Feature detection data in raw camera coordinates.

Because these are in raw camera coordinates (and thus have not been undistorted with any lens distortion model), they are called “distorted”.

Note that in .braidz files, subsequent rows on disk are not in general monotonically increasing in frame number.

See the “Details about how data are processed online and saved for later analysis” section in the “3D Tracking in Braid” chapter of the User’s Guide for a description of why these cannot be relied upon in .braidz files to be monotonic.

Fields

camn: CamNum

The number of the camera.

frame: i64

The synchronized frame number.

This is very likely to be different than Self::block_id, the camera’s internal frame number, because Braid synchronizes the frames so that, e.g. “frame 10” occurred at the same instant across all cameras.

timestamp: Option<FlydraFloatTimestampLocal<Triggerbox>>

This is the trigger timestamp (if available).

cam_received_timestamp: FlydraFloatTimestampLocal<HostClock>

Timestamp when the camera received the frame.

device_timestamp: Option<u64>

Timestamp from the camera.

block_id: Option<u64>

Frame number from the camera.

Note that this is not the synchronized frame number, which is Self::frame.

x: f64

The X (horizontal) coordinate of the detection, in camera pixels.

y: f64

The Y (vertical) coordinate of the detection, in camera pixels.

area: f64

The area of the detection, in camera pixels^2.

slope: f64

The slope of the detection.

The orientation, modulo 𝜋, of the detection, is atan(slope).

eccentricity: f64

The eccentricity of the detection.

frame_pt_idx: u8

The index of this particular detection within a given frame.

Multiple detections can occur within a single frame, and each succesive detection will have a higher index.

cur_val: u8

Current pixel value.

mean_val: f64

Mean pixel value.

sumsqf_val: f64

Sum of squares of pixel values.
