Based on machine vision technique freight train side rail guard mounting dimension measurement system

The utility model relates to a based on machine vision technique freight train side rail guard mounting dimension measurement system. The problem of there are random error such as reading error, environment error in artifical inspection freight train rail guard among the prior art, influences measuring result, and measurement of efficiency is lower is solved. The system includes the camera unit including ranging module, figure collection module and pattern process module, figure collection module, and ranging module and camera unit connection, pattern process module include image information processing unit, and the camera unit links to each other with image information processing unit. The utility model has the advantages that need not contact freight train side protector, just can effectively measure freight train side protector's mounting dimension fast, detection efficiency is higher.
