Embodiment Construction
[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below according to the drawings and embodiments. It should be understood that the specific implementations described here are only used to explain the present invention, not to limit the present invention.
[0024] Such as figure 1 Shown, a kind of surveillance method that can identify azimuth, comprises steps:
[0025] S100: Set multiple cameras in the same plane, and the angle between two adjacent cameras is known.
[0026] The camera can preferably use a large wide-angle camera, so as to capture a wider range of monitoring object pictures. The number of its cameras can be selected according to actual needs, assuming that N cameras evenly spaced are selected, when 360-degree all-round monitoring is required, the included angle between any two cameras is the same and is (360 degrees / N) degrees. It should be unders...

The present invention provides a monitoring method and system capable of identifying azimuths. Multiple cameras are set in the same plane, and the angle between two cameras is known. The relative azimuth relationship between multiple cameras is determined, and one camera is arbitrarily selected as Preset the reference camera, set the preset known orientation, use multiple cameras to shoot images of the surveillance object, and detect the deviation of the preset reference camera from the preset known orientation angle, according to the deviation from the preset known orientation angle, preset known orientation and the relative orientation relationship between multiple cameras to determine the current orientation of each camera. In the whole process, the orientation recognition process is simple. Multiple cameras with clear relative positions and preset known orientations are used for orientation recognition. It will not cause unstable signal transmission and orientation recognition failure due to the complex environment of the application scene, and its stability is strong. , and in addition, the whole orientation identification process is simple, and the implementation cost of orientation identification is low.
Description
technical field [0001] The invention relates to the technical field of image monitoring, in particular to a monitoring method and system capable of identifying orientations. Background technique [0002] With the development of video surveillance technology and the continuous improvement of security requirements, various surveillance devices have appeared on the market, especially surveillance devices that shoot panoramic (360° no dead angle) video. The system can be moved at will and can take a 360° comprehensive shot of the environment to be shot. It can be applied to scenes where many people are inconvenient to enter to obtain the environmental conditions inside. The video monitoring equipment is required to have the function of indicating the direction. At present, the method for realizing this function is mainly to use a dedicated electronic module such as a GPS chip, locate the current geographic coordinates through satellites, and infer the direction coordinates. Th...
