Traffic flow statistic and violation detection method based on surveillance video processing

The invention discloses a traffic flow statistic and violation detection method based on surveillance video processing. The method comprises the steps of obtaining a video source, reading a frame of image, judging if the current frame is a first frame, utilizing difference information of corresponding pixel points of the current frame and the previous frame to update foreground and background images if the current frame is not the first frame, utilizing the foreground and background images to extract an interest area MASK of the current frame, calculating integral images and integrated square images of the current frame, detecting in the interest area MASK of the current frame if a plate number target exists according to the obtained integral images and integrated square images of the current frame and utilizing an Adaboost algorithm, storing position information of the detected plate number target in a list TmpList, judging if the temporary target list TmpList is empty, judging if a tracking target sequence Track-List is empty if the temporary target list TmpList is empty, and adding the detected target in an ObjList into the Track-List if the tracking target sequence Track-List is empty. By means of the method, crossing traffic flow can be counted precisely, and if a vehicle target breaks the rule is judged combining indication of traffic signal lamps.

Uplink carrier scheduling method for carrier aggregation communication system, base station and user equipment

ActiveCN101835191AReasonable schedulingReduce error rateWireless communicationCarrier signalSignal-to-interference-plus-noise ratio
The invention discloses an uplink carrier scheduling method for an LTE (Long Term Evolution) carrier aggregation communication system. In the uplink carrier scheduling method, an eNb (evolved NodeB) configures all uplink CCs (Component Carriers) to UE (User Equipment) and configures an SRS (Sensing Reference Signal), the UE sends the SRS to the eNB through all the uplink CCs configured by the eNB, the eNB measures the SINR of the UE on each uplink CC based on the SRS sent by the UE, and the eNB judges whether the SINR (Signal to Interference Plus Noise Ratio) of the uplink CC exceeds a preset threshold; and if so, the eNB schedules the UE to carry out transmission on the uplink CC, or else, the eNB does not schedule the UE to carry out transmission on the uplink CC. The invention also discloses the eNB and the UE in an LTE carrier aggregation communication system. By using the uplink carrier scheduling method, the eNB and the UE, the eNB can clearly know the quality of the UE on each uplink CC, so that the eNB can make a decision based on the quality the uplink CC when judging whether to schedule the UE to carry out transmission on the uplink CC, thereby being capable of reasonably scheduling the uplink carrier.
