Tutorial (Intermediate level):3D Model Reconstruction with Agisoft PhotoScan 0.8.5 PhotoScan settingsOpen PhotoScan Preferences dialog from Tools menu using correspondingcommand.Set the following values for the parameters in the General tab:Maximum points per photo:40000P1:40P2:2000Write log to file:specify directory where Agisoft PhotoScan log would be stored(in case of contacting the software support team it could be required)Project compression level:6Enable stereo mode:DisabledEnable VBO support:DisabledCheck for updates on program startup:EnabledSet the parameters in the OpenCL tab as following:Check on any OpenCL devices detected by PhotoScan in the dialog and reduce thenumber of active CPU cores by one for each OpenCL device enabled (if your CPUsupports hyper-threading then two active CPU cores per each OpenCL device shouldbe disabled).Add photosSelect the Add Photos... command from Workflow menu. In the Add Photos dialogbrowse the source folder and select files to be processed. Click Open button.Mask photosTo achieve good reconstruction results it is necessary to mask all irrelevant elementson the source photos (background, turntable, accidental foreground, etc.).Open a photo with an irrelevant element in Photo View double-clicking on the photoin the Photo pane.Choose one of the selection tools from the Toolbar: Rectangular Selection forrectangular shape irrelevant elements; Intelligent Scissors–to select irregularshaped area in the photo; Intelligent Paint– to paint the selection with the mouse.To mask uniform background of the image use Magic Wand tool. First, click the Magic Wand button on the Toolbar, then click inside the area to be selected. To change the border of the automatically selected area click inside the area to be addedto the selection.Save the mask clicking Add Selection button from the Toolbar.To alter the current mask use other selection tools together with Add Selection / Substract Selection buttons on the Toolbar.Repeat the described procedure for every photo where background (irrelevantelements) should be masked.Align photosAt this stage PhotoScan refines the camera position for each photo and builds thepoint cloud model.Select Align Photos command from the Workflow menu.Set the following recommended values for the parameters in the Align Photos dialog:Accuracy:HighPair preselection:DisabledConstrain features by mask:EnabledClick OK button to start photo alignment.Select bounding boxThis step is optional since PhotoScan automatically calculates bounding boxdimensions and location. But it is recommended to check if any correction is needed,because geometry reconstruction step deals only with the point cloud inside thevolume.Adjust the Bounding box to the point cloud model using Resize Region and Rotate Region tools from the Toolbar. The whole model should be inside the Bounding box, while any outliers should be left outside the bounding box.Build geometry3D model reconstruction is a computationally intensive operation, it can take a longtime, depending on the quantity and resolution of loaded photos and selected targetquality.Select Build Geometry command from the Workflow menu.Set the following recommended values for the parameters in the Build Geometrydialog:Object type:ArbitraryTarget quality:MediumGeometry type:SmoothFace count:200000Filter threshold:0.1Hole threshold:0.5Click OK button to start building geometry.Build textureThis step could be skipped if untextured model is sufficient as the final result.Set the following recommended values for the parameters in the Build Texturedialog:Mapping mode:GenericBlending mode:AverageAtlas width and height:4096-8192Click OK button to start building texture.Export modelSelect Export Model... command from the File menu.In the Save As... dialog box select the folder for the model to be saved in, print in thefile name and choose preferred file type from the list (e.g. JPEG).Click Save button.In the Export Model dialog indicate the desired export parameters (e.g. Exporttexture). Note that the list of available exporting parameters depends on the selectedfile format.Note: Exported texture will be stored in the same folder as the 3D model with thesame file name (file type is selected by user).。
