研究目的
Investigating the method of three-dimensional reconstruction based on line laser rotation scanning to achieve accurate three-dimensional measurement of objects.
研究成果
The proposed three-dimensional reconstruction method based on line structured light is effective, with a relative error of about 1%. The system is simple, convenient to use, and low in cost, making it suitable for various applications.
研究不足
The method may have limitations in reconstructing large objects due to the cost and speed of the devices used.
1：Experimental Design and Method Selection:
The system is designed with a rotating platform, a laser transmitter, and a monocular camera. The axis-eye calibration algorithm is used to register the point cloud in the same coordinate system.
2：Sample Selection and Data Sources:
A statuette of David is used as the experimental object. Images of the object are captured from different angles using the rotating platform.
3：List of Experimental Equipment and Materials:
SCA750-60gm model camera by Basler, with a resolution of 2 million pixels and a focal length of 12mm lens. A line laser is used for testing.
4：Experimental Procedures and Operational Workflow:
The camera is rotated on the platform to capture images of the target object. The light strip center is extracted, and the camera is calibrated to solve the internal and external parameters. The structured light plane is calibrated, and the point cloud is reconstructed.
5：Data Analysis Methods:
The point cloud data is displayed in the cloudcompare software for analysis. The actual value of the David statue's distance between any two points is compared with the calculated value for error analysis.
