Configuring OpenNi2 under Windows (obbrec)

Obi Zhongguang VisualStdio 2019 documentation , I wrote this a few days ago. I didn't compile it. I'll write it today.

SDK download location, download, unzip and remember the path

These are the Demo for. Let's use one

Create an empty project

Create a new CPP file

#include <stdio.h>
#include <OpenNI.h>

#include "OniSampleUtilities.h"

#define SAMPLE_READ_WAIT_TIMEOUT 2000 //2000ms

using namespace openni;

int main(int argc, char* argv[])
{
  //initialize openni sdk
  Status rc = OpenNI::initialize();
  if (rc != STATUS_OK)
  {
    printf("Initialize failed\n%s\n", OpenNI::getExtendedError());
    return 1;
  }

  Device device;

  //open device
  rc = device.open(ANY_DEVICE);
  if (rc != STATUS_OK)
  {
    printf("Couldn't open device\n%s\n", OpenNI::getExtendedError());
    return 2;
  }

  VideoStream depth;

  //create depth stream
  if (device.getSensorInfo(SENSOR_DEPTH) != NULL)
  {
    rc = depth.create(device, SENSOR_DEPTH);
    if (rc != STATUS_OK)
    {
      printf("Couldn't create depth stream\n%s\n", OpenNI::getExtendedError());
      return 3;
    }
  }

  //start depth stream
  rc = depth.start();
  if (rc != STATUS_OK)
  {
    printf("Couldn't start the depth stream\n%s\n", OpenNI::getExtendedError());
    return 4;
  }

  VideoFrameRef frame;

  while (!wasKeyboardHit())
  {
    int changedStreamDummy;
    VideoStream* pStream = &depth;

    //wait a new frame
    rc = OpenNI::waitForAnyStream(&pStream, 1, &changedStreamDummy, SAMPLE_READ_WAIT_TIMEOUT);
    if (rc != STATUS_OK)
    {
      printf("Wait failed! (timeout is %d ms)\n%s\n", SAMPLE_READ_WAIT_TIMEOUT, OpenNI::getExtendedError());
      continue;
    }

    //get depth frame
    rc = depth.readFrame(&frame);
    if (rc != STATUS_OK)
    {
      printf("Read failed!\n%s\n", OpenNI::getExtendedError());
      continue;
    }

    //check if the frame format is depth frame format
    if (frame.getVideoMode().getPixelFormat() != PIXEL_FORMAT_DEPTH_1_MM && frame.getVideoMode().getPixelFormat() != PIXEL_FORMAT_DEPTH_100_UM)
    {
      printf("Unexpected frame format\n");
      continue;
    }

    DepthPixel* pDepth = (DepthPixel*)frame.getData();

    int middleIndex = (frame.getHeight() + 1) * frame.getWidth() / 2;

    //print the depth value of the middle pixel of the frame
    printf("[%08llu] %8d\n", (long long)frame.getTimestamp(), pDepth[middleIndex]);
  }

  //stop depth stream
  depth.stop();

  //destroy depth stream
  depth.destroy();

  //close device
  device.close();

  //shutdown OpenNI
  OpenNI::shutdown();

  return 0;
}

Copy my code in

Then start configuring the library, or the location of the header.

It mainly indicates these places

Project - > Properties

SDK content

What does the downloaded SDK look like

Configure this at the beginning

Add two directories

C:\orbbec\Windows_V2.3.0.66\windows\Samples\samples\Common
C:\orbbec\Windows_V2.3.0.66\windows\SDK\x64\Include

common is the header file of this

This adds the library

Link library - > General

Add the path of DLL file

Then the input

Write this

Remember to click the app!!! Otherwise, you can't save your settings

If you do not save, an error will be reported

If you configure it correctly, there are no wavy lines in these places

F12

It can be opened

Look at our device manager

We can compile it now. It should not report errors and pass the compilation

If it runs, you need to add something.

C:\orbbec\Windows_V2.3.0.66\windows\Samples\bin_x64

Open the bin location of an SDK

These are

Then you open the current project location

Copy it

Operation results

It seems that you want to copy the past and compile... I think I'm in the wrong order...

Make a breakpoint

Look at the content

result

Let's take a look at the meaning of the program. The above is the location of the demo

Let's first look at the introduction of three header files

Then there is a macro with a time of 2000ms

Here is a namespace, namespace

This is introduced in the header file of OponNI2, where I refer to the namespace

The initialization method is used for the device at the beginning, and then the return value is determined

To determine if the equipment is ready

This is the correct and wrong definition position

This initialization method

These are possible error values

After the above is completed, start creating a device object

This is the location

Turn on the device, if ok

Then a video streaming device is created. If the device information above is not empty. Then execute the following statement to create a device and add two parameters, one is the device at that time and the color information.
