Four Types of Machine Vision Systems

1D Vision Systems

1D Vision Systems are specialized in analyzing images to extract data from patterns in a single dimension. They are primarily used for scanning barcodes and other linear marks. These systems are adept at identifying, inspecting, and guiding parts in manufacturing processes, ensuring the correct positioning and verifying the presence of linear codes for tracking and traceability purposes.

2D Vision Systems

2D Vision Systems capture and analyze images in two dimensions (width and height). They are versatile and widely used in quality control, inspection, and automation across various industries. These systems can detect defects, measure parts, read printed characters (OCR), and verify assembly completeness. They work with both grayscale and color images, providing detailed analysis for surface inspection, part identification, and robotic guidance.

3D Vision Systems

3D Vision Systems extend the capabilities of 2D systems by adding depth perception. They are used to measure volumes, shapes, and positions in three dimensions, enabling precise quality control and material handling. 3D vision is critical in applications requiring accurate dimensional data for object recognition, alignment in assembly operations, and navigation for autonomous robots. These systems use various technologies, including laser triangulation and structured light, to capture the 3D geometry of objects.

4. Spectral Imaging Systems

Spectral Imaging Systems go beyond the visible spectrum, capturing image data at specific wavelengths. These systems are used in applications where material composition or characteristics need to be identified or verified. Spectral imaging is valuable in agriculture for crop health monitoring, in pharmaceuticals for chemical composition analysis, and in recycling for sorting materials based on their spectral signature. By analyzing the spectral data, these systems can detect features invisible to the naked eye or conventional imaging systems.
