Description

Technical Field

[0001] The utility model relates to the technical field of visual measurement, in particular to a three-dimensional visual measurement device. Background Art

[0002] Visual measurement, with its advantages of non-contact, high measurement accuracy and fast response speed, is gradually penetrating into many fields such as non-contact online measurement, quality monitoring, cultural relics restoration, equipment manufacturing and industrial production. Among them, structured light 3D visual measurement technology uses images as the carrier of information transmission, based on the principle of triangulation measurement, uses computer digital image processing technology to study the imaging of objects, relies on external scanning drive equipment to complete the acquisition of 3D data on the surface of objects, and completes the 3D reconstruction and measurement process of products.

[0003] For example, a Chinese patent with publication number CN211085122U discloses a three-dimensional visual measurement device, including a measuring table and a measuring body arranged above the measuring table, a fixing frame is fixedly arranged on the side of the measuring table, an electric push rod is fixedly arranged on the upper end of the fixing frame, an adjustment seat is fixedly arranged on the telescopic end of the electric push rod, a bearing seat is fixedly arranged on the bottom end of the adjustment seat, a connecting shaft is fixedly arranged on the upper end of the measuring body, a positioning seat is fixedly arranged on the upper end surface of the measuring table, and two positioning blocks are symmetrically arranged inside the positioning seat. The utility model utilizes the elastic force generated by the spring to make the two matching positioning blocks contact and clamp the object, so as to facilitate the rapid positioning and placement of the object on the measuring table, improve the structural flexibility of the device, and can adjust the height position and horizontal angle of the measuring body according to the measurement requirements, so that the measuring device is more convenient for measurement operation;

[0004] The technical solution recorded in this proposal is to set a spring. When the spring is pushed, the elastic force generated causes the two matching positioning blocks to contact and clamp the object. However, in this solution, only the top of the object is measured, which is not convenient for repeated measurements around the object. When the measurement is not comprehensive enough, the measurement data will be incomplete, which will lead to the inaccurate three-dimensional visual measurement structure of the object.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and a three-dimensional visual measurement device is provided to achieve a purpose with greater practical value. Utility Model Content
