Comprehensive evaluation method and system for camera performance

Abstract

The invention provides a comprehensive evaluation method and system for camera performance. The method comprises steps as follows: at least two stages of evaluation parameters for evaluating the camera performance are determined in advance, each current-stage evaluation parameter corresponds to at least one or more next-stage evaluation parameters, and the scoring standard of each last-stage evaluation parameter is determined; first weight and second weight of each last-stage evaluation parameter are acquired respectively; comprehensive weight of each last-stage evaluation parameter is determined according to the first weight and the second weight of each last-stage evaluation parameter; a comprehensive score of the to-be-evaluated camera performance is acquired according to the comprehensive weight of each last-stage evaluation parameter and a score of each last-stage evaluation parameter of a to-be-evaluated camera. According to the method, weight of each evaluation parameter is acquired from the subjective point of view and the objective point of view, and the comprehensive weight is obtained through comprehensive consideration, so that the finally obtained result is more objective and accurate and conforms to actual conditions.

Description

technical field [0001] The invention relates to the field of system evaluation, in particular to a comprehensive evaluation method and system for camera performance. Background technique [0002] Video surveillance devices are currently widely used for a variety of purposes. In addition to the application of video surveillance devices in private, public buildings and public places to prevent unauthorized interference, theft, robbery and attacks, they are also increasingly used in Street traffic monitoring, etc., such as monitoring traffic in highways and tunnels. The camera is the front-end equipment of the video surveillance system, and its performance has an important impact on the effectiveness of the entire surveillance system. With the extensive development of social security video surveillance systems, the demand for suitable cameras is increasing. At present, there are many types of cameras on the market with different performances, and users are paying more and more...
