Abstract

The invention provides an object measurement method and system and a computer readable storage medium, which are used for realizing a multi-degree-of-freedom flexible measurement mode in a measurement process on the basis of keeping high-precision three-dimensional measurement quality, so that the advantages of high efficiency, high precision, high robustness and the like can be shown. The method comprises the steps that a handheld sensing device collects images of an object to be measured at different visual angles under handheld operation of a user, the handheld sensing device is provided with a sensor needed for collecting the images, and the handheld sensing device is obtained by combining handheld operation configuration under the human engineering mechanics requirement; a user terminal acquires an image from the handheld sensing device according to local area network communication connection between the user terminal and the handheld sensing device, and converts the image into point cloud data through data processing; and the server acquires the point cloud data from the user terminal according to the UDP communication connection between the server and the user terminal, performs feature analysis and extraction on the point cloud data, and displays the point cloud data through a three-dimensional visualization engine.

Description

technical field [0001] The present application relates to the field of measurement, and in particular, to an object measurement method, system, and computer-readable storage medium. Background technique [0002] In recent years, with the development of AR / VR and MR (Mixed Reality) and other related technologies, 3D measurement technology has gradually become a research hotspot, especially in the fields of autonomous driving and smart cities. [0003] At present, 3D measurement technology is defined as: measuring the object to be measured in all directions and determining the relevant measurement data of the object to be measured. The measurement principle can be divided into four aspects: ranging, angular displacement, scanning, and orientation. According to its 3D measurement technology The field of principle subdivision includes contact and non-contact. Among them, non-contact 3D measurement technology mainly relies on optical 3D measurement technology. After decades of d...
