Abstract

A method for designing linear laser 3-D scanner includes designing support according included angle between lens optical axis direction and laser beam outgoing plane, firm-jointing a laser beam outgoing flat plate to replace laser beam outgoing plane to mark optimum imaging position and measurement range on said flat plate, using a imaging device micro-move platform under support to accurately measure out included angle between imaging device and optical lens and distance data between imaging device and center of optical lens for confirming design parameter of said scanner.

Description

technical field [0001] The present invention relates to a device for designing a scanner, in particular to a method and device for designing a line laser three-dimensional scanner based on the principle of triangulation. Background technique [0002] The design and production process of the line laser three-dimensional scanner based on the triangulation method is mainly based on the theoretical calculation of the performance index of the scanner, and the parameters and structural parameters of the main components of the scanner are initially selected. Some use optical simulation software for simulation experiments, such as ZEMAX software, to determine whether the requirements are reasonable, whether the selected component parameters meet the requirements of the scanner, whether there is interference in the installation space, etc. [0003] As shown in Figure 1, the parameters to be obtained by the scanner include: 1, the lens focal length f; 2, the angle θ between the optica...
