In the previous blog post, we used Kinect to play with an empty touch. At that time, we used the clnuiplatform driver. Recently, more and more people are turning to the openni driver. So today, we will take some time to change it, so that openni students can also use the following software to play with an empty touch. It is worth noting that after the openni driver is used, the frame rate of CCV can reach 70 +... Of course, there is water in it, but i

Openni is a simple and efficient open-source framework developed by Kinect. It is easy to use. Many universities and research institutions choose openni as a development platform instead of a powerful Kinect SDK, here we will introduce several Middleware Based on openni:

brightness (intensity) will greatly decrease with the distance, so the range of ranging is very limited. This method is very effective and cost-effective for close range (

For the second method, the advantage is that it is easy to use 2D Lidar for transformation. Compared with the first method, the scanning distance is farther under the same laser output power. Of course, due to the need to control extra degrees of freedom, the error may be large, and the scanning

Recently, due to the need to use image matching algorithms for the Kinect project, I have seen a lot of papers on the internet, and I don't know which ones are suitable for me at the moment, as a result, I think we should test these methods to find a good method that suits me. However, the problem arises. It is unrealistic to experiment with so many algorithms one by one. After care

3D Point Cloud Registration and flattening plays an important role in point cloud processing, such as the series of point cloud data that can be used to get Kinect to work together to build a larger range of 3D scenes.
This paper applies the ICP algorithm to the registration between point clouds, which can be used to build 3D model of ob

The system of Leap motion uses the right-hand cartesian coordinates. The returned values are in real-world millimeters [the same as the Kinect's depth data]. The origin point is at the center of the Leap Motion controller. The X-and z-ax

Screen time:creating vs. consuming
I think a lot of parents are worried that their children will spend a lot of time on computers, if they want to figure out whether they are "creating" or using computers, tablets, smartphones or even television.
Most parents choose to set screen time for their children, such as 15 minutes a day, and some can only play once a week. I am in favor of this, including playing games, watching entertainment video

the sparse or dense extent of the map points. For a simple example, sparse map is calculated by triangulation, with 1000 points in one bedroom enough; but dense map is typically a depth sensor for some active source (depth sensor, such as an ASIC in Intel's RealSense), Assuming that the resolution of each frame of depth sensor is 640x480, and even if there are 2/3 invalid depth, there are still 100,000 3D points, so the sparse map and dense map are usually two less than the order of magnitude.
