openni

I am trying to implement a finger detection, which link is given here . Am I am going through the code in MSVC2010, it gives me error as shown in Figure as shown below. Could someone tell me why the following codes gives me error? Is this related to these following questions; 1 , 2 , 3 ? Is there a possible workaround? I already included: #include <cstdint> #include <stdint.h> I also tried: unsigned short depth = (unsigned short) (v[2] * 1000.0f); // hand depth unsigned short near = (unsigned short) (depth - 100); // near clipping plane unsigned short far = (unsigned short) (depth + 100); //

I'm trying to build a Node.js addon that makes use of OpenNI. I haven't used Node-gyp before so I'm trying to set up the binding.gyp file so that it includes the OpenNI library as part of the build. The code I'm actually compiling is just the Hello World example . The binding.gyp file I'm using is based on the one from NUIMotion on Github, which is doing something similar. Here's mine: { "targets": [ { "target_name": "onijs", "sources": [ "src/main.cpp" ], "include_dirs": [ "./src/Include" ], "libraries": [ "-lOpenNI2", "-Wl,-rpath ./" ] } ] } Here's what I've done (working in OSX): Created a

I'm using OpenNI and OpenCV (but without the latest code with openni support). If I just send the depth channel to the screen - it will look dark and difficult to understand something. So I want to show a depth channel for the user in a color but cannot find how to do that without losing of accuracy. Now I do it like that: xn::DepthMetaData xDepthMap; depthGen.GetMetaData(xDepthMap); XnDepthPixel* depthData = const_cast<XnDepthPixel*>(xDepthMap.Data()); cv::Mat depth(frame_height, frame_width, CV_16U, reinterpret_cast<void*>(depthData)); cv::Mat depthMat8UC1; depth.convertTo(depthMat8UC1, CV

How would one extract the components of the intrinsic and extrinsic calibration parameters from OpenNI for a device such as the PrimeSense? After some searching I only seem to find how to do it through ROS, but it is not clear how it would be done with just OpenNI. 来源： https://stackoverflow.com/questions/41110791/openni-intrinsic-and-extrinsic-calibration

I'm playing with the built in OpenNI access within OpenCV 2.4.0 and I'm trying to measure the distance between two points in the depth map. I've tried this so far: #include "opencv2/core/core.hpp" #include "opencv2/highgui/highgui.hpp" #include "opencv2/imgproc/imgproc.hpp" #include <iostream> using namespace cv; using namespace std; Point startPt(0,0); Point endPt(0,0); void onMouse( int event, int x, int y, int flags, void* ) { if( event == CV_EVENT_LBUTTONUP) startPt = Point(x,y); if( event == CV_EVENT_RBUTTONUP) endPt = Point(x,y); } int main( int argc, char* argv[] ){ VideoCapture capture

Emgu CV currently allows the use of the Kinect with the OpenNI drivers . I've also seen that there exists an mssdk-openni bridge application to allow the Kinects running on the official Microsoft SDK to emulate OpenNI driven Kinects. Has anyone been successful in getting a Kinect running on the Microsoft SDK to work with Emgu CV, either with the mssdk-openni bridge or directly? Are there any tips on getting it running smoothly, or pitfalls to avoid? Yeah. I've simply installed the SDK and could capture and extract bitmaps of the video stream. The MSSDK for Kinect works just fine and easy. You
