I have clone the depthai-python repo into my local pc. My goal as of right now is to visualize the pointcloud by using one of the scripts from the github repo. However the script does open the open3d window but it stays white, the top left corner says "open3d not responding". Here is the script that I am running: import open3d as o3d
import numpy as np
import depthai as dai
import queue
q = queue.Queue()
pipeline = dai.Pipeline()
PointCloud = pipeline.create(dai.node.PointCloud)
pcd = o3d.geometry.PointCloud()
vis = o3d.visualization.VisualizerWithKeyCallback()
vis.create_window()
with dai.Device(pipeline) as device:
coordinateFrame = o3d.geometry.TriangleMesh.create_coordinate_frame(size=1000, origin=[0,0,0])
vis.add_geometry(coordinateFrame)
while device.isPipelineRunning():
inMessage = q.get()
inColor = inMessage["rgb"]
inPointCloud = inMessage["pcl"]
cvColorFrame = inColor.getCvFrame()
if inPointCloud:
points = inPointCloud.getPoints().astype(np.float64)
pcd.points = o3d.utility.Vector3dVector(points)
colors = (cvRGBFrame.reshape(-1, 3) / 255.0).astype(np.float64)
pcd.colors = o3d.utility.Vector3dVector(colors)
vis.update_geometry(pcd)
vis.poll_events()
vis.update_renderer()
vis.destroy_window()
Another issue I am encountering is: inMessage=q.get() whenever I am running the script pointcloudcontrol.py and visualize_pointcloud.py.
