Problems solved by technology

However, surveillance cameras, especially surveillance cameras installed outdoors, are easily affected by the external environment, such as rainy and snowy weather, windy weather, etc., which may cause changes in the placement and orientation of the camera, making it impossible to obtain the required high-definition surveillance video
[0003] At present, the maintenance of surveillance cameras mainly judges whether the camera’s position and orientation have shifted by manually checking the video effect. This inspection method is inefficient and requires a lot of manpower and material resources for one inspection. This way of checking is extremely inconvenient

Embodiment 1

[0049] see figure 2 As shown, a schematic flowchart of a method for monitoring the orientation of a surveillance camera provided by an embodiment of the present application includes the following steps:

[0050] S201. Collect a surveillance image captured by a surveillance camera, and select feature points from the surveillance image.

[0051] In this step, the control device may periodically collect the monitoring images captured by the monitoring camera, wherein the collection period may be set in advance according to actual requirements. For example, a monitoring image captured by a monitoring camera is collected every 1 minute.

[0052] After the monitoring image is collected, feature points can be selected from the monitoring image. The selected feature points can be the points where the gray value of the image changes drastically or the points expressed by the curvature on the edge of the image. For example, taking the surveillance camera as an example of a surveilla...

Embodiment 2

[0082] Embodiments of the present application provide a device for monitoring surveillance cameras, refer to image 3 As shown, a schematic structural diagram of a monitoring and surveillance camera device 300 provided by an embodiment of the present application, the device 300 includes an information collection module 301 , an orientation information determination module 302 , an information processing module 303 , and an alarm module 304 .

[0083] Specifically, the information collection module 301 is configured to collect a monitoring image captured by a monitoring camera, and select feature points from the monitoring image;

[0084] An orientation information determination module 302, configured to determine the first orientation information where the surveillance camera is located according to the image feature data of the feature point and the geographic coordinate data of the feature point;

[0085] The information processing module 303 is configured to monitor whether...

Embodiment 3

[0098] like Figure 4 As shown, a schematic structural diagram of an electronic device 400 provided in Embodiment 3 of the present application includes: a processor 401, a memory 402, and a bus 403;

[0099] The memory 402 stores machine-readable instructions executable by the processor 401 (eg, including image 3 The information acquisition module 301, the orientation information determination module 302, the information processing module 303 and the corresponding execution instructions of the alarm module 304), when the electronic device 400 is running, the processor 401 and the memory 402 communicate through the bus 403 , when the machine-readable instructions are executed by the processor 401, the following processing is performed:

[0100] collecting surveillance images captured by surveillance cameras, and selecting feature points from the surveillance images;

[0101] Determine the first orientation information where the surveillance camera is located according to the...

Abstract

The invention provides a method and a device for monitoring the orientation of a surveillance camera, wherein the method comprises the following steps of: collecting a monitoring image captured by thesurveillance camera, and selecting the feature points from the monitoring image; determining first orientation information of the surveillance camera according to the image feature data of the selected feature points and the geographic coordinate data of the feature points; monitoring whether the orientation of the surveillance camera is shifted or not by comparing the first orientation information with preset second orientation information, wherein the second orientation information is used to represent the initial orientation of the surveillance camera; and performing alarm processing whendetermining that the orientation of the surveillance camera is shifted,. In this way, the staff only needs to maintain the surveillance cameras which need to be maintained according to the alarm signals instead of manual detection one by one, and the work efficiency is improved.

Description

technical field [0001] The present invention relates to the field of computer technology, and in particular, to a method and device for monitoring the orientation of a surveillance camera. Background technique [0002] In recent years, with the increasing demand for security surveillance cameras, the security surveillance industry has developed rapidly. The application of surveillance cameras has developed from individual industries to the needs of the mass market, from local surveillance to remote surveillance across regions and provinces, from analog surveillance cameras to Internet Protocol (IP) surveillance cameras with multiple advantages. Surveillance cameras are mainly used for real-time monitoring, usually with higher pixel and resolution than ordinary cameras, and some products have functions such as anti-glare, anti-vibration or night vision. However, surveillance cameras, especially surveillance cameras installed outdoors, are easily affected by the external envi...
