Solved with this piece of code:

// jQuery
wp_enqueue_script('jquery');
// This will enqueue the Media Uploader script
wp_enqueue_media();
?>
    <div>
    <label for="image_url">Image</label>
    <input type="text" name="image_url" id="image_url" class="regular-text">
    <input type="button" name="upload-btn" id="upload-btn" class="button-secondary" value="Upload Image">

</div>
<script type="text/javascript">
jQuery(document).ready(function($){
    $('#upload-btn').click(function(e) {
        e.preventDefault();
        var image = wp.media({ 
            title: 'Upload Image',
            // mutiple: true if you want to upload multiple files at once
            multiple: false
        }).open()
        .on('select', function(e){
            // This will return the selected image from the Media Uploader, the result is an object
            var uploaded_image = image.state().get('selection').first();
            // We convert uploaded_image to a JSON object to make accessing it easier
            // Output to the console uploaded_image
            console.log(uploaded_image);
            var image_url = uploaded_image.toJSON().url;
            // Let's assign the url value to the input field
            $('#image_url').val(image_url);
        });
    });
});
</script>
