Abstract

The invention discloses a visual detection device and method for a pipeline inner wall, and belongs to the technical field of mechanical design. The visual detection device and method for the pipeline inner wall comprises a rotary mechanism, a first linear laser, a visual collecting mechanism and a control mechanism, wherein the control mechanism controls the rotary mechanism to rotate, a rotary shaft of the rotary mechanism is parallel with the central axis of the pipeline inner wall, and the first linear laser is arranged on the rotary mechanism, rotates along with the rotary mechanism, and projects first linear laser beams parallel with the central axis of the pipeline inner wall on the pipeline inner wall; the visual collecting mechanism collects the image of the first linear laser beams on the pipeline inner wall and the part above the pipeline inner wall and transmits the image to the control mechanism; the control mechanism obtains the irregularity conditions of the surface of the pipeline inner wall according to the deformation degree of the first linear laser beams of the transmitted image. According to the technical scheme, internal three-dimensional information is collected through rotary two-dimensional linear laser beams, and the grinding position and grinding degree are judged according to the collected information.

Description

technical field [0001] The invention belongs to the field of mechanical design and relates to a detection device, in particular to a visual detection device and method for the inner wall of a pipeline. Background technique [0002] At present, when working on the inner wall of the pipeline, there are basically two methods: one is artificial vision, through means such as lighting, to directly observe the surface conditions of the work site area at the nozzle; the other is to use an endoscope Or the remote control crawler enters the designated area and remotely checks the surface conditions through the images sent back by the camera. [0003] The main problems of these two traditional methods are: artificial direct vision is limited to the angle of view at the nozzle position, and the viewing angle is limited. At the same time, it is also limited by the poor lighting conditions of the nozzle, and it is impossible to perform lighting supplementary light in the deeper depths of ...
