Detection Principle

The headlight modules of different vehicle models have distinct height thresholds on a 10-meter whiteboard. A stepper motor driven via the 485 bus controls dual linear lasers to project light patterns at corresponding upper/lower limit positions, enabling driver inspection. Digital CCD industrial cameras precisely regulate exposure parameters and capture light pattern images. These images are transmitted to an industrial computer at 20-40Hz frame rate through GigE protocol. IYASAKA proprietary light height measurement software automatically identifies the cutoff line between illuminated and shaded areas projected on the 10-meter board. Based on predefined standards, it determines whether the headlight height falls within specified limits, completing the inspection process.
