Abstract In order to realize the on-site rapid detection of the thickness and size of the nuclear power heat exchange plate, a line laser three-dimensional measurement system is builded for the thickness detection of complex thin-walled parts. According to the digital model and the constantly changeable surface curvature of the heat exchange plate, the thickness calculation method based on the distance between points and the spatial clustering is proposed to realize the efficient calculation of its thickness. The experimental result shows that the measurement accuracy of the system is better than 0.15mm, the inspection time is less than 2min, and the calculated average thickness of the heat exchange plate is 0.9921mm, which can meet the enterprises on-site (measurement accuracy is better than 0.2mm, inspection time ≤5min) inspection requirements.

Key words： metrology thickness measurement nuclear heat exchange plate line laser scanning pose calibration
