Description

Technical Field

[0001] The utility model relates to the technical field of pipeline detection, in particular to a panoramic lens component and a pipeline detection system. Background Art

[0002] In the field of lens imaging technology, the imaging angle range of most lenses is relatively small, usually only about 100 degrees. With the development of technology, this is far from meeting the actual needs, especially in some surveying fields. In order to obtain the surveyed images more clearly, ordinary lenses must be used to rotate the lens angle continuously so as to obtain the panoramic images within the surveyed range in an all-round way. This is very troublesome, and the clarity of the acquired images will be affected during the lens rotation process. Therefore, it is necessary to develop a panoramic lens that can obtain images within a larger viewing angle.

[0003] At the same time, when conducting pipeline inspection, the situation inside the pipeline is complicated. When the robot moves in the pipeline, the lens installed on the machine is prone to shaking and the imaging is unstable. Utility Model Content

[0004] The purpose of the present invention is to solve at least one of the above technical deficiencies.

[0005] Therefore, one purpose of the present invention is to provide a panoramic lens assembly and a pipeline detection system to solve the problems mentioned in the background technology and overcome the deficiencies in the prior art.

[0006] In order to achieve the above-mentioned object, an embodiment of one aspect of the utility model provides a panoramic lens assembly, including a fisheye lens and a lens chamber, wherein the fisheye lens is embedded in the lens chamber, the fisheye lens protrudes from the lens chamber, and a plurality of fill lights are fixedly connected to the surface of the lens chamber;

[0007] The back of the lens chamber is fixedly connected with a lens seat, and the end of the lens seat is detachably connected with a mounting seat;

[0008] The bottom of the mounting seat is fixedly connected with a support arm, both sides of the bottom end of the support arm are movably connected with joints, and one side of the joint is fixedly connected with a joint seat.

[0009] Preferably, any of the above solutions includes the fisheye lens comprising a plurality of lenses, and the fill lights are located on both sides of the fisheye lens.

[0010] Adopting the above technical solution: This device is specially used in the field of pipeline detection. Specifically, the AGV trolley and the panoramic lens assembly are lowered into the pipeline. The AGV trolley moves, and the fisheye lens takes the image inside the pipeline and transmits it to the image system of the control host.

[0011] Preferably, any of the above schemes has a shooting angle of the fisheye lens of 180 degrees, and the lens mount is threadedly connected to the mounting seat.

[0012] The above technical solution is adopted: the conventional rotating lens is abandoned, and a panoramic fisheye lens is used to shoot the internal image of the pipeline. The working principle is as follows: the fisheye lens is usually designed with a combination of multiple lenses to optimize light collection and image quality. These lenses are designed with a specific arrangement and curvature so that the light can produce an effect similar to that of a fish eye observing things on the water surface in the water after passing through the lens group. This visual effect is similar to the angle of view of a fish eye when observing close to the water surface, which can reach a wide angle of nearly 100 degrees. Secondly, the front lens of the fisheye lens is very short in diameter and bulges toward the front of the lens in a parabolic shape. This design is to enable the lens to achieve the maximum photographic angle of view. Fisheye lenses usually have a large aperture and a short focal length, which makes them have a small field angle. Therefore, in the picture taken by the fisheye lens, except for the straight line passing through the center part, which remains straight, the straight lines in other parts become curved. This imaging characteristic enables the fisheye lens to produce a very wide field of view. Image information within the angle of view range of degrees can be obtained without rotation, which is very convenient and practical.

[0013] Preferably, the mounting base, the support arm, the joint and the joint base form an anti-shake pan / tilt mechanism. The joint base has a sensor and a motor built therein, wherein the motor drives the support arm to rotate.

[0014] The above technical solution is adopted: the fisheye lens is installed on the mounting seat through the lens seat, and the joint seat is installed on the top surface of the AGV. When the lens vibrates, the sensor inside the joint seat will sense the frequency and amplitude of the vibration and transmit this information to the motor. The motor fine-tunes the angle of the arm and the lens according to the information of the sensor, and offsets the vibration of the lens by fine-tuning the angle of the arm, thereby maintaining the stability of the image and achieving the anti-shake effect, so as to ensure the stability of the output image in the complex pipeline environment.

[0015] A pipeline inspection system includes the above-mentioned panoramic lens assembly and an AGV trolley, wherein the top of the AGV trolley is detachably connected to a connector seat, an input end of the AGV trolley is fixedly connected to a cable, the cable is wound on a reel, an end of the cable is fixedly connected to a control host, and the input end of the control host is connected to a power supply system.

[0016] The top of the AGV trolley is connected to the joint seat by means of a hexagon socket bolt, wherein the hexagon socket bolt is threadedly connected to the top surface of the AGV trolley, and the hexagon socket bolt passes through the joint seat.

[0017] Compared with the prior art, the advantages and beneficial effects of the utility model are:

[0018] 1. The panoramic lens assembly and pipeline inspection system, through the coordinated arrangement of fisheye lens, lens chamber, lens holder, mounting seat, support arm, joint and joint seat, abandon the use of conventional rotating lens, and use a panoramic fisheye lens to shoot the internal image of the pipeline. The fisheye lens usually adopts a combination of multiple lenses to optimize light collection and image quality. These lenses are designed with specific arrangement and curvature, so that the light can produce an effect similar to the fish eye observing things on the water surface in the water after passing through the lens group. The fisheye lens can produce a very wide field of view. Image information within the viewing angle range can be obtained without rotation, which is very convenient and practical.

[0019] 2. The panoramic lens assembly and pipeline inspection system, the fisheye lens is installed on the mounting seat through the lens seat, and the joint seat is installed on the top surface of the AGV. When the lens vibrates, the sensor inside the joint seat will sense the frequency and amplitude of the vibration and transmit this information to the motor. The motor fine-tunes the angle of the arm and the lens according to the information of the sensor, and offsets the vibration of the lens by fine-tuning the angle of the arm, thereby maintaining the stability of the image and achieving the anti-shake effect, so as to ensure the stability of the output image in the complex pipeline environment.
