Description
Technical field:
The present invention relates to data acquisition system (DAS), more specifically relate to the scenery data acquiring system of a kind of acquisition time simultaneously and coordinate information.
Background technology:
The application of open-air landscape data often needs and the combining of time and latitude and longitude coordinates information, and open-air landscape data information is scientific research and the necessary basic informations of production practices such as the investigation of agricultural production, soil utilization, ecologic environment and disaster and monitoring.
At present to needing the open-air scenery data acquiring of time and latitude and longitude coordinates information, general ordinary camera combining global positioning system (the Global Position System that adopts, be called for short GPS), the method that writes down by hand and number is determined the time and the latitude and longitude coordinates information of open-air landscape data.Open-air landscape data is gathered in the cooperation of also useful video camera and GPS, as: " System and method for of carrying out field information acquisition, location and handling " patent No.: 98125290.7, the method for sampling of these systems exists following deficiency:
1, needs with not recycling consumptive materials such as a large amount of films or camera tape, expense costliness.
2, the collection of data and complex disposal process are loaded down with trivial details, need cost great amount of manpower and time, because manual intervention is too much, make mistakes easily.
3, the data post-processed work period of Cai Jiing long, be unfavorable in the short project of agricultural feelings speed newspaper, resource quick checking equal time cycle request, using.
Summary of the invention:
The scenery data acquiring system that the purpose of this invention is to provide a kind of acquisition time simultaneously and latitude and longitude coordinates information.Open-air landscape data energy automatic match time information and the latitude and longitude coordinates information of this system to gathering, easy to operate, quick, accurate.
In order to achieve the above object, the present invention adopts following technical scheme: digital camera passes through USB (universal serial bus) (universal serial bus with the image information of obtaining, abbreviation USB) is transferred to notebook computer, the image notebook computer that obtains is named by the method that numeral increases progressively automatically, and manually imported the view type identification; Notebook computer is by RS232 communication interface while receiving world locational system (Global Position System, abbreviation GPS) temporal information and latitude and longitude coordinates information, the image information, image name, view type identification, temporal information and the latitude and longitude coordinates information that receive are mated voluntarily, and generate a record and deposit in the database, and can on screen, show the information of coupling.
The present invention compared with prior art has the following advantages: the latitude and longitude coordinates positioning error is little, and temporal information and latitude and longitude coordinates information in time are identified on the image by notebook computer, do not need consumptive materials such as film, camera tape; The collection and the processing procedure of data are simple, and the sign of the time of image and latitude and longitude coordinates information can realize automatically, is difficult for makeing mistakes; The data post-processed work period of gathering is short, adapts to the application of agricultural feelings speed newspaper, the shorter project of resource quick checking equal time cycle request.
Description of drawings:
Fig. 1 is the structured flowchart of the scenery data acquiring system of a kind of while acquisition time and latitude and longitude coordinates information.
Fig. 2 is the integrated block diagram of the scenery data acquiring system of a kind of while acquisition time and latitude and longitude coordinates information.
The present invention is further illustrated below in conjunction with accompanying drawing.
As shown in Figure 1, gps antenna and GPS OEM plate form the GPS receiving instrument, receive The time of GPS and latitude and longitude coordinates information are sent to pen by the RS232 serial communication interface Remember in this computer; The same time of image information that digital camera is gathered is by the USB high-speed interface Be sent in the notebook computer.
The workflow of system is as shown in Figure 2: at first start computer, initialize com port and The GPS receiving instrument is opened digital camera, setting data acquisition time interval on notebook computer, The GPS receiving instrument enters duty, and simultaneity factor is carried out status monitoring to the GPS receiving instrument, as Fruit GPS receiving instrument is working properly, and system reads its time that receives and latitude and longitude coordinates letter Breath is written to the system works internal memory; If the work of GPS receiving instrument is undesired, then enter warning System carries out artificial debugging, misarrangement, reinitializes the GPS receiving instrument again. Receive at GPS In the time of instrument work, the image information of digital camera picked-up writes notes by the USB high-speed interface Another work internal memory of this computer also shows at display screen. Notebook computer is with in the above-mentioned work Image information in depositing, gps time information and latitude and longitude coordinates information are mated, and are identified at Show on this image and at notebook computer. At this moment, utilize the time of gathering the next frame image The corresponding landscape types sign of this image is imported by keyboard of notebook computer in the interval, and with The image information that notebook computer obtains, temporal information, longitude and latitude coordinate information and automatically generation Image name be written in the database as a record. After this record generates, notebook Computer removing work internal memory carries out the collection of lower piece image and the reception of GPS information.
Embodiment:
1, the hardware of the present invention's employing
(1) USB (universal serial bus) (universal serial bus is called for short USB)
USB (universal serial bus) (USB) is a kind of peripheral bus standard of being developed jointly by companies such as IBM, Compaq, Intel, Microsoft, is used for the exchanges data between computing machine and the peripheral hardware.When being located at the work of main frame and other peripheral hardwares outside USB allows, connecting, dispose, use and shift, be i.e. meaning " hot-swappable ".USB can also provide power supply for peripheral hardwares such as digital camera, GPS.
(2) digital camera
Digital camera resolution height, convenient, fast, process software are abundant, can not only gather rest image, and can audio frequency acquiring, video.
The digital camera that the present invention uses need satisfy: a, camera can carry out continuously sampling automatically; B, can carry out high speed communication by USB interface with notebook computer; C, resolution are better than 640*480,24 true color; D, shutter speed be less than 1/128 second, to guarantee in that have slightly under the situation of rocking also can operate as normal; E, support general-purpose industrial standard, or DLL (dynamic link library) is provided.
The e that Aomega company produces claps 3000+ type digital camera and native system requires to match.
