Three-dimensional Dimension Measurement Method of Multi-type Glue Based on Line Structured Light Sensor
In order to solve the current problems of low accuracy of industrial dispensing quality detection and poor algorithm versatility,a multi-type glue three-dimensional size measurement method based on line structure light sensors was proposed.This method used a line structured light sensor to collect glue images,designed a tilt correction method to solve the problem of inaccu-rate height map data caused by external influences,and then a three-dimensional measurement method for glue was proposed.A linear scanning width measurement method and a skeleton extraction width measurement method were designed and optimized for various shapes of glue,and an adaptive width measurement method was proposed by combining the two.Through comparative analysis,the experimental results show that the proposed measurement method can effectively adapt to various shapes of glue to achieve high-precision three-dimensional measurement,and the average relative error of measurement is as low as 0.55％,which has strong versatility and accuracy.
