如何计算地图上两个坐标之间的直线上N个等距点的坐标？

// 计算地图上两个坐标之间的直线上N个等距点的坐标
function calculateEquidistantPoints(lat1, lon1, lat2, lon2, N) {
  // 将经纬度转换为直角坐标系
  var x1 = Math.cos(lat1) * Math.cos(lon1);
  var y1 = Math.cos(lat1) * Math.sin(lon1);
  var z1 = Math.sin(lat1);

  var x2 = Math.cos(lat2) * Math.cos(lon2);
  var y2 = Math.cos(lat2) * Math.sin(lon2);
  var z2 = Math.sin(lat2);

  // 计算起点和终点之间的直线距离
  var distance = Math.sqrt(Math.pow(x2 - x1, 2) + Math.pow(y2 - y1, 2) + Math.pow(z2 - z1, 2));

  // 计算等距点之间的距离
  var equidistantDistance = distance / (N + 1);

  // 计算等距点的坐标
  var equidistantPoints = [];
  for (var i = 1; i <= N; i++) {
    var t = i * equidistantDistance / distance;
    var x = x1 + (x2 - x1) * t;
    var y = y1 + (y2 - y1) * t;
    var z = z1 + (z2 - z1) * t;

    // 将直角坐标系的x、y、z坐标转换回经纬度
    var equidistantLat = Math.asin(z);
    var equidistantLon = Math.atan2(y, x);

    equidistantPoints.push({ lat: equidistantLat, lon: equidistantLon });
  }

  return equidistantPoints;
}

// 示例使用
var startPoint = { lat: 40.7128, lon: -74.0060 }; // 纽约市
var endPoint = { lat: 34.0522, lon: -118.2437 }; // 洛杉矶
var N = 5; // 等距点数量

var equidistantPoints = calculateEquidistantPoints(startPoint.lat, startPoint.lon, endPoint.lat, endPoint.lon, N);
console.log(equidistantPoints);
