The invention relates to a neighborhood information acquisition method and device, electronic equipment, a storage medium and a computer program product. The method comprises the following steps: determining a reference pixel point of a current coding block in an image; determining a target cache unit corresponding to the reference pixel point from the cache column according to the position information of the reference pixel point in the image; the target cache unit is a cache unit corresponding to a unit coding block sequence to which the unit coding block where the reference pixel point is located belongs at a preset inclination angle; each cache unit in the cache column is used for storing decoding information of the latest decoded unit coding block in a unit coding block sequence formed by corresponding unit coding blocks at a preset inclination angle; obtaining decoding information from the target cache unit, and obtaining neighborhood information of the current coding block according to the decoding inf
