Abstract

The invention provides a track-detection-car-verification-platform dip angle reading device based on machine vision and a method. The track-detection-car-verification-platform dip angle reading device comprises a computer provided with halcon machine vision image processing software, a camera, a secondary light source, a track-detection-car verification platform and an active amount block combination. The camera is connected with the computer through a reticle, the active amount block combination is put between an upper supporting block and a lower cushion block of the track-detection-car verification platform, and the camera is matched with the secondary light source to be right opposite to the active amount block combination. The track-detection-car-verification-platform dip angle reading device is based on the machine vision for replacing traditional artificial data reading, the objectivity and the accuracy in the verification process are effectively guaranteed, and the verification result is more scientific.

Description

technical field

[0001] The invention relates to an inclination reading device for a rail inspection trolley verification platform, in particular to a machine vision-based inclination reading device and method for a rail inspection trolley verification platform. Background technique

[0002] At present, the general track inspection trolley verification platform mainly adopts human operation to read data when verifying superelevation. Under normal circumstances, people will have discriminative errors when reading data, especially when doing some repetitive measurement test items, using the same method to complete the test work again and again, the eyes will be very tired, so every time the test will be There are subtle differences, which will lead to large errors in the test results. There is also a serious flaw in human eye testing, which is the subjectivity brought about by emotions. The test results will change with the mood of the tester, and the test results are poor in ...
