Pix4Dsurvey bridges the gap between photogrammetry and CAD. It does so by providing access to the original images and the point cloud through Pix4D’s rayCloud™ to vectorize and extract points, polylines, polygons and catenaries for a shorter time to delivery. Additionally, Pix4Dsurvey supports very large datasets or a combination of many datasets with an optimal experience.
The software expands today’s possibilities by enabling the combination of photogrammetry and third party point clouds such as terrestrial laser scanners.
The main difference is that Pix4Dmapper and Pix4Dmatic are primarily a photogrammetry processing software while Pix4Dsurvey is a tool for vectorization of geospatial data.
Together they cover the complete workflow for transforming the acquired information (images, point clouds) to a deliverable suitable for CAD or GIS software.
Pix4Dsurvey does not calibrate the photogrammetric projects or generate dense point clouds. This is done by photogrammetric software Pix4Dmapper and Pix4Dmatic.
Yes, Pix4Dsurvey can classify point clouds into terrain and non-terrain classes and generate a representation of the ground surface by only using the terrain points. The workflow is the following:
- Terrain filter to classify selected input point clouds into terrain and non-terrain points.
- Grid of points to automate the creation of spot elevations. Using the Smart type creates points only where changes in terrain occur.
- TIN is a seamless set of triangles that represent a surface. When using only terrain points the generated surface is a DTM.
The TIN can be exported as a surface in LandXML file format which is fully compatible with CAD software.
The main difference is that Pix4Dsurvey supports the seamless import of Pix4D projects with accurate results and images.
Unlike CAD software with its focus on design, Pix4Dsurvey provides vectorization and extraction tools and is optimized for handling and manipulation of very large datasets and point clouds.
No. Pix4Dsurvey makes it easier to move from photogrammetry to your CAD product.
Yes, Pix4Dsurvey exports vectorized data that can be seamlessly imported into CAD or GIS software using .dxf and .shp format.
You can import .dxf files into Pix4Dsurvey and use them as a reference and a base for vectorization. Snapping on existing vertices is supported so you can really take advantage of the preexisting data.
Pix4Dsurvey is not included in the Pix4Dmapper or Pix4Dmatic license. You can purchase it separately on the Pix4D online store.
Every Pix4D account comes with a trial of Pix4Dsurvey.
The latest release of Pix4Dsurvey is available on the Pix4D download page.
Pix4Dsurvey runs on both Mac and Windows.
This article covers Pix4Dsurvey’s minimum and recommended hardware specifications.
Pricing plans of the product are available on the Pix4D online store.
Each Pix4Dsurvey license is paired with a Pix4D account. It can run on one computer at a time, but the license is floating and can be used on any computer.
Pix4Dsurvey is a desktop-only application that runs locally on Windows or Mac.
Not today, but this is planned for future releases.
For now, the internet connection is required for the first login.
Pix4Dsurvey allows the import of Pix4Dmapper and Pix4Dmatic projects, as well as independent .las or .laz files. It is also possible to import .dxf files with 2D and 3D objects. The full list of input files is available in this article.
The main output of Pix4Dsurvey are .dxf and .shp files that can be seamlessly imported in CAD or GIS software.
While Pix4Dsurvey requires a projected coordinate system, there is no default system. When Pix4Dmapper project is imported, Pix4Dsurvey will use the coordinate system defined in the Pix4Dmapper project file.
When importing an external point cloud the coordinate system information needs to be written in the .las file.
If you are trying to import the external point cloud in an existing project that was previously created using the Pix4Dmapper project, then the import is still possible. Just make sure that the coordinates of the external point cloud are in the same coordinate system as specified in the Pix4Dmapper project.
If you are importing an external point cloud in an empty project, then you need to make sure the coordinate system is written directly in the .las file.
You tell us! What you can process depends on your system resources, but we’ve successfully tested single file imports of 1.8 billion points on laptops, and more than 4 billion points in total.
