    <blockquote> <p>I have a bunch of points lying on a vertical plane. In reality this plane should be exactly vertical. But, when I visualize the point cloud, there is a slight inclination (nearly 2 degrees) from the verticality. At the moment, I can calculate this inclination only. Concerning other errors, I assume there are no shifts or something like that.</p> </blockquote> <p>So, I want to update coordinates of my point data so that they lie on the vertical plane. I think, I should do some kind of transformation. It may be only via rotation along X-axis. Not sure what it would be.</p> <blockquote> <p>I guess, you understood my question. Honestly, I am poor at mathematics. So, please let me know how to update my point coordinates to lie on the exact vertical plane.</p> </blockquote> <p>Note: AS I am implementing this in c++ and there are many programmers who have sound knowledge on these things, I am posting this question under c++.</p> <p><strong>UPDATES</strong></p> <p><em>If I say exactly what I have done so far; I have point cloud data representing a vertical object + its surroundings things. (The data is collected by a moving scanner and may have axes deviations from the correct world axes). The problem is, I cannot say exactly that there is an error on my data or not. Therefore, I checked this with a vertical planar object (which is the dominated object in my data as well). In reality that plane is truly vertical. But, when I fit a plane by removing outliers, then that plane is not truly vertical and has nearly 2 degree inclination. Therefore, I am suspecting that my data has some error. So I want to update all my point clouds (including points on the plane and points which represent other objects) in a way to lay that particular planar points exactly on the vertical plane. Then, I guess, all the points will be updated into their correct positions as in the reality. That is all (x,y,z) coordinates should be updated.</em></p> <p>As an example please refer the below figure. <img src="https://i.stack.imgur.com/ftqT2.jpg" alt="enter image description here"></p> <p>left-represents original point cloud (as you can see, points themselves are not vertical) and back line tells the vertical plane which I fitted and red is the zenith line. as you can see, there is an inclination of the vertical plane. So, I want to update whole my data in the right figure. then, after updating if i fit a plane again (removing outliers), then it is exactly parallel to the zenith line. please help me.</p>

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
