Abstract

The invention discloses a laser triangulation method, belonging to the technical field of parallactic triangulation methods. The laser triangulation method comprises the following steps: deriving a basic formula of laser triangulation; deriving a practically available triangulation formula according to the basic formula of laser triangulation; calibrating triangulation parameters in different intervals; designing mechanical structure parameters; and substituting the calibrated triangulation parameters and the designed mechanical structure parameters into the practically available triangulationformula to calculate a distance. The method improves the accuracy of triangulation by calibrating the triangulation parameters in different intervals and designing the mechanical structure parameters.

Description

technical field [0001] The present invention relates to the technical field of a method for measuring distance by parallax triangle, in particular to a method for measuring distance by laser triangulation. Background technique [0002] A cleaning robot is a smart home appliance that can perform cleaning work automatically without human operation. It includes a driving wheel module and a power system for driving the cleaning robot to walk on the ground, a cleaning module for cleaning the ground while walking, The control system used to control the robot to clean and avoid obstacles according to the built-in program, and various sensors used to detect the working environment, path navigation, and positioning. When the cleaning robot is cleaning, according to the setting of the built-in program, there are various working paths, such as along the obstacle mode of walking along the edge of the obstacle, the random mode of leaving immediately after encountering an obstacle, and wh...
