The next step is to generate the control points, which indicate features that match between pairs of images. Enter "Normal (rectilinear)" for the lens type and 1 for HFOV in the dialog. To start a stitch with Hugin, load the images by dragging-and-dropping them into the Photos window. The software can be downloaded from the Hugin website. While Hugin is easy to use for simple panoramas, it's pretty confusing for more complex projects, which is why I've written this. If ICE doesn't work for you, the open-source Hugin panorama photo stitcher is much more flexible and provides many more options. If ICE works, it's super-easy, but it doesn't have any flexibility if you run into problems (as I did). You simply import the photos, click Stitch, and save the result. The easiest way to stitch together photos is with Microsoft's Image Composite Editor (ICE). The set of images used to generate the die photo. In the process I learned the importance of overlap, and Hugin worked much better when I tried again with a denser set of images. As a result, this article describes a fairly difficult stitch. Some of them overlap substantially, and some. This will make it much easier to figure out which photos are overlapping neighbors when stitching them together.įor this article, I used the set of images below. Give the images structured names according to their grid position: 11.png, 12.png, 21.png. The quality of the input photos is also important - make sure the die is level so you can get sharp focus across the whole image. Skimping on the overlap may result in hours of manual work later. Use more overlap than you think necessary - at least 30% is good. The key to success is pictures with substantial overlap, so the software can figure out how to combine them. It's much easier if the microscope has an X-Y stage to precisely move the die for each picture. (The box on the right of the microscope is the light.) A metallurgical microscope shines the light from above so you can view opaque objects such as chips. I used an AmScope metallurgical microscope like the one below. The next step is to take photos of the die through a microscope. The MC6820 chip with the metal lid popped off to reveal the silicon die.
