In this paper, a new geometric structure of projective invariants is proposed.
Compared with the traditional invariant calculation method based on 3D reconstruction, this method is comparable in the reliability of invariant calculation.
According to this method, the only thing needed to find out is the geometric relationship between 3D points and 2D points, and the invariant can be obtained by using a single frame image.
In the method based on 3D reconstruction, the basic matrix of two images is estimated first, and then, the 3D projective invariants are calculated according to the basic matrix.
Therefore, in terms of algorithm complexity, the method proposed in this paper is superior to the traditional method.
In this paper, we also study the projection transformation from a 3D point to a 2D point in space.
According to this relationship, the geometric invariant relationships of other point structures can be easily derived, which have important applications in model-based object recognition.
At the same time, the experimental results show that the eight-point structure invariants proposed in this paper can effectively describe the essential characteristics of the 3D structure of the target, without the influence of view, scaling, lighting, and other link factors, and have good stability and reliability.
