- Abstract:
- Social video surveillance widely distributed in urban and rural areas,is an important data source for post-earthquake disaster acquisition. Based on seismic video disaster interpretation system,we improved the main technical principle and analysis processing process of video motion estimation method,and applied it to the rapid evaluation of seismic influence field of Lin'an M4.2 earthquake in Zhejiang. The results show that the intensity distribution based on social monitoring is obtained within 4 hours after the earthquake by using the improved method. The maximum calculated intensity is the same as that in the field investigation. The dominant direction of isoseismal line is consistent with that of field work,and the area of V degree is close to that of field work.
