Abstract

According to a depth image imaging system and method provided by the invention, a thin film zoom lens is used for imaging, and the focal length of the thin film zoom lens is changed by applying a voltage to a dielectric elastomer of the thin film zoom lens, so that emergent light passing through the thin film zoom lens is focused and defocused on an image sensor to obtain a focused image and a defocused image; at least two different voltages are applied to each shot scene, a focusing image and a defocusing image of the scene are obtained, the depth of the scene is calculated according to the focusing degree and the defocusing degree in the focusing image and the defocusing image, and a depth image is obtained. According to the depth image imaging system and method, the single camera of thethin-film zoom lens is used for achieving depth measurement, distance measurement of an infrared emitter or a laser emitter is not needed, and RGB images and depth images can be output at the same time. In addition, in the depth image imaging system and method, the depth measurement precision is high, the hardware structure is simple, the process complexity is low, the computing power consumptionis small, and the system and method are suitable for multiple scenes.

Description

technical field [0001] This specification relates to the field of image acquisition technology, and in particular to a depth image imaging system and method. Background technique [0002] In recent years, with the continuous development of science and technology, the application scenarios of computer vision have become more and more extensive. At the same time, depth camera technology has attracted more and more attention from the industry. Depth cameras can measure the distance between objects in the scene being photographed and the camera. Obtaining the distance between the object in the scene being shot and the camera brings a lot of room for the development of human-computer interaction technology. With the two-dimensional image in the scene being shot captured by the camera, people can easily get a picture of the surrounding scene. three-dimensional information. Therefore, this type of product has begun to be widely used in many fields such as industrial automation, c...
