Embodiment Construction

[0019] The present invention is described in further detail below by accompanying drawing:

[0020] Figure 1 is a schematic diagram of video augmented reality. The real-world images are captured by two cameras installed on the user's helmet, and the computer calculates and processes these images, superimposes the information to be added on the video signal of the camera, and realizes the alignment of the virtual scene and the real scene through video signal fusion , and finally presented to the user through a display system similar to a virtual reality immersive head-mounted display. Since the user's eyes do not directly see the real world, the position and direction of the camera represent the position and line-of-sight direction of the user's head.

[0021] Figure 2 is a sketch of the helmet structure. It consists of a welding protective helmet 1, a camera 2, a helmet display 3, video input and output devices 6, 7, a portable computer 5, protective glass 4, a fan, a microp...

Abstract

The present invention provides a welding protection helmet with video frequency augmented reality auxiliary operation. The helmet comprises the welding protection helmet, a binocular high dynamic range video camera, a helmet display, a video frequency input-output device, a potable computer, a protective glass, a fan, a mike, a microphone and a respiration device. With the present invention, welding is carried out by observing the video frequency of the helmet display, which avoids the harm caused by watching welding directly or indirectly. At the same time, in the present invention, the augmented reality technology is adopted, which can decrease the welder visual information insufficiency caused by various interferences produced by welding, and additional auxiliary information which is required for welding can also be added into welding at real time to guide welding. The present invention can be applied to the aspects of manual welding, mechanical welding with human participation, etc. and can also be applied to the mechanical processing and manufacturing aspects of cutting, polishing, etc.

Description

Technical field: [0001] The invention belongs to the field of electric welding protection, and more specifically relates to a welding protective helmet with auxiliary operations. Background technique: [0002] In the more than one hundred years since the advent of electric welding machines, almost all researches on welding have focused on welding machines. However, welding masks, which are necessary for the protection of electric welding operators and have a greater impact on welding quality, have been ignored by people all the time. There are few researches in this respect, and there is no breakthrough in technology. So until today, while welding is becoming intelligent, automated, and robotic, traditional protective masks in the 1920s are still commonly used. The traditional protective mask is based on the principle of color change and light change. The optical, electrical and magnetic signals generated during welding trigger the light valve of the protective sheet of the...
