    摘要： In a target detecting technique using a laser sensor, misdetection can be reduced while maintaining a wide detecting range. A target detecting method for detecting a target by emitting a laser beam diagonally downward from an installing position of a laser emitting and receiving portion. The method includes the steps of: obtaining distance information from the laser emitting and receiving portion to an object to be detected; determining, when the object to be detected approaches the laser emitting and receiving portion, whether the tracking of the object to be detected is stopped or not; and determining, when the tracking of the object to be detected is stopped, whether the object to be detected is the target or a non-target based on distance information immediately before the tracking of the object to be detected is stopped.
