2024/08/02Background knowledge
Headphone manufacturers are under intense pressure as consumers demand sound quality, comfort and durability. Among them, ensuring the flatness of the headset is an important part, because it directly affects the appearance quality of the product and the user's wearing comfort.
Traditional detection methods often rely on manual visual inspection or low-precision measurement tools, which are not only time-consuming and laborious, but also prone to errors. In contrast, the automated detection of a 3D camera can greatly improve the detection efficiency and reliability. It can complete a large number of headphones in a very short time, while ensuring the consistency and accuracy of the test results.
