Align pointcloud data to rgb data

[JLH]

Hi! I got a problem when I was using realsense D435i camera.

I recorded only the generated point-cloud data and RGB image WITHOUT alignment.

It turns out to be: my point-cloud data (or the depth image generated by point-cloud) has the same pixel number with RGB image, while the vision field is different. As shown in attached file, left is the point-cloud plotted, middle is the depth image generated by point-cloud, right is the RGB image.

I'm wondering is there any method that can align the point-cloud with RGB image from my stage. Since the method I can find on google is all about aligning using the RGB and depth frame, while I didn't save those frames.

Thanks anyone for help!!!!!!!!!!!
