fontbots proposed the following answer:
Detecting an image of a 3D model from various angles and zoom levels can
be a challenging task, but there are a few approaches you can consider.
Here are a couple of suggestions:

Feature Detection and Matching: You can use feature detection algorithms
like Scale-Invariant Feature Transform (SIFT) or Speeded-Up Robust
Features (SURF) to extract distinctive features from both the 3D model
and the image. Then, you can match these features to find
correspondences between the model and the image. By analyzing the
correspondences, you can estimate the rotation and scale of the 3D model
in the image.

3D Model Rendering and Comparison: Instead of directly matching
features, you can render the 3D model from different viewpoints using
computer graphics techniques. Then, compare the rendered images with the
target image using methods like normalized cross-correlation or
structural similarity index (SSIM). By finding the best match or highest
similarity score, you can estimate the rotation and scale of the 3D
model in the image.

Both approaches require some computational resources and may involve
complex algorithms. OpenCV, a popular computer vision library, provides
implementations of feature detection algorithms and image matching
techniques that you can leverage for your task.

It's worth noting that these suggestions provide a starting point, but
depending on the specific requirements and constraints of your
application, additional techniques or refinements may be necessary.
Experimentation and fine-tuning will likely be required to achieve
accurate and robust results.also visit  https://fontbots.com/
