![]() ![]() Please note that the Walabot Creater only has one Micro USB port, which is used for both power supply and signal exchange. ![]() In this project, a Micro USB to USB Cable is used to connect the Walabot Creater and Raspberry Pi 4 B. Parts: Walabot Creator, USB Camera, USB cable, Raspberry Pi 4 B Step 1: Connect the Walabot and USB camera to Raspberry Pi 4 Additionally, the coordinates, the distance and the amplitude of the target will be sent to Azure IoT Hub for further use. As soon as the return results are obtained, the identified faces will be marked with green rectangles on the image, which will be uploaded to the Azure Blob Storage for remote access. Once the distance is smaller than the low threshold, or larger than the high threshold, the USB camera will be activated to take the picture and transmit it to the Azure Computer Vision to identify the faces in the image. Hence, the distance between the Walabot and the tracking object can be expressed as the Root Mean Square(RMS)of the distance X, Y and Z. With Walabot SDK for Raspberry Pi, the 3D coordinates of the object can be collected. First of all, the location of the target can be collected continuously by Walabot device, which provides cutting-edge technology for Radio Frequency (RF) tridimensional (3D) sensing and image processing.
