Description

Technical Field

[0001] This utility model relates to the field of image stitching acquisition technology, and in particular to an image stitching acquisition device. Background Technology

[0002] Image acquisition is the process of obtaining signal distribution information of an image through imaging equipment. Image stitching technology is the technique of stitching together several images with overlapping parts, which may have been obtained at different times, from different perspectives, or from different sensors, into a seamless panoramic or high-resolution image. Currently, the mainstream image acquisition tools rely on CCD or CMOS cameras to acquire images in a fixed position, that is, to acquire images at the work site, including static single images and multiple continuous scene images. In fact, an image is a projection of a three-dimensional scene onto a specific two-dimensional plane, which can replace the real scene.

[0003] In existing image stitching acquisition processes, the camera is in a fixed position. However, for larger equipment to be inspected, such as large port machinery, the length and width dimensions of the geometric shape exceed the field of view of a single camera shot, requiring the stitching and synthesis of multiple images. This necessitates moving the camera during the image stitching acquisition process. If the translation is unstable during the shooting process, it is prone to shaking, which can lead to a decrease in image quality and require post-processing. Therefore, a new image stitching acquisition device is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a stitching image acquisition device that automatically aligns points during multiple stitching image acquisitions. This solves the problem that in existing stitching image acquisition processes, the camera is in a fixed position. However, for larger equipment to be inspected, such as large port machinery, the geometric dimensions of the shape exceed the field of view of a single camera shot, requiring the stitching and synthesis of multiple images. This necessitates moving the camera during the stitching image acquisition process, which can lead to unstable translation and shake, resulting in a decrease in image quality.

[0005] In summary, this utility model provides the following technical solution: a stitched image acquisition device, including a housing, an alignment structure is provided on the top of the housing, and a power structure is provided outside the alignment structure;

[0006] The alignment structure includes an outer shell, the bottom of which is fixedly connected to the top of the housing. A first threaded rod is rotatably mounted inside the housing, with one end penetrating and extending to the outside of the outer shell. A sleeve is rotatably mounted inside the housing, with one end penetrating and extending into the housing. A transverse gear is fixedly mounted on the outer surface of the sleeve. Two second threaded rods are rotatably mounted inside the housing, each with one end penetrating and extending to the outside. Vertical gears are fixedly mounted on the outer surfaces of both second threaded rods. The outer surfaces of the transverse gears mesh with the outer surfaces of the two vertical gears. Fixed rods are fixedly mounted on the left and right sides of the housing. Vertical adjustment rods are movably mounted on the outer surfaces of the two fixed rods and the outer surfaces of the two second threaded rods, respectively. A transverse adjustment rod is threaded onto the outer surface of the first threaded rod. A mounting slider is slidably mounted on the outer surfaces of the transverse and vertical adjustment rods. A camera is fixedly mounted on the front of the mounting slider.

[0007] This invention employs the above-described technical solution, using a slider to drive the camera movement and acquire stitched images. The first and second threaded rods automatically align the points during image acquisition, resolving the displacement deviation that occurs when multiple cameras are running, resulting in better acquisition quality.

[0008] Furthermore, the power structure includes a first motor, the bottom of which is fixedly connected to the inner bottom wall of the housing. The output shaft of the first motor is fixedly connected to a rotating shaft via a coupling. A first gear is fixedly installed on the outer surface of the rotating shaft and the outer surface of the sleeve, and the outer surfaces of the two first gears mesh with each other.

A second gear is fixedly installed on the outer surface of the movable shaft and the outer surface of the first threaded rod, and the outer surfaces of the two second gears mesh with each other.

[0009] By adopting the above-mentioned technical solution, this utility model provides power to the alignment structure through the first motor and the second motor respectively, resulting in more accurate positioning, convenient operation, and suitability for widespread use.

[0010] Furthermore, the vertical adjusting rod has a threaded hole and a movable hole inside, the inner surface of the threaded hole is threadedly connected to the outer surface of the second threaded rod, and the inner surface of the movable hole is slidably connected to the outer surface of the fixed rod.

[0011] The beneficial effect of adopting the above-mentioned further solution is to improve the accuracy of the vertical adjustment rod during movement.

[0012] Furthermore, a controller is fixedly installed on the inner bottom wall of the housing.

[0014] Furthermore, the sleeve has an installation hole inside, and the inner surface of the installation hole is rotatably connected to the outer surface of the first threaded rod.

[0015] The beneficial effect of adopting the above-mentioned further solution is that the sleeve and the first threaded rod are not disturbed when they rotate.

[0016] Furthermore, the horizontal adjustment rod and the vertical adjustment rod are cross-shaped when viewed from the front.

[0017] The beneficial effect of adopting the above-mentioned further solution is that it allows for the positioning of the mounting slider.

[0018] Furthermore, the mounting slider has a first mounting hole and a second mounting hole respectively inside. The inner surface of the first mounting hole slides in contact with the outer surface of the horizontal adjusting rod, and the inner surface of the second mounting hole slides in contact with the outer surface of the vertical adjusting rod.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-3 The image stitching acquisition device in this embodiment includes a housing 1. A controller is fixedly installed on the inner bottom wall of the housing 1 to control the switching of the first motor 301 and the second motor 304. An alignment structure 2 is provided on the top of the housing 1, and a power structure 3 is provided on the outside of the alignment structure 2.

