background knowledge

The automotive electronic controller housing serves as a critical protective component for the electronic control unit, and its manufacturing precision directly impacts vehicle safety and reliability. Sheet metal housings have become the preferred solution due to their lightweight and high-strength advantages; however, processes such as stamping and bending are prone to producing three-dimensional defects—including joint gaps and angular deviations—which can compromise assembly accuracy, sealing performance, and even cause electronic system failures.

Traditional 2D vision cannot detect three-dimensional defects, while conventional 3D equipment such as coordinate measuring systems struggle to meet the demands of mass-produced online comprehensive inspection. Next Vision Tech's 3D industrial camera, leveraging its contactless operation, high precision, and rapid online detection capabilities, effectively addresses the limitations of traditional solutions and has become the core technology for precision quality control of automotive electronic housings.
