<P>PROBLEM TO BE SOLVED: To provide an automatic surveying method of surveying the position and direction of an excavator with respect to automatic surveying of the position and direction of the excavator. <P>SOLUTION: The position and direction of the excavator are automatically surveyed through the following processes: (1) predicting a position and a direction of an automatic tracking type distance measuring and angle measuring instrument to be surveyed this time from last surveyed position data of the automatic tracking type distance measuring and angle measuring instrument and movement data thereafter, and then predicting collimation angles at a plurality of reference points set on a portal side; (2) detecting the position of the automatic tracking type distance measuring and angle measuring instrument by collimation from the automatic tracking type distance measuring and angle measuring instrument to the plurality of reference points on the portal side based upon the prediction result of (1); (3) predicting positions and collimation angles of a plurality of targets installed in the excavator from surveyed position data of the excavator; (4)detecting the positions of the plurality of targets installed in the excavator from the automatic tracking type distance measuring and angle measuring instrument based upon the prediction result of (3); and (5) finding the position and direction of the excavator based upon detection results of the positions of the plurality of targets of the excavator. <P>COPYRIGHT: (C)2012,JPO&INPIT |
