Maker builds LEGO-cased RGB-D device with real-time point cloud display

A maker (Reddit user No_Quail6685) put a 320×240 iToF sensor, a Pi camera and a Pi Zero 2 W into a LEGO case, with a 240×240 TFT screen on the back, achieving real-time display of a color point cloud. They say that after switching the camera to MJPEG and raising the TFT's SPI frequency from 4 MHz to 32 MHz, the screen displays the point cloud at 15 fps. The device still relies on Wi-Fi: depth and RGB data are sent to a Mac for fusion and rendering, and the rendered image is sent back to the Pi. They say that at a signal of about −73 dBm, 2–4 second stalls occur. The next step is to move rendering onto the device locally, and only after that consider installing it into their robot concept Heron; Heron has not yet been built.
