How to generate a 3D point cloud from depth image and color image acquired from Matlab

不羁的心 提交于 2019-12-21 17:57:36
问题 I have 2 set data acquired from kinect 1- depth image with size 480*640 (uint16) from a scene 2- color image with same size (480*640*3 single) from same scene The question is how can I merge these data together to generate a colored 3D point clouds with PLY format in Matlab. I need to say that unfortunately I don't have an access to kinect anymore and i should use only these data. 回答1: I've never tried to do that in matlab, but i think that this is what you are looking for: http://es

Kinect 3D gesture recognition based on skeleton movements - What libraries exist?

蓝咒 提交于 2019-12-21 17:11:40
问题 What gesture recognition libraries (if any) exist for the Kinect? Right now I'm using OpenNI to record skeleton movements but am not sure how to go from that to triggering discrete actions. My problem might be as simple as pose detection but it could also be as complicated as time based movements (ie. detect when they are moving their hand in a circle) depending on how difficult that is. The examples that I've seen for pose detection have been very ad-hoc - is this because a generic algorithm

Get Depth at Color position, Kinect SDK

强颜欢笑 提交于 2019-12-21 06:20:46
问题 I am looking for way to (as quick as possible) get the corresponding depth to a color pixel from the Kinect camera. I have found the MapDepthFrameToColorFrame function. But that only gives me the color at a certain depth position, I want the opposite. The reason I want this is that I will be able to click on a position at the RGB image and get the position to that pixel. Is there a way to do this faster than looping through all results from MapDepthFrameToColorFrame? 回答1: The problem here is

Convert kinect RGB and depth values to XYZ coordinates

只愿长相守 提交于 2019-12-21 05:23:10
问题 I'm looking for an easy way to Convert kinect RGB and depth values to XYZ coordinates using MATLAB. My goal is a function with an input of: RGB and depth values of each point taking by Kinect camera, and output of: x,y and z values of each point. [RGB, depth] = RGB_D2XYZ(XYZ) Thanks, Ben 回答1: You can have a look to this great article. They have a function call DepthToCloud.m. You just need to be sure to pass Image center and top-left corner. They are using Kinect too, so you don't really need

How to align RGB and Depth image from Kinect in Matlab

问题 I am trying to align RGB and Depth image from Kinect using Matlab. I am trying to do it using the algorithm from this page. Here is the code I have written so far depth = imread('depth_00500.png'); color = imread('rgb_00500.png'); rotationMat=[9.9984628826577793e-01 1.2635359098409581e-03 -1.7487233004436643e-02; -1.4779096108364480e-03 9.9992385683542895e-01 -1.2251380107679535e-02; 1.7470421412464927e-02 1.2275341476520762e-02 9.9977202419716948e-01 ]; translationMat=[1.9985242312092553e-02

Open-source tool for gender-recognition using voice [closed]

三世轮回 提交于 2019-12-21 02:50:52
问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 4 years ago . Good evening, I'm working on a project with Kinect and I need to perform a gender-recognition using the voice information caught by the microphone of the sensor. The recognition could also be text-based , i.e. the sentence said by the user could always be the same. I "just" need the binary answer male/female. I

How to align kinect's depth image with color image

折月煮酒 提交于 2019-12-20 10:04:27
问题 The image produced by the color and depth sensor on the Kinect are slightly out of alignment. How can I transform them to make them line up? 回答1: The key to this is the call to 'Runtime.NuiCamera.GetColorPixelCoordinatesFromDepthPixel' Here is an extension method for the Runtime class. It returns a WriteableBitmap object. This WriteableBitmap is automatically updated as new frames come in. So the usage of it is really simple: kinect = new Runtime(); kinect.Initialize(RuntimeOptions.UseColor |

Matching Kinect Audio with Video

若如初见. 提交于 2019-12-20 09:39:35
问题 I have a project dealing with video conferencing using the Kinect (or, more likely, four of them). Right now, my company uses these stupidly expensive cameras for our VTC rooms. The hope is, using a couple Kinects linked together, we can reduce the costs. The plan is to have four/five of them covering a 180 degree arc so the Kinects can see the entire room/table (still a lot cheaper than our current cameras!). The applications would choose a video stream coming from a Kinect based on who at

Microsoft Kinect SDK depth data to real world coordinates

假装没事ソ 提交于 2019-12-20 09:37:00
问题 I'm using the Microsoft Kinect SDK to get the depth and color information from a Kinect and then convert that information into a point cloud. I need the depth information to be in real world coordinates with the centre of the camera as the origin. I've seen a number of conversion functions but these are apparently for OpenNI and non-Microsoft drivers. I've read that the depth information coming from the Kinect is already in millimetres, and is contained in the 11bits... or something. How do I
