The HOLON751 handheld 3D scanner was used to perform a comprehensive scan of the speaker housing, capturing high-precision data. Featuring 20 laser lines, the scanner offers rapid scanning speeds; it includes a deep-hole scanning mode for the precise capture of hole locations and a fine mode for detailed scanning of intricate features, ensuring high data accuracy. The captured data was imported into 3D inspection software for analysis, allowing for the precise determination of the spacing between hole locations. The ability of the handheld 3D scanner to accurately acquire high-precision data—and subsequently generate precise reports through analysis—has proven highly beneficial to the client.
