The differences between machine vision testing and human visual perception in today's market

The differences between machine vision testing and human visual perception in today's market

Human vision possesses highly advanced intelligence, enabling it to leverage logical analysis and reasoning when identifying objects, as well as to discern underlying patterns. Moreover, the human visual system exhibits exceptional color-discrimination capabilities—but this ability is surprisingly susceptible to psychological influences, making it difficult to quantify accurately. At the same time, our eyes aren’t very adept at distinguishing shades of gray; typically, we can only perceive around 64 distinct grayscale levels. Additionally, our spatial resolution isn’t stellar—making it nearly impossible for us to clearly see extremely small objects.

Our company’s pioneering GOI appearance inspection equipment—what exactly is its biggest advantage?

Our company’s pioneering GOI appearance inspection equipment—what exactly is its biggest advantage?

Our company’s GOI boasts several key advantages: 1. It offers flexible control over external circuits, seamlessly integrating electronic and visual inspection processes. 2. Built on a PC-based application platform, it enables seamless information exchange with customers’ production line MIS systems. 3. Featuring a fully proprietary software platform, we deliver "ready-to-use" product-level solutions—rather than modular visual components that require customers to assemble themselves. In addition to the software platform, our GOI products also provide comprehensive, automated end-to-end solutions.

Introduction to the Measurement Features of GOI, a Machine Vision Product

Introduction to the Measurement Features of GOI, a Machine Vision Product

Our GOI system description mentions that it can measure dimensions, shapes, distances, and sizes—but can it also be used like calipers to precisely determine the dimensions and positional coordinates of parts? On the GOI, measurements of size and distance are calculated in pixel units. Once the resolution is clearly defined, we can accurately calculate the actual dimensions of the part. It’s important to note that when a camera captures a 3D object as a 2D image, measuring objects that aren’t perfectly flat becomes challenging. Similarly, using short-focus lenses may introduce inaccuracies, especially at the edges of the captured image. At its core, the image captured by the camera already represents a coordinate plane, with each point’s position relative to the origin precisely determined. And given the resolution, the exact coordinates of every point on that plane can be accurately mapped. The GOI’s measurement capabilities are similar to AOI’s measurement algorithms, but they cover a broader range of measurement tasks. Detailed descriptions of these measurement features can be found in the system’s comprehensive user manual.

What exactly is the complete workflow of a machine vision system?

What exactly is the complete workflow of a machine vision system?

The general workflow of a complete machine vision system is as follows: 1. The workpiece positioning detector identifies when an object has moved close to the center of the camera system’s field of view and sends a trigger pulse to the image acquisition unit. 2. The image acquisition unit, according to a pre-set program and delay, sequentially issues start pulses to both the camera and the lighting system. 3. The camera either halts its current scan and immediately resumes a new frame, or remains in standby mode until the start pulse arrives—upon receiving the pulse, it initiates a fresh frame scan. 4. Before starting a new frame scan, the camera activates the exposure mechanism, with the exposure duration pre-configured in advance.

General-purpose visual inspection equipment is highly favored by the market.

General-purpose visual inspection equipment is highly favored by the market.

Since its market debut in March 2012, our company’s General Optical Inspection (GOI) product has been successfully deployed across multiple industries, including automotive electronics (such as car dashboards, multimedia systems, and fuse boxes), home appliances, laptops, automated lithium-battery production lines, and flat-panel displays. As labor costs continue to rise domestically, automated inspection equipment is gaining increasing attention from customers. Our GOI solution not only excels in image recognition but also delivers advanced capabilities like measurement, positioning, counting, and solder-joint detection. Additionally, it enables seamless automatic control of external devices and can even integrate with electrical testing systems, allowing for comprehensive electrical and visual inspections of the tested objects. As a result, GOI offers a significantly higher level of automation and efficiency compared to standalone inspection tools, earning widespread acclaim from our valued customers.
