Problems solved by technology

[0004] However, such "contact" systems with rigid or articulated arms are very bulky and difficult to move
In fact, they are completely inappropriate for 3D scanning or inspection of objects that cannot be moved from their original location (such as archaeological finds)

Embodiment Construction

[0017] refer to figure 1 , the device 1 for three-dimensional or 3D scanning of objects according to the invention is manual and comprises detection means 3, 5, 7 adapted to provide orientation information of the device 1. The detection means 3, 5, 7 comprise at least one inertial and / or magnetic sensor, in particular an accelerometer 3 with three orthogonal sensitivity axes, a magnetometer 5 with three orthogonal sensitivity axes and a magnetometer with three orthogonal The sensitivity axis of the gyroscope7. In more detail, the accelerometer 3 allows the measurement of the dynamic component or variation of acceleration as well as the continuous, or static, component. The magnetometer 5 can measure the directional versus and strength of the magnetic field in which it is immersed. The gyroscope 7 allows to detect its own angular rotation speed.

[0018] Orientation information includes data about the roll, pitch and yaw of the device 1 .

[0019] In addition, the three-dim...

Abstract

A device (1) for three-dimensional scanning of objects is described, said device comprising detection means (3, 5, 7) adapted to obtain orientation information of the device (1); optical means (9) adapted to obtain information about planar information on the position of the device (1) in the first reference plane of the optical means (9); and processing means (11), adapted to obtain from the detection means (3, 5, 7) and from the optical means (9), respectively Orientation information and plane information, and for the purpose of obtaining a three-dimensional image of the object, this information is processed to obtain an estimate of the position of the device (1) on an axis substantially perpendicular to the first reference plane.

Description

technical field [0001] The present invention relates to equipment, systems and methods for three-dimensional scanning, and in particular to equipment, systems and methods for three-dimensional (or 3D) detection of physical objects with arbitrary geometric structures. Background technique [0002] Many measuring instruments are known which can copy or reproduce the three-dimensional contours of real objects with complex shapes. These instruments are called "3D scanners" and are used in industrial design, quality control, biomedicine, and other applications that require digital copies of real objects. Such a system may require the use of different technologies, each with specific limitations, advantages, and costs. According to a well-known and established classification, they are divided into two macrofamilies: "contact" systems and "contactless" systems. [0003] "Contact" 3D scanning systems probe the outer surfaces of objects through physical contact. The structure of t...
