Through the above-described high-definition composite image, there is an effect that an operator can easily identify a peripheral portion other than a portion adjacent to the welding light spot. That is, in the related art, since the brightness of the welding light is overwhelmingly brighter than that of the surrounding area, there has been a problem that the shape of the previously worked welding bead and the surrounding environment of the welding cannot be easily identified. Even a beginner operator can easily identify it.

Meanwhile, the first processor 150 may perform the first composite image c1 and the second composite image c2 in parallel.

Referring to FIG. 8, the first processor 150 may obtain a first intermediate composite image f1 by synthesizing a first frame d11 of a first camera and a first frame e12 of a second camera. . Also, the processor 150 may obtain a second intermediate composite image f2 by synthesizing the second frame d12 of the first camera and the second frame e13 of the second camera.

According to the present invention, the first processor 150 performs image synthesis in parallel while the first camera and the second camera capture a frame at the same speed as the speed at which the frame is photographed through the camera unit 110. Multiple composite images can be acquired

According to an embodiment of the present invention, the first processor 150 may display the synthesized image only on one side of the display unit 130 including the binocular display. For example, a composite image obtained by synthesizing an image acquired through the first camera by the method of FIG. 6A may be displayed on a display of the eyepiece display 132 corresponding to the first camera. On the other hand, the composite image synthesized by the method of FIG. 8 may be displayed on the display of the eyepiece display 132 corresponding to the second camera. Through this, there is an effect that a three-dimensional effect can be imparted by providing a welding image in which the welding light on the welding surface is corrected in an HDR method only on one of the eyepiece displays 132.

In FIGS. 5 to 8, it has been described that the photographing condition of the camera unit 110 is changed for each frame to obtain a welding site image or a welding image frame.

In this case, when the camera unit 110 is located inside the automatic shading cartridge, the welding image frame may be obtained by changing the shading degree of the automatic shading cartridge installed on the front side of the camera.

In this case, the first processor 150 maintains the same shooting conditions of the camera 110, and changes the degree of light blocking, so that the frames a11 to a13, a21, and the like in FIGS. d11 to d13, e11 to e13, etc.) can be obtained.

9 is a diagram for explaining a method of providing a welding image to a display unit according to another exemplary embodiment of the present invention.

Referring to FIG. 9, the camera unit 110 according to the embodiment may include a first camera, a second camera, and a third camera. The display unit 130 may include a first eyepiece display 132-1 and a second eyepiece display 132-2. In this case, the first camera may be a camera corresponding to the first eyepiece display 132-1, the second camera may be a camera corresponding to the second eyepiece display 132-2, and the third camera is a thermal image. It may be a detection camera.

The first eyepiece display 132-1 and the second eyepiece display 132-2 according to the embodiment may display a high-definition composite image to which an HDR technique is applied based on images acquired by the first and second cameras.

According to an embodiment, the processor 150 may obtain a thermal image synthesis image obtained by additionally synthesizing the thermal image image acquired by the third camera to the high-definition synthesis image. The first eyepiece display 132-1 and the second eyepiece display 132-2 may respectively display a thermal image synthesis image. In this case, the first eyepiece display 132-1 and the second eyepiece display 132-2 may provide visual information on the welding temperature using color.

According to an embodiment, the first eyepiece display 132-1 may display different images. For example, an image to which the HDR technique is not applied may be displayed on the first eyepiece display 132-1, and a composite image to which the HDR technique is applied may be displayed on the second eyepiece display 132-2. Even in this case, the first processor 150 may synthesize a thermal image image to each of the image to which the HDR technique is not applied and the synthesized image to which the HDR technique is applied, and the first eyepiece display 132-1 and the second eyepiece display ( 132-2) may control the display unit 130 to display on each.

10 is a diagram for describing an embodiment of displaying welding information according to another embodiment.

The first processor 150 according to the embodiment may provide feedback on a state of a welding current and/or voltage in a welding power cable based on welding information sensed from the welding torch 200. Specifically, referring to FIG. 10, the first processor 150 may provide a UI for a current state on a portion of an image screen displayed by the display unit 130. In this case, the UI may display information in a preset color using RGB.

