And carrying out angle conversion on the video terminal according to the offset angle information so as to adjust the shooting angle, so that the patrol image shot by the video terminal can cover the whole target to be patrolled.
It can be understood that, in the association mapping relationship established between the object to be patrolled and the video terminal, one video terminal corresponds to a plurality of objects to be patrolled. The angle conversion and the multiple adjustment are carried out on the video terminal, so that one video terminal can shoot at least three objects to be patrolled, and corresponding patrolling images are obtained.
For example, in the process of executing a patrol task, a related video terminal is called according to a preset patrol flow, the video terminal automatically rotates and positions according to the offset angle information, and automatically focuses and shoots according to the zoom parameter adjusting multiple, so that the automatic patrol of the video terminal is realized.
In some embodiments, the video terminal comprises a CCD imaging terminal and an infrared thermal imaging terminal, and the real-time state comprises a structural state and a temperature state; step S400, obtaining the real-time state of the target to be patrolled according to the patrolling image, comprising the following steps: step S410, carrying out gray level conversion on the patrol image and obtaining a gray level image; step S420, carrying out normalization processing and feature extraction on the gray level image, and obtaining the image features of the target to be patrolled from the patrolling image; step S430, obtaining the structural state of the target to be patrolled according to the image characteristics; or, step S440, performing non-uniformity calibration and image enhancement on the inspection image, and extracting temperature information in the inspection image to obtain the temperature state of the object to be inspected. The CCD imaging terminal is used for acquiring visible light images, and the infrared thermal imaging terminal is used for acquiring thermal images.
When the video terminal is a CCD imaging terminal, the patrol image is a visible light image, and the patrol image is subjected to gray level conversion to obtain a gray level image; and carrying out normalization processing and feature extraction on the gray level image, obtaining the image features of the target to be patrolled from the patrolling image, and obtaining the structural state of the target to be patrolled according to the image features. The structural state may be used to indicate whether the current structure of the object to be patrolled meets a preset criterion. E.g. whether the parts are deformed, assembled in place.

And the thermal image obtained by the infrared thermal imaging terminal is used for judging whether the target to be patrolled has overheating abnormity. The mode of judging whether the target to be patrolled is overheated abnormally or not can be used for carrying out image processing on the thermal image through an infrared temperature measurement algorithm so as to carry out temperature identification and temperature difference comparison on the target to be patrolled.
After all video terminals finish shooting according to the requirement of patrol operation, a system records all patrol results and judges whether the equipment is abnormal or not by combining an intelligent identification algorithm, and a high-definition visible light camera mainly combines an image identification algorithm of equipment appearance, such as identification algorithms of appearance damage, oil leakage, corrosion, foreign matter and the like, to judge whether the equipment is abnormal or not; the infrared camera is mainly combined with an infrared temperature measurement algorithm, so that temperature identification and temperature difference comparison of equipment are realized, and whether overheating abnormity exists or not is judged.
Further, the video terminal may further include: and the meter camera is used for shooting patrol images of the target to be patrolled of the meters. And performing meter identification image processing on the obtained patrol image to obtain the reading of meters such as a pressure meter and the like and perform threshold judgment to judge whether parameters such as the air pressure value of the target equipment to be patrolled are abnormal.
In addition, a dehumidifier is arranged on a target to be patrolled of box equipment, the dehumidifier detects the temperature and the humidity inside the target to be patrolled in real time, and judges whether the temperature value and the humidity value in the box are abnormal or not. And when the humidity value exceeds the standard, dehumidifying the to-be-patrolled target by a dehumidifier.
When the scene corresponding to the target to be patrolled is the transformer substation, the video terminal patrolling method combines the target to be patrolled in the transformer substation and the three-dimensional space position parameters and the capacity parameters of each video terminal to realize automatic finding, zooming and shooting of the video terminal on equipment and equipment components according to the visual capacity range of the video terminal. Because a video terminal can automatically patrol a plurality of objects to be patrolled, the video shooting presetting bits are not required to be configured for each object to be patrolled one by one, the operation and maintenance cost can be greatly reduced, the limitation of the number of the presetting bits of the video terminal is avoided, and meanwhile, the method has higher equipment positioning accuracy and higher flexibility.
