Abstract

The invention relates to a quick digitalization device for a large-breadth aerial image. The quick digitalization device comprises a body provided with a shooting mechanism and a film carrying mechanism, a control unit connected with the shooting mechanism and a film transmission mechanism which is matched with the size of the film carrying mechanism or the size of a film in a film transmission direction, wherein the shooting mechanism and the film generate relative motion in the film transmission direction. By using the film transmission mechanism and the shooting mechanism which generate relative motion, after an image is scanned, the next image region can be automatically transmitted to a scanning region; therefore, the operation speed for scanning the images can be greatly improved; and due to the quick digitalization device, the same large-breadth film can be scanned within only three seconds.

Description

technical field [0001] The invention relates to an image digitization device, in particular to a large-format aerial image rapid digitization device. Background technique [0002] Existing scanners have a certain large-format film scanning function, but in specific practical applications, they also have the following two defects: [0003] 1. Lack of effective automatic film feeding and positioning function. According to the working principle of existing scanner sensors, current scanners can only scan and process single images. If it is necessary to scan a roll of continuous film, it is necessary to manually perform the film change positioning operation, which will greatly affect the work efficiency. [0004] 2. In order to ensure that the aspect ratio of the scanned image is consistent and does not stretch and deform, traditional scanners mostly use grating sensors as position measurement and feedback devices, and control the start of sampling according to the sensor displ...
