&lt;td&gt;&lt;/td&gt;
&lt;/tr&gt;
&lt;/tbody&gt;
&lt;/table&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;A quick guide to the Calibration of any camera using ContextCapture&lt;/p&gt;
&lt;h1&gt;Steps to Accomplish&lt;/h1&gt;
&lt;h3&gt;Step&amp;nbsp;1.&amp;nbsp; &amp;nbsp;Camera Setup&lt;/h3&gt;
&lt;ol&gt;
&lt;li&gt;
&lt;p&gt;Remove optical stabilization.&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;Disable photo auto-rotation&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;If you are unfamiliar with the camera use &amp;lt;&amp;lt;Automatic&amp;gt;&amp;gt; mode&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;Fix the focal length&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;Fix image dimensions&lt;/p&gt;
&lt;/li&gt;
&lt;/ol&gt;
&lt;p&gt;Changing the camera focal length (zoom+/-) and / or the image dimensions will result in a different calibration.&lt;/p&gt;
&lt;h3&gt;Step&amp;nbsp;2. &amp;nbsp;&amp;nbsp;Photo acquisition&lt;/h3&gt;
&lt;ol&gt;
&lt;li&gt;
&lt;p&gt;&lt;span style="font-size:inherit;"&gt;Select a highly textured and geometrically complex scene&lt;/span&gt;&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;&lt;span style="font-family:arial,helvetica,sans-serif;font-size:inherit;"&gt;Acquire photos at 360 deg around the scene&lt;/span&gt;&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;&lt;span style="font-family:arial,helvetica,sans-serif;font-size:inherit;"&gt;Shoot photos holding the camera in different positions (horizontal / vertical). &lt;strong&gt;NB. this only applies if auto-rotation mode is disabled&amp;nbsp;&lt;/strong&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style="font-family:arial,helvetica,sans-serif;font-size:inherit;"&gt;&lt;strong&gt;&lt;a href="/cfs-file/__key/communityserver-wikis-components-files/00-00-00-02-18/Photo-Aquisition.png"&gt;&lt;img alt=" " src="/resized-image/__size/940x0/__key/communityserver-wikis-components-files/00-00-00-02-18/Photo-Aquisition.png" /&gt;&lt;/a&gt;&lt;br /&gt;&lt;/strong&gt;&lt;/span&gt;&lt;/p&gt;
&lt;/li&gt;
&lt;/ol&gt;
&lt;h3&gt;Step&amp;nbsp;3. &amp;nbsp;&amp;nbsp;Process your dataset in ContextCapture&lt;/h3&gt;
&lt;ol&gt;
&lt;li&gt;Create a new project and import your photos&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;In the Photogroup tab, select the type of camera being used: perspective / fish-eye&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;Submit and aerotriangulation. In the aerotriangulation definition keep the settings set at default&lt;/p&gt;
&lt;/li&gt;
&lt;/ol&gt;
&lt;p&gt;&lt;img alt=" " src="/resized-image/__size/640x480/__key/communityserver-wikis-components-files/00-00-00-02-18/pastedimage1652783994370v1.png" /&gt;&lt;/p&gt;
&lt;p&gt;&lt;a href="/cfs-file/__key/communityserver-wikis-components-files/00-00-00-02-18/Aerotriangulation.png"&gt;&lt;/a&gt;&lt;/p&gt;
&lt;h3&gt;Step&amp;nbsp;4.&amp;nbsp; &amp;nbsp;Store your camera calibration in the user database&lt;/h3&gt;
&lt;p&gt;&lt;a href="/cfs-file/__key/communityserver-wikis-components-files/00-00-00-02-18/Add-Calibration-to-DB.png"&gt;&lt;img alt=" " height="352" src="/resized-image/__size/940x0/__key/communityserver-wikis-components-files/00-00-00-02-18/Add-Calibration-to-DB.png" width="744" /&gt;&lt;/a&gt;&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;ol&gt;
&lt;li&gt;
&lt;p&gt;Go to the Photo tab and right click on the photogroup. Click &amp;lt;&amp;lt; add camera to database &amp;gt;&amp;gt;&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;When processing another project using the same camera, the latest calibration will be used by default. If not you can still browse to it from the camera database by selecting &amp;lt;&amp;lt; get camera model from the database &amp;gt;&amp;gt;&lt;/p&gt;
&lt;/li&gt;
&lt;/ol&gt;
&lt;h3&gt;Step&amp;nbsp;5.&amp;nbsp; &amp;nbsp;Prevent the software from adjusting the parameters&lt;/h3&gt;
&lt;ol&gt;
&lt;li&gt;
&lt;p&gt;In specific cases, you may want to prevent the software from adjusting the camera parameters, i.e. If a calibration already exists or has already&amp;nbsp;been imported from the database.&amp;nbsp;&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;In the aerotriangulation definition settings, under&amp;nbsp;Optical parameters select the option &amp;quot;Lock all parameters&amp;quot;.&lt;/p&gt;
&lt;/li&gt;
&lt;/ol&gt;
&lt;p&gt;&lt;a href="/cfs-file/__key/communityserver-wikis-components-files/00-00-00-02-18/Prevent-software-from-changing-perameters.png"&gt;&lt;/a&gt;&lt;img alt=" " src="/resized-image/__size/640x480/__key/communityserver-wikis-components-files/00-00-00-02-18/pastedimage1652784147472v2.png" /&gt;&lt;/p&gt;

