Depth calculation processor, data processing method and 3d image device

A data processing method, comprising:

• independently receiving a first image data from different image sensors through at least two input ports, wherein the first image data comprises at least a structured light image acquired under projection of a structured light;
• selectively receiving the first image data from the input ports;
• performing a calculation process on the first image data to obtain a second image data;
• and
• outputting the second image data to a host device through at least one output port,
• wherein performing the calculation process on the first image data comprises performing a depth calculation process on the structured light image to obtain a depth map.

A three-dimensional (3D) image device, comprising:

• a depth calculation processor;
• a projector coupled to the depth calculation processor and configured to generate a structured light pattern under control of the depth calculation processor, the structured light pattern being projected to a target object;
• and
• a first image acquisition unit coupled to the depth calculation processor and configured to acquire a structured light image of the target object and output the structured light image to the depth calculation processor,
• wherein the depth calculation processor includes:
• at least two input ports configured to receive the structured light image;
• an input switch coupled to the input ports and configured to convey all or some of the structured light image from the input ports;
• a data processing engine coupled to the input switch and configured to perform a calculation process on the structured light image to generate an output image, wherein the output image includes a depth map and wherein the data processing engine comprises at least a depth processing engine configured to perform a depth calculation process on the structured light image to obtain the depth map;
• and
• at least an output port coupled to the data processing engine and configured to output the output image to a host device.
