Abstract

The invention discloses an image detection device comprising a reference part, a scanning part, and a light separation panel. The reference part is used for obtaining a brightness reference value; the scanning part is used for obtaining image information of a collected object; and the light separation panel arranged between the reference part and the scanning part is used for carrying out light separation on the reference part and the scanning part. With the device, stable image data collection can be realized; and influences of a temperature drift and a time drift can be reduced.

Description

technical field

[0001] The invention belongs to the field of image processing, in particular to an image detection device. Background technique

[0002] Image acquisition and image processing play a very important role in line-scan image sensors and line-scan image reading devices, especially in the field of line-scan image sensors and line-scan image reading devices used in the field of financial instruments. In the prior art, an image detection device is often used to collect images of objects (commonly referred to as target paper) such as coins and bills, and analyze the collected images to determine whether the target paper meets specific requirements, such as identification of bills. of authenticity. In the above process, the linear array image sensor and the linear array image reading device are the key to realize stable image data acquisition, ensure accurate and stable brightness, truly reproduce image data information, and then realize correct image data processing...
