Embodiment Construction

[0030] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0031] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes ...

Abstract

The invention relates to an electronic device. A laser emitting module can emit line laser and is driven by a driving piece to rotate around a rotating shaft, so that the line laser sequentially covers the whole surface of a to-be-scanned object. By adjusting the preset angle range of rotation, the coverage surface of the line laser can be matched with the size of the to-be-scanned object, and waste of laser energy is avoided. Moreover, for an area with more feature points on the surface of the to-be-scanned object, the controller can control the driving part to slow down the rotating speed, so that the energy of the line laser is concentrated in the area to project more feature points; for an area with few feature points, the controller can control the driving part to rotate quickly due to the fact that the number of the feature points needing to be projected is small, and unnecessary energy waste is avoided. Therefore, on the premise of ensuring the scanning effect, the electronic device needs lower power, thereby effectively improving the scanning efficiency. In addition, the invention also provides a three-dimensional scanning method.

Description

technical field [0001] The invention relates to the technical field of scanning recognition for 3D imaging, in particular to an electronic device and a three-dimensional scanning method. Background technique [0002] Scanning recognition technology has been widely used in mobile phones, vehicles, robots, 3D printing and other fields. Through scanning, information collection and model reconstruction of scanned objects can be performed. In 3D scanning technology, in order to obtain depth data, a surface laser is generally used as a scanning light source. [0003] Although the surface light source can generate depth data, the FOV (field of view) of the surface light source is fixed. Therefore, at different application distances, the area covered by the FOV is different. For example, in short-distance applications, the coverage area is small, so the FOV required by the measured object (such as a human face) is larger, the greater the output power, and the more serious the powe...
