Agisoft - Very basic introduction

Agisoft - Very basic introduction

Welcome to this simple tutorial about the basics of Agisoft Photoscan. To be able to work efficiently, you need to download the pre-configured assets from my website and photos and have agisoft photoscan installed on your PC.

Open agisoft

1 We begin with a very simple scene consisting of a series of images taken from a tree trunk in a forest. This material offers perfect material for photogrammetry as it is very random and has many different colours, textures and details.

Image folder

2 First copy the images to your PC and then drag and drop them into the Photos tab in the agisoft interface.

3 As you can see, all images are loaded. The next step is to click on the workflow and align photos.

4 Set the accuracy to medium and in advanced mode, do not change anything after clicking OK, agisoft edits the images.

5 After the editing is finished, a simple point cloud is left in the viewport, if everything went well, you should let this point cloud be displayed in the viewport.

As you can see, the point cloud already imitates the trunk roughly.

6 The next step is to create a dense cloud of points to do this, go to the workflow and click on build dense cloud.

click on build dense cloud

7 In the dense point cloud options, set the quality to medium depth filtering to medium to moderate filtering.

set the quality then click OK

8 After you have clicked on OK, agisoft starts to edit the detailed point cloud, this may take a while.

9 After agisoft has finished editing the dense point cloud, please click on the symbol in the middle with the colored dots in the viewport. The already highly detailed, dense point cloud is viewed in your scene.

10 The next step is to build the mesh to do this, go to the workflow and click build mesh in the options, leave everything on middle and click OK after processing is complete, you can click on the small triangle icon and you will see a tessellated and colored preview presentation of the final mesh.

11 Of course, all this mesh is a bit muddy, so the next step is to build a pixel-based texture to do this, click Workflow and click Create texture lets the settings as they are and click OK to start processing paragraph.

12 After the editing is complete, you can click on the small triangle with a texture that is symbolized on it, then you will get a preview of the interview part of the texture, as you can see is very detailed and very realistic.

13 You can click into the viewport to rotate the object, but right now this is the first step to understand agisoft photoscan, so we can see more things in the next tutorial.
