STRESS MEASUREMENT SYSTEM, STRESS MEASUREMENT METHOD AND STRESS MEASUREMENT PROCESSOR

摘要

PROBLEM TO BE SOLVED: To simplify a configuration, and to improve measuring accuracy.SOLUTION: A stress measurement system includes: an infrared camera 63; and a processor 65 for performing image processing to a time series image GA1 imaged by the infrared camera 63. The processor 65 includes: a storage part 651; an image acquisition part 652; an FFT part 653; a filter processing part 654; and an inverse FFT part 655. The FFT part 653 generates first frequency data by performing Fourier transformation processing to the first time series data of each of pixels configuring the first time series image GA1. The filter processing part 654 generates second frequency data by performing filter processing to the first frequency data. The inverse FFT part 655 generates the second time series data of each pixel by performing inverse Fourier transformation processing to the second frequency data, and stores this in the storage part 651.
