Multi-dimensional camera shooting device, application terminal and method thereof

Abstract

The invention provides a multi-dimensional camera shooting device, an application terminal and a method thereof. The application method of the application terminal comprises the steps: obtaining the two-dimensional image information of a target scene; using at least one dimension-increasing camera shooting unit to obtain dimension-increasing information of the target scene, wherein the dimension-increasing camera shooting unit is provided with a dodging element of a random regularization micro lens array to modulate light beams emitted by a multi-dimensional camera shooting device, and a uniform light field is formed within the needed field angle range so as to illuminate the target scene; and the micro lens array is used for avoiding interference of the light beams in a propagation process, and the micro lens array is formed by a group of micro-lens units in areas with the same shape and size through a random regularization design method so that the micro-lens units are arranged in anaperiodic regularization manner; and obtaining multi-dimensional image information of the target scene based on the two-dimensional image information and the dimension-increasing information.

Description

Technical field[0001]The present invention relates to the field of imaging, and further relates to a multi-dimensional imaging device and its application terminal and method.Background technique[0002]With the development of technology, smart devices have gradually penetrated into all walks of life, such as smart homes, smart robots, face recognition systems, or self-driving cars. As a kind of image sensor of intelligent equipment, the camera is regarded as the "eye of machine vision", which is used to identify the object information of the target scene. For example, camera devices based on TOF (Time of Flight) technology are gradually being used in depth cameras, mobile phones, computers, cameras, autonomous vehicles, smart robots, smart homes, and face recognition, among which the camera device uses TOF sensors to capture images The depth information of the target scene, and then obtain the three-dimensional image of the target object.[0003]In the current market, a homogenizing ele...

AI Technical Summary

Problems solved by technology

[0003] In the current market, a light diffusing element (Diffuser) based on the principle of light diffraction is used to modulate the laser beam emitted by the laser emitter of the camera device to illuminate the captured target scene. The element has zero order, which obviously leads to low energy uniformity, or the low diffraction efficiency of the uniform light element, resulting in low transmittance and other shortcomings, which is not conducive to the collection of information by the camera device

Due to the high coherence of the laser beam, the existing dodging element adopts a regular microlens array structure, in which the microlens array of the dodging element is arranged regularly and orderly in the row and column directions Therefore, the laser beam emitted by the laser emitter passes through the microlens array of the homogenizing element, and interference phenomenon will occur during the space propagation, and then a light and dark fringe pattern will be formed in the target scene, seriously weakening the homogenization. The homogenization effect of the light element is not conducive to the acquisition of depth information by the camera device, resulting in poor image quality, which in turn causes the smart device to be unable to accurately and reliably identify the object information of the target scene, due to unidentified or incorrectly identified The frequency of issuing wrong commands is high, which not only affects the use of users, but also may lead to dangerous accidents, such as traffic accidents in self-driving cars, etc.
