Position Detection

1. Pattern Recognition by Gray Processing

In the case of gray processing, an image is treated as a gray scale picture of 256 tones. Unlike binarization which only recognizes black and white, gray processing uses all the information of each pixel which is divided into 256 tones and thus, the target object's pattern shape is accurately recognized.

2. Recognition of Coordinate of an Image on the CCD

Because an image projected on the CCD image pickup element is divided into the pixels of 480(height) × 512(length) as shown in the figure, the X-Y coordinate of any shape within the image is obtained within the range of 0.0 to 511,479.

3. Inspection examples

Robot Handling (Detection of Absolute Position)

Move the robot so that the hole of the target object matches the home position of the screen and then pin the hole.
