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 random regularization micro-lens array and used for avoiding interference of light beams in the propagation process so as to improve a light uniformizing effect; 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, an application terminal and a method thereof. Background technique [0002] In recent years, camera devices based on TOF (Time of Flight technology) have been gradually applied to fields such as depth cameras, mobile phones, computers, video cameras, self-driving vehicles, intelligent robots, smart homes, and face recognition. The imaging device has a TOF sensor, wherein the imaging device emits modulated near-infrared light or light pulses through a laser transmitter such as VCSEL, which is reflected after encountering an object, and the reflected light is received by the near-infrared receiving end, wherein the TOF sensor calculates the light emission The distance between the object and the camera device can be obtained from the time difference or phase difference with the reflection, so as to obtain depth information for shooting to obta...

Problems solved by technology

[0003] At present, a light diffusing element (Diffuser) based on the principle of light diffraction is used to modulate the light beam emitted by the laser emitter of the camera device to illuminate the captured target scene, but the existing light diffusing element has zero Level, which obviously leads to low energy uniformity, or 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

Further, the existing dodging element adopts a regular microlens array structure, wherein the microlens array of the dodging element is arranged in a periodic, regular and orderly manner in the direction of rows and columns, so that the laser emitter emits The coherent light beam passing through the microlens array of the uniform light element will produce interference phenomenon in the process of spatial propagation, and then form a light and dark fringe pattern in the target scene, which seriously weakens the uniform light effect of the light uniform element, which is not conducive to The collection of depth information by the camera device leads to poor image quality and poor use effect
