Q:
How can I use the "Manual Point Alignment" function in Absolute Orientation?
A:

Aligning corresponding points: The grid needs to be in the same viewport as the photo image. Use the ALT key to zoom in on a local area. Select corresponding points with the left mouse button. Press the space bar to switch between the grid and the photo. When there are at least 6 pairs of corresponding points, click {Align} - corresponding points alignment.

Q:
By saving the color point cloud as an ASC file, what information can we obtain?
A:

When opening the ASC file with a text editor (e.g., Notepad), you can read three types of core data of the point cloud: three-dimensional spatial coordinates (x, y, z), normal vector parameters (i, j, k), and normalized color information (r, g, b).
