Our team aims at the improvement of soccer agent’s ability of situaltion recognition and action dicition by saving environmental information as a spatial image. In real time simulation, such as soccer game, the agent needs to have all environmental informaion in order to make a right judgement of situation and make decition own action[Ito99, Nitta88]. However, soccer agents are limited the sight information are acquired form soccer server[SS98]. Then, our team aims at the improvement of agent’s ability of situation judgement with saving of the spatial image in the spatio-temporal databese[Erwing98]. As a result, soccer agent can make judement own environment with not only sight information from soccer server but enviromnet outside the sight range used by this spatiotemporal databese. However, the inforamtion, which is given from socer server, is uncertainty and incompletement. Therfore, it is difficult for agent to make the spatio-temporal database. Then, when a spatial information was saved in the database, the agent made to complete the lack information used by the difference of these items of information in our team. As a result, our agent can make a judgement own environment with virtual spatial information of the spatio-temporal databese, whose information is wider than the range of normal range of the agent. The following, this paper explains our spatio-temporal database and the methods complement of lack information in this database.