For example, when it is detected that the current and/or voltage state of the welding torch 200 is abnormal, the welding information providing apparatus 100 according to the embodiment may display the red UI 1010 as a visual feedback for warning. In other cases, the green UI 1020 may be displayed.

The first processor 150 may provide feedback on various welding information in addition to the current state. For example, as shown in FIGS. 11A and 11B, the apparatus 100 for providing welding information may guide a UI for a welding direction of a torch through visual feedback.

Referring to FIG. 11A, the first processor 150 may display information on a welding direction as an arrow UI 1110. Specifically, the first processor 150 may display information detected by an acceleration sensor included in the welding torch 200 as a straight arrow for each welding direction and provide it to an operator.

Alternatively, referring to FIG. 11B, the first processor 150 may display information on the welding direction as a curved arrow UI 1110. Specifically, based on the information detected through the acceleration sensor included in the welding torch 200, the first processor 150 forms the previously-worked welding direction as a curved arrow and displays it through the display unit 130 Can be provided to.

However, this is only an example, and the first processor 150 includes a welding temperature, a welding slope, a welding speed, and a base material for a real-time welding operation sensed through at least one sensor 220 included in the welding torch 200. A UI corresponding thereto may be displayed on a partial area of the display unit 130 based on sensing information including a distance between welding torches and the like.

For example, upon receiving detection information on the welding temperature value, the first processor 150 may display a UI corresponding to the temperature value in various ways such as light, vibration, and message. In this case, the UI may be visual feedback displayed on the display unit 130 or on a partial area of the display, or may be audible feedback through voice.

Meanwhile, the sensing information on the temperature value may include whether or not the temperature of the mother agent exceeds a preset temperature range. In addition, the sensing information on the temperature value may include a numerical value, a grade, and a level corresponding to the temperature value of the welding surface.

If it is determined that the temperature value of the welding base material is out of a preset temperature range, the first processor 150 according to the embodiment may guide the operator to stop the work. In the case of welding outside the preset temperature range, there is a risk of quality deterioration, and thus, the operator can be guided so that the temperature value of the welding base material can be adjusted.

As another example, when the first processor 150 receives detection information on a welding speed value, the first processor 150 may display a UI corresponding to the value. In this case, the UI may be visual feedback provided to the display unit 130 or the display, or may be audible feedback through voice.

If it is determined that the welding speed of the torch is out of the normal range, the first processor 150 according to another embodiment may guide the operator to stop the work through visual feedback. In this case, the visual feedback may be to provide an icon indicating danger to a partial area of the display unit displaying the work site.

As another example, the first processor 150 may provide a UI so that a worker can easily identify a shape corresponding to a previously-worked welding bead. Specifically, when the shape of the welding bead is detected, the first processor 150 may display a high-definition composite image by overlapping the UI for the shape of the welding bead.

In this case, the shape of the welding bead may be obtained by detecting the residual temperature of the mother material after the welding operation through the thermal imaging camera included in the welding information providing apparatus 100. This is only an exemplary embodiment, and the apparatus 100 for providing welding information may obtain a shape of a welding bead through various methods.

12 is a block diagram illustrating a method of controlling the camera unit 110 and the lighting unit 112 according to the first processor 150 according to another exemplary embodiment.

The first processor 150 according to an embodiment includes the camera unit 110 and the illumination unit ( 112) can be controlled. Accordingly, the first processor 150 may provide more accurate environmental information of the welding work area to the welding worker by reflecting the degree of light detected through the sensor unit 150.

The first processor 150 according to another exemplary embodiment may be configured to adjust an output index of the lighting unit 112 to reflect at least a degree of light detected in the welding work area. The output indicator of the lighting unit 112 is to more clearly discriminate the image generated by the camera unit 110, and the output indicator of the lighting unit 112 is the sensor unit 140 and/or the sensor unit 220 ), the welding operator can more accurately obtain environmental information of the welding work area by adjusting it by the degree of light acquired by ).

According to the exemplary embodiment illustrated in FIG. 12, the first processor 150 calculates an output index of the lighting unit 112 (S11 ). The first processor 150 outputs the lighting unit 112 according to the calculated output index.

