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.

shell script 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: shell script convert 64sq_253_46.png -depth 8 64sq_253_46.gray

Status

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