摘要:【中文】本发明提出一种感兴趣区域查询方法、装置、设备和计算机存储介质,所述方法包括:确定感兴趣区域的边界;对所述感兴趣区域进行网格化处理;获取用户的位置坐标所在的网格,确定该网格对应的感兴趣区域;当用户所在的网格位于感兴趣区域的边界时,则判断用户的位置坐标是否位于所述感兴趣区域内。本发明实施例通过网格化处理可以快速锁定对应的感兴趣区域,减少计算量。然后再针对感兴趣区域的边界进行精确的定位计算,从而可以快速精确地锁定用户位置所在的感兴趣区域。 【EN】The invention provides a method, a device, equipment and a computer storage medium for inquiring a region of interest, wherein the method comprises the following steps: determining the boundary of the region of interest; gridding the region of interest; acquiring a grid where the position coordinates of the user are located, and determining an interested area corresponding to the grid; and when the grid where the user is located is positioned at the boundary of the region of interest, judging whether the position coordinates of the user are positioned in the region of interest. According to the embodiment of the invention, the corresponding region of interest can be quickly locked through gridding processing, so that the calculation amount is reduced. And then, the boundary of the region of interest is precisely positioned and calculated, so that the region of interest where the user is located can be quickly and precisely locked.
