With the increasing number of the graduate students, many of them have some troubles in job finding. This situation make a huge pressure on the senior students and loss them the interesting in study. This work investigate the reasons by questionnaire survey, panel discussion, interview, etc. to achieve the factors influence their learning interesting. The main reason of students do not have the motivation on study is that they do not understand the development and competition of photoelectric specialty, lack of innovation and entrepreneurship training, hysteresis of the learning knowledge and practical application. Finally, the paper gives some suggestions through teaching reform on how to improve students' learning enthusiasm. This work will contribute to the teaching and training of senior undergraduate students of optoelectronics specialty.
In view of the problem that there are some defects such as poor noise immunity, poor stability, large amount of computation and high redundancy of target feature extraction method in three-dimensional(3D) reconstruction, an accurate and rapid method of extracting laser stripe was put forward according to the continuity of laser stripe pixels in this paper, which references the theoretical characteristics of structure laser and binocular vision, and uses the laser stripe projected onto the surface of the measured object as feature. Through repeated experiments and theoretical analysis comparison, the results show that the method has a great improvement in the accuracy, precision and computational efficiency of extracting laser stripe.
