Description of the invention: [Technical field to which the invention pertains] The present invention relates to a method and apparatus for investigating traffic network information, and more particularly to a simple, accurate and complete method and apparatus for investigating traffic network information. [Prior Art] » In recent years, due to the removal of Global Positioning System (GPS)'s Selective Availability (SA), GPS-enabled products have sprung up. Among them, the navigation system is the most widely used. The industry uses GPS positioning function, combined with electronic maps and various traffic network information to provide users with better route planning and navigation. However, urban plans have changed, road construction has continued, and changes in shops and service agencies have been rapid, resulting in changes in traffic network information. Once the navigation system is completed, the manpower and material resources of the subsequent road network information update are not countable. In the past, when vendors conducted road network information surveys, they had to hire a large amount of manpower to investigate notes, or take photos and archive them along the map. If you have problems with length, width, etc., such as lane width, line length, etc., you need to use the gauge wheel tool as shown in Figure 1. As shown in the figure, when the length is to be measured, the grip 12 of the distance measuring wheel 10 is hand-held, so that the roller 14 is rolled at the position to be measured, and the internal gear of the measuring device 16 is driven by the roller 14, and the roller can be driven. The distance traveled by 14 is counted and displayed. 2 201028648 Although this form of survey method can achieve the purpose of updating road information, every survey is a laborer's move. Once there is any omission, it is necessary to send a staff to the site for investigation again. The time and manpower and material resources are extremely depleted. SUMMARY OF THE INVENTION The main object of the present invention is to provide a method and device for investigating traffic network information, and more particularly to a simple, accurate and complete survey method and device for traffic network information. Φ A secondary object of the present invention is to provide a survey device for traffic road network information, which mainly uses a motor vehicle to load a differential global positioning system, a digital camera and a computer, and can combine photos of various road conditions and coordinates. Another object of the present invention is to provide a traffic network information surveying device, which can also be provided with a digital video recorder for dynamic video recording of road conditions. Another object of the present invention is to provide a method for investigating traffic network information. The digital camera is capable of photographing road conditions with a fixed height, a direction, a pitch angle, and a focal length, and can unify the view of each road photo. Another object of the present invention is to provide a method for investigating traffic network information, which mainly comprises a measurement matrix, which can measure the length and width of the road condition photo. Another object of the present invention is to provide a method for investigating traffic network information so that each road condition photo has an appropriate amount of overlap to prevent loss of road information. In order to achieve the above object, the present invention provides a traffic network information adjustment 3 201028648 inspection device, which mainly comprises: a motor vehicle for loading required equipment; and a differential satellite receiver disposed on the motor vehicle. For receiving a differential global positioning system signal; a digital camera mounted in the motor vehicle; and a computer disposed in the motor vehicle, respectively connected to the differential satellite receiver and the digital camera, according to the differential global positioning system signal Positioning to obtain coordinates and record the track, the digital camera can be controlled to take a picture of the road condition, and the road condition photo is stored. The invention further provides a survey method for traffic road network information, which mainly comprises the following steps: planning a survey route; providing a survey device comprising a motor vehicle, a differential satellite receiver, a digital camera and a computer; Device; take a picture of the road condition according to the planned survey route; combine the photos of each road condition with the corresponding coordinates; and read the road information of each road photo. [Embodiment] First, please refer to Fig. 2, which is a configuration diagram of a survey device according to a preferred embodiment of the present invention. • As shown, the traffic network information surveying apparatus of the present invention mainly includes a motor vehicle 22, a digital camera 24, a differential global positioning system (DGPS) antenna 26, and a computer 28. Among them, the motor vehicle 22 is used to load various equipment and is convenient to travel on the road for investigation. A differential satellite receiver 26 is mounted on the motor vehicle 22 for receiving differential global positioning system signals and transmitting signals to the computer 28 for precise positioning operations. The digital camera 24 is mounted in the motorized 201028648 vehicle 22, particularly in the position of the assistant's seat, connected to the computer 28 and controlled by the computer 28 for taking photos of the road condition. Since the road condition photographed by the digital camera 24 of the present invention needs to have the function of road measurement, the digital camera 24 should be mounted with a fixed height h, a fixed direction d, and a fixed pitch angle a with respect to the motor vehicle 22. The fixed swing angle w, and the focal length of the digital camera 24 lens should also be fixed. When the computer 28 controls the digital camera 24 to take a picture of the road condition, the road condition is transmitted to the computer 28 for archiving. The photos of each road condition can be combined with the corresponding coordinates obtained by the differential global positioning system, for example, the corresponding coordinates are written into the Exchangeable Image Format (EXIF) data table of the road condition photo, or the road condition photo is corresponding thereto. The coordinates are stored in the database. When taking a photo of the road condition, the computer 28 controls the digital camera 24 to take a road photo shot at a fixed time interval of 0.5 seconds to 2 seconds, while the motor vehicle 22 travels at a speed of 15 km to 30 km per hour, which is better. The photos of the adjacent roads have appropriate overlapping parts, which can prevent road information from being missed in subsequent operations and can repeatedly confirm relevant road information. The survey device of the present invention may further comprise a digital video recorder 29, which can be used to record the entire survey route for post-mortem monitoring and verification. To take into account the space configuration and the suspension effect, the computer 28 of the survey device can be implemented using a notebook computer. Referring to Figure 3, a flow chart of a survey method in accordance with a preferred embodiment of the present invention is shown. 