A barrier data collection device includes a unit estimation unit that estimates, based on sensor data with position information including height at a time when a mobile body including a flying mobile body moving in the air moves, the sensor data being collected in advance about each of geographical ranges, with an estimator, about each of sets of the geographical ranges and heights included in the sensor data in a predetermined time unit, a barrier state obtained by estimating a state of which of barrier types the set is, a shape estimation unit that estimates, about a set satisfying a condition among the sets, a barrier shape based on the sensor data and an estimation result of the barrier state estimated about each of the sets in the time unit, and a barrier estimation unit that estimates, based on the estimation result of the barrier state estimated about the each of the sets, the estimated barrier shape, and a correct answer ratio of the estimator calculated in advance, a probability for each of the barrier types corresponding to each of the sets and estimates the barrier type corresponding to the set from the estimated probability for each of the barrier types.
