摘要（英）：

The invention discloses a three-dimensional calibrating target for a laser scanning plane of active vision measurement of automobile morphology, and aims to solve the problem that laser planar calibration of an active vision measurement system of automobile morphology cannot be realized by adopting the three-dimensional calibrating target to collect an image by a camera. The three-dimensional calibrating target for the laser scanning plane of active vision measurement of automobile morphology consists of a target frame (1), a steel wire rope (2), a double-screw bolt (3) and a bolt (4). The invention provides the three-dimensional calibrating target for the laser scanning plane of active vision measurement of automobile morphology, wherein the base level of a target coordinate system can be superposed with that of a world coordinate system of a detection line and calibration can be realized by collecting one image. The three-dimensional calibrating target for the laser scanning plane of active vision measurement of automobile morphology is simple in structure, high in detection precision, small in accumulated error, integral in function, simple and convenient to operate, easy to install, strong in universality and reliable in performance and can satisfy the quick calibration demand on the laser scanning plane of active vision measurement of automobile morphology in the automobile detection industry.
