A document reading-order detection method comprises: a computer device identifying text blocks in a document image and constructing a block set; determining a start text block from the block set; performing, according to feature information of the start text block, a path searching operation on the start text block to determine a first text block of the block set corresponding to the start text block, the feature information of a text block comprising position information of the text block in the document image and layout information of the text block; iteratively performing the above steps until an order of execution of the path searching operations respectively corresponding to the text blocks in the block set can be uniquely determined; and determining the order of execution of the path searching operations corresponding to the text blocks in the block set, and obtaining, according to the order of execution, a reading-order of the text blocks in the document image.
