Description

Rail profile detection method, system and storage medium Technical Field The application relates to the field of railway track detection, in particular to a method, a system and a storage medium for detecting a steel rail profile. Background At present, the detection of the profile of the steel rail mainly comprises two types, namely a contact type detection and a non-contact type detection, wherein the contact type detection is divided into two types, namely a mechanical abrasion ruler and an electronic measuring instrument. The non-contact detection method is mainly based on an optical detection technology to realize steel rail profile data acquisition and mainly comprises two directions of vehicle-mounted detection and portable detection. The accuracy of the contact type detection method can reach a higher degree, because the detection equipment and the surface of the steel rail need to be in close contact, the detection efficiency is low, the equipment is easy to wear, and the defect is unavoidable in the contact type detection, and is particularly prominent in the traditional abrasion ruler detection method. The contact type inspection mode has the characteristics of high inspection precision and portability, and is more suitable for a scene of small sampling detection. The non-contact detection mode mainly depends on an optical detection technology, so that dynamic non-contact detection is realized, and the detection efficiency is improved to a higher level. In the vehicle-mounted detection direction, the actual detection precision is reduced to a certain extent compared with the theoretical detection precision due to the interference of the severe detection environment, and in the off-vehicle detection direction, the interference of most of the severe environments is effectively avoided, and the detection precision is improved. The cost of the optical detection device is relatively expensive.
