Abstract

The embodiment of the invention provides a TOF system, an image processing method, and a storage medium. The TOF system comprises: multiple band receiving modules, wherein the multiple band receiving modules comprise multiple optical filters corresponding to multiple bands; multiple band transmitting modules corresponding to the multiple band receiving modules, wherein the transmitting module of one band in the multiple band transmitting modules corresponds to the receiving module of one band; and a controller connected with the multiple band transmitting modules and the multiple band receiving modules; wherein the controller is used for determining a current scene and a first band corresponding to the current scene; determining a first band transmitting module and a first band receiving module from the multiple band transmitting modules and the multiple band receiving modules according to the first band; the first band transmitting module is used for starting a laser light source and transmitting laser of the first band to a target object; and the first band receiving module is used for receiving reflected light of the first band from the target object and generating depth information of the target object based on the laser of the first band and the reflected light of the first band.

Description

technical field [0001] The present application relates to the field of image processing, in particular to a TOF system, an image processing method, and a storage medium. Background technique [0002] Time of Flight (TOF, Time Of Flight) system, that is, the sensor emits modulated near-infrared light and reflects it after encountering the target object. The sensor converts the distance from the target object by calculating the time difference or phase difference between light emission and light reflection. , to generate the depth information corresponding to the target object, and combined with traditional camera shooting, the three-dimensional outline of the object is imaged in a way that different colors represent different distances. At present, the mobile phones with TOF function on the market all use the 940nm band laser. The light in this band is beyond the range visible to the human eye and is invisible to the human eye. , since the light in the 940nm band is relative...
