Embodiment Construction

[0030] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Preferred embodiments of the application are shown in the accompanying drawings. However, the present application can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the application more thorough and comprehensive.

[0031] see figure 1 , an image recognition method, comprising step S100, step S200 and step S300.

[0032] Step S100, acquiring the detection light reflected from the surface of the object to be recognized to form a recognition image.

[0033] Specifically, the detection light is the light projected and reflected by the light emitter to the surface of the object to be identified. The recognition image is obtained by taking pictures of t...

Abstract

The invention relates to an image recognition method and device, electronic equipment and computer equipment, and the method comprises the steps of transmitting detection light through a light transmitter to irradiate the surface of a to-be-recognized object, obtaining the reflected detection light to form a recognition image, and obtaining the gray value of each pixel point and the correspondinggray change state according to the recognition image; and finally, performing comparative analysis according to the gray scale change state and a preset change state, and judging that identification is successful when the preset change state is met. Due to the fact that the characteristic that the surface of the to-be-recognized object is uneven is utilized, when the detection light irradiates thesurface of the to-be-recognized object, different numbers of detection light can be reflected, then a black-white image which the reflected detection light wants to collect is used as a recognition image, and then corresponding image recognition processing operation is carried out. According to the scheme, long-distance or short-distance limitation does not exist, meanwhile, recognition operationcan be effectively achieved within the power range, and the invention has the advantage of being high in imaging operation reliability.

Description

technical field [0001] The present application relates to the field of imaging technology, in particular to an image recognition method, device, electronic equipment and computer equipment. Background technique [0002] With the rapid development of science and technology, 3D imaging technology is becoming more and more mature. Common 3D imaging technologies are mainly divided into three categories, namely Time Of Flight (TOF), RGB binocular and structured light. TOF technology emits modulated near-infrared light through the sensor, which is reflected after encountering an object. The sensor calculates the distance of the scene to be photographed by calculating the time difference or phase difference between light emission and reflection to generate depth information. In addition, combined with traditional camera shooting, The three-dimensional outline of the object can be presented in the form of topographic maps with different colors representing different distances. RGB ...
