The invention relates to a method for avoiding a collision as a vehicle is changing lanes to a target lane, during which objects in a lateral rear space of the vehicle are detected by means of a surrounding area monitoring device and measures for influencing the vehicle are initiated. The method is characterized in that stepped measures are provided, these measures comprising, according to their step, a warning of the driver and / or an intervention in a steering system of the vehicle (1) and / or an influencing of safety means, and that the measures of a selected step are initiated. The step is determined according to a relative position of a detected object with regard to the vehicle and / or a relative velocity between the vehicle and the detected object as well as according to the fulfillment of a lane change condition. The invention also relates to a device suited for carrying out the aforementioned method.

The invention discloses a scene visualization intelligent construction site management system based a three-dimensional model, and the system obtains the data of a person and a vehicle according to the card swiping information of an access control system, and obtains the scanning data of a corresponding fixed person and set mechanical equipment through scanning a bar code. A plurality of cameras disposed on a construction site are used for obtaining the real-time video monitoring data of the construction side. An environment monitoring device disposed on the construction site is used for obtaining the corresponding environment data. An information real-time broadcasting system enables the obtained public broadcast data to be transmitted to an information broadcast database. Based on the technology of intelligent construction site management, the visualized scene of the system is displayed and integrated on the basis of the three-dimensional model, and the display, analysis, processing and analysis of the obtained data of the system are carried out. Meanwhile, the system is integrated with the existing project management system and database, thereby achieving the decision support for project management, the bias early warning for a project, and the feedback of project experience and information.

An environmental monitoring device that includes an acoustic sensor is described. During operation of the environmental monitoring device, the acoustic sensor provides acoustic data based on measurements of sound in an external environment that includes the environmental monitoring device. Based on the acoustic data, a control mechanism determines if an alarm device, which is separate from the environmental monitoring device, is activated. For example, the environmental monitoring device may determine if a smoke detector is activated based on measurements of sound, such as a temporal 3 acoustic pattern. In addition, a sensor mechanism in the environmental monitoring device may provide sensor data based on measurements of an environmental condition in the external environment. The control mechanism may use the sensor data to assess a degree of threat in the external environment, and the environmental monitoring device may output different audible sounds as the degree of threat changes.

A vehicle environment monitoring device comprises an imaging section for taking image data of an environment of an automobile, the image including at least two types of colors; a setting section for setting a specific area of the image data obtained by the imaging section, wherein the specific area has a strip shape longer in, and parallel to, a horizontal direction of a frame image and includes at least two types of colors; an extraction section for taking in image data of the specific area in units of one or a plurality of frame images taken by the imaging section in time series and extracting moving vector information based on the image data of the specific area; and a detection section for detecting a second vehicle which is present in an environment of a first vehicle having the vehicle environment monitoring device mounted thereon, based on the moving vector information.
