Three-dimensional real-time gluing detection method and device

Abstract

The invention discloses a three-dimensional real-time gluing detection method and device for detecting the width, height and continuity of adhesives in a robot gluing process in real time. The three-dimensional real-time gluing detection method is characterized by comprising the steps of first of all, carrying out a teaching process, subdividing and quantizing glued adhesive tape into different adhesive tape segments, ranking the adhesive tape segments, selecting started cameras and started lasers which correspond to the adhesive tape segments with different sequence numbers, and when detection is carried out, calculating the width and height of the adhesive tape segments to be measured based on a structured light image three-dimensional measurement principle to judge whether or not the glued adhesive tape is qualified. According to the gluing detection method and device, three-dimensional data of the adhesive tape is analyzed, and therefore the width and height of the adhesive tape can be calculated. Compared with an existing detection method, detection on height information of the adhesive tape is added. Besides, when the color of the adhesive tape is similar to or the same as that of a glued workpiece, the detection method of the device still can effectively analyze the quality of the adhesive tape.

[0003] In the prior art, it has been verified that analyzing the coating quality through image processing technology is an effective detection method. The existing method can be described as using the two-dimensional image of the adhesive strip to be tested, and analyzing the adhesive strip and the coated workpiece in the image. The color difference between them can realize the extraction of the edge of the glue strip, and then obtain the width information of the glue strip. The height information is not involved, and when the color of the glued strip is similar or consistent with the color of the coated workpiece, the existing method cannot detection
