To mount NXTCam v2 on your contraption we suggest that you use two dark gray
‘Technic Axle 3 with Stud’ as shown.
Insert axles from the front (lens side) of the NXTCam and secure with a bushing on
the back or mount it on your contraption directly.
Alternately, you may use blue ‘Technic Axle Pin with Friction’, as shown.
While disassembling contraption, leave the axles and/or pins on NXTCam.
LED on NXTCam
The LED on NXTCam blinks initially when NXTCam is booting up
(when power is connected through USB port or NXT Sensor port).
During the normal operation the LED may blink occasionally.
Configuring NXTCam Colormaps using NXTCamView
What’s a Colormap?
The objects of interest are recognized by NXTCam by matching the stored color
values with the captured image. To do that, color values of the objects of interest
need to be stored in NXTCam’s memory. These color values are known as Colormaps.
NXTCam can store up to 8 Colormaps and provide processed information of the
objects matching those Colormaps.
Default Object Colormap
The NXTCam is shipped with a default Colormap to track a light source (white light).
Download a test program or write a test program, and try tracking a light source.
Objects of interest
Below are screen dumps of NXTCamView software, showing objects of interests and
their tracking information.
