T0 detection method and device based on image features and storage medium

Abstract

The invention provides a T0 detection method and device based on image features and a storage medium, and the method comprises the steps: carrying out the synthesis of a source video image, obtained in real time, of a detection target and a standard timestamp, and obtaining a target video image; performing specific detection area cutting on the target video image to obtain a cut video image; according to a preset rule, carrying out difference processing on the cut video image to obtain a target frame image of the detection target at T0; obtaining T0 information of the detection target according to a standard timestamp on the target frame image; and therefore, the problem that errors exist due to manual observation, judgment and reissuing of a flight test product T0 detection method in theprior art is solved, the automation level and reliability of a detection system are effectively improved, and adverse effects of development and change of product models on T0 signals are reduced.

Description

technical field [0001] The invention relates to the technical field of measurement and control, in particular to a T0 detection method, device and storage medium based on image features. Background technique [0002] In missile testing, space launch and other shooting ranges, the actions of flight test products such as ignition, ejection, ejection, and take-off are very critical timing actions, and are important event reference points for other flight timing actions; Sequential action generates a signal that identifies the action event. The take-off signal is just a real-time electrical signal with voltage changes. In order to meet the test, launch, measurement, control and post-event analysis and processing of the experimental product, the signal needs to be converted into a time data signal. , called the take-off zero-point signal (referred to as T0 information), and send it to each user equipment according to the specified encoding format and transmission protocol; T0 co...
