An intelligent environment employing multiple vision sensors labeled with identification features is proposed. The union of the sensing ranges of these vision sensors covers a large unknown workspace where a mobile robot can proceed to explore. The goal of this research is to accomplish mobile robot localization and navigation based on such a calibration-free sensor network. Specifically, stati...

In this paper we present methods for characterizing CCD cameras. Interesting properties are linearity of photometric response, signal-to-noise ratio (SNR), sensitivity, dark current and spatial frequency response (SFR). The techniques to characterize CCD cameras are carefully designed to assist one in selecting a camera to solve a certain problem. The methods described were applied to a variety...

The aim of this paper is to describe the data-fusion acquired from a CCD camera and a thermal imager. The fusion is realized by means of spatial data from a TOF camera to ensure ”natural” representation of a robot’s environment; thus, the thermal and CCD camera data are comprised in one stereo image presented to a binocular, head-mounted display. The data acquisition is performed using a sensor...

سنجنده ccd camera یک سنجنده چند طیفی است که بر روی ماهواره cbers02 نصب شده است. تکنیک تصویربرداری در این سنجنده به صورت پوش بروم می­باشد. در تصاویر اخذ شده توسط سنجنده ccd camera برخی نویز­های نواری عمودی دیده می­شود که علت آن عدم تطابق پاسخ طیفی آشکارسازها، تغییرات درونی آشکارسازها، واسنجی نامناسب سنجنده و پایین بودن نسبت سیگنال به نویز می­باشد. این نویز در تصاویر دریافتی از سطوح همگن که در سط...

Fig.1 Measurement system In this paper, the three-dimensional surface shape measurement system with the temperature information is introduced. The measurement is established using a three-dimensional surface measurement system and a thermography. The measurement system is composed of CCD camera, a laser and thermography. The laser is projected to the object and the laser streak image appeared o...
