Detailed implementation manners

[0034] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0035] As Figure 1 , Figure 3 and Figure 5As shown in the figure, a binocular vision high-speed image intelligent acquisition device includes a workbench 1. A moving component 5 is installed at the upper end of the workbench 1, and an acquisition component 6 is installed on the moving component 5. The acquisition component 6 includes: a carrier board 601, which is fixed on the moving component 5; a servo motor 605, which is fixedly connected inside the carrier board 601 and is built-in with an angular displacement sensor to ensure the accuracy of angle adjustment; a rotating rod 604, which is fixedly connected to the output shaft of the servo motor 605; a fill light 602, which is fixedly connected to one side wall of the rotating rod 604. The fill light 602 has a built-in power supply, and the power supply method is battery pack power supply; a binocular camera 603, which is fixedly connected to one end of the rotating rod 604 and is built-in with a wireless communication module and a battery pack.

[0036] The specific operation is as follows:

[0037] During the acquisition process, the moving component 5 can drive the binocular camera 603 to automatically move within the acquisition space, thereby adjusting the acquisition position of the binocular camera 603. At the same time, the servo motor 605 drives the rotating rod 604 to rotate, thereby driving the binocular camera 603 to rotate. During the rotation process, the angular displacement sensor built in the servo motor 605 can detect the rotation angle, thereby realizing precise adjustment of the acquisition angle. The fill light 602 fills light for the binocular camera 603 to ensure the effect of the acquired image. The binocular camera 603 transmits the acquired image to the industrial control computer 3 through the wireless communication module. Wireless transmission can avoid the trouble of wiring and also avoid the situation of wiring entanglement during the adjustment process, ensuring the smooth and orderly progress of the adjustment process. At the same time, compared with monocular vision, through the binocular vision acquisition function, the three-dimensional binocular multi-view and multi-view distance acquisition of objects can be realized, and it can perform the observation and imaging of the same object in a 3D environment, as well as realize image acquisition, normalization and analysis. At the same time, it plays an important role in the directions of binocular vision feature extraction, position calculation, positioning and scene segmentation of images.

[0038] As Figure 1-2 Shown in the figure, as an implementation method, the moving component 5 includes: two groups of X-axis sliders 501, which are symmetrically and fixedly connected to the workbench 1; two groups of Y-axis sliders 502, which are symmetrically and fixedly connected to the two groups of X-axis sliders 501; a Z-axis slider 503, which is fixedly connected between the Y-axis sliders 502. The X-axis slider 501, the Y-axis slider 502 and the Z-axis slider 503 all use stepper motors as drivers.

[0039] The specific operation is as follows:

[0040] The X-axis slide 501 can drive the binocular camera 603 to move along the X-axis direction, the Y-axis slide 502 can drive the binocular camera 603 to move along the Y-axis direction, and the Z-axis slide 503 can drive the binocular camera 603 to move along the Z-axis direction. The combination of the three can freely adjust and position the binocular camera 603 in the acquisition space. At the same time, using a stepper motor as a driver can ensure the accuracy of adjusting and positioning the binocular camera 603.

[0041] As Figure 1 and Figure 4 shown, as an implementation method: an electric control mechanism 4 is installed on one side wall of the workbench 1. The electric control mechanism 4 includes: an electric control box 401, which is fixedly connected to one side wall of the workbench 1; a digital power supply 403, which is fixedly connected to the inner wall of the electric control box 401; a drive controller 402, which is fixedly connected to the inner wall of the electric control box 401 and is electrically connected to the digital power supply 403; the drive controller 402 and the digital power supply 403 are respectively electrically connected to the X-axis slide 501, the Y-axis slide 502, and the Z-axis slide 503.

[0042] The specific operation is as follows:

[0043] The combination of the digital power supply 403 and the drive controller 402 can control the X-axis slide 501, the Y-axis slide 502, and the Z-axis slide 503, and then realize the adjustment of the position of the binocular camera 603 in the acquisition space.

[0044] As Figure 1 - Figure 2 shown, as an implementation method; a bracket 2 is fixedly connected to one side of the upper end of the workbench 1, an industrial personal computer 3 is fixedly connected to one side wall of the bracket 2, the industrial personal computer 3 is built-in with acquisition software, the display screen of the industrial personal computer 3 is a touch display screen, and the industrial personal computer 3 is electrically connected to the drive controller 402.

[0045] The specific operation is as follows:

[0046] The industrial personal computer 3 controls the overall operation of the device. The images collected by the binocular camera 603 are transmitted into the industrial personal computer 3 and displayed through the display screen of the industrial personal computer 3 after being processed by the built-in acquisition software.

[0047] In summary, the working principle of the binocular vision high-speed image intelligent acquisition device is as follows: First, place the object whose image needs to be acquired on the workbench 1, and then control the device through the industrial control computer 3. At this time, control the X-axis slide 501, Y-axis slide 502, and Z-axis slide 503 through the digital power supply 403 and the drive controller 402. As a result, the X-axis slide 501 can drive the binocular camera 603 to move along the X-axis direction, the Y-axis slide 502 can drive the binocular camera 603 to move along the Y-axis direction, and the Z-axis slide 503 can drive the binocular camera 603 to move along the Z-axis direction. The combination of the three can freely adjust and position the binocular camera 603 in the acquisition space. After the positioning is completed, the servo motor 605 drives the rotating rod 604 to rotate, and then drives the binocular camera 603 to rotate. During the rotation process, the angular displacement sensor built in the servo motor 605 can detect the rotation angle, so as to realize the precise adjustment of the acquisition angle. The fill light 602 fills light for the binocular camera 603 to ensure the image acquisition effect. Then, the binocular camera 603 acquires the image of the object and transmits the acquired image to the industrial control computer 3 through the wireless communication module. Using wireless transmission can avoid the trouble of wiring and also avoid the situation of wiring entanglement during the adjustment process, ensuring the smooth and orderly progress of the adjustment process. After being processed by the built-in acquisition software, it is displayed on the display screen of the industrial control computer 3. Compared with monocular vision, the present application can realize the acquisition of three-dimensional binocular multi-view and multi-view distance of an object through the binocular vision acquisition function, and can perform the observation and imaging of the same object in a 3D environment, as well as realize image acquisition, normalization and analysis. At the same time, it plays an important role in the directions of binocular vision feature extraction, position calculation, positioning and scene segmentation of images.
