Capturing raw data from depth-sensing cameras
Now that you have installed the prerequisite libraries and drivers, we will demonstrate how to capture raw data from your depth-sensing camera.
How to do it...
To capture sensor data directly in a binary format, implement the following function:
void writeDepthBuffer(openni::VideoFrameRef depthFrame){ static int depth_buffer_counter=0; char file_name [512]; sprintf(file_name, "%s%d.bin", "depth_frame", depth_buffer_counter); openni::DepthPixel *depthPixels = new openni::DepthPixel[depthFrame.getHeight()*depthFrame.getWidth()]; memcpy(depthPixels, depthFrame.getData(), depthFrame.getHeight()*depthFrame.getWidth()*sizeof(uint16_t)); std::fstream myFile (file_name, std::ios::out |std::ios::binary); myFile.write ...Become an O’Reilly member and get unlimited access to this title plus top books and audiobooks from O’Reilly and nearly 200 top publishers, thousands of courses curated by job role, 150+ live events each month,
