Adapter on-line detection system based on surface structured light

Abstract

The invention discloses an adapter on-line detection system, comprising two DLP (Digital Light Processing) projectors, four CCD cameras, an image acquisition card and a computer, wherein models of the DLP projectors and models of the cameras are the same; an angle between a light spindle of a CCD camera in each subsystem and a light spindle of a DLP projector is between 20 DEG and 60 DEG, and a relative position between the DLP projector and the CCD camera is not changed in measurement; the computer is provided with a figure video card based on a calculating unified equipment framework. A clock synchronous controller is respectively in connection with the DLP projectors and the CCD cameras to trigger the cameras and the projector to synchronously collect raster image deformed after modulation; the DLP projectors is in connection with the computer; the four CCD cameras are all in connection with the computer through the image acquisition card. The adapter on-line detection system has the outstanding characteristics of high measuring efficiency and accurate abrasion loss assessment.

Description

technical field [0001] The invention belongs to the field of precision measurement, and in particular relates to a three-dimensional measurement system for a bearing saddle in railway detection, which can perform real-time on-line quality detection on the bearing saddle installed between the train rolling bearing and the pedestal frame of the bogie side frame. Background technique [0002] With the successive operation of intercity railways and high-speed railways, my country's railways have entered a new era of high-speed railways, which also means that my country's railway safety transportation production is facing new and higher requirements. In order to ensure the safe, reliable and punctual operation of high-speed and heavy-duty trains, it is imperative to increase the application of high-tech and reform the transportation organization and its equipment maintenance methods and means. The high-speed and heavy-duty of modern railways have put forward higher requirements f...

AI Technical Summary

Problems solved by technology

At present, manual sample measurement and mechanical inspection are generally used for bearing saddle inspection. It is difficult to guarantee the measurement accuracy when testing a large number of bearing saddles, and the work efficiency is relatively low; handwritten records are not convenient for long-term storage and query; manual cooperation is required during the measurement process Moving, classification is required after measurement, labor-intensive

In addition, there are large differences in the shape and size of the various bearing saddles and the dimensions of the maintenance parts, and the measurement benchmark is not easy to determine, which brings considerable difficulty to the bearing saddle inspection.
