Multi-position 3D scanning online detection method

Abstract

The invention relates to a multi-position 3D scanning online detection method. The method comprises the following steps: 1, installing multiple sets of high-precision laser scanners or lenses used forscanning components from different positions and angles on a production line; 2, adjusting the position, angle and number of laser scanners or lenses according to the actual position of a detection part; 3, obtaining a point cloud set of component information through component scanning data acquired by multiple sets of high-precision scanners or lenses; 4, screening the point cloud data by adopting a curvature filtering and element automatic identification algorithm, and quickly calculating the geometrical characteristics of the component; 5, controlling the classification quality through anequipment system, and checking the collected actual detection data of the part to calculate a detection result. According to the invention, contact type detection parts of detection personnel are notneeded, products can be rapidly detected in batches on a production line, and the detection speed and quality are improved by applying intelligent and informationized means.

Description

technical field [0001] The invention relates to the field of detection of conventional components of sleeves, in particular to a multi-position 3D scanning online detection method for non-contact measurement of geometric characteristics of conventional components of sleeves and capable of fast, stable and efficient detection of components. Background technique [0002] Traditionally, the geometric characteristics, organizational structure and appearance inspection of conventional parts of the set are mainly manual sorting. The inspectors use their eyes to check the appearance of the parts, conduct contact measurement on the structural dimensions of the parts, and record the inspection through multiple processes. The data is checked with the theoretical data to check the macroscopic defects of the actual production parts. This inspection method has high requirements for the number of inspection personnel and their own quality, and is highly dependent on the operator. Moreover,...

[0002] Traditionally, the geometric characteristics, organizational structure and appearance inspection of conventional parts of the set are mainly manual sorting. The inspectors use their eyes to check the appearance of the parts, conduct contact measurement on the structural dimensions of the parts, and record the inspection through multiple processes. The data is checked with the theoretical data to check the macroscopic defects of the actual production parts. This inspection method has high requirements for the number of inspection personnel and their own quality, and is highly dependent on the operator. Moreover, the efficiency of manual inspection is low, and it cannot meet the requirements of large-scale production. Batch component inspection, and inspectors are prone to make mistakes during the inspection process, which makes the quality stability of the inspection poor, resulting in the quality of the entire batch of products not being guaranteed
