findkey_ts

🇷🇺 Версия на русском

Program to compute Affine/Helmert 2D transformation parameters.

Ported from C to TS by li0ard

ATTENTION: This program is only compatible with Bun

CLI

Usage

findkey_ts --f1 <coord1> --f2 <coord2>

Input files

For the program to work, 2 files are needed: a file with coordinates in the original coordinate system and a file with coordinates in the desired coordinate system (6-7 pairs of coordinates are needed for the best result)

Coordinate pairs are written in the Y X format

API

/** Represents the formatted transformation parameters */
export interface formattedH {
    A0: number,
    A1: number,
    A2: number,
    B0: number,
    B1: number,
    B2: number,
}

/** Represents the transformation parameters with scale (mu), angle (theta), and residuals */
export interface Keys {
    h: formattedH,
    mu: number,
    theta: number,
    residuals: number[][]
}

/**
 * Find parameters
 * @param fp0 Array with coordinates in original CS in the format "Y X"
 * @param fp1 Array with coordinates in desired CS in the format "Y X"
 * @returns 
 */

export const findKey = (fp0: string[], fp1: string[]): Keys => {}

/**
 * Reverse parameters
 * @param h Property `h` of `findKey` function result 
 * @returns 
 */
export const reverseH = (h: formattedH): formattedH => {}
