用英语翻译下述文字：论文试验场景过于简单仅基于人工点目标场景为了说明普适性需要增设建筑目标、自然场景等多目标复杂场景验证所提方法。

The experimental scenarios in the paper are too simple, relying only on manually selected target scenes. In order to demonstrate universality, it is necessary to add complex scenarios with multiple targets, such as building targets and natural scenes, to verify the proposed method.
