I'm afraid it is impossible to connect multiple UST sensors to 1 pc without using switching hubs.

接続・距離データの連続取得方法を知りたいということですので、 一度urg_libraryのサンプルプログラムで動作を確認していただけますでしょうか。 "urg_library"フォルダの、\current\vs2017\cppにある "urg_cpp.sln"をvs2019で開くと、「プロジェクトの再ターゲット」 という画面が表示されますので、 Windows SDK→10.0 プラットフォーム ツールセット→v142 に設定してOKを押してください。 get_distanceというプロジェクトで接続と距離データ連続取得を行っていますので、 このプロジェクトをビルド・実行して確認してください。 以下のページにライブラリの説明が記載されていますので、参考にしてください。 http://urgnetwork.sourceforge.net/html_ja/library_sample_page.html

確認ですが、変数"i"はどこかで宣言されていますか？ i スポット目の距離が300mm以下のときにコンソールに「近い」と出力したいということでしょうか。
-
センサから出力された距離データを加工する方法であれば、指定の距離値でフィルタリングすることで最大距離を短くすることができます。(if~elseで実装できると思います。) センサ本体を調整して最大距離を短くする、という話であれば残念ながらURG Libraryでは対応していません。

I think you have a hardware related problem. Please contact your nearest distributor or the support team with your details to info@hokuyo-aut.jp.
-
This sensor cannot recognize the objects moving too fast because of the specification of scan period(25ms). I'm afraid I can only advise you to reduce the speed of objects.
-
How about moving the objects closer to the sensor, if possible? The farther you move the object from the sensor, the less you can recognize small objects. For examlple, if the distance between UST-10LX and the object is 10m, the sensor may be unable to recognize the object whose length is less than about 43mm.
-
I want to know if the sensor is recognized by PC. You can check if you visit this page:https://sourceforge.net/p/urgnetwork/wiki/serial_en/ If the sensor is not recognized, and your PC is Windows OS, please try to do below. https://sourceforge.net/p/urgnetwork/wiki/driver_en/ (Win 7/8) https://sourceforge.net/p/urgnetwork/wiki/driver_win10_en/ (Win 10)

If you solve this probrem UST-20LX , how about Storing distance data of several scans and choosing one distance (by median, most frequent, shortest and so on) from stored data？ Storing several scans may weaken the influence of vibration. If you use other sensor, I recommend 3D sensor (YVT-35LX in HOKUYO). Good day!
-
It is very difficult to solve this probrem only one 2D sensor such as UST-10LX because the sensor has no information of its position. One of the solutions may be using 3D sensors , I think.
-
If you can get the error code from the sensor, could you tell it to us ? And We don't recommend that you use UST-10LX outdoors. I'm afiraid that this sensor is for indoor environment.
-
Sorry for late responce. Before ver 2.23 of UST-10LX, data might be missed or incomplete on systems under heavy processing load. please check the sensor firmware version and try to update,if it is old. You can get the software for update from our website(https://www.hokuyo-aut.jp/). If the sensor is newer than ver 2.23, please try to include this sentence at the heading of loop . urg.start_measurement(Urg_driver::Distance,1, 0); If these methods do not work well, if possible, could you send me the...
-
Urg.start_measurement equals to start scanning and storing distance data into buffer. "-1" means endless storing until urg.stop_measurement processes. And urg.get_distance gets 1 scan distance data from buffer. If the interval between 2 get_distance processes is longer than the scanning time( in the case of UTM-30LX-EW：25ms), the buffer can became overflowed and "no response" error can occur.
-
urg.what() method returns the error status of string. Please add it after processing urg_get_distance() like: for (int i = 0; i < 10; ++i) { if (!urg.get_distance(range_data, &time_stamp) || time_stamp == 0) { cout << "no" << endl; cout << urg.what() <<endl; } else { cout << "yes" << endl; } } and tell me what urg.what() returns.

Hi. There is library at this page→ https://sourceforge.net/projects/urgnetwork/files/urg_library/ Please download urg_library-1.2.3.zip. This file includes libs and examples to get various data such as distance. And usage of this library is here→ http://urgnetwork.sourceforge.net/html/ I hope this helps.

センサを認識しない問題が解決したようですので、こちらの質問に回答します。 UG01とUG02の違いも教えていただけたらと思います。 UG02はセンサにノイズ対策（EMC対策）を施したセンサで、UG01よりノイズの影響を受けにくくなっています。

Dear Sonny, We released ver 1.2.2 today in which the bug above has been fixed. Please try to use it!
-
Dear Sonny, You're completedly right and it's my fault caused in updating to ver 1.2.1. I changed the formula (to get the value of radian) to consider "grouping step" value. However, I missed the case when this value is "0". So in this case, the function urg.index2rad(i) always returns the same value regardless of the value of "i". Thank you for informing me that and I'll fix this bug as soon as possible. Regards.

Hi, I contributed to update to ver 1.2.1, and I apologize for not updating Releasenotes. This update has two point like that, 1. fixed bags on angle calculating function (calculating incorrectly when using grouping) 2. fixed bags on function that informs you whether the sensor is stable or not I'll be updating Releasenotes soon. And if you don't mind, please tell us about your trouble. Best.

Dear alidaf, What does intensity mean? Intensity means measurement of laser power received. It isn't clear what these samples are intended to do from the titles but there isn't an explanation that I can find. "Get_distance_intensity" means measuring both distance and intensity from "single" echo. whereas "get_multiecho" means measuring distance with multiecho mode, and "get_multiecho_intensity" means measuring distance and intetnsity with multiecho mode. "Multiecho" means measuring data(distance...
