comment An example homography matrix than shows after transformation, the point inside the triangle could be outside
Wait, I just realize that if I try to convert the transformed point back to 2D. should I multiply the λ? If I need to, then the transformed point is still inside the triangle. Please justify. Thanks

Thanks first, and now I know where is my problem, I don't have the λi. I understand the overall ideas, but why we must have the λi to solve the H?

@MårtenW yes, just a homography that takes a point inside the triangle to outside, no restriction.
