METHOD FOR CONSTRUCTING A DEPTH MAP FROM A PAIR OF IMAGES Russian patent published in 2023 - IPC G06T7/593 G06T5/20 

FIELD: image data processing.

SUBSTANCE: invention is aimed to increase the accuracy of the depth map values. It is achieved by the fact that the claimed solution provides for stages in which first and second images are obtained from the first and second cameras; the rectification procedure of the first and second images is performed; the first and second image tensors are generated, where each element of the tensor represents the brightness value of the corresponding pixel; the tensors are normalized; the tensors are combined using an encoder; by means of a transformer, vector representations of at least one object contained in the tensor obtained at the previous stage are compared line by line to form a tensor containing information about the values of shifts of image pixels relative to each other; by means of a decoder, the first and the second shift maps are generated for the first and second images, containing said shift values, based on the tensor obtained at the previous stage; based on the values of the shift maps generated at the previous stage, an image depth map is formed.

EFFECT: increase in the accuracy of the depth map values.
