Three WINDOWS 10 (64bit) applications with different features and functionality are offered and are summarized below:

• RAPID for DJI (Free): Allows input of up to 75 geo-tagged JPEG images of 12 Mpixel format or greater. RAPID will produce a preview orthomosaic, a DEM scaled at X8 of imagery native resolution and an orthomosaic scaled at X4 as output products in GeoTiff format. RAPID for DJI is limited to DJI platforms and sensors.

• REMOTE (Licensed): For larger mapping areas, this module allows input of up to 400 geo-tagged JPEG images of 12 Mpixel format or greater. REMOTE will produce a preview orthomosaic, a DEM scaled at X8 or X4 of imagery native resolution and an orthomosaic scaled at X4 or X2 as output products in GeoTiff format.

• REMOTE EXPERT (Licensed): This module provides full photogrammetric functionality and allows input of up to 1000 geo-tagged JPEG images of 12 Mpixel format or greater. REMOTE EXPERT produces a preview orthomosaic, a DEM scaled at X8, X4 or X2 of imagery native resolution (user selectable) and an orthomosaic scaled at X4, X2 or native resolution (user selectable) as output products in GeoTiff format. This module also will perform processing using ground control points (GCPs). This feature requires imagery pre-processing using the included GCP Tool. The module will generate a 64-bit point cloud of the results in ASCII PLY/XYZ format should the user select that feature.

Feature/Function Benefits

• Orthomosaic preview – facilitates review of acceptable imagery collection at the site, prior to equipment pack-up, by generating the preview in near real time. In many cases the preview will help identify holes in coverage, issues with image geo-tagging and poor quality imagery (blur and other imagery artifacts that hamper proper processing) before you leave the scene.
• Linear and area measurements for overlap verification and scene coverage.
• Selectable scaling of the DEM appropriate for the project requirements. If 1-2’ contours and/or volumetrics are required, then a X8 DEM may be suitable for the quickest turn around and acceptable accuracy. If finer detail is desired, then X4 and X2 DEMs are selected at the expense of processing time.
• Selectable scaling and blending of the orthomosaic for scene feature identification and production of a visually pleasing (minimal to no seamlines) scene.
• DEM and orthomosaic sub-pixel root mean square error (RMSE) of GCPs in horizontal and vertical - facilitates accurate planimetric and 3-D measurements.
• 64-bit point cloud provided for feature classification, editing and DTM generation.
• Robust processing algorithms tolerant of minimal imagery overlap. Allows user to close the loop on operations platform, camera/lens and mission planner to minimize overlaps for high efficiency collects over larger areas, quick processing turnaround times and high quality output.

Please review the operating instructions, run the application on your data sets and provide us feedback on its operation and utility. Should you need additional functionality for larger data sets please contact us for more details on REMOTE and REMOTE EXPERT.

DroneMapper REMOTE: Accurate, Affordable and Accelerated Processing for UAS Remote Pilots

Accurate, Affordable and Accelerated Processing for UAS Remote Pilots
Introducing DroneMapper REMOTE

Pierre Stoermer, CEO - DroneMapper.com



In 2017, DroneMapper will be offering its photogrammetry software to the UAS mapping marketplace, as a Windows application. REMOTE will provide geo-referenced orthomosaics and digital elevation models (DEMs) in the field on your laptop in near real time. Without packing up your UAS mapping platform, simply load your imagery into the application and generate a preview orthomosaic to confirm all went well with the collection. At the site or back at the office you can choose to finish processing at scaled resolutions for quick turnaround or at higher resolutions (REMOTE EXPERT) depending on your client’s needs. A free version, RAPID for DJI will also be offered to allow Remote Pilots operating DJI Phantoms or Inspires to evaluate the software for smaller areas of interest. Features of all offered versions are shown in the table below:



Times shown in table are for the Intel i5-4460, 3.2 GHz (4 cores), 8 GB RAM with 3 of the 4 cores utilized for processing. Your times will be dependent on what laptop hardware you bring to the field.

The chart below illustrates the total time for scaled ortho and DEM production in the application vs the number of images loaded using the hardware described. This is the time to produce an ortho at X4 native and the DEM at X8 native resolutions.



For the 100-acre scene the scaled DEM and ortho will render in about an hour, inclusive of the preview ortho time. For RAPID’s 40-acre scene scaled products are generated within 20 minutes.

REMOTE provides very quick feedback on the quality of the collection using the data Preview function and accurate scaled output products that are usable for applications requiring topography, contours and volumetric estimates.

REMOTE EXPERT adds additional functionality in output product scale selectability, use of ground control for absolute mapping accuracy and the ability to map much larger areas.

