xStr = "fused_object"; yStr = "sensor_object";改为接收到的目标类型

您可以将代码中的字符串变量`xStr`和`yStr`改为接收到的目标类型。具体来说，可以将这两个字符串变量作为函数的参数，然后在调用函数时传入目标类型。修改后的代码可能如下所示：

float TrackObjectDistance::ComputeCameraCamera(const SensorObjectConstPtr& fused_object,
                                                const SensorObjectPtr& sensor_object,
                                                int range,
                                                const std::string& xStr,
                                                const std::string& yStr) {
  double center_distance =
      (sensor_object->GetBaseObject()->center -
       fused_object->GetBaseObject()->center)
          .head(2)
          .norm();
  if (center_distance > s_camera2camera_association_center_dist_threshold_) {
    ADEBUG << "center distance exceed camera2camera tight threshold: "
           << "center_dist@" << center_distance << ", "
           << "tight_threh@"
           << s_camera2camera_association_center_dist_threshold_;
    return (std::numeric_limits<float>::max)();
  }
  float distance = ComputePolygonDistance(fused_object, sensor_object, range);
  AINFO << "Compute " << xStr << "-" << yStr << " distance: " << distance;
  return distance;
}

在这个修改后的代码中，`xStr`和`yStr`分别表示两个目标的类型，它们被作为函数的参数传递，并在输出日志中使用。这样，您在调用函数时可以根据需要传入相应的目标类型，从而实现更加灵活的调用。
