For StereoCAD users · October 2026 release
StereoCAD changes profile: from stereo drawing software to a complete, automatic system that goes from the raw dataset to the cartographic deliverables.
Version 1.4.13 · November 2026
Image orientation: stronger ground control, whole images, lenses taken into account, results that start from what succeeded.
The residuals on the points go down. Without points the reference stays the GNSS. The box Ground points rule the block starts checked.
Orientation takes longer. A reduction can still be asked for in Advanced.
On DJI drones the start is the factory calibration written in the images.
Readmit them brings them back.
A new project no longer inherits the files of the previous one, and a coordinate file with no measurements no longer comes back on its own to block Start.
Every result ends with what to address, each with the thing to do.
Version 1.4.12 · November 2026
Drone flights with nadir and oblique images, from the navigation surface to the ground control points.
The stereo and the mark always have a reference elevation.
From Pix4D projects the ground control points come in by themselves, with their measurements on the images.
Visit point, the Overview, continuous roaming and the + and - keys work here too.
Rotation brings back the view from above turned like the stereo, keeping the scale and the mark.
The mosaic and the photographs use the nadir images only, on a smoothed surface. The mark's elevation does not change.
The count and the time estimate say so before it starts.
The rubber band ends on the centre of the mark and Esc holds the stereo on flights on the diagonal too. Point clouds are no longer imported: work on clouds belongs to StereoCloud3D.
Version 1.4.11 · November 2026
A large stereo and a plan you can read from near, with the checks and exports surveyors asked for.
The wheel enlarges from the first notch, and the keypad's + and - zoom by two at a time, also when looking only into the stereo.
No computing and no waiting: the plan uses the same images as the stereo, laid on the navigation surface.
The fields take the point where you are, so the hand can reach the window without moving it.
On an imported orientation too, with no new triangulation. Lists with a decimal comma, or North before East, are read correctly.
Nadir and obliques in one project, and with BINGO a camera per folder. Stereo pairs keep nadir and oblique images apart.
From the DTM row of the dense cloud panel, at the grid step you choose.
Version 1.4.10 · November 2026
No more getting lost on the model, also for who comes from the old StereoCAD64.
On every project, those made earlier too: the surface and its photographs are ready before you start working, and before the stereo starts.
Held down, the plan and the stereo follow the mouse. The map shows the photographs and the ground control points, and back on the plan the mark stays where it was taken.
Ctrl+G takes the plan and the stereo to the point, with the stereo off too.
You can look only into the stereo, as in StereoCAD64; what you need to know is said inside the stereo itself.
Version 1.4.9 · November 2026
Right heights even when the GNSS of the images and the ground control points disagree.
When the control points are off by more than twice their accuracy, the GNSS was weighed too much: the program widens it by itself and adjusts again. On 224 images with 44 check points the height error went from 9.1 to 3.3 cm; with a good GNSS nothing changes.
Image orientation reopens with the choices of the last run, also when its block was not imported: a box turned off no longer comes back on.
An image left without tie points after the adjustment is no longer written as oriented.
Version 1.4.8 · November 2026
What your ground control points are really worth, and the images the triangulation leaves out brought back.
Each ground control point is left out in turn and measured by the block adjusted without it: the real error where there are no points, beside the residuals of the control and check points.
As other programs do: the residuals on the points go near zero, and the cross-validation says the real error. It helps when GNSS and points disagree; run both and keep the lower cross-validation.
When the triangulation leaves out images with GNSS, the result says so with the extra time and searches them again with the calibrated camera at a click.
With the ground control points window open, importing a block with fewer images could close the program.
Version 1.4.7 · November 2026
A steady 3D view with large dense clouds, and a stereo you can tell apart at a glance.
With large dense clouds the program could close while it loaded a new piece of the cloud in the 3D view. Corrected.
The stereo bar stands out from the others, so it is found at once.
If the 3D window is closed from the Windows taskbar or with Alt+F4, stereo turns off and a message says why, as in StereoCloud3D.
Version 1.4.6 · October 2026
A 3D window you can resize, a Stereo menu in order, and a triangulation that no longer falls over on big photos or mixed heights.
Stereo › Stereo monitor › Resizable 3D window: with quad-buffer stereo the 3D window and the main window move and resize like any other. Off by default.
The first line says whether stereo is on and on which monitor; layouts and checks are in two submenus, as in StereoCloud3D.
Photos are worked together only as far as the free memory allows; a photo that still does not fit is lost alone and the calculation goes on.
The GNSS heights of the images can be declared on the ellipsoid and brought to sea level with the geoid; the report warns when the focal length drifts, the usual sign of mixed heights.
Version 1.4.5 · October 2026
Photos the triangulation used to leave out come back, ground points are easier to read, and StereoCAD64 projects open from the File menu.
