Problems solved by technology

[0005] Although there are currently some pipeline cleaning equipment that can enter the pipeline to work, there is no technical inspiration to enable it to have image acquisition and 3D modeling capabilities
And these devices usually require extra power, need to drag cables into or frequent charging, very inconvenient to use
And once the power fails, it will not be able to travel, and the pipeline will be blocked

Embodiment 1

[0038] In order to solve the above technical problems, an embodiment of the present invention provides a three-dimensional acquisition device for the inner wall of a pipeline, also known as a three-dimensional acquisition robot (referred to as a robot in the present invention), including a body 1, an impeller 2, and a traveling unit.

[0039] The body 1 includes a rotating device 3, which may be a hollow rotating disk. The rotating device 3 is provided with one or more image acquisition ports 4 along the circumference, which are used to receive the image light of the inner wall of the target pipeline. The port may be a hole with a transparent material, or may include an optical system capable of shaping a light beam, such as a lens or a lens group, to form a light entrance. A plurality of light sources are arranged around the port. The light source can be an LED lamp bead, but an intelligent light source can also be set, for example, different light source brightness, on and ...

Abstract

The invention provides three-dimensional collection equipment for the inner wall of a pipe. The equipment comprises an equipment body and an impeller. The equipment body comprises a rotation device, an image collection port and a light deflection system. The rotation device is provided with the image collection port. The image collection port is used for guiding a pipe inner wall image into the light deflection system. The light deflection system is used for deflecting an image entering the image collection port into an image collection device. The movement speed of a scanning device, the rotation angle speed of the rotation device and the field angle of the image collection device meet the relation of a formula. It is put forward for the first time that three-dimensional collection equipment with additional power is not needed. The burden caused by driving a camera to rotate is prevented. Just by rotating the image collection port, different images are reflected into the camera through a reflector, the camera does not need to be rotated, the equipment is lower in weight, and rotation and collection are more stable.

Description

technical field [0001] The invention relates to the technical field of profile measurement, in particular to the technical field of profile measurement of the inner wall of a pipeline. Background technique [0002] Pipeline inspection usually includes electromagnetic methods and ultrasonic methods. These methods can detect defects and cracks in the pipe wall, but they cannot detect the shape of the inner wall of the pipe, especially the visual image of the inner wall of the pipe cannot be obtained intuitively. [0003] At present, there is also a method of visual inspection of the inner wall of the pipeline using a camera, but this method is limited to two-dimensional images, but for closed pipelines, it is impossible to judge the three-dimensional shape of the inner wall, so that it is impossible to accurately measure / detect the condition of the pipeline. Although the three-dimensional shape of the pipeline can be obtained by laser scanning or structured light scanning, it ...
