Imagemaster Photo has ALL the features of the Pro version apart from:

- the ability to register models or point clouds from more than one model space
- the ability to remotely control Topcon's IS Imaging Total Station from a PC

The registration feature is not routinely used in the standard photogrammetry workflow, and in terms of pointclouds from laser scanners, registration is normally carried out using the proprietary scanner software.

Therefore this represents excellent value for money. A summary of the main features includes:

- ability to create automatically 3-D surface TIN meshes from stereo photographs
- construct linework building elevations from photographs
- create and export ortho photographs of elevations or plans
- create RGB coloured point clouds from 3D models derived from stereo photographs
- fast viewing, clipping and editing of laser scan / LIDAR point clouds
- colouring of point clouds using external high-res photography
- meshing and volume calculations from stereo photographs and point cloud data.

Imagemaster works very well with photographs taken from handheld digital photos or images acquired from aerial platoforms (UAVs, kites or aircraft).

Typical applications include archaeology, building conservation, architecture, quarrying and mining, construction surveys, geology and geohazard monitoring and manufacturing. ]]> http://www.terrageomatics.com/pidiscuss/comments.php?DiscussionID=53&page=imagemaster-v22-released http://www.terrageomatics.com/pidiscuss/comments.php?DiscussionID=53&page=imagemaster-v22-released Wed, 14 Jul 2010 13:14:12 +0000 Nick

1. Aim for each node of the polyline to be on the same point on the left and right images. (There is an image correlation tool that helps you do this - see below).

2. Choose polyline nodes on features that are obvious such as high contrast areas such as a light spot against a dark background, the end of a crack etc. Avoid features where small XY offsets could lead to large Z errors such as the corner of a building or a box.

3. Position the crosshair cursor on the left image over the distinct feature (e.g. white spot on a wall) for your first polyline node then using the mouse scrollwheel, move the crosshair cursor on the right image to approximately the same position.

4. Now enable the image correlation tool. This is done by either pressing the [SPACE] bar, or clicking the Binocular icon on the toolbar. Having done this, move the mouse a tiny amount and a red or green circle will appear around the LHS crosshair.

5. A red circle means that no correlation could be made between pixels on the left and right hand images. A green circle means that Imagemaster has found a match and the right hand cursor will snap to wherever the left hand cursor moves. It should now be easy to digitize polyline nodes.

WARNING! Always double check that the image correlation tool has found the correct position on the RHS image of the stereo pair. Occasionally where repeating patterns are present such as brick walls, it may choose the wrong point in which case reposition the crosshairs using the centre scroll wheel.

NOTE! The pixel correlation tool may fail in areas where there is insufficient contrast to work such as dark shadows, overexposed areas or areas lacking in texture. The whole photogrammetry process relies on mapping textural features in the images.

USEFUL TIP! Zoom in to areas of detail on your stereo images to improve the accuracy of polyline digitizing. Pressing the [Z] key is a useful shortcut. Other useful key shortcuts at this stage of the process are:

M - to enable panning (move). Pressing this key again disables panning and allows digitizing to resume.
X - if the left hand crosshair is hard to find, especially in images with a large amount of parallax, this will re-centre the left and right cursors.
C - to close a polyline (e.g. around building openings or if defining a polyline inside which to create a surface TIN mesh).
O - end polyline digitizing and leave it open (e.g. if putting in breaklines to control TIN shape)
Z - zoom, as above and press again to disable zooming.
[Page Down / Up] switch to the next stereo image pair (if applicable to your project). Polylines can be continued onto adjacent pairs.

USEFUL TIP! a very fast way of accurately digitizing polylines is to convert tie points placed during image orientation to physical xyz points on the stereo images. To do this:

1. After completing image orientation calculation (calculator icon), click the "Calculated Coordinates" tab on the results dialogue that pops up.

2. At the bottom of this dialogue box, click the "Register Coordinates" button.

3. Your tie points will now show up as + on the stereo images.

4. For fast digitizing of tie points, click SNAP and POINT on the polyline dialogue that appears on the top left of the stereo screen.

