Title:
IMAGE RECOGNITION AND READING DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/016758
Kind Code:
A1
Abstract:
An image recognition and reading device comprises a support frame (10), and an image recognition and reading element (20) mounted on the support frame (10). The image recognition and reading device further comprises a light source assembly (30) mounted on the support frame (10), and a filter assembly (40) mounted on the support frame (10) and configured to be opposite the light source assembly (30). The image recognition and reading element (20) defines an image recognition and reading region (50) in a recognition and reading direction thereof. The filter assembly (40) comprises a filter surface (421). The filter surface (421) and an optical axis (AC) of the image recognition and reading element (20) intersect, and form a second configured angle (α 2). An optical axis (BA) of the light source assembly (30) and the filter surface (421) intersect, and form a third configured angle (α 3). The light source assembly (30) emits light to the filter surface (421), and the light is reflected by the filter surface (421) to form reflected light. An optical axis of the reflected light extends towards the image recognition and reading region (50), and is configured to be close to the optical axis (AD) of the image recognition and reading element (20). The image recognition and reading device has a simple structure, low production costs, and high recognition and reading accuracy.
