Abstract

The invention relates to a multi-line laser sensing closed layout structure, a scanning splicing method and a gluing scanning method. The layout structure is composed of a closed polygon which is formed by projecting a plurality of laser rays within a working distance by one laser for integral projection or a plurality of lasers for respective projection; each laser ray is monitored and measured by an independent receiver or camera, and the receiver only calculates distance information of the corresponding laser ray; the middle area of the polygon is a monitoring target area; during operation, the middle area is fixedly wrapped with an object to be detected; within the working distance, the horizontal projection of the laser line still needs to keep a closed polygonal graph; the number and the projection angle of the laser rays are determined by the shape and the edge included angle of a detected object; when the to-be-detected object is located in the closed contour, no matter the multi-line laser group moves from any direction, the posture of the multi-line laser group does not need to be changed, and at least one receiver scans the to-be-detected object.

Description

technical field

[0001] The invention belongs to the technical field of industrial detection, and in particular relates to a closed layout structure of multi-line laser sensing, a scanning splicing method and a gluing scanning method. Background technique

[0002] The current industrial detection technology means, commonly used scanning detection means: install a line laser sensor at the end of the moving mechanism, and move through the mechanism to complete the scanning process of the target workpiece. Mobile mechanisms include industrial robots, multi-axis linear modules and other multi-degree-of-freedom mechanisms.

[0003] However, for processes that require simultaneous processing of the object to be measured during real-time scanning, such as gluing, welding, additive manufacturing, and subtractive manufacturing, the line laser scanning line must continue to cover the processing part. For such applications, the following schemes are often used if the workpiece consiste...
