A solar panel substrate planeness non contact system,which employ declinate optical triangulation method,and bases on virtual precise benchmark,is presented.On the basis of a new modeling method of virtual precise measuring benchmark and measurement error compensation technique,the measuring system can accurately measure the solar panel substrate planeness on a non precision plate.The actual measurement results show that the measurement accuracy 0 02mm(RMS) can be obtained when a solar panel substrate (2581mm×1755mm) planeness is measured by using of this measuring system.
