Read a Single .raw Thermal Image File — read_thermal

Reads a binary .raw file (typically 32-bit floating point), converts it into a matrix, and constructs a 'BioThermR' object containing raw data and metadata.

Usage

read_thermal_raw(file_path, width = 160, height = 120, rotate = TRUE)

Arguments

file_path: String. The full path to the .raw file.
width: Integer. The width of the thermal sensor (number of columns). Default is 160.
height: Integer. The height of the thermal sensor (number of rows). Default is 120.
rotate: Logical. Whether to rotate the image 90 degrees counter-clockwise. Default is TRUE (corrects orientation for many standard sensor exports).

Value

A list object of class "BioThermR" containing:

raw: The original temperature matrix (numeric).
processed: A copy of the raw matrix, intended for subsequent ROI filtering or masking.
meta: A list containing metadata: filename, fullpath, and dims.

Examples

if (FALSE) { # \dontrun{
img <- read_thermal_raw("data/sample.raw")
} # }