&lt;p&gt;&lt;span style="font-size:inherit;"&gt;Select a highly textured and geometrically complex scene&lt;/span&gt;&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;&lt;span style="font-family:arial,helvetica,sans-serif;font-size:inherit;"&gt;Acquire photos at 360 deg around the scene&lt;/span&gt;&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;&lt;span style="font-family:arial,helvetica,sans-serif;font-size:inherit;"&gt;Shoot photos holding the camera in different positions (horizontal / vertical). &lt;strong&gt;NB. this only applies if auto-rotation mode is disabled&amp;nbsp;&lt;/strong&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style="font-family:arial,helvetica,sans-serif;font-size:inherit;"&gt;&lt;strong&gt;&lt;a href="/cfs-file/__key/communityserver-wikis-components-files/00-00-00-02-18/Photo-Aquisition.png"&gt;&lt;img alt=" " src="/resized-image/__size/940x0/__key/communityserver-wikis-components-files/00-00-00-02-18/Photo-Aquisition.png" /&gt;&lt;/a&gt;&lt;br /&gt;&lt;/strong&gt;&lt;/span&gt;&lt;/p&gt;
&lt;/li&gt;
&lt;/ol&gt;
&lt;h3&gt;Step&amp;nbsp;3. &amp;nbsp;&amp;nbsp;Process your dataset in ContextCapture&lt;/h3&gt;
&lt;ol&gt;
&lt;li&gt;Create a new project and import your photos&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;In the Photogroup tab, select the type of camera being used: perspective / fish-eye&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;Submit and aerotriangulation. In the aerotriangulation definition settings set &amp;lt;&amp;lt; optical properties estimation mode &amp;gt;&amp;gt; to &amp;lt;&amp;lt; multipass &amp;gt;&amp;gt;&lt;/p&gt;
&lt;/li&gt;
&lt;/ol&gt;
&lt;p&gt;&lt;a href="/cfs-file/__key/communityserver-wikis-components-files/00-00-00-02-18/Aerotriangulation.png"&gt;&lt;img width="759" height="439" alt=" " src="/resized-image/__size/940x0/__key/communityserver-wikis-components-files/00-00-00-02-18/Aerotriangulation.png" /&gt;&lt;/a&gt;&lt;/p&gt;
&lt;h3&gt;Step&amp;nbsp;4.&amp;nbsp; &amp;nbsp;Store your camera calibration in the user database&lt;/h3&gt;
&lt;p&gt;&lt;a href="/cfs-file/__key/communityserver-wikis-components-files/00-00-00-02-18/Add-Calibration-to-DB.png"&gt;&lt;img width="744" height="352" alt=" " src="/resized-image/__size/940x0/__key/communityserver-wikis-components-files/00-00-00-02-18/Add-Calibration-to-DB.png" /&gt;&lt;/a&gt;&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;ol&gt;
&lt;li&gt;
&lt;p&gt;Go to the Photo tab and right click on the photogroup. Click &amp;lt;&amp;lt; add camera to database &amp;gt;&amp;gt;&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;When processing another project using the same camera, the latest calibration will be used by default. If not you can still browse to it from the camera database by selecting &amp;lt;&amp;lt; get camera model from the database &amp;gt;&amp;gt;&lt;/p&gt;
&lt;/li&gt;
&lt;/ol&gt;
&lt;h3&gt;Step&amp;nbsp;5.&amp;nbsp; &amp;nbsp;Prevent the software from adjusting the parameters&lt;/h3&gt;
&lt;ol&gt;
&lt;li&gt;
&lt;p&gt;In specific cases, you may want to prevent the software from adjusting the camera parameters, i.e. If a calibration already exists or has already&amp;nbsp;been imported from the database.&amp;nbsp;&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;In the aerotriangulation definition settings, set the focal length, principal point and radial distortion to &amp;lt;&amp;lt; keep &amp;gt;&amp;gt;.&lt;/p&gt;
&lt;/li&gt;
&lt;/ol&gt;

