There are numerous scenarios where the photographer is in difficulty and unable to capture or shoot video as required. This could be due to several factors such as limited space, decreased visibility, and an obstacle in the way. Therefore, this project implements the idea to capture and shoot video of the desired subject through an automatically controlled robotic camera with no need for a photographic bloke. The system comprises functions such as detection, tracking, live streaming, and video/audio recording along with the features of Radio-Frequency-Identification (RFID). Therefore, this robotic camera will detect the desired subject, track and focus it with the help of its position driven through movable motors sensing the RFID tag in case the object is non-stationary. The video/audio will be recorded on a computer along with the live streaming available on an Android-based device. The Viola-Jones algorithm of the image processing technique is used to detect the particular subject features and C for accessing the movable camera protocols. The RFID transmitter and receiver are used to sense the RFID card and serve the purpose to track the subject using the algorithms of image processing, with the advantage of ignoring other obstacles between the camera and the detected subject. Thus, adding a novel functionality to the existing systems, that lacks the feature of focusing the camera on the subject, when an obstacle is detected in between. The live streaming is achieved wirelessly through an open-source platform X-operating system, Apache, MySQL, Php, Perl (XAMPP). The idea is verified through concluded arrangements in self-made scenarios in response to the speed, distance, light, and background noise of the detected subject, which delivered encouraging results. Therefore, the designed system can be used for live conferences, seminars, and other multimedia-required arrangements.
在许多情况下,摄影师会遇到困难,无法按要求拍摄照片或视频。这可能是由于多种因素造成的,比如空间有限、能见度降低以及有障碍物挡道。因此,本项目实施了一个想法,即通过自动控制的机器人相机来拍摄所需对象的视频,而无需摄影师在场。该系统具备检测、跟踪、直播以及视频/音频录制等功能,还带有射频识别(RFID)功能。所以,这个机器人相机将检测到所需对象,在对象非静止的情况下,借助可移动电机驱动其位置并感应RFID标签,从而对其进行跟踪和聚焦。视频/音频将记录在计算机上,同时在基于安卓的设备上进行直播。图像处理技术中的Viola-Jones算法用于检测特定对象特征,C用于访问可移动相机协议。RFID发射器和接收器用于感应RFID卡,并利用图像处理算法来跟踪对象,其优势在于可以忽略相机与检测到的对象之间的其他障碍物。这样,就在现有系统中增加了一项新功能,当在相机与检测对象之间检测到障碍物时,现有系统缺乏将相机聚焦在对象上的功能。直播通过开源平台X操作系统、Apache、MySQL、Php、Perl(XAMPP)无线实现。通过在自制场景中针对检测对象的速度、距离、光线和背景噪声进行的既定安排验证了这一想法,取得了令人鼓舞的结果。因此,所设计的系统可用于现场会议、研讨会以及其他需要多媒体的安排。