[0029] Please see Figure 1-3 In this embodiment, the upright structure 2 includes a housing 201. The bottom of the housing 201 is fixedly connected to the top of the casing 1. Two second threaded rods 205 with one end penetrating through and extending to the outside are rotatably installed inside the housing 201. Fixing rods 207 are fixedly installed on both the left and right sides of the housing 201. Vertical adjusting rods 208 are movably installed on the outer surfaces of the two fixing rods 207 and the outer surfaces of the two second threaded rods 205, respectively. The second threaded rods 205 drive the vertical adjusting rods 208 to move.

[0030] The vertical adjusting rod 208 has a threaded hole and a movable hole inside. The inner surface of the threaded hole is threaded to the outer surface of the second threaded rod 205, and the inner surface of the movable hole is slidably connected to the outer surface of the fixed rod 207, thereby enhancing the accuracy of the vertical adjusting rod 208 when it moves.

[0031] In this embodiment, a first threaded rod 202 with one end penetrating through and extending to the outside of the outer shell 201 is rotatably installed inside the housing 1. A sleeve 203 with one end penetrating through and extending into the outer shell 201 is rotatably installed inside the housing 1. A transverse gear 204 is fixedly installed on the outer surface of the sleeve 203, and the sleeve 203 drives the transverse gear 204 to rotate. Vertical gears 206 are fixedly installed on the outer surfaces of the two second threaded rods 205, driving the second threaded rods 205 to rotate. The outer surfaces of the transverse gears 204 mesh with the outer surfaces of the two vertical gears 206 respectively.

[0032] The sleeve 203 has an installation hole inside, and the inner surface of the installation hole is rotatably connected to the outer surface of the first threaded rod 202, so that the rotation of the sleeve 203 and the first threaded rod 202 is not affected.

[0033] In this embodiment, a horizontal adjusting rod 209 is threadedly installed on the outer surface of the first threaded rod 202. The first threaded rod 202 drives the horizontal adjusting rod 209 to move. The outer surface of the horizontal adjusting rod 209 and the outer surface of the vertical adjusting rod 208 are slidably mounted on a mounting slider 210. Both the horizontal adjusting rod 209 and the vertical adjusting rod 208 can adjust the position of the mounting slider 210. The horizontal adjusting rod 209 and the vertical adjusting rod 208 are cross-shaped when viewed from the front.

[0034] The mounting slider 210 has a first mounting hole and a second mounting hole inside. The inner surface of the first mounting hole slides in contact with the outer surface of the horizontal adjusting rod 209, and the inner surface of the second mounting hole slides in contact with the outer surface of the vertical adjusting rod 208, so that the horizontal adjusting rod 209 can adjust the position of the mounting slider 210 by adjusting the vertical adjusting rod 208.

[0035] The camera is fixedly mounted on the front of the mounting slider 210, and the mounting slider 210 drives the camera to move.

[0036] Specifically, the first gear 303 drives the sleeve 203 and the horizontal gear 204 to rotate, which in turn drives the two vertical gears 206 to rotate the two second threaded rods 205, which in turn drives the two vertical adjusting rods 208 to move through the fixed rod 207. The second gear 306 drives the first threaded rod 202 to rotate, which in turn drives the horizontal adjusting rod 209 to move through the two vertical adjusting rods 208. This ensures that the two mounting sliders 210 move synchronously, avoiding inaccurate point alignment during image acquisition and resulting in better acquisition effect.

[0037] Please see Figure 1 In this embodiment, the power structure 3 includes a first motor 301, which provides power to the alignment structure 2. The bottom of the first motor 301 is fixedly connected to the inner bottom wall of the housing 1, and a second motor 304 is fixedly installed on the inner bottom wall of the housing 1.

[0038] In this embodiment, the output shaft of the first motor 301 is fixedly connected to the rotating shaft 302 via a coupling. The first motor 301 drives the rotating shaft 302 to rotate. The outer surface of the rotating shaft 302 and the outer surface of the sleeve 203 are both fixedly mounted with the first gear 303. The rotating shaft 302 drives the first gear 303 to rotate, and the outer surfaces of the two first gears 303 mesh with each other.

[0039] In this embodiment, the output shaft of the second motor 304 is fixedly connected to the movable shaft 305 through a coupling. The second motor 304 drives the movable shaft 305 to rotate. The outer surface of the movable shaft 305 and the outer surface of the first threaded rod 202 are both fixedly installed with second gears 306. The movable shaft 305 drives the second gears 306 to rotate, and the outer surfaces of the two second gears 306 mesh with each other.

[0040] Specifically, the controller starts the first motor 301, which drives the rotating shaft 302 and the first gear 303 to rotate. The controller also starts the second motor 304, which drives the movable shaft 305 and the second gear 306 to rotate. This provides power to the alignment structure 2, making the alignment structure 2 more accurate in positioning, easier to operate, and suitable for widespread use.

[0041] The working principle of the above embodiments is as follows:

[0042] (1) When the spliced ​​image is acquired by the spliced ​​image acquisition device, the first motor 301 is started by the controller, which drives the rotating shaft 302 and the first gear 303 to rotate. The first gear 303 drives the sleeve 203 and the horizontal gear 204 to rotate, so that the two vertical gears 206 drive the two second threaded rods 205 to rotate, and drive the two vertical adjustment rods 208 to move through the fixed rod 207.

[0043] (2) Start the second motor 304 through the controller, drive the movable shaft 305 and the second gear 306 to rotate, drive the first threaded rod 202 to rotate through the second gear 306, so that the horizontal adjustment rod 209 moves through the two vertical adjustment rods 208, so that the two mounting sliders 210 move synchronously, avoiding the problem of inaccurate point alignment during image acquisition.
