| Abstract: | The laser & imaging measurement system is considered as a new one for deflection measurement of large bridges.On basis of its measurement principle,to prove its stability,both outdoor and indoor experiments are carried out.It is demonstrated that this system has good stability and feasibility in indoor condition,and it can be used to measure the deflection of large rigid bridges with sealed beam. |
