Toolbox
Generate Point Cloud
Computes 3D points from
stereo pairs and outputs a point cloud as a set of LAS files.
The tiling of the LAS
files is based on 1,000 by 1,000 ground spacing. The points in each LAS tile
are computed by selecting pairs, based on user-defined criteria, and filter
points from the selected pairs. The input of this tool is a mosaic dataset that
contains a stereo model. The output of this tool can be used to generate a
digital terrain model (DTM) or a digital surface model (DSM).
يحسب النقاط ثلاثية الأبعاد من أزواج الاستريو
ويخرج سحابة نقطية كمجموعة من ملفات LAS.
يعتمد تبليط ملفات LAS على
تباعد أرضي يبلغ 1000 × 1000. يتم حساب النقاط الموجودة في كل لوحة LAS عن
طريق تحديد الأزواج ، بناءً على المعايير المحددة من قبل المستخدم ، ونقاط التصفية
من الأزواج المحددة. مدخلات هذه الأداة عبارة عن مجموعة بيانات دمج الصور تحتوي
على نموذج استريو. يمكن استخدام ناتج هذه الأداة لإنشاء نموذج تضاريس رقمي (DTM) أو
نموذج سطح رقمي (DSM).
Input
Mosaic Dataset
The input mosaic dataset, which must have completed the block adjustment
process and have a stereo model.
To block adjust the mosaic dataset, use the Apply Block Adjustment tool.
To build a stereo model on the mosaic dataset, use the Build Stereo Model tool.
Matching
Method
The method used to generate 3D points.
· ETM—A feature-based stereo matching in which the Harris operator is used
in detecting feature points. Since less feature points are extracted, this
method is fast and can be used for data with less terrain variations and
detail.
· SGM—Semi-Global Matching (SGM) produces points that are denser and have
more detailed terrain information. It can be used for images of urban areas.
This is more computational intensive than ETM.1
· MVM—Multi-view image matching (MVM) is based on the SGM matching method
followed by a fusion step in which the redundant depth estimations across a
single stereo model are merged. It produces dense 3D points and is
computationally efficient.2

Output LAS
Folder
The folder used to store the output LAS files.
If this tool is run multiple times with the same input parameters, the
output may be slightly different due to random sampling.
Output LAS
Base Name
A string used as a prefix to formulate the output LAS file names. For
example, if name is used as the base, the output files will be named name1.las,
name2.las, and so on.
Maximum
Object Size (in meter) (optional)
A search radius within which surface objects, such as buildings or trees,
will be identified. It is the linear size in map units.
DSM Ground
Spacing (in meter) (optional)
The ground spacing, in meters, at which the 3D points are generated.
The default is five times the source image pixel size.
Number of
Image Pairs (optional)
The number of pairs used to generate 3D points. The default value is a
minimum of 2 image pairs.
Sometimes a location may be covered with many image pairs. In this case,
the tool will order the pairs based on the various threshold parameters
specified in this tool. The pairs with the highest scores will be used to
generate the points.
Overlap
Area Threshold (optional)
Specify a minimum overlap threshold area that is acceptable, which is a
percentage of overlap between a pair of images. Image pairs with overlap areas
smaller than this threshold will receive a score of 0 for this criteria and
will descend in the ordered list. The range of values for the threshold is from
0 to 1. The default threshold value is 0.6, which is equal to 60 percent.
Adjustment
Quality Threshold (optional)
Specify the minimum adjustment quality that is acceptable. The threshold
value will be compared to the adjustment quality value that is stored in the
stereo model. Image pairs with an adjustment quality less than the specified
threshold will receive a score of 0 for this criteria and will descend in the
ordered list. The range of values for the threshold is from 0 to 1. The default
value is 0.2, which is equal to 20 percent.
GSD
Difference Threshold (optional)
Specify the maximum allowable threshold for the ground sample distance
(GSD) between two images in a pair. The resolution ratio between the two images
will be compared to the threshold value. Image pairs with a ground sample ratio
greater than this threshold will receive a score of 0 for this criteria and
will descend in the ordered list. The default threshold ratio is 2.
Omega/Phi
Difference Threshold (optional)
Specify the maximum threshold for the Omega\Phi difference between the two
image pairs. The Omega values and Phi values for the image pairs are compared.
Image pairs with an Omega or a Phi difference greater than this threshold will
receive a score of 0 for this criteria and will descend in the ordered list.
The default threshold difference for each comparison is 8.

