Title:
RESIDUAL STRESS MEASUREMENT DEVICE AND RESIDUAL STRESS MEASUREMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2011/152123
Kind Code:
A1
Abstract:
Provided is a device for measuring residual stress of a resin molded article. The device includes color component data acquisition means for acquiring color component data of three primary colors representing a photoelastic image of a resin molded article, amplitude vector computation means for obtaining an amplitude vector representing the energy of brightness of each pixel from the color component data of each pixel constituting the photoelastic image, frequency vector computation means for obtaining a frequency vector representing the energy of color of each pixel from the color component data of each pixel constituting the photoelastic image, and combination means for combining the amplitude vector and the frequency vector to obtain an optical energy vector of each pixel constituting the photoelastic image.
