I followed this link to visualize multiple .pcd as a video via open3d. It is working fine. However, I am unable to zoom in the generated output.
I have tried to use o3d.visualization.Visualizer.get_view_control() but it doesn't zoom at all.
My code is as follows
import os import fnmatch import numpy as np if __name__ == "__main__": pcd_directory = './2023-04-07-17-17-59/2023-04-07-17-17-59_Clouds' # List all files in the directory files = os.listdir(pcd_directory) # Filter the .pcd files pcd_files = fnmatch.filter(files, '*.pcd') # Sort the .pcd files pcd_files.sort() # Creating an object of class visualizer vis = o3d.visualization.Visualizer() vis.create_window() # Setting the colors of visualizer ropt = vis.get_render_option() ropt.point_size = 1.0 ropt.background_color = np.asarray([0, 0, 0]) ropt.light_on = False # Reading first Pcd and adding to geometry pcd = o3d.io.read_point_cloud(f'./2023-04-07-17-17-59/2023-04-07-17-17-59_Clouds/0000000001.pcd') vis.add_geometry(pcd) # zoom the view ctr = vis.get_view_control() ctr.set_zoom(4) for i in range(1, len(pcd_files) - 550): pcd.points = o3d.io.read_point_cloud(f'./2023-04-07-17-17-59/2023-04-07-17-17-59_Clouds/{i:010d}.pcd').points vis.update_geometry(pcd) vis.poll_events() vis.update_renderer() vis.destroy_window() I have attached my current results and expected results below.
