Problems solved by technology

However, this method has great limitations. The accuracy of the three-dimensional space data obtained by image processing is far inferior to that of laser measurement in large scenes exceeding 5 meters.
[0005] Moreover, devices that scan, measure or acquire data from other 3D objects, such as performing 3D reconstruction, are difficult to balance between speed and accuracy

Embodiment Construction

[0047] The present invention will be further described below in conjunction with the accompanying drawings.

[0048] The principle is as follows:

[0049] Such as figure 1 As shown, the device includes a measuring head, a rotary table, a controller, an image processing module, and a computing unit (computer, mobile phone, tablet, embedded computer).

[0050] Obtain three-dimensional laser point cloud: the laser transmitter in the measuring head is used to emit high-frequency pulsed laser. When the laser hits the target object, it is detected by the laser receiver and records the time difference before and after, so as to determine the scanner to the target object. surface distance;

[0051] The calculation unit sends control commands to the motor control module through the synchronous control module, the motor controller controls the first motor to control the rotation of the mirror so that the laser beam can perform line scanning in the vertical direction, and the synchro...

Abstract

The invention provides a color three-dimensional laser scanner and a three-dimensional color point cloud scanning method. A three-dimensional color point cloud scanning system of the invention uses the combined type technology of an ordinary light and a laser for scanning the outline structure and color texture of a space or object, so as to obtain and convert spatial coordinate information and color texture information of the space or object surface into a digital model containing both the coordinate information and the color information, and the digital model can be applicable to industries of machinery manufacture, home decoration design, construction and civil engineering, cultural heritage conservation, game development and the like and other related industries. The invention is designed for one time molding, requiring no post-processing, 360-degree panoramic modeling can be done within a minute, the whole process is automatic and quick, and the accuracy of measurement data is also ensured.

Description

technical field [0001] The invention relates to the scanning field, in particular to a color three-dimensional laser scanner and a three-dimensional color point cloud scanning method. Background technique [0002] The application fields of 3D scanning technology are very extensive, and there is a great demand for 3D models in industries such as machinery manufacturing, home decoration design, architecture and civil engineering, cultural heritage protection, and game development. [0003] There are currently several types of optical scanners, one is to measure three-dimensional space through point laser or line laser, but this kind of scanner can only obtain three-dimensional space information, and cannot obtain color texture information of space or object surface. If you want to add color texture information, you must obtain color pictures through professional digital equipment, and obtain a color 3D model through texture mapping. Due to the deviation, the obtained color 3D...
