Getting started

0) Hardware Install

Please add one usb hub with Independent power supply. Then insert the double head USB cable together on the USB hub and connect the usb hub to your PC.

1) SET VOXEL_SDK_PATH

To install vim and cmake, please run:

sudo apt-get install cmake vim

Please run # uname -a to check system platform version first.

Plateform SDK Path
Ubuntu 14.04 /third_party/voxelsdk_ubuntu_3.13
Ubuntu 16.04 /third_party/voxelsdk_ubuntu_4.13
MacOs /third_party/voxelsdk_osx

Modify .bashrc to set environment variables:

# vim ~/.bashrc

add below source code to the end of bashrc file:

export VOXEL_SDK_PATH="your_directory/third_party/voxelsdk_ubuntu_3.13"
export PATH=$VOXEL_SDK_PATH/lib:$VOXEL_SDK_PATH/bin:$PATH

PS:Please remember to replace voxelsdk_ubuntu_3.13 with your system platform.

We need to make above changes come into effect:

# source ~/.bashrc

Finally, echo the constant to verify :

# echo $VOXEL_SDK_PATH

2) SET USB Driver

(For Ubuntu only)

sudo cp ./third_party/udev/rules.d/72-DepthEyeH1CDK.rules /etc/udev/rules.d/

sudo chmod a+x /etc/udev/rules.d/72-DepthEyeH1CDK.rules

sudo udevadm control --reload

3) Make

In the root directory of SDK, run below commands one by one:

$ mkdir build

$ cd build/ 

$ cmake ..

$ make 

You can get message as below :

[100%] Built target H1AsciiSample

Plug the module and run it:

./bin/H1AsciiSample

You can see the result!
