In a recent video,[Henrique Ferrolho] demonstrated that this little sensor can also be used to perform a 3D scan of a room. The sensor data can be combined with an IMU to add orientation information to the scan data. These data streams are then combined by an ESP32 MCU that streams the data as JSON to a connected computer.</p>

<p>Of course, that’s just the heavily abbreviated version, with the video covering the many implementation details that crop up when implementing the system, including noise filtering, orientation tracking using the IMU and a variety of plane fitting algorithms to consider.</p>
<p>Note that ST produces a range of these Time-of-Flight sensors that are more basic, such as the <a href="https://www.st.com/en/imaging-and-photonics-solutions/vl53l0x.html" target="_blank">VL53VL0X</a>, which is a simple distance meter limited to 2 meters. The <a href="https://www.st.com/en/imaging-and-photonics-solutions/vl53l5cx.html" target="_blank">VL53L5CX</a> features the multizone array, 4-meter distance range, and 60 Hz sampling sp

Новый инерциальный MEMS-датчик LSM6DSV320X от ST c искусственным интеллектом для распознавания активности и ударов

Инерциальные модули (IMU, Inertial Measurement Unit) выполненные в виде MEMS-датчиков давно используются в смартфонах, игровых контроллерах, носимых устройствах, и т.д. В такой модуль входит акселерометр и гироскоп, вся обработка выполняется на основном процессоре смартфона или микроконтроллера. Для обработки поступающих данных от инерциального модуля, процессор должен быть постоянно в состояние активности. Например, для носимой электроники данный фактор не позволит отправить основной процессор в спящий режим. Вторая проблема заключается в большом лаге между наступлением события и реакции. Например, если необходимо обрабатывать события удара, пока ОС обработает поступающие данные и сделает вывод об ударе, времени на реакцию будет немного. Для решения указанных задач, и не только, компания STMicroelectronics разработала модуль LSM6DSV320X с искусственным интеллектом где вся обработка данных выполняется в самом модуле.

Servus zusammen – heut war wieder so ein Tag, an dem der Kopf einfach zu voll war. Also schnell Jacke drüber, Bike geschnappt und raus an die Donau. 11 Grad, alles bedeckt, dieser graue Himmel wie ein Deckel überm Kopf. Aber genau das mag ich manchmal. Der kalte Wind (so um die neun km/h) hat mir die Gedanken weggeblasen, die Finger aber ziemlich abgekühlt 😅. Nach zehn Minuten war ich wieder daheim – frische Luft reicht oft schon, fei. Daheim hab ich erst mal den […]

Gerade war ich kurz draußen, nur ein kleiner Spaziergang ums Eck – die Luft ist kühl, vielleicht knapp zwölf Grad, und die Wolken hängen tief über der Donau. Es hat so ein leicht graues Licht, das ruhig macht. Ich mag das. Man hört fast nix, außer ab und zu ein leises Surren vom Rad eines Spätheimkehrers. Drinnen dann wieder mein kleines Chaos aus Kabeln und Notizen. Danke nochmal an Michael für die Tipps zu den Referenzen – hab heut beim Durchschauen gemerkt, dass meine […]

Eric Nam's back with a tool to stream inertial measurement unit data over Wi-Fi on an ESP32-S3, then process it for neat visualisations - which play back in real time, but only from a recording not as-it-captures.

I have checked the alignment of the pitot tube with the horizontal axis of the glider's tail boom.

I had to put the glider in a level flight attitude to align the inertial measurement unit in the variometer, and will do it again when I perform the weight and balance analysis.

The first photo shows a small portion of the tail boom, which has a gentle conical profile. Because of that, I had to put a calibrated spacer at one end of the bubble level. (I also double-checked by putting the same setup on the bottom of the tail boom...the boom is now level.)

I took the opportunity to measure the inclination of the pitot tube that is mounted high on the vertical fin. It's well within one degree of level also, which is what I want. (If you keep misalignment under about 15 degrees, the pitot tube should provide accurate indications of total pressure.)

A gray, two-foot long bubble level sits on the white glider tail boom. The right end of the bubble level has a spacer to correct for the conical angle of the tail boom. The left bubble indicator shows the tail boom's axis is horizontal, which is needed for certain measurements and calibrations.

An electronic inclinometer (which was tested against the bubble level) is sitting on the gray aluminum pitot tube that is mounted on the glider's vertical fin. It shows that when the tail boom is horizontal, the pitot tube is as well.

The final instrument has been installed, and it passes basic function tests.

It's a modern glider variometer that has an inertial measuring unit, two GNSS receivers, a three-axis magnetic field sensor, and two air pressure sensors. It can determine the true flight path, in 3D, very precisely, and its response time to changes in air motion is very short.

In this short video, I show that the vario display (small round screen) is sharing data with the glide computer (larger rectangular screen). As I raise the instrument panel, the artificial horizon shows a corresponding change.

Here's a good explanation and demo:
