您可以使用 Flask-SocketIO 扩展来实现实时发送输出信息到前端。首先，您需要安装 Flask-SocketIO 扩展:

pip install flask-socketio

然后，您可以使用以下代码来实现实时发送输出信息到前端:

from flask_socketio import emit
from subprocess import Popen, PIPE
from threading import Thread

@app.route('/restruct', methods=['POST'])
def restruct():
    dch = request.form['dch']
    dch_folder = "restr" + dch
    count = 1
    while os.path.exists(os.path.join('D:\\cj', dch_folder)):
        dch_folder = "restr" + dch + "_" + str(count)
        count += 1
    os.makedirs(os.path.join('D:\\cj', dch_folder, 'photos'))
    os.makedirs(os.path.join('D:\\cj', dch_folder, 'kmls'))
    os.makedirs(os.path.join('D:\\cj', dch_folder, 'project'))

    photos_folder = os.path.join('D:\\cj', dch_folder, 'photos')
    kmls_folder = os.path.join('D:\\cj', dch_folder, 'kmls')
    project_folder = os.path.join('D:\\cj', dch_folder, 'project')

    for file in request.files.getlist('files'):
        filename = file.filename
        file.save(os.path.join(photos_folder, filename))

    dhs = request.form.getlist('dh')
    for dh in dhs:
        src_path = os.path.join(r'D:/911kml/', dh + '.xlsx.kml')
        dst_path = os.path.join(r'D:/cj', dch_folder, 'kmls/', dh + '.xlsx.kml')
        shutil.copy(src_path, dst_path)

    # 使用 Popen 执行命令，并将输出信息实时发送给前端
    process = Popen(["python", "restruct.py", dch, photos_folder, project_folder, kmls_folder], stdout=PIPE, stderr=PIPE)

    def send_output():
        while True:
            output = process.stdout.readline().decode().strip()
            if output:
                emit('output', {'data': output})
            else:
                break

    thread = Thread(target=send_output)
    thread.start()

    return 'success'

在上面的代码中，我们使用 `Popen` 执行命令，并将其的标准输出（stdout）实时发送给前端。为了避免阻塞 Flask 应用程序的主线程，我们在一个新的线程中执行 `send_output` 函数来实现实时发送输出信息到前端。同时，在前端页面中，您需要使用 SocketIO 来接收输出信息并将其显示在页面上:

<script src="//cdnjs.cloudflare.com/ajax/libs/socket.io/2.2.0/socket.io.js"></script>
<script type="text/javascript">
    var socket = io.connect('http://' + document.domain + ':' + location.port);

    socket.on('connect', function() {
        console.log('Socket connected');
    });

    socket.on('output', function(data) {
        console.log(data);
        // 将输出信息添加到页面上
        $('#output').append('<p>' + data.data + '</p>');
    });
</script>

在上面的代码中，我们使用 SocketIO 连接 Flask 应用程序，并在接收到实时输出信息时，将其添加到页面上。请注意，在上面的代码中，我们使用了 jQuery 库来操作 DOM 元素。如果您不想使用 jQuery，您可以使用纯 JavaScript 来实现相同的效果。
