![[Case Study] Comparison of Scanning Accuracy between 3D Laser Scanners and X-ray CT Devices](https://image.mono.ipros.com/public/product/image/ef7/2000513779/IPROS74824299017178898123.jpeg?w=280&h=280)
I will introduce a comparison of the scanning accuracy between 3D laser scanners and X-ray CT devices.
When performing reverse engineering, it is necessary to obtain point cloud data of the sample's shape, and the major methods for data acquisition are 3D laser scanning and X-ray CT scanning. Each method has its advantages and disadvantages, but which scanning method offers better accuracy (i.e., higher shape reproducibility)? In this case, we will verify the extent of error and distortion in the scan data from the 3D laser scanner and the X-ray CT scanner based on the dimensions measured by a three-dimensional measuring machine. The procedure is as follows: 【Step 1】 Obtain point cloud data of the sample's shape using a 3D laser scanner. 【Step 2】 Obtain point cloud data of the sample's shape using an X-ray CT scanner. 【Step 3】 Conduct dimensional measurements using a three-dimensional measuring machine. 【Step 4】 Extract dimensional data from the point cloud data in Steps 1 and 2, and compare it with the dimensional data from Step 3.
