Abstract

The invention discloses a vacuum cup size measurement method based on vision, and relates to the technical field of machine vision measurement. The method comprises the following steps: S1, obtaininga conversion coefficient from a pixel to a physical size through calibration of an image coordinate system and world coordinates in a four-eye camera; S2, under an image coordinate system, grabbing ato-be-measured vacuum cup side boundary contour point, and fitting the edge of the vacuum cup through a fitting straight line and a circle; and S3, converting the size detection of the vacuum cup intogeometric measurement. According to the measuring method, the data size of the vacuum cup can be rapidly calculated and analyzed, and the measuring method has the advantages of being high in detection speed, high in detection data precision, high in remodeling speed and the like.

Description

technical field [0001] The invention relates to the technical field of machine vision measurement, in particular to a vision-based method for measuring the size of a thermos cup. Background technique [0002] Thermos cups have advantages in thermal insulation and portability, so it is difficult to replace them in cold areas, outdoors, schools, driving and other fields. Facing the opportunity of population growth and industrial transformation and upgrading, the automatic production line of the thermos cup industry has been gradually upgraded. At present, the appearance and size inspection of thermos cup products mainly relies on manual sampling inspection with vernier calipers. The inspection time is relatively long, and it is easily affected by human subjective consciousness. Contents of the invention [0003] In view of the deficiencies in the prior art, the present invention aims to provide a method for measuring the size of a thermos cup based on vision, which has the ...
