Abstract: A container position measuring method using a microwave sensor 31 which emits microwave 35 and receives reflected wave of the microwave 35, wherein a position of a corner portion of a transportation container is measured by reflected wave from the corner portion. The microwave 35 is not influenced by weather and color of a transportation container 18. Therefore it is possible to reliably measure position data of the transportation container. The microwave 35 does not easily receive the influence of weather and color of the transportation container. The present invention provides a position measuring method capable of stably measure position data of the transportation container.
