Chapter 1 Quick Start
Overview
Thank you for using the Focus Assist Depth Sensor from Mark Roberts
Motion Control (MRMC). The Focus Assist Depth Sensor is designed for
reliable day-in, day out use in professional studio environments. Focus
Assist depth sensor camera to measure target distances in real time and
accordingly instruct the program to adjust the Focus axis. This is used
along with any MRMC rig, camera and Flair 7 software application.
Safety
•Do not use around flammable gas. All electrical equipment can
generate sparks that can ignite flammable gas.
•Keep Away From Pets and Children. The track and camera heads
have powerful motors that can pinch, so take care not to get your
hands trapped in the gears or cabling.
•Keep the equipment dry. The system has not been made
weatherproof. Do not use with wet hands.
•Keep cables tidy. Use cable ties to keep them out of harm’s way.
Hardware Requirements
•Focus assist depth sensor camera and box
•Ulti box
•Flair 7 PC, camera installed on MRMC rig and focus motor

the rig.
2. Replacing the 4 x screws with longer ones, mount the Focus assist
box by attaching it to the Ulti box.
3. On the robot arm, mount the Camera Platform and the camera if

4. Connect the cables as shown:
5. Mount the Focus Assist camera on the matte bar on the camera
platform and connect it with the USB-C port on the Focus Assist
camera using the USB-C to USB-A cable.
The position of the focus assist camera relative to the actual camera
sensor is important to get the right target distance. The measure of
offsets in the lens setups may need to be adjusted depending on
where the focus assist camera is mounted. Note that for critical
applications that require high degree of precision, it might be
beneficial to use a tape measure to accurately measure target
distances. Therefore, preferably mount focus assist camera in the
same location as your usual measure point/hook with the correct

A depth image is an image channel in which the RGB colours on the
image represent the distance between the image plane and the
corresponding object.
Using Focus Assist
Once the heat map from the Focus Assist camera is displayed in
LiveView, the Goto button in LiveView can be used to toggle
between the following two functions:
1. :When the Goto button is grey, clicking at a target in the LiveView
will display the target distance (focus position) in the Waypoint view
allowing you to store the focus value in the key frames
2. When the Goto button is green, clicking in the LiveView will pull
the focus axis to focus on that target.
If you hover the mouse pointer in the LiveView area, it should have
changed to ‘+’ rather than a pointer in the Target mode. Point at a
target and double-click. The lens motor will move to bring the target
in focus. The lens must be calibrated for Focus Assist to measure
target distances accurately.
