A positioning device, used in antenna's testing system, includes a crane, a fastening device, a testing antenna and a laser generator. The crane includes a gearing with a sliding shoe thereon. The fastening device is fixed on the sliding shoe of the crane. The testing antenna is fixed in font of the fastening device. The laser generator is fastened on the fastening device and located on a level different from the testing antenna. The laser generator sends out laser for defining the position of the testing antenna.

摘要:
A method for zooming image shown in a touch screen includes reading information of a continuous writing locus formed on the touch screen; selecting a first group of points and a second group of points in the writing locus formed in time sequence; dealing with the first group and second group of points and obtaining a first radius and a second radius; comparing the first radius and the second radius to define a zooming command; executing the zooming command. A touch screen reading such writing locus into zooming command is also provided.
摘要:
An intelligent monitoring system aims to perform object surveillance and tracking, and can quickly build accurate and reliable background data in a complex image condition to achieve desired monitoring result. Based on a dynamic background and a temporary static object and user's requirements, monitoring objects in a background module can be added or deleted to match the actual background information. The whole background data can be tracked according to characteristics of a targeted object set by users, and post-processing can be done for the tracked object, such as zooming, identifying, capturing, surveillance of behaviors, and the like. Thus whether a special attention is needed for a dynamic or static object can be notified. And an alert can be issued to relevant people for timely handling.

A real-time alarm system comprises an image capturing element, a network transmission system, a control processing unit and a mobile device. The image capturing element is installed on different sites to generate image information. The image information is transmitted through the network transmission system with one end linking to the image capturing element. The control processing unit is linked to the network transmission system and includes a server, and contains preset information to compare with the image information to generate comparison information. The comparison information is analyzed by a preset algorithm to judge behaviors of objects in the images. The mobile device is linked to the control processing unit to receive the image information. After the control processing unit judges specific behaviors, it actively informs the mobile device to record a video for a selected duration to be seen anytime at a remote site.