5. Place your polyline nodes by clicking on points on the left hand image only. IM will snap to these on the left and right images. ]]> http://www.terrageomatics.com/pidiscuss/comments.php?DiscussionID=51&page=3d-visualization-news- http://www.terrageomatics.com/pidiscuss/comments.php?DiscussionID=51&page=3d-visualization-news- Wed, 07 Jul 2010 16:49:50 +0000 Topogeo Fabio ]]> http://www.terrageomatics.com/pidiscuss/comments.php?DiscussionID=37&page=rotating-a-model-to-give-a-perfect-elevation-plan-view http://www.terrageomatics.com/pidiscuss/comments.php?DiscussionID=37&page=rotating-a-model-to-give-a-perfect-elevation-plan-view Fri, 21 Nov 2008 13:37:44 +0000 Nick Rotating a model to give a perfect elevation / plan view
If your building or model target is not square to your site coordinate grid (or if you
are using arbitrary unit-less model space), the icons to rotate your model in the MODEL
screen will not give true elevation views i.e. full face-on, vertical plan etc.

A useful tool is to set up a view based on two points that sit on the same plane of
your target, such as the front wall of a building. If you do not have coordinated tie
points that you can select, you can go to the STEREO mode and insert points using the
POINT tool.

This is accessed via the an icon at the far right of the toolbar in the model screen,
or via the menu option View > Rotate > two known points.

1.Is there a possibility to manually insert parameters of camera and lens to Image Master from different calibration software not from Image Calib ?

2.In the documentation is written that for calibration the best solution is to select infinity focusing distance on lens. But when I am calibrating standard 35 mm focal length lens and A3 calibration sheet it is out of focus when I maximize it in image frame or very small in image frame and sharp. So If I have aerial photos with infinity focus Is that a good way to calibrate this lens with manual focus about 1m from the calibration sheet ? I can not print so big calibration form :(

3.I have kite aerial photos taken with different apertures from f2.8 to f 8 and I want to use them as stereo pairs. What aperture I have to choose for making calibration prosess ? If I can not choose the same like in photos. Is that a correct way to choose bigger apertures with better deep of field like f22 or they must be more the same like in photos that I have, so something about f5.6 ?

4.Where I have to manually select point of focus on calibration sheet ? Where must be this point ? In the center square pattern or to have better deep of field in 1/3 length from the nearest marks to the farthest ?

I am new in mobile mapping and I have some questions:

1. Is this technique powerful in maps production at City Level against the Aerial photogrammerty.
2. By using this approach can we produce different map layers both (2d and 3d), like streets, building, districts etc.
3. Advantages of using this technique VS. Aerial photogrammerty.
4. Any useful resources that can be read.

My initial concern is that our photos are not clearly focused enough due to the difficult in keeping still underwater. I cant quite grasp whether I can just use the known distance function with maybe a few pass/tie points or whether we somehow must plig in a ground control point file somehow? Does ImageMaster or PI utilise automatic image recognition of control points or do they always have to be manually placed?

Apologies for the vagaries and I am looking forward to the video tutorials that will be available soon to get me up to speed ]]> http://www.terrageomatics.com/pidiscuss/comments.php?DiscussionID=36&page=you-dont-always-need-tie-points-between-adjacent-image-pairs-to-link-them http://www.terrageomatics.com/pidiscuss/comments.php?DiscussionID=36&page=you-dont-always-need-tie-points-between-adjacent-image-pairs-to-link-them Fri, 21 Nov 2008 13:36:56 +0000 Nick You don't always need tie points between adjacent image pairs to link
them
Sometimes it can be difficult to fine 3 common tie points to link adjacent image pairs
together. The difficulty can be avoided by having coordinated tie points in each pair of
images. These can be measured using a total station or differential GPS. On this basis,
image pairs don't even have to be overlapping if this is not a requirement of your
model.

Remember in the orientation screen, coordinated tie points are differentiated by
having a pink circle around them. ]]>
