An AVI machine relies on a precise camera and sensor setup to achieve accurate image acquisition. Engineers select cameras based on the specific needs of the inspection process. The most common types include area scan cameras, line scan cameras, 3D vision cameras, and infrared or thermal cameras. Each type serves a unique purpose in manufacturing environments.
| Camera Type | Description | Applications |
|---|---|---|
| Area Scan Cameras | Capture two-dimensional images, ideal for detailed analysis of stationary or slow-moving objects. | Robotic guidance, production monitoring, quality inspection. |
| Line Scan Cameras | Capture images one line at a time, suitable for inspecting continuous or moving objects. | Used in printing, textiles, and food processing. |
| 3D Vision Cameras | Provide depth perception, capturing three-dimensional data for precise measurements. | Robotic picking, stacking, and sorting. |
| Infrared/Thermal Cameras | Detect heat emitted by objects, converting it into visual data for monitoring temperature variations. | Identifying potential issues in various applications. |
The choice of camera and sensor setup directly affects the accuracy of image acquisition. Several factors influence this process:
- The size of the image sensor impacts image blurring; small movements can cause significant blur.
- Stabilization techniques, such as vibration isolators and stroboscopic lighting, help reduce errors from vibrations.
- Optical errors, including spherical aberration and astigmatism, can be minimized with specific lens combinations.
- Higher sensor resolution lowers quantization error but increases processing time, requiring a balance.
- Proper lighting design is essential for high image quality, with different illumination types affecting results.
Capturing Product Images
Capturing high-quality product images is a multi-step process in an AVI machine. The procedure begins when a positioning detector identifies the object within the camera’s field of view and sends a trigger signal. The imaging system then activates the camera and lighting according to preset instructions and timing. The camera starts a new frame scan, either restarting from a previous scan or beginning fresh.
Before scanning, the camera’s exposure mechanism activates, with exposure time set in advance. The lighting system turns on in sync with the exposure time to ensure optimal illumination. Once exposure is complete, the camera scans and outputs a frame of the image. The image acquisition system receives the video signal, converts it into digital data, and stores it in the processor’s memory. The processor analyzes the image to extract measurements or control values, guiding actions such as positioning, error correction, or assembly line control.
Adequate lighting remains crucial for capturing high-resolution images. Inspection systems often include specialized illumination features to ensure proper lighting. However, challenges such as complex surface textures and variations in part appearance can complicate the process. Engineers must configure cameras and lighting carefully to accurately capture defects and maintain quality control.
