Description

Multi-image-sensor AR acquisition display device
Technical Field
The invention relates to the technical field of image processing, in particular to a multi-image-sensor AR acquisition display device.
Background
In the electric welding process, in order to avoid harmful radiation of ultraviolet rays and infrared rays generated by electric arcs and damage of welding strong light to eyes, various electric welding protective masks are produced to meet market demands, wherein the light-operated electric welding protective mask is the most advanced electric welding protective mask in the current market. However, the change of the light transmittance of the light-operated welding mask requires time, so that the action of the arc light at the moment of arc striking cannot be completely avoided, but the radiation intensity reaches a maximum value at the moment of arc striking, so that the welding arc light still causes damage to human eyes.
During welding operation, welding arc light harmful to human body is generated. The arc light mainly includes infrared ray, visible ray, ultraviolet ray and electromagnetic radiation. The infrared rays of the welding arc are primarily responsible for the thermal effects of the tissue. The eyes can feel strong burning and burning pain immediately after being subjected to strong infrared radiation, chronic injury can be caused to the eyes after long-term contact, and after the eyes absorb excessive infrared rays for a long time, the elasticity of the eyes is deteriorated, the accommodation is difficult, the vision is degraded, and retina burning can be caused. The luminosity of visible rays of the welding arc is ten thousand times greater than that of rays normally born by human eyes, the retina is burned to cause glaring retinitis, and the retina feels pain, is blurred and has a central dark spot and can be recovered after a period of time; if the medicine is repeatedly used for a long time, the vision is gradually reduced. Excessive uv exposure to the welding arc causes acute keratitis of the eye, known as electro-optic ophthalmia, a specialized occupational eye disease of the welder.
In order to avoid the harmful radiation of ultraviolet and infrared rays generated by electric arc and the damage of strong welding light to eyes, various electric welding protective masks have been developed to meet the market demand, such as a hand-held electric welding mask with patent number CN207871052U, which uses a common black glass sheet as a lens group and is low in cost, but has a series of problems. The hand-held welding mask does not have the automatic light changing function, an electric welder has to remove the welding mask to start an arc, but the eyes are easily damaged due to the fact that the electric welder touches harmful welding arc light with naked eyes, and the hand-held mask occupies one hand of the electric welder, so that when the hand is needed to fix a welding part, the operation is inconvenient. In addition, the welding mask only has one shading number and is difficult to adapt to different welding requirements. The light-controlled electric welding mask is the most advanced electric welding mask in the market, for example, an automatic light-changing electric welding mask with the patent number of CN207627484U, but the change process of the light transmittance of the light-controlled electric welding mask needs time, so the effect of arc light at the moment of arc striking can not be completely avoided, but the radiation intensity reaches the maximum value at the moment of arc striking, so the electric welding arc light still causes harm to human eyes. And a large amount of infrared, ultraviolet and electromagnetic radiation passes through the mask and the liquid crystal light-changing glass to cause damage to human eyes and skin, and the unstable intensity of arc light during arc striking and spot welding operations can cause the continuous change of the color number of the light-controlled electric welding mask, so that electric welders can not clearly observe electric welding working conditions and the eyes are damaged by electric welding arc light.
In conclusion, the existing electric welding protective mask in the market can not completely block harmful arc light, realize positioning, smooth transition of strip transportation and accurate spot welding.

The double-camera three-dimensional image acquisition and display can protect the face and eyes of the observation staff from being damaged by harmful rays.
In practical application, the device is applied to glasses, goggles, telescopes, microscopes and surveillance cameras, and the faces and eyes of observation workers are protected from being damaged by harmful rays through the three-dimensional image acquisition and display of the double cameras.
The dose of external harmful rays is greatly reduced after the external harmful rays pass through the box body outer shell layer and the radiation-proof shielding layer 11 of the equipment fixing mechanism 1, an observer is actually hidden behind the protective layer and observes images of a display screen through a lens, the harmful rays are prevented from penetrating through protective glasses and a variable-light electric welding mask to damage human eyes and skin, and the dose of harmful radiation is reduced to N orders of magnitude of the dose of the originally adopted protective glasses (such as laser goggles and electric welding masks).

Application example: in the process of high-power optical fiber laser welding, the infrared radiation of a molten pool contains rich welding quality information. The human eyes can not observe non-visible light images, the invention can simultaneously collect visible light images and infrared laser images for observation, or transmit the fused images to automatic welding processing control equipment, and a near-infrared high-speed camera is used for acquiring dynamic thermal images of a welding pool by taking a high-power optical fiber laser butt welding 304 stainless steel plate as a test object. Defining and extracting the width of a molten pool, the area of a key hole, the perimeter of the key hole and the centroid horizontal and vertical coordinates of the key hole to serve as characteristic parameters of the molten pool, establishing a regression model of the characteristic parameters of the molten pool and the width of a weld joint by using a support vector machine, and optimizing the parameters of the support vector machine through grid optimization and a particle swarm algorithm. Tests show that the established support vector regression machine can better fuse the characteristics of the molten pool and predict the width of a weld joint, thereby greatly improving the quality of automatically monitoring the laser welding of the high-power optical fiber.
