Z+F Laser Control Software
The native format for data
capture with the LVC0702 is Z+F's zfs format. Download and run the following executable to
install Z+F's Laser Control Software which can open and view these files:
Z+FSetup.exe
Data Files in Z+F Format and ASCII 3D Format
The first sample data
set is of a single frame of a high resolution scan of a garage, in both the zfs
format and as an Ascii 3D data file which is compatible with many 3D viewing
programs. The first three columns of the ASCII data file are the X, Y and
Z coordinates of each point, and the fourth is the reflectivity. This data
set was captured in 0.8 seconds:
garage.zfs, garage.asc.
If you do not have a
suitable 3D viewer, a video of a fly through of the garage data set can be found
on our lidar product page.
The second sample data set is again of a single high resolution
frame captured in 0.8 seconds, this time of a house under construction:
house.zfs, house.asc.
A video of a fly through of the house data set can be found
on our lidar product page.
The third sample
data set is of a sequence of frames captured from a moving truck. Both zfs
and ASCII 3D data sets are included in the following zip file:
driving.zip.
A video of a
flythrough of a point cloud containing this data can also be found on our lidar
product page.
Accuracy Check of the LVC0702
The following are a series of frames taken with the LVC0702 camera in high
resolution mode (45ºx90º, 288 x 960 pixels). In the frames is a
whiteboard target positioned at distances of 10, 20, 30, 40 and 50m from the
front of the camera, using a hand held tape for distance measurement.
When these frames are displayed in the Z+F viewer it can be seen by putting
the cursor on the target that the measured range to the target is in good
agreement with the known value, keeping in mind that there is 35cm of
internal path length inside the camera before the front of the camera is
reached, and that the accuracy that can be achieved with a simple tape measure
is limited:
10m_1_frame1.zfs, 20m_1_frame1.zfs,
30m_1_frame1.zfs, 40m_1_frame1.zfs,
50m_1_frame1.zfs
Camera Simulator and Real Time Viewer
To install our Camera Simulator and Real Time Viewer, download the following
zip file, and unzip its contents to a new directory:
RTViewer+SimZF.zip
NOTE: Depending on the
configuration of your computer, you may also need to download and run some support files
from Microsoft before you can run the Simulator or Real Time Viewer. These
support files can be found in the next section of this webpage.
To run the Camera Simulator, run the batch file "intruck1 serve.bat" which will
be located in the directory you created when you downloaded and unzipped the
file above. This will start a program which broadcasts data packets over
UDP in just the same way as our camera. The data stream broadcast is the same as
in the intruck1.zfs file above.
To view the data stream being broadcast by the simulator, run the application
RTViewer.exe which is also located in the directory you created when you
downloaded and unzipped the file above. The viewer has a number of on
screen options to change the way the data is displayed. Note that many of
these options do not take effect until you click the Configure button. If the
application seems sluggish, try increasing the screen update rate to
200ms. This will hide the continuous updating of the image that occurs as
new lines of data come in, but allows much better performance on older
computers.
Microsoft Support Files
If you do not have Microsoft Visual C++ installed on your computer, you will
need to download and run the following redistributable file from Microsoft
before running either the Camera Simulator or Real Time Viewer.
vcredist_x86.exe
If you do not have Microsoft .Net installed on your computer, you will need
to download and run the following redistributable file from Microsoft before
running the Real Time Viewer.
dotnetfx.exe
Sample Interfacing Code
The following annotated C++ code for the RTViewer application illustrates how to implement an interface
to the UDP data stream from our camera, and display a 2 dimensional real time
image of the received data. This code was developed in Microsoft C++ but
should be readily adaptable to other platforms:
