Controller 140 is connected with camera array 120 and storage device 130 respectively, is triggered for being sent to camera array 120
Instruction, so that camera array 120 is triggered, and obtains directional information and spectral information from storage device 130, to directional information and
Spectral information is decoupled, and the scene residing for target observation object is rendered according to the depth image for obtaining, to obtain
The spectral information and field information of scene.
Specifically, controller 140 by communication (such as bluetooth) or wired communication mode respectively with camera array
120 are connected with storage device 130, send triggering command with to camera array 120, and obtain direction from storage device 130
Information and spectral information.
In other words, in gatherer process, the light that destination object sends is modulated via each filter, and correspondence is incided respectively
On the camera of each filter, single camera has collected the light information of specific wavelength and specific direction, and wavelength and direction
Information is to intercouple；, by each camera separate storage, after gatherer process terminates, data are via side wirelessly or non-wirelessly for data
Formula is transmitted to backstage (i.e. controller 140), and background program emits beam in the redundancy of spatial domain according to destination object, i.e., different
Correlation between the image of wavelength different directions, carries out joint decoupling, so as to obtain to the light information that each camera is collected
Take light information of the destination object on each wavelength and all directions.Simultaneously because in data acquisition, each camera is
Continuously can gather in real time, what is obtained is one group of video flowing, meets the need to dynamic scene multispectral light-field real time imagery
Ask.The light information of each wavelength of all directions is gathered, each camera internal is not related to the link of light splitting, makes full use of the sensing of camera
Unit is imaged, and the image information for obtaining is spatially possess high-resolution.
Further, in one embodiment of the invention, the multispectral light-field video acquisition device also includes：Display mould
Block, display module be connected with controller 140 and camera array 120 respectively, controller 140 be used for triggered in camera array 120
Before, control camera array 120 carries out preview to target observation object, and shows Preview results by display module, so as to realize
Preview to destination object.In one embodiment of the invention, display module is, for example, mobile terminal, and mobile terminal for example leads to
Cross bluetooth to be in communication with each other with controller 140, so as to realize carrying out preview to destination object in collection money.In other words, i.e., in video
Before collection, can be by wirelessly carrying out live preview to destination object on backstage or mobile terminal.
In order to make it easy to understand, below in conjunction with specific embodiment to the multispectral light-field video acquisition device of the embodiment of the present invention

Row imaging, and record data in storage device.Preview, triggering and collection that background server passes through wireless network control camera
Process, and carry out data transmission；The end processing sequences of data are also completed at background server end.For the direction for intercoupling
Information and spectral information, background server end carry out the Stereo matching across passage according to the redundancy of spatial information, and direction is believed
Breath is decoupled with spectral information, and scene is done according to the depth image for obtaining further renders, so as to obtain the light of scene
Spectrum information and field information.Referring to Fig. 2, filter array is placed in camera array leading portion, and filter is corresponded with camera, filter
Diameter is greater than camera, and filter array and camera array close proximity, it is ensured that the light of incident phase modifier all have passed through filter
Modulation, while preventing the fixed plate of filter array from causing to block to the visual field of camera.
In the present embodiment, for example, filter array and camera array are by taking 3 × 3 scale as an example, the spacing between camera is
10cm, filter array is not more than 0.5cm with the distance of camera array.Further, filter thickness is 1mm, is level crossing, its light
Spectral property is 10 to 20nm bandpass filtering；Furthermore, it is possible to according to the demand of application scenarios, change other spectral patterns
Filter.Further, the parameter that camera is used is 4K30, i.e., 4096 × 2160 spatial resolution and 30 frames time per second divide
Resolution, is easy to the dynamic and high spatial resolution of scene to gather.Further, the framework of wireless network is to add nothing by hub
What gauze card was completed.Hub bus end connects background server, and each interface connects wireless network card respectively, and background server is set
Wireless network card, the wireless signal carried with phase generator terminal is connected, and completes to the synchronous of camera, control and data transfer.By writing
The program of background server, realizes preview, triggering command and the data transfer of camera.Furthermore, it is possible to according to the need of application scenarios
Ask, adjust the parameters such as acquisition frame rate, image resolution ratio and the focusing surface of camera.Background server end, for the side for intercoupling
