以下是使用OpenCV库的C++代码实现多目标轴两端点定位：

#include <opencv2/opencv.hpp>
#include <iostream>

using namespace cv;
using namespace std;

int main()
{
    int startf = 353, endf = 1500;
    Mat Ibj = imread("Ibj.png", IMREAD_GRAYSCALE);

    for (int i = startf; i <= endf; i++)
    {
        Mat I1 = imread("image" + to_string(i) + ".png");
        Mat gray;
        cvtColor(I1, gray, COLOR_BGR2GRAY);

        gray.convertTo(gray, CV_64F);
        gray -= Ibj;

        Mat bw1;
        threshold(gray, bw1, 25, 255, THRESH_BINARY);

        Mat bwAreaOpenBW;
        morphologyEx(bw1, bwAreaOpenBW, MORPH_OPEN, getStructuringElement(MORPH_RECT, Size(3, 3)));

        Mat labels;
        int n = connectedComponents(bwAreaOpenBW, labels, 8, CV_16U);

        for (int j = 1; j < n; j++)
        {
            Mat mask = labels == j;
            vector<Point> points;
            findNonZero(mask, points);

            Mat X(points.size(), 2, CV_64F);
            for (int k = 0; k < points.size(); k++)
            {
                X.at<double>(k, 0) = points[k].x;
                X.at<double>(k, 1) = points[k].y;
            }

            Mat Y(points.size(), 1, CV_64F);
            for (int k = 0; k < points.size(); k++)
            {
                Y.at<double>(k, 0) = points[k].y;
            }

            Mat coef;
            solve(X, Y, coef, DECOMP_SVD);

            double b1 = coef.at<double>(0, 0);
            double b2 = coef.at<double>(1, 0);

            double minzhi = points[0].x;
            double maxzhi = points[0].x;

            for (int k = 1; k < points.size(); k++)
            {
                if (points[k].x < minzhi)
                {
                    minzhi = points[k].x;
                }
                if (points[k].x > maxzhi)
                {
                    maxzhi = points[k].x;
                }
            }

            double duan1x = b1 + b2 * minzhi;
            double duan1y = minzhi;
            double duan2x = b1 + b2 * maxzhi;
            double duan2y = maxzhi;

            circle(I1, Point(duan1y, duan1x), 3, Scalar(0, 0, 255), -1);
            circle(I1, Point(duan2y, duan2x), 3, Scalar(0, 0, 255), -1);
        }

        imshow("result", I1);
        waitKey(1);
    }

    return 0;
}

其中，`Ibj.png`是背景图像，`imageXXX.png`是目标图像（XXX为帧序号）。代码使用了OpenCV的基本函数来实现图像的读取、灰度化、二值化、形态学操作、连通组件分析、直线拟合等操作。最后，通过绘制圆点来表示两个端点的位置。
