Advanced photo navigation tutorial (automatic batch photos) (half-day tour of Chaoyang Park)

In the last photo navigation tutorial, we talked about how to use flight points and Google Earth for photo navigation. Today we are going to provide an advanced photo navigation tutorial, automatic batch photo navigation using more advanced tools and methods is actually using tools to add longitude and latitude to photos in batches.

First, let's talk about the specific principle: Since we use tools to add longitude and latitude to photos in batches, we must match the latitude and longitude to the photos. Yes, that's right. The track with latitude and longitude is the track we need. We can match the track with the photo and use the software to add the latitude and longitude information in the track to the photo, here, the relationship is time, and the tracks at the same time point match photos at the same time point. Therefore, the key here is to adjust the time to be consistent before you start and take the photo. Of course, some software also has the ability to automatically adjust the time difference for the corresponding function, but I think it is best to match the time to the same, so you can calculate the time difference by yourself. OK. Today we bring our device: One 255 W, one Kodak camera. Now, let's go. The target is Chaoyang Park.

It took me four hours in the afternoon to finish the whole park. It may not be comprehensive, but at least I took a whole lap and got exhausted. Let's see my route, this is all the routes I have traveled. It took 11.3 kilometers in total, with an average speed of 3 kilometers per hour.

Let me talk about the specific operations.

Step 1: retrieve data

Connect the W device to the computer using the USB data cable, wait for the computer to recognize the device flash as a drive, enter the memory drive, and find current in the GPX directory under the Garmin directory. copy the GPX file for backup. In fact, this is all the track files. You can use the mapsource tool to open and view them.

Step 2: Take the photo

We will not talk much about this step. We all know that we will save the photos from the SD card to the hard drive of the computer.

Step 3: Install the tool and match the coordinates, the most critical step.

The tool we want to use today is gpicsync. Although other tools can also be used, such as photomapper and pixgps, it may have powerful functions and simplified Chinese characters, the most important thing is open-source software. Of course, I have never used these software, but it should be relatively simple, so I write while doing it.

First download the software,: http://code.google.com/p/ gpicsync/, then install the software, after opening the software, we can see as shown:

The first one in the top two boxes is the photo folder, and the following is the path of the GPX file. Do not select the following options except the backup photo. In the UTC time difference, enter 8 because the time of the GPX file is UTC time, while the time of my camera is set to Beijing time. Among the options for location difference of photos, the default value is 300 seconds. Because you have aligned the time, there is no big error. From the last point of view, this gap is generally less than one minute, and 300 seconds is relatively loose. Click "Start synchronization". OK, and your photos will start to automatically add coordinates. Wait for a moment, and then prompt to complete. In this case, in addition to adding coordinate information to the photo, the software generates both a thumbnail and a kml file, you only need to open the kml file using Google Earth to view all your photos, as shown in:

Cool, there are two directories, photos and track, under the kml file of Chaoyang Park. Photos is all your photos, and track is the path of your track. It can be seen that the software is so powerful that you can even create online photo sharing. These powerful features will be explained later.

If you are familiar with Google Earth, you can even create a flight view. click the button on the right of the axis at the top of the layer to fly your journey from the ground up, check the photo again. Of course, you can also save this flight record and click it to view it. You can even package the content directly into a kmz file and share it with friends, but the photos should not be too large. I have more than three hundred million photos here, totaling more than 400 mb, after opening the image, it will almost crash. You 'd better process the photo first.

The last thing to note is that the kml files produced by the software are encoded by default, because our systems are all in the Chinese version, so they are generally the Simplified Chinese encoding of the default gb2312, you need to open the kml file and save it as a UTF-8 encoded file. In this way, Google Earth can open a file with Chinese characters without garbled characters.

OK. Now our advanced tutorial on photo navigation is complete. For more advanced features and beautification, let's share it next time. Now you can put these photos into the game 760 for photo navigation. Try it.

========================================================

The half-day tour of Chaoyang Park ended successfully. After processing, I finally uploaded the game to picasaweb. After comparison with Google map and Google Earth, I found that there was still a certain deviation, but the distance was not very large, however, I can clearly feel that the position I stood when taking a photo is about 10 meters away from the position of the photo in Google map. Maybe the time matching is not accurate enough, it should be adjusted, but the whole idea is completely feasible. Next time, it will be a better job. Let's take a look at my 294 photos of Chaoyang Park:

My own album address: http://photo.sharesh.cn/beijing/ChaoyangPark/

Google picasaweb: http://picasaweb.google.com/tangf2004/ZMlLdJ

View my photo in Google map (Please adjust to satellite view): http://picasaweb.google.com/lh/albumMap? Uname = tangf2004 & Aid = 5316202756299254193 # Map

Of course you can also view in Google Earth: http://picasaweb.google.com/data/feed/base/user/tangf2004/albumid/5316202756299254193? Alt = kml & kind = Photo & HL = zh_cn

opening the last 300 images in Google map is also a little slow and memory-consuming. For better compatibility, I finally used real coordinates to mark the photos, because I also brought a 60csx to record the Earth's coordinate trajectory. Finally, the biggest mistake in this photo is to forget to add a watermark, so I don't want to bother it any more. But I have already written copyright and other information in EXIF. Next time, we will continue to talk about photo processing, mainly in small details such as automatic color grading, batch size adjustment, uploading to the album, and EXIF information modification, let me have a free and powerful album system like you. Thank you very much for Google. Haha
