depth does not work in Text & RGBD-to-Trajectory generation?

Hi, @kszpxxzmc, in the Text & RGBD-to-Trajectory generation (official example), the depth value does not affect the final generated trajectory. For example, multiply the value of depth by 10, but it seems that the length and scale of the generated trajectory does not change significantly. I'm not sure if I got any mistake, here is my running log：[log.txt](https://github.com/user-attachments/files/23251821/log.txt)

Reproduce the Text & RGBD-to-Trajectory generation official example using the attached log.txt, first comparing the normal depth value with one multiplied by 10. Trace where depth enters trajectory generation and determine whether the resulting trajectory length and scale should change; done means the behavior is explained and, if it is a bug, covered by a reproducible fix and test.
