Abstract

Embodiments of the present invention provide an image storage method, device, electronic equipment, and storage medium. In the method, the pixel data scanned in a preset partial area of ​​the scanning area is obtained as the first pixel data and stored in the storage space; The preset correction algorithm corrects the first pixel data to obtain the second pixel data and stores it in the storage space; when it is judged that the remaining space of the storage space meets the preset conditions, the pixel data scanned in the remaining area of ​​the scanning area is obtained as the third pixel The data is stored in the storage space, and the scanning mode of the remaining area is the preset second scanning mode; the third pixel data is corrected by using the preset correction algorithm to obtain the fourth pixel data and stored in the storage space. In the present invention, since the number of pixels scanned by using the preset second scanning mode is smaller than the number of pixels scanned by using the preset first scanning mode, the size of the image before correction is reduced, thereby improving the success rate of image storage.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image storage method, device, electronic equipment and storage medium. Background technique [0002] Because the optical collector has the advantages of being able to withstand a certain degree of temperature change, good stability and relatively low cost, it has been widely used in the field of public safety technology. [0003] However, because the optical collector is affected by the optical imaging mechanism, the scanned image has trapezoidal distortion, which brings certain difficulties to the later identification work. Therefore, in order to eliminate the adverse effects of trapezoidal distortion, after the scanned image is collected and stored, the scanned image can be corrected, and the corrected image can be obtained and stored, for example: the distorted image obtained by scanning with an optical collector The fingerprint image is stored, and the fi...
