In recent years, both the RFID and computer vision technologies have been widely employed in indoor scenarios aimed at different goals while faced with respective limitations. For example, the RFID-based EAS system is useful in quickly identifying tagged objects but the accompanying false alarm problem is troublesome and hard to tackle with except that the accurate trajectory of the target tag can...
With the continuous development of modern surveying and mapping technology, robotics has been gradually adopted to achieve the autonomous digital measurements. In this paper, a mobile robot platform is designed and controlled to travel inside the Adit environment to collect data for 3D reconstruction and measurement. In traditional control applications, PID-based methods(PID) are widely used for the...
With the continuous improvement of people's life, the demand of 3D technology is not only restoring the real scene more scientifically, but minimize the discomfort of human eyes. Visual discomfort is caused by the distortion during the converting process of coordinate from the camera space to the display space in the entire imaging process. Through the analysis and simulation of the geometric distortion...
Based on the depth information acquired by the popular RGBD camera such as Kinect, the human body image areas in the infrared video can be selectively enhanced. In this paper, we firstly utilized the Optimal Contrast-Tone Mapping (OCTM) method instead of Histogram Equalization (HE) method to make a good contrast balance for the infrared video image acquired in a low illumination condition. Secondly,...
One method was proposed for recovering structure model of the object by using monocular vision equipment. The fundamental idea can be summed up as sequential reconstruction under hierarchical method. First of all, by dividing the single observation path into multiple, more details of structure can be observed. After outliers removing, these sequences can be aligned with the referenced one which can...
With the current booming development of 3D technologies, 3D capture has become one of the hot spots in multimedia, image and video field. In this paper, the common 3D capture mechanism is compared with the human visual mechanism. By analysis of the differences, the reasons of discomfort 3D visual perception of some captured 3D materials by the current capture devices are discussed, which would further...
This paper describes PowerBooter, an automated power model construction technique that uses built-in battery voltage sensors and knowledge of battery discharge behavior to monitor power consumption while explicitly controlling the power management and activity states of individual components. It requires no external measurement equipment. We also describe PowerTutor, a component power management and...
We introduce the first visual dataset of fast foods with a total of 4,545 still images, 606 stereo pairs, 303 3600 videos for structure from motion, and 27 privacy-preserving videos of eating events of volunteers. This work was motivated by research on fast food recognition for dietary assessment. The data was collected by obtaining three instances of 101 foods from 11 popular fast food chains, and...
