Active Alignment, EOL Testing, and SPC for Fleet Camera Manufacturing
Mass Production is the Ultimate Touchstone of Design
In the practice of imaging engineering, a question that frequently troubles R&D teams is: Why do camera modules that perform perfectly in laboratory testing frequently exhibit edge blur, focus shift, or excessive distortion on the factory production line? Why is there a significant difference in image quality consistency between different manufacturing batches, even when identical sensor and lens specifications are used?
The root of these problems lies in the fact that the image quality of a camera system is not solely determined by component specifications, but is shaped by both design tolerance and manufacturing consistency. In Article 1: Component Selection, the discussion focused on selecting suitable hardware components under extreme environmental requirements; in Article 2: Lab Build-up & Management, a high-precision measurement system was established; in Article 3: Intrinsic & Extrinsic Calibration, the geometric infrastructure of the camera...
