Experimental Detection of Composite Delamination Damage based on Ultrasonic Infrared Thermography
An experimental setup is designed to detect composite delamination damage based on ultrasonic infrared thermography. The ultrasonic infrared thermography system is composed by ultrasonic excitation system, infrared thermal imager and data acquisition system and two damaged composite plate specimens are produced in the experiment. The image processing methods including thresholding, filters, edg...
متن کاملextremal region detection guided by maxima of gradient magnitude
a problem of computer vision applications is to detect regions of interest under dif- ferent imaging conditions. the state-of-the-art maximally stable extremal regions (mser) detects affine covariant regions by applying all possible thresholds on the input image, and through three main steps including: 1) making a component tree of extremal regions’ evolution (enumeration), 2) obtaining region ...
Double Pulse Infrared Thermography
0. Abstract In this paper we propose a simple enhancing protocol for pulsed infrared thermography. The method is based on stimulating the specimen with two heating pulses separated by a short time interval delta. This approach was tested on several specimens of low and high thermal diffusivity and showed to provide higher thermal contrasts when an optimum interval delta is chosen. The observed ...
متن کاملApplications of Pulse Phase Thermography
Recently, a novel approach was proposed which combines advantages of both pulse (PT) and modulated (MT) infrared thermography. In a nondestructive evaluation (NDE) perspective, the specimen is pulse-heated as in PT and the rnix offrequencies ofthe thermal waves launched into the specimen are unscrambled by perforrning the Fourier transform of the temperature time evolution over the field of vie...
متن کاملThermography Based Hotspot Detection and Protection System
This paper is about the thermal diagnosis and control of electric machines or transformer using a Thermal image camera, color sensor, a microcontroller and a PLC. A color sensor is developed which respond to the colors of thermographic images and when overheating or Hot spot occurs it automatically give alarm signal or it can be used to switch off the electric machines or transformer.
