2d-transformation-solver
一个小节点模块,用于从两个公共点列表(不同坐标系)中估计变换参数
Installation
npm install 2d-transformation-solver --save
Usage
var trafoSolver= require('2d-transformation-solver');
//input
var pointSet = {
'start':[
{'x': 1.0, 'y': 2.0},
{'x': 3.0, 'y': 7.0}
],
'target':[
{'x': 2.0, 'y': 3.0},
{'x': 4.0, 'y': 8.0}
]
};
//calculate transformation parameter
var resultSet = trafoSolver.estimate2DTrafo(pointSet);
console.log(resultSet);
/*var resultSet = {
'tx': 1.0,
'ty': 1.0,
'scale': 0.9999999999999991,
'rotation': -4.44089209850063e-16,
'stdDev': 7.444291678311382e-15
}*/

2d-transformation-solver
a small node modul to estimate the transformation parameter from two list of common points (different coordinate systems)
