In order to establish the 3D Temperature Field based on structure light 3D measurement and cross-correlation registration. Infrared/Visible camera calibration method and heterologous images registration method were studied. First, according to infrared camera’s characteristics, the selection of calibration templates have been studied and the calibration of the infrared camera has been accomplished on the basis of planar calibration method; then, we simplified the two-step method based on the mature principle of structure light measurement; and the visible camera was calibrated; finally, use calibrated visible cameras to form structured light measurement system, and register the infrared image and visible image in the geometrical position. Experimental results show that: the relative error of measurement system is less than 0.3%;infrared and visible image’s alignment error in geometrical position is 0.0015 mm. and measurement systems have good reconstruction results for plane and curved ,and cross-correlation method has a good effect for heterrologous images registration.
