The invention provides a novel method for acquiring a target point by using line laser as a robot tool, and relates to the technical field of line laser point acquisition technologies. The novel method for acquiring the target point by using the line laser as the robot tool comprises the following steps: S1, pre-installation: movably installing the line laser on a machine arm clamp I, and movably installing a welding gun on a machine arm clamp II; and S2, scanning the contour: sending a command through an upper computer, and receiving the command through a lower computer; According to the novel method for acquiring the target point by using the line laser as the robot tool provided by the invention, the line laser is used as an independent tool for calibration, hand-eye calibration with the welding gun is not needed, the actual position of a target welding seam is calculated in combination with a set geometric topology point relation, and the method is suitable for complex components; and during calibration,
