PROBLEM TO BE SOLVED: To allow high accuracy in distance estimation value and distance change rate estimation value, after batch processing by using a two-dimensional angle observation value by turning into high accuracy the distance estimation value initial value and distance change rate estimation value initial value, using the two-dimensional angle observation value. SOLUTION: A sensor information confluent system includes: a two-dimensional angle following means for calculating a two-dimensional angle track, based on two-dimensional angle observation information due to a sensor; a two-dimensional angle observation information compression means for calculating integral two-dimensional angle observation information, by performing compression processing due to minimum square integration based on a compression interval preset in the two-dimensional angle observation information and the two-dimensional angle track; a distance estimation value initial value calculating means for calculating the distance estimation value initial value and the distance change rate estimation value initial value, based on three-point integral two-dimensional angle observation information; and a distance calculation batch processing means for calculating the distance estimation value and the distance change rate estimation value, by regarding the calculated initial values as the initial values and accumulating and batch-processing the number part of batch data presetting the two-dimensional angle information.
