3D scan cameras are capable of inspecting objects across X, Y, and Z planes, determining their position and orientation within space. These cameras use either single or multiple units along with laser displacement sensors. In a single-camera configuration, the camera moves to create a heightmap from the laser’s displacement on the object, allowing for the calculation of the object’s height and surface flatness with a calibrated laser. In a multi-camera arrangement, laser triangulation is used to build a detailed 3D model of the object’s shape and spatial location.

Key specifications of image sensors include resolution and sensitivity. Resolution indicates the number of pixels in the digital image, with higher resolution sensors delivering more detailed images, which enhances the inspection of fine details and the accuracy of measurements. It also affects the sensor’s ability to detect minor variations. Sensitivity measures the smallest amount of light needed for the sensor to produce a discernible change in the image. There is an inverse relationship between resolution and sensitivity: as resolution increases, sensitivity tends to decrease.

Magnification is calculated by dividing the smallest measurement of the field of view by the smallest sensor dimensions. This factor is influenced by the lens’s focal length and the working distance.

Hyperspectral imaging systems offer inspection capabilities beyond the reach of conventional cameras that focus solely on surface analysis. This sophisticated technology is expected to increasingly become the benchmark for quality control in various industries.

Hyperspectral cameras decompose a signal into its spectral components, projecting each component onto a single pixel with minimal energy exposure. The technology behind hyperspectral imaging is evolving rapidly, extending its spectral range from the usual 930 to 1700 nm to a broader range of 1700 to 2500 nm, accommodating a variety of materials.

While pills in a batch may appear uniform to both cameras and human observers, hidden impurities and defects beneath their surfaces can go unnoticed. Hyperspectral imaging is capable of identifying and marking these issues for removal.

Lighting plays a crucial role in machine vision systems by illuminating the object and highlighting its distinct features for the camera to view. Effective lighting is essential because the camera cannot inspect objects it cannot see. Therefore, lighting parameters such as the distance between the light source, camera, and object; angle; intensity; brightness; and the shape, size, and color of the lighting must be carefully optimized to enhance the features being inspected. Additionally, the object’s surface properties must be considered to ensure it is clearly visible to the camera when illuminated.

Machine vision systems are capable of measuring features as small as 25.4 microns. This functionality is often combined with flaw detection to evaluate the irregularities found in parts. Additionally, these systems can be used to determine the volume of components.

In semiconductor quality control, detecting flaws and accurately positioning components are essential tasks. Machine vision systems play a crucial role in addressing these needs effectively within the industry.

Testing the machine vision system might reveal the need to modify or replace components to more effectively achieve the application's objectives.

The vision processing unit in a machine vision system employs algorithms to interpret the digital image captured by the sensor. This processing can take place either externally via a computer or internally within standalone vision systems. Initially, the digital image is retrieved from the sensor and sent to the processing unit. The image is then enhanced to highlight key features before analysis begins. During analysis, the system identifies and measures the specific features of interest. These measurements are compared against predefined standards and criteria. The final step involves making decisions based on this comparison and relaying the outcomes.

Machine vision systems are typically composed of five elements (or components), as discussed below. These components are common and may be seen in other systems. However, when these components work together by playing their distinct roles, they create a vision system capable of sophisticated functions.

Positioning is the process of comparing the location and orientation of the part to a specified spatial tolerance. The location and orientation of the part in 2D or 3D space are communicated to a robot or a machine element for it to align or place the target in its proper position or orientation. Machine vision positioning systems offer more accuracy and speed than manual inspection, alignment, and positioning. Practical positioning applications include robotic pick-up and placement of parts on and off the conveyor belt, positioning of glass substrates, checking of barcode and label alignment, checking of IC placement in PCB, and arrangement of parts packed in a pallet.

Area scan cameras employ rectangular image sensors to capture images in one complete frame. The digital image produced has dimensions that correspond to the sensor's pixel count. The vision processing unit processes each scene individually. Area scan cameras are versatile and can handle most standard industrial tasks, offering simpler setup and alignment compared to line scan cameras. They are especially useful for inspecting stationary objects, allowing for brief pauses to facilitate thorough examination.

Flaw detection is widely used to inspect semiconductor and electronic components, appliances, tooling conditions, food products and their packaging, materials produced in continuous webs (e.g., paper, plastics, metals), and others. Flaw detection is useful in online inspections; once a failing part is detected coming from a process, the process is halted immediately and corrected, and the failing part is separated from its lot. Flaw detection is typically incorporated in machine vision systems together with presence inspection, measurement, and positioning functions.
