METHOD AND APPARATUS FOR DETECTING POSITIONS OF OBJECT, COMPUTING DEVICE AND STORAGE MEDIUM Russian patent published in 2025 - IPC G06T7/73 

FIELD: physics.

SUBSTANCE: invention relates to a method and a device for detecting the position of an object, a computer device and a storage medium. Method comprises: obtaining image data, the image data comprising a target object; detecting two-dimensional first information about the position of the three-dimensional bounding box upon projection thereof into image data by inputting image data into a two-dimensional detection model, wherein the bounding box is configured to describe the position of the target object in 3D space; mapping the two-dimensional first position information to the three-dimensional second position information; and detecting third information on position of target object based on three-dimensional second information on position, wherein two-dimensional detection model comprises encoder, decoder and prediction network; and detecting two-dimensional first information on the position of the three-dimensional bounding box by inputting image data into the two-dimensional detection model comprises: obtaining a first image feature by encoding image data in an encoder; obtaining a second image feature by decoding the first image feature in a decoder; and mapping - in a prediction network - the second image feature to the two-dimensional first information on the position of the bounding box.

EFFECT: more accurate prediction of two-dimensional information on the position of the bounding box.
