In manufacturing, the complex shape of arched metal parts containing curved surfaces and curved elements makes their inspection a challenging task. Traditional inspection methods often struggle to meet the requirements of high accuracy and comprehensiveness, especially when faced with large spans, lack of characteristic edges and complex site conditions. In order to solve these problems, POMEAS has launched a high-precision 3D shape inspection system - POMEAS 3D Profile Measuring Instrument, which provides a brand new solution for the inspection of arched metal parts.

Difficulty in scanning arched metal parts:

1、Decrease in accuracy due to large spanning diameter: Arch-shaped metal parts often have a large spanning diameter, which not only increases the observation distance, but also makes the point cloud accuracy and density decrease, affecting the accuracy of point cloud splicing and feature extraction.

2、Lack of characteristic edges: Arch-shaped metal parts are composed of multiple surfaces and curves, and lack of characteristic lines such as edges and intersections, which makes it difficult to find corresponding references when splicing the 3D model, and increases the difficulty of point cloud splicing.

3、High precision requirements: the manufacturing precision of the arch-shaped metal parts requires high precision, so its detection also puts forward a higher standard. Need to ensure that the measurement results are accurate and comprehensive to meet the needs of quality control and subsequent processing.

4、The site conditions are complex: in the manufacturing site, there are often space constraints, construction interference and other issues, which further increases the difficulty of arch metal parts detection.
