Can depth information be droped from the algorithm?

Dear author! I really appreciate your great work! Follow your paper and readme, I reproduced the result of your paper. This technology meets one of our practical application needs. I read your paper and code and found that you used ConditionalNerf to describe the 3D scene using scene depth information, but this requirement will limit the application scope of this technology, such as using a mobile phone to take pictures and localize it (most mobile phones cannot get depth information). I'm wondering if I can waive the condition of using depth information? Can you give some advice? Thank you so much!
尊敬的作者您好！我觉得您做了非常好的成果！在论文和readme的指引下，我复现了您论文的工作，这个技术符合我们一个实际应用需求。我读了您的论文和代码，发现您用ConditionalNerf来描述3d场景过程中用了场景深度信息，但这个要求会限制该项技术的应用范围，例如使用手机拍照定位（绝大多数手机得不到深度信息）。我在想能否放弃使用深度信息的这个条件？您能给一些建议么？非常感谢！
