  • Kinect V2 Case Study

    the Kinect’s algorithms will try to guess the current po- sition of the occluded limb. Furthermore this occlusion would also disallow the control this limb. A suitable solution was presented by Cui, Schuon, Chan, Thrun, and Theobalt, 2010, combining multiple Kinect’s, tracking the subject from different perspectives. It should be noted that combining multiple time-of-flight (TOF) cameras in realtime does not go with- out penalty. Should the infrared points, sent out by multiple Kinects (See figure 3.3, page 18), become overlapped by each other, the two points will be indistinguishable, resulting in 18 3. Optical depth-finding motion-sensing prototype measurement errors. Butler et al., 2012 demonstrates a solution for this limitation, by blur- ring the other Kinect’s infrared dots. This blurring can be achieved by introducing micro movement to the Kinect, for example by attaching an eccentric rotation mass. This shaking will cause for the Kinect to see all other TOF points blurred, whilst seeing it’s own sharp. Figure 3.3: Cloud of infrared dots, send out by a Microsoft Kinect camera. The time-of-flight is measured by the camera’s CMOS sensor. As research by Huston and Liu, 1994 suggests, combining the relative coordinate sys- tems will require us to know the exact relational position and rotation between two cam- eras. Theoretically this position can be measured and entered manually when using fixed camera positions, but accurately measuring is tedious and has a large room…

    only the black line. Object following robot: Finally, lets create a obstacle following robot. As like the other switch robots, for object following robot, we need to place the sensors at the front side of the robot. each robot creation, will be involved with a certain concept from our general Physics and some times, we experience them in our daily routine too, but we couldn’t relate them. Now, let’s try understand the concepts involved in this robot creation. In this robot, we have implemented 4…

  • Homer Simpson's Thermal Radiation?

    start by talking about the thermal radiation. Thermal radiation is energy where it transfers by the emission of electromagnetic waves. The waves hold energy away from releasing object. For a normal temperature, the radiation is in the infrared region of the electromagnetic spectrum. The relationship ,conducting the net radiation from a hot object is called,” Stefan Boltzmann Law.”In 1879, it empirically obtained by Josef Stefan. In 1884, it was obtained theoretically…

  • Bluebot Lab

    What types of light can a light sensing BlueBot detect? Lights are used for many everyday tasks, and many days they go unnoticed. There are many types of lights, such as Ultraviolet, Infrared, fluorescent, and LED lights, and they all can do different things. Ultraviolet light can be used as a way to light up certain types of clothing, or it can be used to sterilize food. Infrared light is mainly used as a way to heat up food, or as a shorter wavelength to control household items, such as…

  • Polar Bear Essay

    of CO2 into the atmosphere and that gas captures the infrared red which causes global warming Three scientists in the 19 century have studied infrared radiation and its effects on global warming. A German astronomer, Frederick William Herschel, discovered infrared radiation on February 11, 1800. Herschel used a prism to separate the different wavelengths and noticed that the wavelength with the highest temperature was beyond the red visible light portion of the visible light spectrum. This means…

Hagting & M. van Zuylen Abstract Luminol was synthesized and the light intensity of its luminescence was tested. The yield of the synthesis was 55%. Measurements of the intensity of luminescence were done under standard and optimal conditions resulting in peak intensities of ±0.02 lux (standard) and ±0.03 lux (optimal). It has been…

    by trudging across scorching deserts on camels, guided by tattered maps" (Juan De Los Santos, Search for Anicent Civilizations, Paragraph 1). This quote shows that the explorers would travel on foot or animals, depending where they were, and try to find an ancient place or artifact. This technique wasn't that great with finding things and it took a long time. In 2011, most explorers turned to infrared satellite archeology. "Infrared stellite imagery detects these differences in density,…

    According to Fankhauser et al. (2015), there is a general consensus that the first version of Microsoft Kinect is a depth sensor that quickly returns high-resolution depth images for a low cost. The original version of the Kinect 3D camera uses a real-time algorithm to calculate distance by triangulation using randomly-projected infrared light beams (Chen, Yue, Wu, & Wang, 2014), and presents point-like depth readings in the form of point clouds (Stefanczyk et al., 2013). According to…

    invention of this new apparel, that can support the body to remain cool from these strong UV rays. Visible light is in the middle of the EM spectrum. “Visible light is the smallest region of the EM spectrum. It is the only spectrum of the EM radiation that we can actually see. It also separates the damaging from the non-damaging EM radiation (Kudurna “CHM 110 Required Note Packet”).” In terms of the article, researchers are attempting to reconstruct, polyethylene, a fabric that is transparent to…

  • Brazil Pronunciation Report

    This report will highlight the difference in vegetation change from 1991 to 2011 in the southern Amazonia of Brazil. The report will do this by outlining what NDVI is and how it is derived and then analysing the specific results of Brazil. NDVI stands for Normalised Difference Vegetation Index and usually derived from satellite data, for landsat data this is usually thirty metres above the ground, to classify land cover change over a continental scale (DeFries and Townshend, 1994). When light…
