• Optical System: Includes a laser/structured light projector, optical lenses, and imaging sensors (CCD/CMOS, PMT, APD, etc.). Laser systems form the measurement beam through defocusing/focusing; structured light systems project stripe/grid patterns to acquire surface shape information; the high-sensitivity detector at the receiver directly affects ranging accuracy and signal-to-noise ratio.
• Scanning Device: Consists of a mechanical rotating platform (horizontal/vertical rotation for spatial coverage) and a fixed scanning head (internal line/frame scanning via mirrors/galvanometers). Its field of view and scanning density determine the point cloud resolution and coverage efficiency.
• Motion and Support Structure: Composed of linear guides, a rotary table, a multi-axis robotic arm, and a support/base. Emphasis is placed on rigidity, thermal stability, and vibration reduction to ensure geometric accuracy during repetitive positioning and long-term data acquisition.
• Control System and Communication Interface: Centered on an embedded control unit, it coordinates the light source, scanning, and acquisition. It provides interfaces such as USB, Ethernet, and Wi-Fi to support local/remote parameter setting and data transmission.
• Data Processing Unit: Composed of a data acquisition card/industrial computer/GPU, it performs computationally intensive tasks such as filtering, calibration, registration, reconstruction, and detection. High-end equipment supports real-time preprocessing.
• Power Supply and Auxiliary Modules: Includes regulated power supply, overvoltage/overtemperature protection, fan/temperature control, and ambient light suppression/shielding accessories to ensure system reliability and consistency under complex operating conditions.
