A reverse measurement system about the data collecting of 2-D object edge based on machine vision is discussed,in order to realize digital data input of the dimensions of 2-D object complex edge. This system realized calibration in large scene by virtual grid calibration method, and advanced the precision of system by using double CCD cameras. It realized data mergence by setting up referencer of regular shape. Some methods were put forward to realize graphics vectorization such as using eight-chain code difference to search for the turning points, and using change-length subjunctive beeline to distinguish linetype. The output data use the general DXF document format to connect the software of CAD. Research indicated that this system can be applied in reverse measurement to the dimensions of 2-D object complex edge.

As for the mid-June 2006 Mei-yu case, the assimilation of both kinds of data can help the simulation of radar reflectivity. Further investigations show that the assimilation of dropsonde and QuikSCAT data produces stronger southerly environmental winds in the Bilis case, resulting in a better simulated track than the runs without these data. In these runs, the simulated tracks are too far to the south compared with the observed. In the Kaemi case, the tracks of simulations without dropsonde/QuikSCAT data assimilation were shifted to the north/south of the observed track, respectively.
