Problems solved by technology

[0003] In the existing technology, the vehicle detection rate is all evaluated by manual statistics, but limited by the manual statistics that need to analyze and check the test video material second by second, the manpower investment is too large; therefore, the number of samples for the test is small and affected by the environmental factors at that time. The obtained vehicle index statistics will also fluctuate

Abstract

Embodiments of the present invention provide a method and device for determining a vehicle detection rate, which relate to the technical field of video surveillance. The method and the device acquire the first passing record and the second passing record, wherein the first passing record and the second passing record are respectively obtained by the first image acquisition device and the second image acquisition device located in the same test scene collect, and extract the first passing data and the second passing data respectively from the first passing record and the second passing record, and then determine the first image acquisition device and the second passing data based on the first passing data and the second passing data / or the vehicle detection rate of the second image acquisition device; since multiple groups of passing records are directly used for horizontal comparison, the determination process of the vehicle detection rate is transformed into an automatic and long-term real-time monitoring method, without manual detection, which saves Labor cost, detection time, and the problem of inaccurate results caused by the small sample base during manual detection are avoided, making the vehicle detection rate more accurate and stable.

Description

technical field [0001] The invention relates to the technical field of video surveillance, in particular to a method and device for determining a vehicle detection rate. Background technique [0002] With the increase of motor vehicles on the road, the difficulty of traffic control is also getting higher and higher. As one of the main functions of video surveillance technology, road monitoring has been widely used, and the vehicle detection rate is a key indicator used to evaluate the road monitoring function of cameras. [0003] In the existing technology, the vehicle detection rate is all evaluated by manual statistics, but limited by the manual statistics that need to analyze and check the test video material second by second, the manpower investment is too large; therefore, the number of samples for the test is small and affected by the environmental factors at that time. The obtained vehicle index statistics will also fluctuate. Contents of the invention [0004] In...
