Flight safety is very important issue for aviation industries. Analyzing the flight accidents on the basis of 2-dimensional
image is hardly to illustrate the complex injuries of passengers in the flight cabin. However, how to illustrate the flight
accident is a challenge from 2-dimensional space to 3-dimensional space. This study proposes a particle swarm
optimization approach for improving the identification of objects from 2-dimensional image. The recognition results
provide the information for building 3-dimensional systems for flight accident investigators. The experiments also show
that it is a feasible approach for improving the identification of image objects.
