Embodiment Construction

[0013] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with the embodiments and accompanying drawings. The embodiments are only used to explain the present invention and do not constitute a limitation to the protection scope of the present invention.

[0014] Such as figure 1 It shows an embodiment of a three-dimensional laser scanning online detection profiler of the present invention, which includes a housing, and an image acquisition subsystem is arranged in the housing, and the image acquisition subsystem is used to project laser light onto the object to be measured. After the acquisition, the image is transmitted to the image sub-processing system through Ethernet, and the image sub-processing system preprocesses the data sent by the image acquisition subsystem through image processing algorithms to highlight the center feature of the light bar and obtain the two-dimensional image of the me...

Abstract

The invention discloses a three-dimensional laser scanning on-line detection profiler, which comprises a shell, wherein an image acquisition sub-system is arranged in the shell. The image acquisition sub-system is used for projecting laser onto a detected object; after being acquired by a camera, an image is transmitted to an image sub-processing system through an Ethernet; the image sub-processing system pre-processes the image transmitted by the image acquisition sub-system through image processing algorithm to highlight the characteristics of a light strip center and then obtain the two-dimensional size of the detected object; the three-dimensional profile size of the detected object is determined by combining the two-dimensional size with a displacement size of the detected object which is provided by an external control sub-system; and the image acquisition sub-system, the image sub-processing system and the control sub-system are commonly connected with a power system. The three-dimensional laser scanning on-line detection profiler of the invention has the advantages of realizing three-dimensional model detection of a product, guaranteeing the quality of the product and improving the production efficiency, along with short detection time.

Description

Technical field: [0001] The invention relates to a three-dimensional laser scanning online detection profiler, which is used for detection in the field of papermaking, automobile manufacturing, road surface detection, semiconductor and chip production, food industry and mechanical finishing. Background technique: [0002] In the field of automation, detection is an important part, and its measurement method is instrumentation. However, offline detection is used in the existing field of automation. Off-line detection methods can only distinguish products into qualified products and waste products, and play a role in product acceptance and The function of waste rejection has no ability to prevent the occurrence of waste in advance, that is, it cannot remove unqualified products, and the test time is long, the efficiency is low, and the quality control cannot be carried out in a timely and effective manner. Invention content: [0003] The purpose of the present invention is t...
