Embodiment Construction

[0031] Relating to the detailed description and technical content of the present invention, it is now described as follows in conjunction with the accompanying drawings:

[0032] see figure 1 , is a schematic flow chart of the steps of the three-dimensional distance measurement method of the present invention, as shown in the figure: the present invention discloses a three-dimensional distance measurement method, which includes the following steps: step a): projecting a light group to the surface of an object to be measured (S10); Projecting at least one light group forming a projection plane onto the surface of an object to be measured, the light group includes a plurality of light rays arranged along a straight line with a preset first path function to form detection points on the surface of the object to be measured beamline. Step b): reflecting the light group through a focal point to form an image on a photosensitive memory element (S20); the beam line of the light group...

Abstract

The invention provides a stereo distance measuring method and system. The method mainly comprises the following steps: providing at least one light ray group forming a projecting plane so as to realize projection onto the surface of a to-be-measured object, wherein the light ray group includes a plurality of light beam lines which are respectively emitted according to a preset first path function and parallely emitted along a straight line onto the surface of the to-be-measured object to form measurement points; allowing light beam lines of the light ray group reflected by the surface of the to-be-measured object to pass through the focus of a focusing element and to form a sensing image on a photosensitive memory element; acquiring a corresponding second path function according to the imaging position of every light beam line on the photosensitive memory element and the position of the focus of the focusing element; and calculating the position of each intersection point corresponding to the first path function and the second path function so as to obtain the spatial positions of the measurement points of the to-be-measured object.

Description

technical field [0001] The invention relates to a distance measurement method and system thereof, in particular to a three-dimensional distance measurement method and system using optical image calculation. Background technique [0002] Commonly used distance measurement methods include direct measurement and indirect measurement. In terms of direct measurement, the measurer can directly measure the distance between objects with a ruler, but this measurement method often produces errors due to the different operation methods of the measurer. In terms of indirect measurement, you can use a pole with an instrument to measure, and calculate the distance between the object and the object by calculating the corresponding angle. Although the accuracy of this method is higher than that of direct measurement with a ruler, it is still inconvenient in actual operation due to the limitations of the site and two measurers. [0003] In recent years, many other distance detection method...