&lt;/tbody&gt;
&lt;/table&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;A quick guide to the Calibration of any camera using ContextCapture&lt;/p&gt;
&lt;h1&gt;Steps to Accomplish&lt;/h1&gt;
&lt;h3&gt;Step&amp;nbsp;1.&amp;nbsp; &amp;nbsp;Camera Setup&lt;/h3&gt;
&lt;ol&gt;
&lt;li&gt;
&lt;p&gt;Remove optical stabilization.&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;Disable photo auto-rotation&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;If you are unfamiliar with the camera use &amp;lt;&amp;lt;Automatic&amp;gt;&amp;gt; mode&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;Fix the focal length&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;Fix image dimensions&lt;/p&gt;
&lt;/li&gt;
&lt;/ol&gt;
&lt;p&gt;Changing the camera focal length (zoom+/-) and / or the image dimensions will result in a different calibration.&lt;/p&gt;
&lt;h3&gt;Step&amp;nbsp;2. &amp;nbsp;&amp;nbsp;Photo acquisition&lt;/h3&gt;
&lt;ol&gt;
&lt;li&gt;
&lt;p&gt;&lt;span style="font-size:inherit;"&gt;Select a highly textured and geometrically complex scene&lt;/span&gt;&lt;/p&gt;

&lt;li&gt;
&lt;p&gt;&lt;span style="font-family:arial,helvetica,sans-serif;font-size:inherit;"&gt;Acquire photos at 360 deg around the scene&lt;/span&gt;&lt;/p&gt;
&lt;/li&gt;

&lt;p&gt;&lt;span style="font-family:arial,helvetica,sans-serif;font-size:inherit;"&gt;Shoot photos holding the camera in different positions (horizontal / vertical). &lt;strong&gt;NB. this only applies if auto-rotation mode is disabled&amp;nbsp;&lt;/strong&gt;&lt;/span&gt;&lt;/p&gt;

&lt;td&gt;N\A&lt;/td&gt;
&lt;td&gt;&lt;/td&gt;
&lt;/tr&gt;
&lt;/tbody&gt;
&lt;/table&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;A quick guide to the Calibration of any camera using ContextCapture&lt;/p&gt;
&lt;h1&gt;Steps to Accomplish&lt;/h1&gt;
&lt;h3&gt;Step&amp;nbsp;1. Camera Setup&lt;/h3&gt;
&lt;ol&gt;
&lt;li&gt;
&lt;p&gt;Remove optical stabilization.&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;Disable photo auto-rotation&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;If you are unfamiliar with the camera use &amp;lt;&amp;lt;Automatic&amp;gt;&amp;gt; mode&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;Fix the focal length&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;Fix image dimensions&lt;/p&gt;
&lt;/li&gt;
&lt;/ol&gt;
&lt;h3&gt;Step&amp;nbsp;2. Photo acquisition&lt;/h3&gt;
&lt;ol&gt;
&lt;li&gt;
&lt;p&gt;&lt;span style="font-size:inherit;"&gt;Select a highly textured and geometrically complex scene&lt;/span&gt;&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;&lt;span style="font-family:arial,helvetica,sans-serif;font-size:inherit;"&gt;Acquire photos at 360 deg around the scene&lt;/span&gt;&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;&lt;span style="font-family:arial,helvetica,sans-serif;font-size:inherit;"&gt;Shoot photos holding the camera in different positions (horizontal / vertical). NB. this only applies if auto-rotation mode is disabled&amp;nbsp;&lt;/span&gt;&lt;/p&gt;
&lt;/li&gt;
&lt;/ol&gt;
&lt;h3&gt;Step&amp;nbsp;3. Process your dataset in ContextCapture&lt;/h3&gt;
&lt;ol&gt;
&lt;li&gt;Create a new project and import your photos&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;In the Photogroup tab, select the type of camera being used: perspective / fish-eye&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;Submit and aerotriangulation. In the aerotriangulation definition settings set &amp;lt;&amp;lt; optical properties estimation mode &amp;gt;&amp;gt; to &amp;lt;&amp;lt; multipass &amp;gt;&amp;gt;&lt;/p&gt;
&lt;/li&gt;
&lt;/ol&gt;
&lt;h3&gt;Step&amp;nbsp;4. Store your camera calibration in the user database&lt;/h3&gt;
&lt;ol&gt;
&lt;li&gt;
&lt;p&gt;Go to the Photo tab and right click on the photogroup. Click &amp;lt;&amp;lt; add camera to database &amp;gt;&amp;gt;&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;When processing another project using the same camera, the latest calibration will be used by default. If not you can still browse to it from the camera database by selecting &amp;lt;&amp;lt; get camera model from the database &amp;gt;&amp;gt;&lt;/p&gt;
&lt;/li&gt;
&lt;/ol&gt;
&lt;h3&gt;Step&amp;nbsp;5. Prevent the software from adjusting the parameters&lt;/h3&gt;
&lt;ol&gt;
&lt;li&gt;
&lt;p&gt;In specific cases, you may want to prevent the software from adjusting the camera parameters, i.e. If a calibration already exists or has already&amp;nbsp;been imported from the database.&amp;nbsp;&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;In the aerotriangulation definition settings, set the focal length, principal point and radial distortion to &amp;lt;&amp;lt; keep &amp;gt;&amp;gt;.&lt;/p&gt;
&lt;/li&gt;
&lt;/ol&gt;
