&lt;p&gt;&lt;/p&gt;
&lt;p&gt;How to Merge models from different data sources&lt;/p&gt;
&lt;h1&gt;Background&lt;/h1&gt;
&lt;p&gt;You have a requirement to do the following:&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;Mix datasets taken from different point of view&lt;/li&gt;
&lt;li&gt;Use images that cover the model from all angles&lt;/li&gt;
&lt;li&gt;Mix datasets with images that have been taken at different resolutions&lt;/li&gt;
&lt;li&gt;Merge photos taken from different sources i.e. Dataset has been acquired from images taken using a DSLRr &amp;amp; Drone Camera&lt;/li&gt;
&lt;/ul&gt;
&lt;h1&gt;Steps to Accomplish&lt;/h1&gt;
&lt;div&gt;This is the workflow you may need to follow:&lt;/div&gt;
&lt;div&gt;Mixing datasets that are too different to be matched automatically&lt;/div&gt;
&lt;p style="padding-left:30px;"&gt;1) Create two (or more if required) independent blocks: Block1 / Block 2&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p style="padding-left:30px;"&gt;2)Process AT separately on each block&lt;/p&gt;
&lt;p&gt;&lt;br /&gt;&amp;nbsp;&lt;img alt=" " src="/resized-image/__size/320x240/__key/communityserver-wikis-components-files/00-00-00-02-18/1.png" /&gt; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp;&lt;img alt=" " src="/resized-image/__size/320x240/__key/communityserver-wikis-components-files/00-00-00-02-18/2.png" /&gt; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp;&lt;br /&gt;Block1 &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; Block2&lt;/p&gt;
&lt;p style="padding-left:30px;"&gt;3) Create user tie-points in Block_1 (at least 3). These should also be visible in the photos of Block_2.&lt;/p&gt;
&lt;p&gt;&lt;img alt=" " src="/resized-image/__size/320x240/__key/communityserver-wikis-components-files/00-00-00-02-18/5125.3.PNG" /&gt;&lt;/p&gt;
&lt;p style="padding-left:30px;"&gt;4) Export the tie-point list in a txt file.&lt;/p&gt;
&lt;p&gt;&lt;img alt=" " src="/resized-image/__size/320x240/__key/communityserver-wikis-components-files/00-00-00-02-18/4.png" /&gt;&lt;/p&gt;
&lt;p style="padding-left:30px;"&gt;5) Go to Block 2 and in the Surveys, tab Import the tie-points as control points&lt;/p&gt;
&lt;p&gt;&lt;img alt=" " src="/resized-image/__size/320x240/__key/communityserver-wikis-components-files/00-00-00-02-18/6521.5.PNG" /&gt;&lt;/p&gt;
&lt;p style="padding-left:30px;"&gt;6) Perform the control points measurement in Block_2&lt;/p&gt;
&lt;p&gt;&lt;img alt=" " src="/resized-image/__size/320x240/__key/communityserver-wikis-components-files/00-00-00-02-18/6.png" /&gt;&lt;/p&gt;
&lt;p style="padding-left:30px;"&gt;7) Resubmit Block_2 AT and choose &amp;ldquo;use control points for rigid registration&amp;rdquo;&lt;/p&gt;
&lt;p&gt;&lt;img alt=" " src="/resized-image/__size/320x240/__key/communityserver-wikis-components-files/00-00-00-02-18/7.png" /&gt;&lt;/p&gt;
&lt;p style="padding-left:30px;"&gt;8) Merge both blocks&lt;/p&gt;
&lt;p&gt;&lt;img alt=" " src="/resized-image/__size/320x240/__key/communityserver-wikis-components-files/00-00-00-02-18/8.png" /&gt;&lt;/p&gt;
&lt;p style="padding-left:30px;"&gt;9) Create a reconstruction (adaptive tiling&lt;/p&gt;
&lt;p&gt;&lt;img alt=" " src="/resized-image/__size/320x240/__key/communityserver-wikis-components-files/00-00-00-02-18/9.png" /&gt;&lt;/p&gt;
&lt;p style="padding-left:30px;"&gt;10) Submit production&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;&lt;img style="border-width:0px;" alt=" " height="60" src="/cfs-file.ashx/__key/communityserver-components-sitefiles/TSG-Logo.png" width="189" /&gt;&lt;/p&gt;
&lt;table style="background-color:#dce5f0;border:0px solid #dce5f0;" border="0"&gt;
&lt;tbody&gt;
&lt;tr&gt;
&lt;td style="text-align:right;"&gt;&lt;strong&gt;&amp;nbsp;&lt;/strong&gt;&lt;/td&gt;
&lt;td style="text-align:right;"&gt;&lt;strong&gt;Original Author:&lt;/strong&gt;&lt;/td&gt;
&lt;td&gt;Felix James&lt;/td&gt;
&lt;td&gt;&lt;/td&gt;
&lt;/tr&gt;
&lt;/tbody&gt;
&lt;/table&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;

&lt;div style="font-size: 90%;"&gt;Tags: ContextCapture, Merge&lt;/div&gt;
