Problems solved by technology

The line array cameras are placed in a non-coplanar structure to increase the overlap of the field of view. At the same time, the area array camera controls the macroscopic field of view, locates the feature points, avoids the problem that the image feature points cannot be matched due to jitter, etc., and improves the disease measurement. and the accuracy of dimension measurement

specific Embodiment approach

[0057] In a specific embodiment, the pan-tilt control device 8 includes a deflection angle detection module 9, a micro-control module 10, a drive module 11 and a feedback module 12;

[0058] The deflection angle detection module 9 detects the angle change of the pan-tilt and the angle of each camera caused by the rotation or shaking of the rotating pan-tilt 2 and transmits them to the micro-control module 10 and the feedback module 12 .

[0059] The micro-control module 10 is used to receive the information sent by the deflection angle detection module 9, and the control drive module 11 passes through the first rotating bracket 13 on the first rotating platform 2 and the camera support frame 14 on the stabilizing platform 3. Angle control, and then realize the adjustment of the camera shooting posture to achieve the purpose of adjusting the shooting angle.

[0060] In specific implementation, described deflection angle detection device 9 is made up of high-sensitivity nine-axi...

Abstract

The invention belongs to the field of pipe gallery apparent disease detection, and provides a linear array binocular imaging system for pipe gallery apparent disease detection and a working method. The linear array binocular imaging system comprises: a guide rail which is laid in a pipe gallery; a first rotary holder and a second rotary holder which are both suspended on the guide rail and can move along the guide rail; an image acquisition and detection device which is mounted on the first rotary holder through a first rotary bracket, wherein the image acquisition and detection device comprises a binocular structure linear array camera and an area array camera; an auxiliary calibration device which is mounted on the second rotary holder through a second rotary bracket; and a processor which is used for receiving the pipe gallery apparent images simultaneously acquired by the binocular structure line-scan digital camera and the area-scan digital camera, identifying disease types and contours, and calibrating the disease contours through the position of the auxiliary calibration device to obtain the sizes of the diseases.

Description

technical field [0001] The invention belongs to the field of apparent disease detection of a pipe gallery, and in particular relates to a linear array binocular imaging system and a working method for detecting apparent diseases of a pipe gallery. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] Pipe gallery is an effective way to solve the layout problems of various underground pipe networks. The currently implemented urban comprehensive utility gallery mainly integrates various pipelines such as electric power, communication, radio and television, gas, water supply and drainage, and heat, and builds an integrated box culvert in the underground space of urban roads. The urban underground comprehensive pipe gallery is in the stage of rapid development, but the construction technology in China is not yet mature. During the construction, pro...
