Upload image to database in laravel 5 using eloquent ORM?

I have one form which contains one file upload.

Form Id is "upload_form"

<input type="file" id="image" name="image"/>

Using javascript onclick function and ajax to pass the image to the controller.

Ajax fn:

$.ajax({
url: 'UploadImage',
data:new FormData($("#upload_form")[0]),
type: "post",
dataType:"JSON",
async:false,

success: function (data) {

console.log(data);

      }
});
}

Routes:

Routes::post('UploadImage','UploadController@Upload');

UploadController:

public function Upload()
{
 //I want to catch the image here and save in temporary file in server 
 //and then want to save the URL in database.
 //Model Name : UserData
 //Column name: ImageUrl

}
