Problems solved by technology
However, the results of this analysis method may be wrong. For example, for a key area, multiple cameras are usually deployed at the same time to achieve full coverage of the area. Users monitor the area through camera groups. Frequently check the surveillance video of this camera group, but the frequency of operation may not be high for a single camera
At this time, if the above-mentioned method of counting the operation frequency of a single camera is used, the result of the low utilization rate of this group of cameras will be obtained, and the analysis result is not in line with the actual situation.

Embodiment Construction
[0024] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present application as recited in the appended claims.
[0025] The present application provides a method for analyzing the rationality of camera distribution, which can be used to evaluate whether the camera distribution within a preset spatial range is reasonable.
[0026] For example, the preset spatial range can be the Binjiang area of Hangzhou, then this method can be used to evaluate whether the distribution of surveillance cameras ins...

The application provides a camera distribution rationality analysis method and apparatus. The method comprises: according to camera distribution position data of a preset space range, obtaining a monitoring intensity matrix of the preset space range, wherein the monitoring intensity matrix is used for representing camera monitoring intensities of different space positions; according to camera operation log data of the preset space range, obtaining an operation intensity matrix of the preset space range, wherein the operation intensity matrix is used for representing camera operation intensities of different space positions; and calculating related coefficients of the monitoring intensity matrix and the operation intensity matrix, and according to the related coefficients, analyzing camera distribution rationality of the preset space range. According to the camera distribution rationality analysis method and apparatus, the accuracy of camera distribution rationality analysis is improved.
Description
technical field [0001] The present application relates to monitoring technology, in particular to a method and device for analyzing the rationality of camera distribution. Background technique [0002] At present, video surveillance has been widely used in the daily management of cities. Each monitoring point is of great significance for public security prevention and control, criminal investigation and case solving, and the reasonable layout of surveillance cameras used in surveillance is also very important for surveillance. For example, in the layout of monitoring points, because the actual situation of the area is not considered, the cameras are not enough in the high-frequency areas of video calls, but the cameras with the same strength are arranged in some non-critical areas, which leads to a waste of resources to a certain extent. , but the key areas are poorly monitored due to insufficient camera placement. [0003] In related technologies, for the analysis of the r...
