Step By Step Guide

prerequisites before proceeding, make sure the following steps have been completed sufficient markers have been placed in your environment the ncam marker wizard can be used to assist with this if needed you have a working calibration for the camera and lens combination that is being used a tape or laser distance measure is available so that the height of the camera can be accurately determined rigging position the camera bar on the camera so it can clearly see the markers, for ceiling markers this typically means pointing the camera bar directly upwards make sure that the camera bar is firmly mounted camera bar to main calculate the camera bar to main, this can be done by the webui or fullui ir filter apply the ir filter to the camera bar the filter is strongly recommended when using markers it allows the markers to be detected much more clearly and also minimises lens flare from ceiling mounted lights etc connect the ir emitter to either the uart or rs232 port of the connection box or server either can be used depending on which is available configure settings enable the circular feature tracking core in the preferences ensure natural feature is turned off optional limit range measure the closest and farthest possible distance between the camera bar and the markers add the minimum and maximum distance in the ui doing this will help to minimise the chances of incorrect markers being detected create an alignment and learn points using the webui, choose an alignment method that suits your usage the " rig on wheels " is the most accurate technique you need to have a tripod on wheels , pedestal, or other means of moving the camera horizontally at a fixed height follow the instructions written in the wizard and create your alignment the video below demonstrates the process locking for optimum results it is recommended to "lock" the alignment after it has been created this prevents new markers from being detected an alignment can be locked when saving it at the end of the alignment process by activating the padlock icon next to where the alignment name is entered alignments can also be locked/unlocked from the dashboard of the webui before a point cloud is locked make sure you have learnt all the markers required for your space if during the alignment wizard step, not all markers were seen, then proceed to move the camera around the environment before saving and locking the alignment important if a min/max range was configured in the "limit range" step earlier, then make sure the values are reset so that tracking will operate correctly when the camera bar is at different distances from the markers what next? i want to add more markers or learn more points? go to the webui and ensure you have the alignment loaded that you want to add to and that the system is tracking on the dashboard unlock the pointcloud by clicking on the padlock icon move the camera around to learn the new markers when finished, relock the pointcloud and save the changes by selecting "save alignment" in the actions tab you can choose to create a new name for the alignment (so you don't lose the original) or you can use the same name to write over it i want to change the zero point if you want to finetune the position of the zero point in an already existing alignment, choose the "align world" option in the actions menu then use the finetune controls to adjust the position of the zero point when finished, save the changes and choose to either create a new alignment (will keep the original) or overwrite it i want to streamline the setup and make it "set and forget" to simplify the start up process, see the next section for information on how to make the system "set and forget"
