Assignee: AMBARELLA INTERNATIONAL LP
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 0:
1. An apparatus comprising:
an interface configured to receive pixel data;
a structured light projector configured to generate a structured light pattern; and
a processor configured to (i) process said pixel data arranged as video frames, (ii) perform operations using a convolutional neural network to determine a binarization result and an offset value and (iii) generate a disparity map and a depth map in response to (a) said video frames, (b) said structured light pattern, (c) said binarization result, (d) said offset value and (e) a removal of error points, wherein said convolutional neural network:
(A) performs a partial block summation and an average on said video frames to generate a convolution result,
(B) compares said convolution result to an ideal speckle value to determine said offset value,
(C) generates an adaptive result in response to performing a convolution operation to add said offset value to said video frames,
(D) compares said video frames to said adaptive result to generate said binarization result for said video frames, and
(E) removes said error points from said binarization result.
