As results were in contrast with the accuracy achieved by using the original fisheye images (front and rear facing images) in photogrammetric reconstructions, an alternative solution to generate the equirectangular projections was developed. Results demonstrate that the direct use of the projection generated inside the mobile phone or with Gear 360 Action Direction (the desktop software for post-processing) have a relatively low metric accuracy. The aim of this work is to test the metric accuracy and the level of detail achievable with the Samsung Gear 360 coupled with digital modelling techniques based on photogrammetry/computer vision algorithms. Render and export jpg or TIFF files that save the maximum information, continue to modify in other modifications software.The Samsung Gear 360 is a consumer grade spherical camera able to capture photos and videos. Other fine tuning stitching methods refer to Mistika VR official tutorials. In this case we add "Edge Point" to camera 5, camera 1, camera 3, avoiding header stitching of five characters. We found that there were characters whose heads were not perfectly stitched so we chose to edit edge points to avoid header stitching. Option chooses optical flow stitch, Use Optical Flow, set Stich Feature as appropriate value and the larger the more overlap parts there will be. Select improve offsets and improve angles in the Position drop-down box to enhance stitching. ![]() Select "Import Stich" in Stitch drop-down box to find the picture folder, import pro.prj files, refer to Insta360 Pro’s engineering description file to automatically stitch into a panorama picture. Here we chose to build a project of 8K.Ĭhoose original pictures of 6 lenses to import, select to import as individual picture ![]() Since the resolution of Mistika VR rendering is consistent with settings in engineering Project, you should set the required resolution beforehand in Project. Refer to Autopano Giga official tutorial for detailed methods Select "Detect" icon on upper left corner to analyze stitching, select "Edit" after analysis, enter the editing interface.ĭetails can be adjusted in editing interface. Open Autopano Giga, click icon to import original images of 6 lenses.Īnalyze images, click icons to open "Image settings", modify "Lens type" to be "Fisheye", "Focal" for 10.57mm, click on "OK" to confirm. "File-Save as templates" is to save it as pts template files for subsequent use "Create panorama" can export jpg ![]() Detailed method refers to PTgui official tutorial. Select lens type as Full Frame Fisheye, setting Focal length for 10.57.Ĭlick Align images for stitching analysisĪdjust level in Panorama Editor, adjust pictures accurately, etc. The original images of 6 lenses are saved for every shoot, so we can put them together with third party stitching software, taking PTgui, Autopano Giga, Mistika VR as examples here. 2.3.3 Stitching by third party software, such as PTgui, etc. ![]()
