Abstract

The invention provides an image sensor. The image sensor includes: a housing; a circuit board arranged in the frame body; a lens structure, which is arranged on the frame body, wherein the lens structure and the circuit board are arranged at intervals, and the circuit board is located in the extension direction of the optical axis of the lens structure; a light source structure, which is arranged on the side, away from the circuit board, of the lens structure and comprises at least one first light source structure and at least one second light source structure, wherein the first light source structures and the second light source structures are arranged in the extension direction of the optical axis of the lens structure in a spaced mode. The detection object surface of the image sensor is located on one side of the light source structure away from the lens structure. An irradiation area of the first light source structure and an irradiation area of the second light source structure at least partially coincide on the detection object surface. The problem that an image sensor in the prior art is poor in imaging quality is solved.

Description

technical field [0001] The present invention relates to the field of image sensor equipment, in particular to an image sensor. Background technique [0002] In the field of machine vision, it simulates the way of biological vision imaging and processing information, helping robots extract, process and understand the extracted information, so that it can automate operations accurately, efficiently and safely. The importance of machine vision is mainly reflected in: guidance and positioning, appearance inspection, high-precision monitoring and image recognition. Among them, in industrial automation testing, while improving efficiency, the requirements for detection of small defects are getting higher and higher, and the market in this area will continue to expand in the future. [0003] Based on the high-speed and high-resolution detection requirements, a lens imaging product is designed. In the actual test, the product needs to have a strong enough light brightness to clear...
