Seems to work well and fast, but was hard to tell how accurate it is because the camera moves too fast. How does it cast the ray, from the centre of the object or from the outer most edges of the object?
With small objects like this its hard to say how effective this method could be when larger objects are on the terrain. But maybe if u checked the points of a bounding box of each object it would still be really fast. I think you'd only need to check the 4 upper corners of each bounding box which isn't too bad.
