Solution 4] Shomei problem
This is a continuation from the previous post. Here is an image obtained by using a 2.5mm small ring illumination (high angle). The angle of incidence is close to 90 degrees of the coaxial illumination, so the image is relatively close to the coaxial illumination. The smooth areas that have been rubbed have turned white [...].
Solution (3)] Shomei problem
This is a continuation of my previous post. The following is the image obtained when coaxial lighting was used. The smooth area is almost a mirror, so the direct light from the coaxial illumination hits the frayed area and is captured by the camera as it is [...].
Solution 2] Shomei problem
This is a continuation of my previous post. What would the image look like if coaxial illumination was used in #1? Coaxial illumination, also called coaxial epi-illumination, is illumination that shines parallel (90 degrees) to the camera. The lens cap rubs against the [...].
Solution (1)] Shomei problem
This is the answer to my last post. The answer is 3. Large ring illumination (low angle placement). The reason why the rubbed area turns black is because the normal surface of the camera lens cap is a little rough [...].
problem of proof
There is a scuff on the camera lens cap. In the image below, the abrasion appears as a vertical black streak. Which of the following three types of illumination was used to capture this image? 1. coaxial illumination 2. small ring illumination (placed at a high angle) 3. large [...].
Concept of inspection speed 5
The actual inspection time required by our FIS-100 software varies depending on the resolution of the camera used, the size of the inspection area, and whether it is OK or NG. Basically, the more pixels to process, the longer it takes. &nbs [...].
Concept of inspection speed 4
IN VISUAL INSPECTION, AN IMAGE WITH A CLEAR CONTRAST (DIFFERENCE IN SHADING/BLACK AND WHITE) IS REQUIRED. WHEN INSPECTING A WORKPIECE THAT IS MOVING AT HIGH SPEED, LED LIGHTING THAT IS ALWAYS ON IS INSUFFICIENT TO PRODUCE A CLEAR CONTRAST IMAGE BECAUSE THE OVERALL IMAGE IS DARK.
Concept of inspection speed 3
When inspecting an object moving at high speed, the key is to obtain a clear image (bright image without blurring). To be more specific, the key is to keep the distance traveled during exposure to less than one pixel. In our experience [...].
Concept of inspection speed 2
The capability of the camera naturally has an impact on the inspection speed. When selecting a camera, we look at the "pixel count," "pixel size," and "frame rate" as key factors. The area cameras we often use have a GigE (Gigabit Ethernet) interface (see [...]).
Concept of inspection speed 1
Is it possible to inspect at 1 piece/second? How fast can the speed be increased to inspect the image without blurring? We sometimes receive questions like these. The gear inspection system we exhibited at a recent exhibition was designed to inspect 90 gear teeth [...].
