Online detection method and system, terminal equipment, storage medium and detection head

Abstract

The invention discloses an online detection method and system, terminal equipment, a storage medium and a detection head. The method comprises the following steps that 1, an image frame of a cleaning detection area formed after each to-be-cleaned detection area in the axial direction of a wheel shaft is subjected to laser cleaning is acquired along a laser cleaning route; 2, an R value, a G value and a B value of each pixel point of the image frame are obtained; 3, when the R value is not within the R preset range value, the G value is not within the G preset range value, and when the B value is not within the B preset range value, the following steps are executed: marking a cleaning detection area corresponding to the image frame as a to-be-cleaned detection area, and forming a new laser cleaning route; and 4, the steps are repeatedly executed till the R measured value of each pixel point of each image frame is within the R preset range value, the G measured value of each pixel point of each image frame is within the G preset range value, and the B measured value of each pixel point of each image frame is within the B preset range value, and laser cleaning on the wheel shaft is stopped. The method is combined with automatic equipment, is less affected by the environment and is high in precision.

Description

technical field [0001] The technical field of laser cleaning and detection of wheel shafts of the present invention, more specifically, relates to an online detection method and system, a terminal device, a storage medium, and a detection head. Background technique [0002] Subway trains need to carry out flaw detection and repair on their wheel shafts regularly. Before the maintenance, the paint on the surface of the subway wheel shafts needs to be cleaned. Laser cleaning is a new cleaning method developed based on the interaction between laser and matter. Compared with traditional cleaning methods such as mechanical friction cleaning, chemical corrosion cleaning, liquid solid strong impact cleaning and high-frequency ultrasonic cleaning, this cleaning method is environmentally friendly. , non-contact, precise control and other advantages. However, due to the various mechanisms of laser cleaning for the removal of the same pollutants and the complex cleaning environment, t...
