description The invention discloses a high-temperature three-dimensional digital image related measurement system and method based on a single camera, and belongs to the field of digital image application. The system comprises a He-Ne laser, an industrial camera, a plane mirror II, a plane mirror I, a plane mirror III, a beam expander, a collimating mirror, frosted glass and the like. Green random speckles are sprayed on a measured object to serve as identification points I, random red speckles are generated by a He-Ne laser through frosted glass to serve as identification points II, the identification points I move along with movement of the measured object, and the identification points II do not move. Displacement fields are respectively calculated for speckle images of the identification points Iand II, and the difference value of the two displacement fields is used as an actual deformation field of the measured object, so the influence caused by thermal disturbance is greatly eliminated. Thesystem is used for measur
