Kinect IR sensor resolution - Google Groups

19/11/2010· Re: Kinect IR sensor resolution. Zsolt Ero. 11/18/10 6:28 AM. For me it would make sense if the. 1. emitter had 640x480 resolution (I mean 640x480 small IR dots) 2. sensor had about 2-3x times that resolution (1600x1200 is about that) 3. the depth image (640x480) would contain a Z value for every single dot emitted.

A Tutorial on Electro-Optical/Infrared (EO/IR) Theory and ...

EO/IR sensor is integrated. Performance of an EO/IR sensor depends upon the optics, detector, and display, in addition to factors mentioned it is unwise to evaluate the potential utility of an EO/IR sensor from specifications alone, that is, without using a detailed engineering model. Nevertheless, all other things being equal, it can be argued that, for an imaging sensor designed ...

What is the resolution and sensitivity of the sensor

03/08/2021· In actual work, in addition to dynamic characteristics, the sensor also has resolution and sensitivity. Today, I will give you a detailed introduction to what resolution and sensitivity are. 1. Resolution Resolution refers to the ability of the sensor to feel the smallest change in the measurement. When the input change value is within a certain range, the output of the sensor will not …

Resolutions of Remote Sensing - University of Rhode Island

Spatial resolution of images acquired by satellite sensor systems is usually expressed in meters. For example, we often speak of Landsat as having “30- meter" resolution, which means that two objects, thirty meters long or wide, sitting side by side, can be separated (resolved) on a Landsat image. Other sensors have lower or higher spatial resolutions. Comparison of Landsat Sensors Thematic ...

Sensor resolution (spatial) Some ... (mainly used for IR), pyroelectric detectors, and microbolometer detectors. The ability of such a detector to resolve those differences depends mostly on the size of the detecting elements. Spatial resolution is typically expressed in line pairs per millimeter (lppmm), lines (of resolution, mostly for analog video), contrast vs. cycles/mm, or MTF (the ...

IR (Infrared) Obstacle Detection Sensor Circuit

02/02/2015· An IR sensor consists of an IR LED and an IR Photodiode; together they are called as Photo – Coupler or Opto – Coupler. When the IR transmitter emits radiation, it reaches the object and some of the radiation reflects back to the IR receiver. Based on the intensity of the reception by the IR receiver, the output of the sensor is defined. Obstacle Sensing Circuit or IR Sensor Circuit. A ...

What Defines Sensor Resolution? - Applied Measurements Ltd

The resolution itself is derived from the electronic equipment that measures the signal from the sensor, ie a voltmeter. It is important to determine accuracy, especially with pressure sensors. There are many factors that influence the output signal (linearity, hysteresis, repeatability, temperature effects etc), all of which depend on how the sensor is used.
