How To Use Kinect As A Camera On Pc
Motion Detection Software
3D motion detection software for the Kinect
This document explains how to use the Kinect camera to notice presence in Hot Spots in 3D space, and how to trigger actions and relay motion events to other software. This is useful for DIY projects, interactive media, and fifty-fifty for security.
Installation
The post-obit software/drivers must exist installed on the PC:
If you want to utilize an former Kinect for Xbox 360, you will need to install
Microsoft Kinect SDK 1.8
These devices may not be sold in stores much anymore, just can certainly exist found on classified ads.
Webcam Zone Trigger is the software that will connect to the Kinect and capture its 3D information.
Yous will need to run the software in "Pro" mode.
Webcam Zone Trigger Pro three.x
Installation details...
Download the drivers and software (listed above), connect the Kinect device on the PC. Make certain the Kinect is also powered from its DC connection.
The Kinect is ii cameras in 1
The Kinect provides both a "depth" image and a normal "color" image equally video sources. It is possible to acquire either or both. This can be useful for your project; this fashion you lot can run separate movement tests for both 3D and colors. You tin can also apply one source to test, and salve images or video on the 2nd source.
How to trigger Actions with 3D Hot Spots
Webcam Zone Trigger detects motion with a feature called "Hot Spots". A Hot Spot is a zone on the image that you specify, this is where the software volition look for move. You can specify many Hot Spots, and each spot tin can have a unlike Action to execute when it detects motion.
When the live stream is a Depth image, the Hot Spots are in "3D Presence" mode. You must first set it in 3D space:
- Create a new Hot Spot with the push button
- Movement and size the Spot on the image (*ane)
- Specify its distance from the camera (*2)
- Specify the Spot's depth (*3)
Whenever something moves in or out of the space occupied by the Hot Spot, the software will execute an Activity. Annotation that you also get to specify if the Hot Spot should execute the action when...
- The subject moves in the infinite
- The subject moves out of the space
- The bailiwick moves both in or out of the space
Advanced 3D Hot Spot scenarios
You might want to setup a more complex scenario than a single Hot Spot. With the software it is possible to have a whole array of Hot Spots in the space in front of the photographic camera.
- Create the first hot spot, as is described above.
- Click on the property button side by side to the spot proper name, select "Duplicate Hot Spot"
- Modify its name to something relevant. When yous have many Hot Spots on the screen it gets confusing.
- Move it and/or arrange its Distance from the photographic camera
- Go to step two and duplicate it over again
Example i. The subject area moves and trips Hot Spots
In the example to a higher place, a agglomeration of Hot Spots are gridded in space. Webcam Zone Trigger volition now exist able to tell where the subject is, and can perform action (play sounds, run commands) or relay this info to another software.
Instance 2. The Kinect is used equally a virtual bear upon-screen
In example 2, the Kinect is looking down in front of a screen. A agglomeration of Hot Spots have been placed in space one inch in front end of screen, aligned with the buttons on the display. Whenever the subject brings his hand well-nigh a displayed button, Webcam Zone Trigger will detect that the mitt is entering a 3D Hot Spot and volition relay this information to the software managing the display.
This organisation is likewise enlightened that someone is continuing in front of the display, using the Hot Spot placed where the subject should exist. This added bonus allows the interactive organisation to greet and guide the subject when he arrives.
When setting up 3D Hot Spots, information technology is much easier to do with help. 1 person is in front of the photographic camera and indicating where the Hot Spots should exist in space, someone else is at the computer moving, sizing and setting the depth distance for each Hot Spot.
At whatever time you can go back to adjust Hot Spots. Some Hot Spots may be overlapped by others and it may exist impossible to click on them, this is why there is a drop-list that lets you select a Hot Spot by name. Make sure you give relevant names to each new spot so that you can identify each in the list.
The Kinect tin can see in the night
One of the biggest problems with motion detection is that information technology is oftentimes vulnerable to light changes in the environment; the Sunday, shadows, or lights on/off in a room. Bad lighting can be a big trouble too, as this will compromise the image quality for most webcams.
The Kinect'south Depth paradigm, notwithstanding, does not rely on the environment's lite. It has its own infra-red laser projector, and this is all it needs to get a constant reliable 3D image. An interesting side-effect is that information technology tin browse in the dark, which makes it an interesting solution for security systems, likewise as interactive art projects.
Information technology is possible to use many Kinects on the same computer.
In the instance where you need to cover a large view, it is possible to take many Kinects working on the calculator at the same time, but there are a few weather:
- Since each Kinect has a projector, they cannot look in the same direction otherwise they volition interfere with each other.
- In social club for the aforementioned figurer to handle multiple video sources, Webcam Zone Trigger needs to exist running in "Pro" way, or with a Pro license.
- Each Kinect requires a certain amount of USB and CPU bandwidth. There is a limit the how many Kinects you lot can plug on a reckoner before overloading it. Y'all may need to experiment with the USB connections.
What about skeleton and gestures?
Webcam Zone Trigger is a general-purpose motility detection software, information technology does not procedure skeletons or gestures. If you are interested in having custom features added to this software, or if you need a completely new custom software, give us a call, we might be able to help.
