US 2026/0289838 A1 · DATA PROCESSING METHOD, HEAT MAP GENERATION METHOD AND DEVICE

Abstract

Data processing method, heat map generation method and device are provided. The data processing method includes: receiving first physical coordinates of object(s) in an image in a scene coordinate system and calibration coordinates for a scene view, where the calibration coordinates represent size of view area corresponding to a scene in the scene view; dividing the scene in the scene coordinate system to obtain grids; allocating the first physical coordinate of object(s) to a corresponding grid based on the first physical coordinates of object(s) in the scene coordinate system; fusing the first physical coordinates of the object contained in each grid to obtain fused physical coordinates; generating initial hotspot data in an image coordinate system according to the calibration coordinates, actual width and height of the scene, and the fused physical coordinates; and transmitting the initial hotspot data to the terminal to generate a heat map within the scene.

A data processing method, comprising:

receiving a first physical coordinate of at least one object in an image in a scene coordinate system from an image collection apparatus, and receiving a calibration coordinate for a scene view from a terminal, wherein the calibration coordinate represents a size of a view area corresponding to a scene in the scene view;
dividing the scene in the scene coordinate system to obtain a plurality of grids;
for each of the plurality of grids, allocating the first physical coordinate of the at least one object to a corresponding grid based on the first physical coordinate of the at least one object in the scene coordinate system;
performing fusion processing on the first physical coordinate of the object contained in each grid to obtain a fused physical coordinate;
generating initial hotspot data that is based on an image coordinate system according to the calibration coordinate for the scene view, an actual width and an actual height of the scene, and the fused physical coordinate;
and
transmitting the initial hotspot data to the terminal, so that the terminal generates a heat map within the scene based on the initial hotspot data.