5 201028648 The survey party of the traffic road network information of the present invention 301: planning, route. Because of the traffic formed by the national roads: the network is complex, even if only partial investigations are carried out, there are still some: roads, secondary roads, branch lines, lanes, even unnamed passages, = lanes, etc. Therefore, regardless of the size of the survey, the route must be investigated first to avoid repeated investigations or omissions. When planning the survey route, Figure 40 as shown in Figure 4 can be created in advance. It is mainly a paper map. In principle, a map with a scale of 5,000 to 10,000 is preferred, and the scale can be adjusted according to the road density of the survey area. The section of the survey route and the survey line can be planned on King's bottom plan 4() in order to complete the survey quickly and completely. - Next step 303: Correct the survey device. The survey device used in the present invention is mainly a survey device as shown in Fig. 1, and mainly includes a camera & vehicle 22 digital camera 24, a differential satellite receiver %, and a computer 28. In order to save manpower configuration, ensure survey integrity and road information measurement, the erection of the digital camera 24 should be responsive to the motor vehicle 阿 阿 阿 、, fixed direction d, fixed pitch angle & The fixed swing angle w, and the focal length of the digital camera 24 lens should also be fixed. In addition, in order to measure road information, a matrix 52 can be constructed as shown in FIG. The measurement matrix 52 is a matrix of a wide and flat depression, which is green according to the size of the demand. The distance between the vertical line 52\ of the measurement matrix 52 and the vertical line 521 is preferably 0.5 meters, and the distance between the horizontal line 523 and the horizontal line 523 is preferably i meters. After the measurement matrix 52 is completed, the digital camera 201028648 24 using the survey device is used to perform corrective shooting with high calibration conditions.祀摅 θ, | angles and focal lengths of the measurement matrix Α 仕 仕 摄 仕 仕 仕 仕 仕 仕 仕 仕 仕 仕 仕 仕 仕 仕 仕 仕 仕 仕 仕 仕 仕 仕 仕 仕 仕 仕 仕 仕 仕 仕 仕 仕 仕 仕 仕 仕 仕 仕 仕Seeing the situation is forbearing ^.. "The photo of the road taken by the cow is compared and measured for filial piety. Μ and differential global - fixed inclusion will be mathematical. The step can be used to facilitate the follow-up work. The road is taken according to the planned survey route. Complete the adjustment of the road =::=rr, you can go on the road according to the planning investigation brother..., film shooting. Due to the use of motor vehicles 2 = the survey is no different from the normal driving situation, there is no need for special system, and there will be no traffic obstruction caused by the investigation. The shooting time interval for taking photo photos of the road is 〇 5 seconds to 2 seconds. ^ Better' with the driving speed between 15 km/h and the deduction km is the parent ^. The adjacent road conditions photos can be appropriately overlapped to ensure complete shooting of the road conditions and mutual verification. _. Due to the complexity of the road network and the wide range of information, the number of road photos is extremely large. Therefore, photographs of road conditions should be better carried out in sections, which can also facilitate the management of road conditions photos and materials. The shooting of each segment should have a complete record, including the shooting date, the photographer, the shooting section, the starting point, the turning point, and so on. If it is the efficiency of the statistical or analytical investigation, the starting mileage, the ending mileage, the total mileage, the starting gate, the 'α bundle time and the total time can be recorded together. The shooting record is planned as shown in Figure 6. In addition, it is still possible to take one or several shots of the shooting record table 7 201028648 before the start of each segment. It can form a segmentation in a large number of road photos. Step 307 is: combining the photos of the road conditions with the corresponding coordinates. As the motor vehicle 22 travels to take a picture of the road condition, the differential satellite receiver simultaneously receives the differential global positioning system signal and performs a precise positioning operation with the computer 28 to obtain the coordinates of the location of the motor vehicle 22, and simultaneously record the traveling trajectory. After the photo of each road condition is completed, it can be combined with the coordinates of the road photo. The combination method can store the road condition photo and the corresponding coordinates as the same data in the database, and can also write the corresponding coordinates into the Exchangeable Image Format (EXIF) data table of each road photo. The corresponding photos of the road conditions and the coordinates can be used to find the coordinates of the same time in the travel trajectory according to the shooting time of each road photo. Step 309 is: reading road information of each road condition photo. Photographs of road conditions After the completion of the field shooting, it is necessary to read the required road information from a large number of road photos. The investigation of the entire traffic network information is completed. Due to the investigation method of the present invention, the calibration device has been calibrated before the road condition photo shooting, and the measurement matrix is built, so that rich information can be read from the road condition photo. Please refer to FIG. 5, which is a schematic diagram of a measurement matrix application of the present invention. As shown in the figure, in a road photo 50, a pre-established measurement matrix 52 photo can be nested on the road photo 50. Since the distance between each vertical line 521 and each horizontal line 523 of the measurement matrix 52 is known, when it is overlaid on the road photo 50, that is, the distribution of the objects on the measurement turn 52 on 201028648 50 is a luxury case. The towel is divided into a limit line (double yellow solid line) 541 to the road side line (white solid line) 543 with about 8 vertical lines 521 spacing, so the width of the lane is = Χ 8 = 4 meters. The length of roadside parking spaces is about 5.2. (2) Pitch, width is about (1). 3 vertical and line 521_ giant, (4) The length is about 5.2 Χ 5.2 meters, and the width is about 43 χ〇 5 = 2 ΐ 5 meters. In this way, multiple measurement tasks can be completed quickly. Please refer to Fig. 7 and Fig. 8 for a schematic view of a road condition photo and a road information@@. As shown in the figure, a lot of road information can be read in the road photo 70, such as the location and information of various labels, markings, signs, road names, street lights, manholes and landmarks. It can be seen from the road condition photograph 70 that the road 72 has two lanes in two directions, and is separated by a direction dividing line (double yellow solid line) 727. There are two lanes in the forward direction, separated by double solid white lines 721 and no lane change is allowed. right