Please contact us for additional information on our RAPID and REMOTE software products.

Geo-spatial Accuracy and Optimal DEM Construction Utilizing Nadir & Obliques - 8/24/16

DroneMapper Labs: Geo-spatial Accuracy and Optimal DEM Construction Utilizing Nadir & Obliques - 8/24/16
Pierre Stoermer, CEO - DroneMapper.com
 

This post addresses two topics 1) expected positional accuracy using ground control and 2) utilizing a combination of nadir and oblique images for optimal DEM construction.

Geo-spatial Accuracy:

Here we report on a set of recent imagery collections utilizing primarily UAV platforms (one manned platform included – Project L) with varied collection sensors. In each case well surveyed ground control was used in the processing of the DEM and orthomosaic. In each of the DEM/ortho sets the position of the control was compared to the surveyed coordinates to compute horizontal and vertical root mean square errors (RMSEs). All measurements were accomplished utilizing Global Mapper, version 16.2. The table below illustrates seven data sets with RMSEs computed.

Examples of DroneMapper Ortho & DM Ground Control Geo-spatial Errors (RMSE)


ProjectScene Area (sq. Km)GCP NumberImagery GSD (cm)Camera UsedAverage Horizontal Error (RMSE - cm)Vertical Error (RMSE - cm)
L1802714UltraCam Falcon prime2.857.9
B1.15223Sony a51001.33.5
CB0.5674.7DJI FC-3003.23.6
WE0.6685.9Sony NEX-5R4.345.21
TB-10.5655.6DJI FC-3502.33.3
TB-20.9457.4DJI-FC-3503.64.66
McB0.8876.2DJI FC-300X2.25.2

The data sets include a manned aircraft using Vexcel’s UltraCam Falcon prime (Project L), two fixed wing UAVs using Sony cameras (Projects B and WE) and four DJI quad-copter UAVs using the FC series of sensors (Projects CB, TB-1, TB-2 and McB). In all cases except one, Project B - vertical error, the horizontal and vertical RMSEs are sub-pixel (compared to the native GSD).

When we average the four DJI project horizontal and vertical errors as a percentage of GSD we see that one could expect an error of one-half pixel horizontal and three-quarters pixel vertical. In terms of absolute map accuracy with 95% confidence one could expect 1.2 pixels horizontal and 1.5 pixels vertical. So for you DJI operators, if your application requires absolute vertical accuracy of 3”, plan on imaging at 2” pixel GSD or less with well surveyed control.

Nadir and Obliques for DEM Construction:

A set of nadir and oblique images were collected for a mining operation, interested in accurate volumetric estimation. The accuracy of the estimate is dependent on the pile size and vertical error. We used a DJI Phantom 3 flying at an AGL of approximately 200’ (GSD: ~ 1”). Four (4) existing ground control points (GCP) were utilized for precise geo-referencing of the ortho and DEM. An example GCP from the ortho along with the ground truth position (black labeled dot) is illustrated in Figure 1.


Figure 1: Typical Ground Control Point

In this case, GCPs are used for referencing the stockpile surface to a bare ground DTM in order to accurately measure temporal changes. The mining operation utilizes an above pile conveyor system for stockpile distribution. For traditional nadir only image collections the conveyor obscures the pile surface, making accurate surface definition below it difficult. We utilized both nadir and oblique images in order to see the pile surface that is typically obscured with nadir only images. Figure 2 shows a point cloud of one of the stockpiles along with the conveyor structures overhead.


Figure 2: 3-D Model Rendering of Stockpiles – Conveyor Structures

The next illustration, Figure 3, shows the DEM of a portion of the stockpile along with the conveyor system overhead. The DEM/ortho processing was completed utilizing a GPU within one hour of imagery input. DEM resolution used was X4 of native imagery and ortho was X2. As a comparison Figure 4 illustrates the same section of DEM processed at a different time using only nadir images. Full native resolution was used in the processing of the nadir only images at that time as compared to Figure 3 processed with resolution scaling.


Figure 3: Nadir & Obliques - Section of DEM Showing Feature of Interest with Conveyor Overhead


Figure 4: Nadir Only Images – Same Section of DEM with Conveyor Previously Processed

One can see the crispness of the structure (Figure 3) and lack of blobbing/noise (Figure 4) that the use of obliques contributes. This makes extraction of the structure and rendering of the surface below it cleaner with less surface errors that contribute to volumetric estimate inaccuracies. When the conveyor structure is carefully removed from the DEM an accurate rendering of the stockpile surface results as illustrated in Figure 6.
