It provides a complete solution for boosting the workflow and increasing productivity when it comes to producing high-quality output. 3DF Zephyr 7 OverviewĪ comprehensive application for generating 3D models from the photos and processing the graphical content with a variety of comprehensive tools for processing the models and producing high-quality output. Zephyr is a powerful application for generating 3D models from the photos and provides flawless rendering features. Please remember that this method cannot be used for accurate scaling and measurements, but it's a quick trick to get rough measurements also from the lite and free version.Download 3DF Zephyr 7 full version program free setup for Windows. The world is now scaled metrically and you can now take metric measurements with the quick measurements tool: Manual input the scale factor 0.41604 and click 'ok':.

Since we know the value of the 'real' distance in metric space, it means that the reconstructed object would need to be scaled by a 1.5 / 3.60539 = 0.41604 scale factor. In this case, the measured distance is 3.60539.Click begin and pick the first and last point of the distance you want to measure:.In the following example, I suppose to know that the door base is 1.5 meters. Suppose you know measurements in meters for the 3D reconstruction.While control points and control distances can be only used in the full version of Zephyr, you can still scale the reconstruction metrically also directly in the Free and Lite version by introducing one known metric distance constraint. Using control points constraints is a much accurate solution that can be done in the full version of 3DF Zephyr. Control points with absolute coordinates positions can be used as constraints during the bundle adjustment to enforce the scaling and the position of the model during the structure of motion itself. This means that to scale the reconstruction metrically and make measurements, you need to introduce at least one distance constraint or control points constraints.

The reconstruction coming from the structure from motion process is always up to an unknown scale factor. Solution home General FAQ How to scale and make measurements with Zephyr Free And Lite
