Abstract
(EN)
A texture recognition device and an operation method therefor. The texture recognition device (100) comprises a light source array and an image sensor array (120). The light source array comprises multiple light sources (111). The image sensor array (120) is provided at one side of the light source array, and comprises multiple image sensors (121) configured to receive the light emitted from the multiple light sources (111) and reflect from the texture to the image sensor (121) for acquiring a texture image. Each of the image sensors (121) comprises multiple signal switches. A signal of each of the image sensors (121) is read by multiple signal switches to form an image pixel of the texture image. The texture recognition device (100) is capable of more quickly obtaining a texture image having a high resolution and accuracy.

La présente invention concerne un dispositif de reconnaissance de texture et un procédé de fonctionnement associé. Le dispositif de reconnaissance de texture (100) comprend un réseau de sources de lumière et un réseau de capteurs d'images (120). Le réseau de sources de lumière (1) comprend de multiples sources de lumière (111). Le réseau de capteurs d'images (120) est disposé sur un côté du réseau de sources de lumière, et comprend de multiples capteurs d'images (121) configurés pour recevoir la lumière émise par les multiples sources de lumière (111) et réfléchir depuis la texture vers capteur d'image (121) afin d'acquérir une image de texture. Chacun des capteurs d'images (121) comprend de multiples commutateurs de signal. Un signal de chacun des capteurs d'images (121) est lu par de multiples commutateurs de signal pour former un pixel d'image de l'image de texture. Le dispositif de reconnaissance de texture (100) est capable d'obtenir plus rapidement une image de texture ayant une haute résolution et une haute précision.
