This paper reviews the development process of the locomotive simulator vision system and analyzes the shortcomings of the traditional methods. Based on the characteristics of the system, through the deep research on the coding theory and image sequence, the application of video compression technology to the locomotive simulator vision system New ideas and new concepts. Introduced in detail based on the MPEG 1 standard system solutions, including compression / decoding system. A smooth speed regulation algorithm based on image sequence analysis and an inter-frame interpolation algorithm at low speed are proposed. In order to simulate the change of the scene, the method of implementing the special effects processing is proposed.
