Abstract

Embodiments of the invention disclose a ladder data acquisition method and apparatus based on a laser radar, and are applied to a biped robot on which a laser radar is installed. The method includes the steps of acquiring and storing several frames of sampling data collected by a laser radar, wherein each frame of sample data includes N sampling points of the laser radar, where N is a natural number; classifying the sampling points to extract valid sampling points; and calculating ladder data according to the sampling data corresponding to the valid sampling points. The embodiments of the invention reduce the cost of the biped robot, avoid the construction of a multi-radar system, avoid the use of expensive 3D radars, and avoid the construction of a complex radar installation mechanical structure; and the solution hardware configuration is simple and easy to understand, the algorithm used is simple, efficient and controllable, and the control process is simplified.

Description

technical field [0001] The present invention relates to the technical field of laser radar, in particular to a method and device for acquiring ladder data based on laser radar. Background technique [0002] Existing 2D radars are mostly used for path planning and mapping of robots, so as to detect and avoid obstacles. However, in the experiment of going up and down stairs for robots, this method can only identify stairs, but cannot When the robot goes up and down the stairs, it recognizes the height of the steps and the length of the steps. Moreover, since 2D radar can only scan 360-degree distance and angle data on a plane, multiple 2D radars are required to complete the perception and ranging of the 3D actual environment, and the data processing and radar installation locations are relatively cumbersome. 3D radar is too expensive and the radar is too large to be installed on a biped robot. [0003] In the prior art, for the problem of biped robots going up and down stair...
