Detection device and detection method used for testing indexes such as dynamic vehicle bottom image definition of vehicle bottom restricted article security inspection system

Abstract

The invention discloses a detection device and a detection method used for testing indexes such as dynamic vehicle bottom image definition of a vehicle bottom restricted article security inspection system. According to the technical scheme, the detection device comprises a high-speed running track, a fixing tray, a vehicle bottom simulation test card support and a vehicle bottom image definition test card, wherein the high-speed running track is controlled to run at different constant speeds, the fixing tray is capable of locking various vehicle bottom image acquisition components of the tested vehicle bottom restricted article security inspection system and can move along the track at a constant speed, the vehicle bottom simulation test card support is adjustable in height and is foldable transversely, and the vehicle bottom image definition test card is composed of a plurality of aluminum ladder modules different in specification and fixed in distribution and can be mounted on the vehicle bottom simulation test card support. The detection device and the detection method have the advantages that detection of functions and performances relevant to the vehicle bottom image acquisition components can be supported, the problem of laboratory simulation test of the dynamic vehicle bottom image definition performance index is solved particularly, and the detection device and the detection method are of important significance to improvement on the product quality of the vehicle bottom restricted article security inspection system.

Description

technical field [0001] The invention relates to a detection technology for laboratory inspection and testing of technical indicators of a safety inspection system for prohibited items at the bottom of a vehicle, in particular to automatic scanning function, inductive lighting control function, image acquisition speed, image acquisition rate and dynamics in the safety inspection system for prohibited items at the bottom of a vehicle Laboratory testing devices and testing methods for indicators such as the image clarity of the vehicle bottom. Background technique [0002] Terrorism is one of the threats to national security. Since the "9.11" terrorist incident in the United States, preventing and dealing with terrorist activities has become an important issue of concern to governments and the public. It is an important aspect to prevent and deal with all kinds of explosive terrorist attacks. Especially since 2013, against the backdrop of the rebound of international terroris...