the adjustment quality value that is stored in the stereo model. Image pairs
with an adjustment quality less than the specified threshold will receive a
score of 0 for this criteria and will descend in the ordered list. The range of
values for the threshold is from 0 to 1. The default value is 0.2, which is
equal to 20 percent.
حدد أدنى جودة ضبط مقبولة. ستتم مقارنة قيمة
العتبة بقيمة جودة الضبط المخزنة في نموذج الاستريو. ستحصل أزواج الصور ذات جودة
الضبط الأقل من الحد المحدد على درجة 0 لهذه المعايير وستنخفض في القائمة المرتبة.
يتراوح نطاق قيم الحد من 0 إلى 1. القيمة الافتراضية هي 0.2 ، والتي تساوي 20
بالمائة.
GSD
Difference Threshold (optional)
Specify the maximum allowable threshold for the ground sample distance
(GSD) between two images in a pair. The resolution ratio between the two images
will be compared to the threshold value. Image pairs with a ground sample ratio
greater than this threshold will receive a score of 0 for this criteria and
will descend in the ordered list. The default threshold ratio is 2.
Omega/Phi
Difference Threshold (optional)
Specify the maximum threshold for the Omega\Phi difference between the two
image pairs. The Omega values and Phi values for the image pairs are compared.
Image pairs with an Omega or a Phi difference greater than this threshold will
receive a score of 0 for this criteria and will descend in the ordered list.
The default threshold difference for each comparison is 8.

GSD Difference Threshold (optional) عتبة الفرق (اختياري)
Specify the maximum
allowable threshold for the ground sample distance (GSD) between two images in
a pair. The resolution ratio between the two images will be compared to the
threshold value. Image pairs with a ground sample ratio greater than this threshold
will receive a score of 0 for this criteria and will descend in the ordered
list. The default threshold ratio is 2.
Omega/Phi
Difference Threshold (optional)
Specify the maximum threshold for the Omega\Phi difference between the two
image pairs. The Omega values and Phi values for the image pairs are compared.
Image pairs with an Omega or a Phi difference greater than this threshold will
receive a score of 0 for this criteria and will descend in the ordered list.
The default threshold difference for each comparison is 8.

حدد الحد الأقصى المسموح به لمسافة العينة الأرضية (GSD) بين صورتين في
زوج. ستتم مقارنة نسبة الدقة بين الصورتين بقيمة العتبة. ستحصل أزواج الصور التي
تحتوي على نسبة عينة أرضية أكبر من هذا الحد على درجة 0 لهذه المعايير وستنخفض في
القائمة المرتبة. نسبة العتبة الافتراضية هي 2.
11.
Omega/Phi Difference Threshold (optional) عتبة فرق أوميغا / فاي (اختياري)
Specify the maximum
threshold for the Omega\Phi difference between the two image pairs. The Omega
values and Phi values for the image pairs are compared. Image pairs with an
Omega or a Phi difference greater than this threshold will receive a score of 0
for this criteria and will descend in the ordered list. The default threshold
difference for each comparison is 8.
حدد الحد الأقصى للفرق في Omega \ Phi بين زوجي الصور. تتم مقارنة قيم أوميغا وقيم فاي لأزواج الصور.
أزواج الصور التي تحتوي على أوميغا أو فارق Phi أكبر
من هذا الحد ستحصل على درجة 0 لهذه المعايير وستنخفض في القائمة المرتبة. فرق الحد
الافتراضي لكل مقارنة هو 8.
