With the popularity of 3D movie animation, 3D technology has also gained increasing popularity among consumers. With the development of digital camera technology today, 3D technology has also become a way of shooting for cameras, giving rise to 3D digital cameras.
3D camera structure:
The 3D digital camera is equipped with two lenses. When we look at objects with our eyes, we capture them from slightly different angles on both sides. For this reason, the images on the left and right are subtly different. After synthesizing these two images in the brain, we can grasp the outline of the object in three dimensions. Therefore, theoretically speaking, installing two lenses on the left and right of a camera can reproduce a stereoscopic image. However, the existing camera technology cannot achieve functions close to those of the human eye. For example, even if both the left and right shutters are opened and closed at the same time, there will be a slight time deviation, causing a deviation in the left and right images.
This time, the newly developed portrait processor "Realistic Photography Engine 3D" was used in the new system and successfully controlled this deviation within 0.001 seconds. This processor also has the function of adjusting the focus, brightness, color, and other left and right portrait photography conditions to be almost the same. Previous techniques have made it difficult to correctly intersect the centerlines of the left and right lenses near the object being photographed. The new system overcomes this difficulty by using a newly developed 'real 3D lens system'.
Working Principle:
To uncover the principles of 3D imaging, we need to simplify them very simply. We can do an experiment: hold a pen or chopsticks in both hands at the same time, close one eye, use only the other eye, and try to align the tips of the pen or chopsticks in both hands together. You will find that completing this action is more difficult than you imagine. One eye sees an object as a two-dimensional image, and using visual cues such as size and overlap provided by the object, it can determine the order in which these objects are arranged in front of the background, but it cannot know how far apart they are from each other. Fortunately, the human visual system is based on two eyes. When the two horizontally arranged eyes look at the same object, they may see slightly different images due to their slightly different angles, which is called parallax. The brain combines these two images together and automatically analyzes them to form a deep visual perception. At the same time, the brain can also determine the depth and distance of an object based on the magnitude of the positional difference between the same object in the two received images. The farther it is from the eyes, the smaller the positional difference, and vice versa. This is the basic principle of 3D imaging.
