车辆通行费自动支付方法

The automatic vehicle toll paying method includes the vehicular portable phone to log in the specific automatic toll gathering number before entering the charged highway or bridge; the vehicular portable phone to log out the specific automatic toll gathering number after leaving from the charged highway or bridge; the cellphone base station to inform the charging center to deduct the toll from the account number of the portable phone; the charging center, after successful deducting, to transmit the successful payment information as electronic payment credence to the portable phone via the cellphone base station.

Method for plucking license-plate region from vehicle image

The present invention relates to a method for picking license plate region from car image. Said method mainly includes the following steps: calculating horizontal gradient and vertical gradient of car image to produce horizontal gradient image and vertical gradient image; binarizating the horizontal gradient image and vertical gradient image to obtain horizontal gradient binarizated image and verticalgradient binarizated image so as to make the numerical value of every pixel in image only be high value or low value; then combining horizontal gradient binarizated image and vertical gradient binarizated image into integrated gradient binarizated image; collecting adjacent high value pixel group in the integrated gradient binarizated image into license plate candidate region, then defining every license plate candidate region to produce defined license plate region image.

以电话预付卡扣缴停车费的停车场管理系统

The invention is a park management system using telephone prepayment card to withhold parking fee, making drivers pay by mobile telephone prepayment card/public telephone IC card/international telephone prepayment card; and mainly composed of vehicle detector, passageway camera, photo taking module, number board identifying module, entrance information generating module, exit data check module and fence machine control module, vehicle video database, vehicle traffic database, payment database, leaving database, dial communication module, fee recording module and error processing module.

Combined type on-board unit for open type electronic charging

This invention relates to open electron charging compound car, which comprises one central process module, global satellite positioning module, mobile communication module, signal column communication module, IC card interface module and information output module, wherein the central process module receives the positions and time materials from global satellite positioning module and compares the received materials with the pre-set charging area and when the results meets, it controls the IC card interface to remove the electron money and sends the audits to the account system to fulfill the car charging automatic program.

车辆通行费自动计收费方法

The automatic vehicle toll charging and paying method is to use cell phone for log-in and log-on of the vehicle toll. Before entering the charged highway or bridge, the vehicular portable phone to log in the specific automatic toll gathering number to store the portable phone number and vehicle license plate number related information in the charging center. After leaving form the charged highway or bridge, the vehicular portable phone logs out the specific automatic toll gathering number, and all the cell phone codes the portable phone system passes through in the period between the log-in and the log-out are used in charging the toll.

Digital image monitoring control system capable of automatic adjusting lens diaphragm and detecting object movement

Digital image monitoring control system capable of automatic adjusting lens diaphragm and detecting object movement

The system comprises assorted lens, image catching card for catching digital image of the object to be catched by CCD video camera. The catched image is decomposed of by image brightness-reflectance decomposition unit to be two parts of spectrums as brightness and reflectance and image brightness variation detecting unit is provided to analyse bright ness spectrum variable of two continuous images as well as to use this variable to control the enlarging or reducing of the iris diaphragm. In addition, object motion detecting unit is provided to analyse reflectance spectrum variable of two continuous images, which is used to judge whether object in image picture is moved or not in order to have correct judgement for state of the object motion.

智能型交通运输管理系统及其管理方法

The invention is a intelligent traffic transmission managing system and the managing method, which includes user charging the mobile phone into the one with highway electron charging application service mobile phone, mobile communication base stations and ETC account system, when the user enters the entrance of the highway, and leaves the highway through the outlet, the ETC account system works out the fee correspondent the traveling miles through comparing the telecom service operation recorded cell incrimination code to the electron map, and charging in the next month action fee in the memory databank.

影像二值化方法

The invention is a image two-value method, which includes (1) calculates all the occurrence times of all the values of the pixels to paint the accumulating column histogram of pixels, the beam of the accumulative histogram is the arrangement of all the probable values of pixels from little to big, the lengthwise is the accumulative occurrence times less than or equal to the value pointing each value; (2) finds out a value between the maximum and the minimum, makes the occurrence times of the minimum value, the accumulative times less than or equal to the value, the accumulative occurrence times less than or equal to the maximal value from a linear fold most approached accumulative column histogram, which is defined as the criteria value of the pixel value; (3) the pixel value more than criteria value is changed into high value, the pixel value less than or equal to the criteria values are changed into low values in order to acquire the two-value process to image.

Method for detecting moving object in image

A method for detecting object movement in image includes calculating out variant image of current image to background image for finding a two valued critical value in absolute value distribution of all picture elements in the variant image, correcting image variant caused by light change with picture element value below or equal to two valued critical value in order to obtain the corrected variant image, confirming that high value image is the image of object movement after corrected image is two-valued.
