Border-crossing detection method based camera angle

InactiveCN104978751AReduce work intensityImprove monitoring proactivenessImage enhancementImage analysisLine segmentSafety signs
The invention discloses a border-crossing detection method based a camera angle. The method comprises the steps: firstly acquiring an included angle alpha and an included angle beta; obtaining a closed border line and a safe channel line section according to the peak of the border line and the end point of the safe channel line section arranged by a user; expanding and reducing the closed border line to obtain a tracking region; then carrying out moving target detection on every frame of a video monitoring image and screening the moving target region located in the tracking region; then matching and tracking the screened moving target region and the tracking target to obtain a coordinate queue of the tracking target; correcting the center of mass of the tracking target according to the included angles alpha and beta; then carrying out target behavior analysis on the tracking target according to the center of mass; judging whether border-crossing dangers exist or not, if the border-crossing dangers are great, alarming; otherwise, judging whether the current abnormal condition needs to be pre-warned or not according to a safety sign. According to the method disclosed by the invention, adaptive changes are available according to different angles of the camera during target behavior analysis, so that the robustness of border-crossing detection is improved.

Fountain type traffic safety partition warning system

A fountain type traffic safety partition warning system is composed of circulatory fountain devices which are connected successively through pipes. Each of the circulatory fountain devices is composed of a water tank, filters, a reservoir, water pumps and spray nozzles. Grating covers which are sunken and hidden under road surfaces are added on the water tanks. Water in the water tanks are filtered by the filters, flows into the reservoirs and is delivered to the water pumps through pipes; circuit control switches are connected with lighting lamps and the water pumps through wires and control the lighting lamps and the water pumps to spray water in the reservoirs into water patterns of required heights and lengths in rows, so that a row of fountain type traffic safety partition warning system is formed above the road surface and lightened by lighting lamps to be in striking colors; and sprays flow into the water tank through holes of the grating cover after falling to be recycled. The system can be longitudinally mounted at the center of a road to serve as a central partition railing to partition lanes in two directions; the system can be used as the partition railing and lane marking lines; the system can be transversely mounted on a pedestrian crossing and cooperate with traffic lights to serve as a passing gate of the pedestrian crossing; and safety signs are projected through a projector, so that the system can be used as a traffic safety warning sign to warn and remind traffic participator.

Emergency safety marker systems

An electronic lighted safety marker system used by emergency responders to warn motorists of the presence of an accident scene ahead on or beside the roadway is provided by the invention. Such safety marker can be deployed individually or in groups by the emergency responder along the perimeter of the accident scene and ideally ahead of it along the roadway to provide adequate warning to approaching motorists to avoid the accident scene. The safety marker contains a power source, a light panel, a protective shield for the light panel, and electronic circuitry for controlling the operation of the lights in a predetermined frequency or pattern, and may be automatically actuated and self-righting when it is dropped onto the ground or other hard surface. The safety marker further includes a transmitter for sending a signal to a receiver. Upon impact with the safety marker, the signal ceases and the receiver, equipped with an alarm, triggers either or both of an audible or visual signal. The safety marker can also contain an incursion warning system against incoming vehicles, an early warning radar transponder for sending a warning message to such incoming vehicles, a GPS location detector and transmitter for providing the location of the safety marker and its associated accident scene to a central dispatcher, and a gunshot sensor for detecting the occurrence of gunfire around the accident scene and its location to provide that information to the central dispatcher.

Virtual machine access control system and method based on cloud computing environment

The invention discloses a virtual machine access control system and method based on cloud computing environment. The method comprises the steps of judging whether a mounting protocol of a virtual machine conforms to a mounting protocol of a physical resource server or not; judging whether a resource pool required by a command sent by the external virtual machine exists in a storage pool or not; if the resource pool exists, opening and decrypting the resource pool inside the storage pool; if the resource pool does not exist, creating and encrypting the required resource pool; creating the required resource pool and a corresponding safety sign, judging whether the safety sign of the resource pool conforms to the matching principle or not, and when the safety sign of the resource pool conforms to the matching principle, judging whether the attribute of the safety sign of the resource pool needs to be modified or not; opening and decrypting the existing resource pool; when decryption succeeds, judging whether the safety sign of an access process of the external virtual machine is matched with the decrypted safety sign or not, and calling a result output module. According to the virtual machine access control system and method based on the cloud computing environment, a host machine and the virtual machine can be isolated from each other according to the matching rate of the signs, the resource pool encryption method and the mounting protocol of the storage server.

Water leakage prevention sealing strip for cable pit cover plate

The invention discloses a water leakage prevention sealing strip for a cable pit cover plate. The sealing strip mainly comprises a sealing strip base (1) with a T-shaped longitudinal section, and is characterized in that a plurality of layers of symmetrical or asymmetrical waterproof tooth edges (3) are arranged on the two sides of an insertion trunk (2) of the T-shaped sealing strip base (1). The sealing strip has the advantages that 1, a flame-retardant modified fluorosilicone material is elastic, and the waterproof tooth edges (3) are bent into V-shaped security strips, and are tightly attached to the wall of seams (7), so that water leakage and the inflow of foreign matters are prevented in multiple levels, a good sealing effect is achieved, the interior of a pit is kept clean, safety is ensured, and the pit can be inspected and accepted once; 2, the sealing strip is convenient to mount and replace, so that simplicity and convenience in power inspection, maintenance and first-aid repair are ensured; 3, the flame-retardant modified fluorosilicone material is nontoxic, fireproof and flame retardant, and the sealing strip is convenient to construct and reusable, and is an environment-friendly product; and 4, color can be used as a safety sign for the sealing strip, and a good effect is achieved.
