Abstract

The invention discloses an automatic vehicle body measuring device based on visual tracking, and relates to the technical field of railway passenger vehicle body measurement. The automatic vehicle body measuring device comprises a high-precision binocular vision measuring system, a guide rail movement control system, a photogrammetry camera tracking system and a robot. The technical problems of poor measurement precision, low efficiency and high cost in the prior art are solved, low-cost automatic precision measurement is realized, measurement data are automatically stored, and an electronic detection report can be generated.

Description

technical field [0001] The invention relates to the technical field of rail passenger car body measurement, in particular to a visual tracking-based automatic car body measurement device and a measurement method thereof. Background technique [0002] At present, the measurement of the geometric dimensions of the rail passenger car body is carried out manually using a tape measure. The measurement accuracy is poor, the efficiency is low, and the measurement data cannot be automatically generated into an electronic file. It needs to be manually entered into a computer to generate an electronic file, which restricts the development of rail vehicle technology. The industrial photogrammetry method adopts close-range photogrammetry technology, which requires marking points on the workpiece to be measured, which is not suitable for automatic measurement, and the photogrammetry data is sparse point cloud data, which is not suitable for rail passenger cars. [0003] Based on the meth...
