correlation_flow

Optical flow calculation using image correlation for no_std rust.

Embedded Examples

The examples are currently designed to be used with J-Link / RTT. In the future as tools such as probe-rs solidify, we may switch to that toolset.

• In one shell run: ./start_gdb_server_jlink.sh
• In another shell run: JLinkRTTClient
• Then run your choice of examples

PX4FLOW

This example is intended to run on the PX4FLOW hardware. It simply compares two image frames stored in the app binary.

cargo run --example px4flow --release

Image Conversion

We used ImageMagick's convert command to generate raw 8-bit grayscale images from png files using eg:

convert 64sq_253_46.png -depth 8 64sq_253_46.gray

Status

• Detects discrete 2D image translation within a static 64x64 grid (maximum +/- 32 pixel movement)
• Example that runs on embedded hardware (PX4FLOW)
• Simple test runs (currently tested under std using glovent)
