Abstract

The invention provides an analysis method of an AR-based infrared detection auxiliary welding intelligent helmet device. The method comprises the steps that: (1) after a worker wears a helmet, weldingwork preparation is completed, (2) an infrared image acquisition device performs image acquisition on spot welding and transmits a collected image signal to an image acquisition card to be stored andconverted into a digital signal, (3) the digital signal transmitted by the image acquisition card is received through a portable high-performance image processing computer and is processed quickly ina short time, and then a processing result is transmitted to an adjustable AR display screen, (4) the adjustable AR display screen carries out augmented reality technical integration on the processing result and then displays the result on a screen of the adjustable AR display screen, and (5) welding quality is judged through human eyes, the rapid communication is carried out through a communication device if a defect exists, process parameters are rapidly improved, the welding is continued; if the welding has no defect, the welding is continued; and the step continues until the welding is completed.

Description

technical field [0001] The invention relates to the technical field of welding protection and auxiliary infrared detection, in particular to an analysis method of an AR-based infrared detection auxiliary welding smart helmet device. Background technique [0002] The metal welding process is accompanied by glare and defects. The strong light is harmful to our eyesight and is not conducive to observing the welding process, and cannot judge the welding quality. [0003] Welding helmets are tools used to protect the safety of workers during welding and cutting operations. Traditional welding helmets only serve: 1) Eye protection: double filtering to avoid harmful ultraviolet and infrared radiation generated by the arc, as well as damage to eyes caused by strong welding light; 2) Face protection: Effectively prevent splashes and harmful 3) Respiratory protection: Airflow guidance, effectively reducing harmful gases and dust released by welding from causing damage to the body; ...
