将 ARM 的 Orbbec Embedded S 摄像头与 OpenNI 结合使用答案

【问题标题】：Using Orbbec Embedded S camera from ARM with OpenNI将 ARM 的 Orbbec Embedded S 摄像头与 OpenNI 结合使用
【发布时间】：2019-11-25 01:09:23
【问题描述】：

我有一个已连接嵌入式 S 相机的 ARM SoC。我可以看到相机已连接：

$ lsusb
Bus 001 Device 006: ID 2bc5:050b
Bus 001 Device 007: ID 2bc5:060b

我从https://orbbec3d.com/develop/ 下载了OpenNI_2.3.0.63.zip，然后将 OpenNI-Linux-Arm64-2.3.0.63 目录复制到我的设备并运行 install.sh。现在，当我插入相机时，我得到：

[ 5887.390778] hub 1-1:1.0: 2 ports detected
[ 5887.879656] usb 1-1.1: New USB device found, idVendor=2bc5, idProduct=050b
[ 5887.886538] usb 1-1.1: New USB device strings: Mfr=2, Product=1, SerialNumber=3
[ 5887.894193] usb 1-1.1: Product: USB 2.0 Camera
[ 5887.898757] usb 1-1.1: Manufacturer: Sonix Technology Co., Ltd.
[ 5887.904814] usb 1-1.1: SerialNumber: SN0001
[ 5888.232284] usb 1-1.2: New USB device found, idVendor=2bc5, idProduct=060b
[ 5888.239161] usb 1-1.2: New USB device strings: Mfr=1, Product=2, SerialNumber=0
[ 5888.246856] usb 1-1.2: Product: ORBBEC Depth Sensor
[ 5888.251853] usb 1-1.2: Manufacturer: Orbbec(R)

我交叉编译了一个简单的应用程序：

int main(int argc, char** argv)
{
    const char* deviceURI = openni::ANY_DEVICE;
    Status result = STATUS_OK;
    result = OpenNI::initialize();
    cout << "OpenNI::initialize() = " << result << endl;
    openni::Array<openni::DeviceInfo> deviceList;
    openni::OpenNI::enumerateDevices(&deviceList);
    cout << "OpenNI::enumerateDevices() = " << deviceList.getSize() << endl;
    for (int i = 0; i < deviceList.getSize(); ++i)
    {
        cout << "Device " << deviceList[i].getUri() << " already connected" << endl;
    }

当我第一次运行它时，我得到了：

error while loading shared libraries: libOpenNI2.so: cannot open shared object file: No such file or director

所以我将 libOpenNI2.so 复制到 /usr/lib。现在当我运行它时，我得到：

OpenNI::initialize() = 1
OpenNI::enumerateDevices() = 0

为什么没有看到摄像头？我还需要做些什么才能让它工作吗？

【解决方案1】：

我使用以下方式打开了日志记录：

OpenNI::setLogMinSeverity(0);
OpenNI::setLogConsoleOutput(true);

看到了：

所以我将文件从 OpenNI-Linux-Arm64-2.3.0.63/Redist/OpenNI2/Drivers/ 复制到 /usr/lib/OpenNI2/Drivers/。自述文件还说：

*for using with Astra Embedded S/Stereo S, please change the resolution in 'orbbec.ini' to 'Resolution=17' for Depth and IR streams

所以我在 /usr/lib/OpenNI2/Drivers/orbbec.ini 中编辑了这个。现在我明白了：

OpenNI::enumerateDevices() = 0

哪个更好，但仍然没有成功。然后我意识到我在复制驱动程序文件后没有重新连接相机，所以我这样做了，它成功了。
