresponding entrance image. A linkage control mechanism is introduced to send a traffic detection signal to the entrance monitoring mechanism when the ETC device senses that a vehicle enters the entrance of the highway controlled by it, thereby reducing unnecessary false operations of the entrance monitoring mechanism and saving power consumption and computing costs at the monitoring site.
