Abstract
The invention discloses an automatic-search fake plate time threshold value configuration algorithm based on adjacent gates. The automatic-search fake plate time threshold value configuration algorithm based on the adjacent gates comprises the steps that a gate list needing to be set is acquired, selected road network data are graded, and the speed value of vehicle traffic of roads of each grade is set; the set target gate range is converted into the longitude and the latitude, and then gates within the set longitude and latitude range are screened out through the X-axis and the Y-axis of the gates; the distance between a target gate and each gate within the range is analyzed according to the road network data; eight directions are divided by using the target gate as the origin of coordinates, the angle in each direction is 45 degrees, the angle of each gate with the range and the target gate is calculated, and the gates within the range are grouped according to the angles; a gate, meeting the requirement that the distance between the gate and the target gate is smallest, of each group is selected as the adjacent gate; the time threshold value of each distance is calculated according to the corresponding speed value set by the road network data; the results obtained through calculation are stored in a database. The purposes that the adjacent gates are automatically searched for and analyzed, and distance between the two gates is automatically calculated according to road networks, so that the fake plate time threshold value between the two gates is obtained are achieved.
Description
Technical field
The present invention relates to a kind of based on contiguous bayonet socket Automatic-searching deck time threshold placement algorithm.
Background technology
Fake license plate vehicle analysis has become one of important actual combat business of current public security, and the time comparative analysis method based on bayonet socket analyzes the major calculations method of fake-licensed car.Time comparative analysis method based on bayonet socket needs the time threshold values of contiguous bayonet socket.The mode arranging threshold values at present mainly or by manually marking and drawing based on generalized information system arranges adjacent bayonet socket.Along with the quantity of newly-built bayonet socket increases day by day, the mode manually arranging threshold values can not meet the computing that deck analyzes business gradually.
Adjacent card muzzle board threshold values is manually set and there will be following problem: 1), due to efficiency comparison when bayonet socket quantity excessive use is manually arranged low; 2), use manually arranges the bayonet socket easily missed some and do not arrange.
Summary of the invention
The invention provides a kind of based on contiguous bayonet socket Automatic-searching deck time threshold placement algorithm, full-automation can be realized and search the contiguous bayonet socket of analysis and automatically calculate the distance between two bayonet sockets by road network thus draw the deck time threshold values between two bayonet sockets.
The present invention is realized by following technological means:
Based on a deck time threshold values placement algorithm for contiguous bayonet socket Automatic-searching, it is characterized in that:
S1, acquisition needs carry out the bayonet socket list arranged, and carry out classification and set the current velocity amplitude of every grade of road vehicle to the road net data selected;
S2, the target bayonet socket scope of setting is converted to longitude and latitude respectively, then by bayonet socket
X, Y-axis filter out the bayonet socket within the scope of the longitude and latitude of setting;
S3, distance according to each bayonet socket in described road net data evaluating objects bayonet socket to scope;
S4, with target bayonet socket for true origin divides eight directions, each orientation angle is 45 °, the angle of computer capacity inner bayonet and target bayonet socket, and is angularly divided into groups by the bayonet socket in scope;
S5, to select in each group with the shortest bayonet socket of target bayonet socket distance as contiguous bayonet socket;
S6, the velocity amplitude set by described road net data calculate the time threshold values of every segment distance.
Wherein, described computer capacity be grouped into 0 °≤angle <45 °, 45 °≤angle <90 °, 90 °≤angle <135 °, 135 °≤angle <180 °, 180 °≤angle <225 °, 225 °≤angle <270 °, 270 °≤angle <315 °, 315 °≤angle <360 °.
By above method, achieve full-automation and search the contiguous bayonet socket of analysis and automatically calculate the distance between two bayonet sockets by road network thus draw the deck time threshold values between two bayonet sockets.

Embodiment
Below with reference to accompanying drawing, specific implementation process of the present invention is described in detail.
Based on a deck time threshold values placement algorithm for contiguous bayonet socket Automatic-searching, as shown in Figure 1, obtain the bayonet socket list needing to carry out arranging, classification is carried out to the road net data selected and sets the current velocity amplitude of every grade of road vehicle; Then the target bayonet socket scope of setting is converted to longitude and latitude respectively; Then the bayonet socket within the scope of the longitude and latitude of setting is filtered out by X, Y of bayonet socket; Then according to the distance of each bayonet socket in road net data evaluating objects bayonet socket to scope; Then with target bayonet socket for true origin divides eight directions, each orientation angle is 45 °, the angle of computer capacity inner bayonet and target bayonet socket, and is angularly divided into groups by the bayonet socket in scope; Described computer capacity grouping be divided into as shown in Figure 20 °≤angle <45 °, 45 °≤angle <90 °, 90 °≤angle <135 °, 135 °≤angle <180 °, 180 °≤angle <225 °, 225 °≤angle <270 °, 270 °≤angle <315 °, 315 °≤angle <360 °; In each group, finally select the bayonet socket the shortest with target bayonet socket distance as contiguous bayonet socket; The time threshold values of every segment distance is calculated by the velocity amplitude of road net data setting; The result of calculating is saved in database.
More than achieve full-automation search the contiguous bayonet socket of analysis and automatically calculate the distance between two bayonet sockets by road network thus draw the deck time threshold values between two bayonet sockets.
The scheme of simple change gained is carried out also within protection scope of the present invention to the present invention.
