The invention discloses a temporary obstacle handling method for laser slam navigation, which is applicable to the factory environment. The temporary obstacle handling method is characterized by comprising the steps of: S1, importing a positioned static map into an AGV, and using the static map as a background map of an alarm map; S2, displaying an occupied area and an expanded area of a fixed obstacle on the alarm map; S3, setting two-level alarm areas including a first-level alarm area and a second-level alarm area; S4, detecting an obstacle by means of a laser scanner, judging whether the obstacle is a fixed obstacle or a temporary obstacle based on the detection result, and displaying the temporary obstacle detected by the laser scanner on the alarm map; S5, detecting whether the AGV is positioned in a human-computer interaction area or an AGV exclusive area, carrying out no operation on the temporary obstacle when the AGV is positioned in the human-computer interaction area, and executing a step S6 when AGV is positioned in the AGV exclusive area; S6, and selectively performing speed reduction, stopping or running at an original speed by the AGV based on the judgment result ofthe step S4.
