Description
Technical Field
The invention relates to the field of internet commerce, in particular to a target big data searching system based on a car rental order.
Background
Taxi, taxi departure is a very probative source. As early as the 18 th century, if a rich english person wanted to make a short trip, he often hired a one-horse two-wheeled buggy (cabriolet). The word Cabriolet comes from a French verb, meaning "jump". By the 19 th century, people began to refer to large cars in cities dedicated to hire by the abbreviated form of the word "cab", which is what we often say today as a taxi (catching a cab). In addition, taxis at that time, also known as hackneys or hasks, were taken from the french word haquesee (horse). To date, many taxi drivers in cities are still referred to as cockies.
Of course, there is no free lunch in the world, and it is also expensive to take a taxi. In the early days, taxi drivers charged fare based on estimated distance traveled. But by the late 19 th century, some have invented a taximeter (taximeter) that automatically measures the actual distance traveled by a vehicle, which word is taken from tax and mete in french (equivalent to tariff and meter in english). It is because of the invention and application of taximeters that taxis are soon being called taxicab, or taxi for short. The word is spelled in english, french, german, dutch, spanish, portuguese, swedish, denmark, norway.

Detailed Description
An embodiment of the object data search system based on a rental car order of the present invention will be described in detail below.
Application programs (applications) are one of the major categories of computer software, and refer to software written for a user's purpose. The application is again typically divided into two parts: a Graphical User Interface (GUI) and an Engine (Engine).
The concept of an application is different from that of application software. Application software refers to the classification of purposes used, and may be a single program or a collection of other dependent elements, such as Microsoft Office, Openoffice. An application refers to a single executable file or a single program, such as Word, Photoshop. The two may not be carefully distinguished on a daily basis. The program is typically considered an integral part of the software. An Application program (Application) operates in a user mode, which may interact with a user, typically with a visual user interface. What needs to be known about an application is: each application program runs in an independent process, and they have their own independent address space. The boundaries of different applications are called process boundaries.
At present, network booking orders become a main customer source of various taxies, and although the network booking mode provides convenience for taxi drivers and taxi renters, the taxi drivers feel troublesome that due to the imperfection or inaccuracy of a navigation system and the movement randomness of the taxi renters, the search for taxi renters who issue orders is a difficult task, and the energy of the taxi drivers is easily dispersed.
In order to overcome the defects, the invention builds a target data searching system based on the car rental order, and can effectively solve the corresponding technical problem.
The target data search system based on a rental order according to an embodiment of the present invention includes:
the information receiving terminal is used for acquiring the outline of the mobile terminal of the client who issues the current taxi order when the current taxi order is received;
the information receiving terminal is arranged on a meter panel of the taxi and establishes wireless link connection with each client issuing a taxi order through a taxi application program;
the content acquisition equipment is arranged behind a windshield of the taxi and used for executing image content acquisition action on the front environment of the windshield so as to obtain a corresponding front image of the windshield;
the data enhancement device is connected with the content acquisition device and used for receiving the image in front of the glass and executing image SVD enhancement processing on the image in front of the glass to obtain a corresponding data enhancement image;
the bicubic interpolation equipment is arranged in the information receiving terminal, is connected with the data enhancement equipment and is used for executing bicubic interpolation processing on the received data enhancement image so as to obtain and output a corresponding bicubic interpolation image;
the appearance comparison equipment is arranged in the information receiving terminal, is connected with the bicubic interpolation equipment, and is used for receiving the bicubic interpolation image, searching a terminal target matched with the appearance contour of a mobile terminal of a client issuing the current taxi order in the bicubic interpolation image, and outputting an area of the terminal target in the bicubic interpolation image as a target area when the depth of field of the terminal target in the bicubic interpolation image is smaller than a preset depth of field threshold value;
the data marking device is used for marking the target area in the bicubic interpolation image by a square frame so as to obtain a marking processing image;
and the real-time display equipment is connected with the data marking equipment, arranged in the information receiving terminal and used for receiving and displaying the identification processing image.
Next, a detailed configuration of the object data search system based on a rental car order according to the present invention will be described.
In the target data search system based on the taxi order:
and the appearance comparison equipment is also used for sending out a target undetected instruction when a terminal target matched with the appearance contour of the mobile terminal of the client issuing the current taxi order is not searched in the bicubic interpolation image.
In the target data search system based on the taxi order:
the bicubic interpolation equipment is realized by adopting a programmable logic device, and the programmable logic device is designed by adopting VHDL.
In the target data search system based on the taxi order:
the appearance comparison equipment is a bus type single chip microcomputer, and a timer and a ROM (read only memory) are arranged in the bus type single chip microcomputer.
In the target data search system based on the taxi order:
and the bicubic interpolation equipment and the appearance comparison equipment are in data connection and data interaction through a 32-bit parallel data interface.
In the target data search system based on the taxi order:

In addition, VHDL is mainly used to describe the structure, behavior, function, and interface of a digital system. Except for the fact that it contains many statements with hardware features, the linguistic form, description style, and syntax of VHDL are very similar to a general computer high-level language. The structural features of the VHDL program are to divide an engineering design, or design entity (which may be a component, a circuit module or a system) into an external (or visible part, and port) and an internal (or invisible part), which relate to the internal functions and algorithm completion of the entity. After an external interface is defined for a design entity, once its internal development is complete, other designs can invoke the entity directly. This concept of dividing the design entity into inner and outer parts is the fundamental point of VHDL system design. VHDL has powerful language structure, and can describe complex logic control by simple and clear source code. The method has a multi-level design description function, is refined layer by layer, and can directly generate circuit level description. VHDL supports the design of synchronous, asynchronous, and random circuits, which is incomparable with other hardware description languages. VHDL also supports various design methods, both bottom-up and top-down; the method supports both modular design and hierarchical design.
