Abstract

The invention discloses a photographing question-searching method and system and handheld photographing equipment. The method comprises the steps that the handheld photographing equipment projects a dominant frame on a projection plane where test questions are located in response to a box selection instruction, wherein the dominant frame is used for box-selecting at least one to-be-tested test question in the projection plane; the handheld photographing equipment detects whether the projection direction of the projected dominant frame is perpendicular to the projection plane or not, wherein the photographing direction of a camera of the handheld photographing equipment is the same as that of the projection direction, and if not, the projection direction is adjusted till the projection direction is perpendicular to the projection plane; the handheld photographing equipment photographs the area where the dominant frame is located through the camera to obtain test question images, and then sends the test question images to electronic equipment to make the electronic equipment output the test question images and upload target to-be-tested test questions in the test question images to aserver to obtain target answer information corresponding to the target to-be-tested test questions. By means of the photographing question-searching method and system and the handheld photographing equipment, the question-searching efficiency and accuracy can be improved.
