Title:
Debris detection method
Document Type and Number:
Japanese Patent JP6344598
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a debris detection method capable of improving detection accuracy by removing a noise caused by imaging equipment or an imaging environment.SOLUTION: A debris detection method includes: a Step 1 of acquiring a celestial sphere image; a Step 2 of specifying the detection object area of debris from the celestial sphere image; a Step 3 of creating the pixel value distribution of the detection object area; a Step 4 of estimating an approximate Gaussian curve from the pixel value distribution; a Step 5 of calculating an error by comparing the pixel value distribution with the approximate Gaussian curve; and a Step 6 of determining whether or not debris is included in the detection object area 2 by using the error.
