Combined camera shooting system, mobile terminal and image processing method

Abstract

The invention discloses a combined camera shooting system, a mobile terminal and an image processing method. According to the combined camera shooting system, a laser projection device is used for projecting a structured light pattern of invisible laser to a shared field of view of a first camera shooting device and the second camera shooting device; the first camera shooting device is used for collecting a first visible light image and a first invisible light image synchronously; the second camera shooting device is used for collecting a second visible light image and a second invisible light image synchronously; and a processor is used for calculating a first depth image through utilization of the first invisible light image, calculating a second depth image through utilization of the second invisible light image, synthesizing the first depth image and the second depth image to obtain a third depth image, and carrying out visual motion tracking through utilization of the second visible light image. According to the system, the mobile terminal and the method, collection of the visible light image, collection of the target depth images and the visual motion tracking can be synthesized, and the depth image with a wider depth range and higher spatial resolution can be synthesized.

Description

[0001] 【Technical field】 [0002] The invention relates to the fields of optical measurement and electronics, in particular to a combined camera system, mobile terminal and image processing method. [0003] 【Background technique】 [0004] RGB images can record the color features of objects, and have been widely used in pattern recognition, such as face recognition and object detection. In recent years, with the development of depth measurement technology, especially based on the development of structured light technology, the use of depth cameras to measure the depth information of objects for further applications such as somatosensory manipulation, 3D reconstruction, tracking and obstacle avoidance has gradually gained attention. [0005] Equipping a computing device with a color camera and a depth camera makes the device have a wider range of functions, but considering mobile devices such as mobile phones, tablets and other small computing devices, it is unwise to set up many...
