In some implementations, a system may include a camera, a display, one or more memories, and one or more processors communicatively coupled to the one or more memories. The system may output a guide marker for presentation on the display. The guide marker may be superimposed on an image being captured by the camera and presented on the display. The system may determine three-dimensional (3D) coordinates of an intersection point associated with the guide marker. The intersection point may be a point where a projection of the guide marker into 3D space intersects with a horizontal plane identified in the image. The system may determine two-dimensional (2D) coordinates for presentation of an augmented reality object on the display based on the 3D coordinates of the intersection point. The system may superimpose a representation of the augmented reality object on the image based on the 2D coordinates.
