Main teaching situations: close-range photogrammetry, application of mathematical planning in undergraduate survey, and industrial survey of undergraduates. The main research direction of graduate students has been from 1990 to now, and the related theories and methods of close-range photogrammetry and industrial measurement have been studied. Based on the condition that the laser beam direction of laser theodolite is known, the scanning mathematical model is studied, and two sets of measurement schemes, photogrammetry and engineering measurement, are established and applied to many practical projects. At the same time, the extraction method of structured light fringes in images is studied. The related algorithms of multi-intersection close-range photogrammetry, such as the automatic measurement method of artificial marker points in images, are studied, and a set of digital testing software is completed, including image point measurement, camera calibration, target point three-dimensional coordinate calculation and other modules. The on-line industrial measurement based on goniometer is systematically studied and applied to practical engineering.
