Beschreibung
Zusammenfassung:	A laser processing apparatus sets a processing section passing through a target position on a processing surface, sets a measurement section centered on the target position in the processing section, sets a plurality of data acquisition positions that are trajectories perpendicular to a processing direction in the measurement section. The laser processing apparatus acquires pieces of measurement data indicating shapes of keyholes at the respective data acquisition positions during processing of the processing section, and projects the pieces of measurement data in the processing direction to be superimposed on each other to create projection data. The laser processing apparatus obtains the second instruction value in a direction perpendicular to the processing direction at the target position on the basis of the projection data. Therefore, it is possible to provide a laser processing apparatus and a laser processing method capable of accurately measuring a depth of a keyhole.
