Tips & How To
CHECK POINT CLOUD ACCURACY
A quick tip on how to check the accuracy of a generated 3D point cloud. Independent control of point accuracy in relation to GPS/GNSS data.
COMBINE CLASSICAL TERRESTRIAL MEASUREMENTS WITH PHOTOGRAMMETRY
3Dsurvey enables you to load and combine any type of point clouds. This video shows a quick and elegant way to import and combine points from terrestrial measurements with photogrammetric point cloud, calculate DSMs and manage volumes. To finish it off, a reporting wizard is used to automatically generate a detailed measurements report
CLASSIFY AND EXTRACT GROUND CONTROL POINTS FROM A POINT CLOUD
3Dsurvey has an automatic DSM/DTM extraction algorithm which precisely separates and removes above-ground objects. Check out this quick video to see how to classify your point cloud for best results. These DSMs/DTMs (bare-terrain models) can be used for anything from environmental analysis and facility localization in urban design to orthophoto generation and DEMs.
CALCULATE TERRAIN CROSS SECTIONS FROM DRONE DATA
Survey-grade profile calculations in seconds. Easily visualize and modify any inputs w/ 3Dsurvey's comprehensive and easy-to-navigate tool set to perform 2D and 3D analysis of your surveyed site purely from drone captured data. 3D points clouds, DSMs, DEMs, contour lines.
HOW TO USE BOUNDING BOX
Bounding box is a very useful visualization functionality that helps you achieve great results, including: - Inspect building plans floor by floor, - Visualize and analyze specific sections of your model, - Isolate specific sections of your model for easier classification and feature extraction.
HOW TO DRAPE AN ORTHOPHOTO OVER 3D TERRAIN SURFACE
While the surface texture information is a great source of information about the terrain, some relationships between the surface texture and the shape of the terrain will be apparent when you drape the orthophoto over the terrain surface. In 3Dsurvey, you can drape an orthophoto over a digital terrain surface (a grid) simply by selecting the correct image from Orthophoto tab and clicking Drape DOF.
HOW TO USE MEASUREMENTS TOOL
A comprehensive measurements tool enables you to inspect 2D or 3D models, point clouds, terrain surfaces, orthophoto. Measure anything from 2D and 3D distances to slopes, height differences and other details.
HOW TO CALCULATE CONTOUR LINES
3Dsurvey software combines thousands of aerial drone imagery to provide the ultimate mining surveying tool. Compared to traditional technology that is labour and cost intensive, drone-based mapping of open-pit mines, quarries and pits by generating point clouds, DSMs and orthophotos adds to safety, cost-efficiency and accuracy. 3Dsurvey has an extremely useful, fast and precise tool that empowers you to generate and calculate contour lines in seconds.
REMOVING OBJECTS FROM CONSTRUCTION SITE DIGITAL SURFACE MODEL (DSM)
Removing objects/obstructions from your calculated DSM (digital surface model) in 3Dsurvey is done by using Flatten function. It is a fast and easy step and helps clean up as well as improve your DSM for further surface related calculation and visualization. Better DSM, better Orthophoto, faster and more accurate Volume calculation and Stockpile/Aggregate measurements.
HOW TO IMPORT LIDAR
Working with LiDAR in 3Dsurvey is as easy as it gets. Just like any other point cloud, LiDAR can be imported and worked with in a matter of seconds. It is a great way to create DSMs, DEMs, Orthophoto maps, topographic maps, terrain studies of larger areas.
CREATE A DRONE MAPPING PROJECT REPORT
Looking to analyze your drone mapping projects or establish a repeatable field-to-office workflow? Project report contains information about imported/processed images, geo-referencing, camera positions, flight characteristics, calculated accuracy, GCP positions, orthophotos, DSMs, processing parameters and error summary.
STOCKPILING & QUARRYING W/ DRONES! GENERATE DETAILED MEASUREMENTS REPORT
Volume and/or profile measurements are key to your daily surveying business. Control aggregate stockpiling, quarrying and mining operations on a daily basis with drone-based data capture and 3Dsurvey field-to-office workflow.
GEO-REFERENCE YOUR MODEL IN MINUTES
GROUND CONTROL POINTS (GCP) ORIENTATION
Ground Control Points are a great way to achieve survey grade accuracy when geo-referencing your models. 3Dsurvey can process images without geolocation. When images have no geolocation, 3Dsurvey uses additional information to locate, scale and orient the model correctly. Ground Control Points (GCP) will both improve your absolute geospatial orientation and place the model at the correct location, scale and orientation.
CREATE NEW 3D POINTS FOR A SURVEY MAP CONNECTION FROM UAV DATA
3Dsurvey with its Point Picking Tool enables you to create new 3D points from existing point clouds for quick survey map connection in any CAD software. Create any number of points on any type of point cloud, assign codes for automatic grouping in CAD or GIS software.
HOW TO USE DRONE MAPPING INSTEAD OF MEASURING WHEEL
In this video we will show you how to use drone mapping instead of measuring tapes, measuring wheel and draw sketches to produce accurate 2D area measurements. This is a great solution for ordering material for your project or producing offer for end customer.
HOW TO USE POINT PICKING IN 3DSURVEY?
How to effectively get specific spot elevation points or 3D points from a point cloud, using the point picking function.
HOW TO USE POINT SNAPPING FUNCTION IN 3DSURVEY
A tutorial showing how to use point snapping to inspect coordinates of a single point from a point cloud.