Light is sensed by the sensor unit 140 and/or the sensor unit 220 (S13), and the sensed data is transmitted to the first processor 150. The sensor unit 140 and/or the sensor unit 220 may include an illuminance sensor module, and accordingly, the degree of sensed light may be at least the illuminance of the welding work area.

The first processor 150 calculates an optical index based on the transmitted data (S14). Then, the calculated light index is compared with the output index of the lighting unit 112 described above (S15). These light indicators and output indicators correspond to indicators converted into a single unit so that the level of the sensed light and the output level of the lighting unit can be compared with each other. The degree of light and the degree of output of the lighting unit can be matched with each other in an optimal combination, which can be calculated in advance and stored as a table.

The first processor 150 may adjust the output index by reflecting the comparison result of the light index and the output index (S16). For example, when the light index is higher than the output index, the output index of the lighting unit 112 is adjusted downward to an optimal output index value matching the corresponding light index, so that an optimal lighting condition for the camera unit 110 can be achieved. . In addition, when the light index is lower than the output index, the output index of the lighting unit 112 is adjusted upward to an optimal output index value matching the corresponding light index, thereby additionally supporting a lighting environment insufficient for photographing by the camera unit 110.

Accordingly, according to an embodiment of the present invention, it is possible to obtain image information of high-definition image information through the camera unit 110 within the welding work environment, thereby allowing the welding operator to more clearly recognize the welding work environment. I can.

13 is a block diagram illustrating a state in which the first processor 150 controls the operation of the camera unit 110 and the lighting unit 112 according to another exemplary embodiment.

According to an embodiment, the sensor unit 140 and/or the sensor unit 220 may include an illuminance sensor module, and accordingly, the degree of light may correspond to illuminance data in the welding work area.

When data on the degree of light is transmitted to the first processor 150, the first processor 150 calculates a light index in the welding work area based on the data. In this case, the welding work area may be an area including a portion where welding is performed by the welding torch 200. Here, the light index may correspond to data converted to compare the above-described light intensity data with a specific threshold value and/or output data of the lighting unit, as described below.

The first processor 150 compares the optical index with a preset threshold (S23). Here, if the light index is greater than the threshold value, the first processor 150 turns off the lighting unit 112. The above-described threshold value may correspond to an illuminance value of light generated from a welding light spot as welding starts. The illuminance value of the light generated from the welding light spot may vary depending on the type of welding and/or the state of the welding. It can be a value that can be used. However, the present invention is not necessarily limited thereto, and the threshold value may be a plurality of values so as to respectively correspond to the type of welding and/or the state of the welding.

As such, when the light index is greater than the threshold value, since it indicates that welding has started, the first processor 150 turns off the illumination unit 112, so that the illumination unit 112 in photographing a portion where the welding operation is performed with the camera unit 110 ), it can be prevented from being interfered with by light. In addition, since the intensity of the welding light is very large, the light of the lighting unit 112 may become unnecessary light, and at this time, unnecessary power consumption in the lighting unit 112 can be minimized by turning off the lighting unit 112.

When the light index is less than the threshold value, it is determined that the welding operation is not performed, and the first processor 150 turns on the illumination unit 112 so that smooth photographing by the camera unit 110 can be performed.

At this time, first, the output index of the lighting unit 112 is calculated (S25), and based on this, the lighting unit 112 is outputted (S26).

The first processor 150 compares the light index and the output index again (S27). At this time, if the light index is higher than the output index, the output index of the lighting unit 112 is adjusted downward (S28) to an optimal output index value matching the corresponding light index, so that an optimal lighting condition for the camera unit 110 is achieved. Can be done. In addition, when the light index is lower than the output index, the output index of the lighting unit 112 is adjusted upward (S29) to an optimal output index value matching the corresponding light index, thereby additionally supporting the lighting environment insufficient for shooting by the camera unit 110. do.

As described above, the apparatus for providing welding information according to the present invention can provide an environment in which an optimal image can be obtained in a state in which unnecessary power waste is reduced through output adjustment of the lighting unit according to the situation.
