Abstract

The invention discloses a method and device for acquiring a target contour. The method comprises: a radar wave is transmitted to a target; a radar echo of the radar wave on a target is acquired, the radar echo comprises a plurality of reflection points of different detection frames; the plurality of reflection points are overlapped, and a point cloud picture corresponding to the target is obtained; the contour information of the target is obtained according to the point cloud picture, wherein the contour information comprises the height of the target. The method solves the technical problem inthe related art that the height of the target cannot be detected when the radar performs contour recognition on the target.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a method and device for acquiring a target outline. Background technique [0002] Existing millimeter-wave radars do not have the ability to give the outline of the target object, for example, cannot measure the height of the target object. In addition, although the existing millimeter-wave radar can measure the width of the target object, the measurement accuracy of the width of the target object is relatively low. [0003] For the problem in the above-mentioned related technologies that the height of the target cannot be detected when the radar is used to recognize the contour of the target, no effective solution has been proposed so far. Contents of the invention [0004] Embodiments of the present invention provide a method and device for acquiring an outline of a target, so as to at least solve the technical problem in the related art that the height of th...
