You may also pan the view by keeping left control pressed and moving the mouse cursor. For this tutorial, we will use the preset mode with Close Range/Default settings.īefore moving to the next step, let’s learn the basics to navigate the scene, which is rendered at the centre of the screen (7).īy default, you can navigate the scene in orbit view mode: while hovering the mouse cursor on the scene (7) hold left click and then move your mouse to look around. To zoom in/out simply use the mouse wheel. Before doing that though, it’s necessary to tell Zephyr which settings to use. Here’s a brief explanation of what will happen: Zephyr will analyze each image and find the features of the images (points of interests that the computer can understand) and compare each image with (usually a subset of) the other pictures: this is done to set the cameras in the correct position. You are now ready for the first computation phase. This topic won’t be covered in this tutorial, so just click “ Next“. You will be now taken in the “ Camera Calibration Page” Window. Protip: advanced users can add a previously generated manual camera calibration (if available) by checking the option in the lower left corner of this window. Click it and you’ll get to the next window, which will allow you to assign camera calibration parameters to loaded pictures. The “next button” (5) will now be clickable. Select all the images you previously extracted and then click open (or drag and drop images directly from the windows explorer) Click on the “plus sign” (4) and browse to the directory where your dataset is located. ![]() This next window is the “ Photo selection page“, in which we need to add the photo that we want 3DF Zephyr to process. Another option (checked by default) allows Zephyr to download camera calibrations where available: we suggest to leave this option on – although Zephyr is completely autocalibrated, the online camera calibration can speed up the first phase and help with some fisheye lenses. Leave them unchecked as in this tutorial we’ll walk you through both those steps. Protip: there two options in the lower left corner of the Project Wizard (3) that allows you to automatically compute the dense cloud and the surface. To continue, in the “Project Wizard” screen click “Next” in the lower right corner. You can learn more about the most common guidelines on this quick guide titled “ how to acquire pictures for 3DF Zephyr“. This phase is critical for the scene reconstruction, so please feed 3DF Zephyr a good dataset: blurred images and dataset with no overlapping pictures are examples of bad data for 3DF Zephyr. The “Project Wizard” (3) screen will appear which will guide you through the process of importing your pictures. To create a new project, click “Workflow” (1) and then “New Project” (2).
