Laser image measurement based coal coke oven carbonization chamber position detection method

Abstract

The invention relates to a coal coke oven charring room position measuring method based on laser image measurement, wherein an oven opposite to the door of coal coke oven charring room is arranged with a reference body, an engine is arranged with a straight laser emitter and a camera to pick the laser image information of reference body, to recognize the reference body via the relationship between the orthogonal coordinate of laser line in the image and the surface concave-convex size of the oven, to calculate the position error between the engine and the target door of the charring room, viathe horizontal pixel of reference body in the image. Or else, the invention uses a solid bar code to replace the reference body, to read inside code information via picked solid bar code laser image,to recognize the serial number of the charring room door via the code, and calculate out the position error between the horizontal pixel and the charring room door via the bar code. The inventive measuring method belongs to non-contact absolute position measuring technique, with strong adaptability on the coke oven producing condition, to realize oven number recognition and accurate measurement of door position error.

Description

technical field [0001] The invention belongs to the technical field of structured light image measurement, and relates to an optical detection method for the position of a carbonization chamber of a coal coke oven, in particular to a target recognition and position deviation detection method based on the principle of laser image triangulation. Background technique [0002] During the coke production process, mobile locomotives such as coal loading vehicles, coke pushing vehicles, coke blocking vehicles, coke quenching vehicles and smoke and dust removal vehicles need to work in different carbonization chamber positions of the coal coke oven. In order to realize the automatic running of the locomotive and the automatic operation of the production machinery, it is necessary to detect the relative position between the locomotive and the coke oven. [0003] The positioning between the locomotive and the coke oven is divided into two problems: "furnace number identification" and ...
