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

The embodiment of the invention provides a vehicle detection rate determination method and device, and relates to the technical field of video monitoring. The method comprises: obtaining a first vehicle passing record and a second vehicle passing record, wherein the first vehicle passing record and the second vehicle passing record are respectively acquired by a first image acquisition device anda second image acquisition device which are located in the same test scene; extracting first vehicle passing data and second vehicle passing data from the first vehicle passing record and the second vehicle passing record respectively; and then determining a vehicle detection rate of the first image acquisition device and / or the second image acquisition device based on the first vehicle passing data and the second vehicle passing data. A plurality of groups of vehicle passing records are directly used for transverse comparison such that the vehicle detection rate determination process is converted into an automatic and long-term real-time monitoring method, manual detection is not needed, the labor cost and the detection time are saved, the problem that the result is inaccurate due to thefact that the number of samples is small during manual detection is solved, and the vehicle detection rate is 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...