A strip not joined to the next is oriented on its own GNSS; a single photo starts from its ground points or GNSS. A photo that would land far from its GNSS is refused, and the report says which ones came back.
In the point window the crop moves by dragging with the right or middle button; every point nearby shows its name next to its mark, without overlapping.
The .scad file opens as a new project with images, orientations and drawing; the original is not changed. The same button is on the welcome screen.
Previews with the same names as the photos are told apart, code tables in text format load as libraries, and the right button in the 3D view gives the properties of a drawn line.
Version 1.4.4 · October 2026
Drawing driven by the stereo with no edge, ECW images and Metashape projects in degrees read as they come, and support one click away.
During a drawing command the mouse moves the mark and the plan follows with no edge, also in the 3D view; the click takes the mark's exact point. F8 switches it off.
At the import and in the triangulation the ECW images are converted once into TIFF in the project, with a progress bar.
A Metashape XML in WGS84, usual for drone flights, goes into the StereoCAD project's system with its markers, heights brought above the sea.
A picture of the window, the log and your comment in one file to attach to an e-mail. After a crash StereoCAD asks whether to send the report to MENCI Engineering. In Stereo AI, Copy under every answer.
Version 1.4.3 · October 2026
Plan, Overview and stereo that always agree, a photo background in seconds, and calm water that stays flat in the dense cloud.
The mark never stays behind; a short pause on the Overview hands it the stereo, and the status bar says why the mark stops where no pair sees the ground.
From the keyboard, the status bar or Stereo > View; the chosen zoom stays when the pair or the height change.
On opening, a light surface measured on reduced photos, with a mosaic of the photos as plan background; the dense cloud is made only when you ask for it.
Marshes, ponds and canals become flat at their measured level, with points marked as water (class 9). Optionally Stereo AI looks at a reduced mosaic of the photos and says where the water is: nothing is flattened in a town.
Version 1.4.2 · October 2026
The free zone of the mark sized to the way you work, and a log that says which graphics card draws.
Stereo > View > Free zone size: larger, the plan scrolls only near its edges. Saved in the project; the Scroll button still switches it off.
The log says which card draws the program and, when it is the integrated one of the processor, what to do to use the dedicated card.
Version 1.4.1 · October 2026
Orientations from your own table, one more satellite read without its RPC, a way to have the others added, and a fix.
In the BINGO / OPK import, the focal length and the pixel from the camera's data sheet: the image size is read from the images.
Columns in any order, decimal comma, gon or radians: Stereo AI shows a preview, and after your yes writes the file and fills the Import window. The program copies the numbers.
Level 1B1 views in JAXA's CEOS format: the four detector strips of each view become one straightened image.
With your consent, only the metadata files leave, never the images; the next version reads that satellite.
The labels of contour lines no longer close StereoCAD.
Version 1.4.0 · October 2026
Free Stereo AI at hand in every window, satellites read with the rigorous model, the accuracy report inside the program and a clear license agreement.
The text can be read again from Help › License status and on this site, with the license and maintenance contract.
You open and look at your projects, without changing, saving, exporting or printing them. Renew with the new year's fee and the same key returns to full use.
Its answers use no AI credits. Every main window opens the assistant with a question about that window already written: complete it and send it.
When a project opens, Stereo AI looks at the data in its folder and proposes the work it allows, with the reason and the products; a click opens the command.
A new format is learnt from the delivery's documents or from the supplier's public documentation, and checked on the scene. Pléiades, SPOT 6/7 and SpaceEye-T also without RPC; tiled Pléiades as one scene.
A laser survey or another DSM is imported as a reference and compared with the project's DSMs: spread, offset, plan shift, difference map and a report for the client.
Each scene is paired with the one that gives the right depth, not with a view of the same pass.
At the first start toolbars and windows do not cover buttons, the plan view or the right column, and stay on the screen.
License status and messages in six languages; the Stereo AI window also in French, German and Spanish.
The changes
You load the dataset and the system takes it to the deliverables fully automatically, with stereo control at every stage.
StereoCAD recognises everything the client supplies: images, accessory files, metadata, previous orientations, calibration certificates, control points and any other information useful for aerial mapping.
The software evaluates the dataset and proposes the best solution for the best result with the information available. You choose the target; the system adjusts the dataset.
On the adjusted dataset the system proposes the possible outputs. The DSM is derived from the point cloud, and so are the DTM and the contour lines. The true orthophoto needs no mosaicking and no stitching.
The 3D mesh model of the surveyed object comes from conventional aerial photogrammetry, drone or terrestrial photography.
Every result can be checked and accepted in stereo.
What stays
Automation does not replace stereoscopy: restitution stays at the highest level possible, in an extremely powerful drawing environment, built for the most demanding stereo operators.
Datasets already oriented by others still go straight to stereo, as before.
What is added
