I am trying to convert a depth image (RGBD) into a 3d point cloud. The solution I am currently using is taken from this post where: cx = image center height cy = image center width fx and fy = 25...

I refer the code in http://www.open3d.org/docs/release/tutorial/visualization/visualization.html#Function-draw_geometries and the code as follows: import open3d as o3d print("Let's draw a box...

What is the difference between organized point cloud and an unorganized one? Am I right in thinking that a point cloud is a column of [x,y,z] values? Than what is the difference in the structure o...

As in the title, I want to fit a cylinder to a group of 3D points with Python. This is a nice solution with MATLAB. How can we do it with Python?

I want to read the not reconstructed data from the Stanford Bunny. The point data is stored as several range images, which have to be transformed to be combined to one big point cloud, like written...

I have a 3-D point cloud file with 1 million points that I need to convert into a mesh file in trimesh. The ultimate goal here is to take a point cloud and determine if that point cloud is convex o...

A point-cloud to point-cloud distance can be simply computed using the nearest neighbor distance. The issue is that the nearest neighbour is not necessarily the actual nearest point on the surface ...

I have a cube-shaped point cloud whose x, y, & z-coordinates range from -1.0 to 1.0 unit. #include <pcl/ModelCoefficients.h> #include <pcl/common/common.h> #include <pcl/filters/...

I'm currently trying to play a sequence of ply models through open3d, but I'm having some issues with updating the geometry. Currently only the first image is shown, and the vis isn't being updated...

I'm loading a .ply file using PLYLoader and rendering it using the PointCloud object in three.js. var loader = new THREE.PLYLoader(); loader.addEventListener('load', function (event) { var geomet...

I am trying to create a watertight mesh out of point cloud representing organ contour data from cone beam CT images. My goal is to take two meshes and calculate the volume of intersection between t...

I am loading some PCD data using the PCDLoader, after loading the PCD data successfully we get the Points to add to the scene. I have a circle on top of the PCD points that I created using the Thre...

I'm trying to do some segmentation on a pointcloud from a kinect one in ROS. As of now i have this: import rospy import pcl from sensor_msgs.msg import PointCloud2 import sensor_msgs.point_cloud2 ...

I am trying to find a simple algorithm to find the correspondence between two sets of 2D points (registration). One set contains the template of an object I'd like to find and the second set mostly...

I have an iOS point cloud app and am trying to allow the user to keep adding points to an existing point cloud across multiple sessions. I have a Metal MTKView, overlaid and aligned with an ARView ...

I want to create image out of point cloud (.ply), using open3d. I have no problem with reading and visualizing it but can't find anything on saving it as png or jpg. My code, visualizing cloud: cl...

I have generated multiple point clouds using a RGB+depth video, and would like to visualize the multiple point clouds as a video or animation. Currently I am using Python, part of my code is as fol...

I have some vertices whose coordinates were stored as NumPy array. xyz_np: array([[ 7, 53, 31], [ 61, 130, 116], [ 89, 65, 120], ..., [ 28, 72, 88], [ 77, 65, 82], [117, 90, 72]], dtype=int32...

I am trying to vary the opacity of particles as a function of their distance from a plane. This issue describes my problem, and the answer a year ago was essentially "you can't". Opacity is appare...

can anybody help me with the following problem using Python? I have point cloud matrix got from a virtual camera, its dimension is 320x240x3, which indicates x,y,z coordinates of each point (point...

Is there a library in python or c++ that is capable of estimating normals of point clouds in a consistent way? In a consistent way I mean that the orientation of the normals is globally preserved o...

I am trying to visualize some pointcloud data in Open3d in Python, the screen renders the visualizer but as soon as I try to interact with it, it crashes with the above message. import open3d as...

I have a point cloud from different parts of the human body, like an eye and I want to do a mesh. I tried to use Mayavi and Delaunay but I don't get a good mesh. The points of the cloud are in tota...

I saw the following in the Android documentation for camera2 from API level 23: https://developer.android.com/reference/android/hardware/camera2/CameraMetadata.html#REQUEST_AVAILABLE_CAPABIL...

I have a Point Cloud Library function that detects the largest plane in a point cloud. This works great. Now, I would like to extend this functionality to segment out every planar surface in the cl...
