D435i connected to Intel realsense viewer to capture 3D images
D435i is connected to Intel realsense viewer to capture 3D images for 3D reconstruction. The D435i camera is fixed several tens of centimeters away from the object, and the object is placed on a rotating device. The object can rotate on the device. I want to use this method to capture the 3D point cloud model of the object, but the captured image only has the last frame, which cannot be continuously captured to obtain 3D graphics

The RealSense-compatible commercial scanning software tool LIPScan 3D is designed for capturing a small object on a rotating turntable with a single camera, so it may be worth investigating to see whether it meets your needs.

If you prefer an open-source program solution then the RealSense SDK's rs-kinfu C++ / OpenCV example can progressively build up a pointcloud using a single camera by a process of 'frame fusion' and then export the completed model as a .ply pointcloud data file. the ply can then be imported into 3D software such as MeshLab to have further work performed on the data, such as generating a solid 3D .obj model.

rs-kinfu requires C++ programming knowledge to get working though, as it tends to have errors when first run that need to be debugged.
