Title:
IDENTIFICATION APPARATUS AND METHOD
Document Type and Number:
WIPO Patent Application WO/2020/258300
Kind Code:
A1
Abstract:
Provided are an identification apparatus and method. The apparatus comprises: a distance sensor used for measuring a first distance between an infrared sensor and an identification object; the infrared sensor, which is used for photographing a first image of the identification object at a preset exposure; and a processor used for determining the preset exposure according to the first distance, calculating the actual exposure of the infrared sensor according to the first image, and performing, when the actual exposure is in a preset range, identification processing on the identification object by using the first image. The present application can precisely determine a preset exposure of an infrared sensor. During 2D identification, there is no need to pre-photograph an image to determine whether the exposure is appropriate, which increases the identification speed of the apparatus; and furthermore, compared with the infrared sensor and a fill light, a distance sensor has lower energy consumption, thereby reducing the energy consumption of the apparatus. During 3D identification, by means of the apparatus, the exposure is adjusted according to the first distance, so that the apparatus is prevented from operating in a high-energy-consumption mode for a long time, reducing the energy consumption of the apparatus.
