Problems solved by technology
The zoom system using the existing camera is usually realized by the traditional method, that is, using different concave-convex lens combinations to drive the zoom through a mechanical gear device. Large, easy to wear and low life; in recent years, Europe and the United States and other countries have developed a liquid zoom lens, which can achieve the zoom function of the human eye to a certain extent, but it is prone to leakage and other problems due to the use of liquid optical media

Embodiment Construction
[0022] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0023] like figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Image 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 As shown, the present invention installs linear stepper motor 1 and base 3 respectively on both sides of base plate 8, wherein stepper motor 1 is fixed on the linear stepper motor frame through stepper motor fixing hole 9, and base 3 passes through base The seat threaded hole 7 is fixed on the base plate, and the center of the base 3 is provided with a stepped through hole. The small hole of the stepped through hole faces the side of the linear stepper motor 1. The bionic eye solid-state zoom lens 6 is a stepped cylinder, and the stepped cylinder is large. The center of the end face has a first protruding spherical segment, which is the front surface 17 of the bionic eye solid-state zoom lens, and the center of the sma...

The invention discloses a bionic eye device with zooming characteristics. A linear stepping motor and a base are respectively installed on two sides of a bottom plate, a bionic eye solid-state zooming lens and a compression disk are installed in the base, a boss on the compression disk is contacted with the zooming lens, a charge coupled device (CCD) sensor circuit board is installed on the small-hole end face of the base, and the linear stepping motor drives the compression disk through a U-shaped connecting member to extrude and control the zooming lens to achieve zooming so as to enable different target objects to be imaged on the CCD sensor circuit board. The bionic eye device with zooming characteristics utilizes the linear stepping motor to control the zooming lens to zoom, imitates the human ciliary muscle to drive a crystalline lens to achieve a zooming process, has the advantages of being simple in structure, compact in size, easy to manufacture, low in cost, embeddable and the like, is provided with an image sensor for imaging, can utilize an image algorithm to analyze and process acquired image information, outputs instructions to an actuator so as to achieve zooming control, and forms a zooming system with controllable closed-loop focal length.
Description
technical field [0001] The invention relates to a robot vision device, in particular to a bionic eye device with zoom characteristics. Background technique [0002] With the continuous improvement of the level of science and technology, industrial automation is becoming more and more popular, and the bionic robot is a robot with a high degree of automation, and it is also the focus of research by scholars at home and abroad. More than 80% of the information that humans perceive in the objective world is obtained through eyes. The role of the human eye for human beings is self-evident. Similarly, the visual system, as an important way for robots to obtain external information, occupies a particularly important position in the research of intelligent robots. Robot technology is used in various industries such as automobiles, robots, semiconductors, agriculture, video surveillance security, traffic management, medical treatment, printing, packaging, satellite remote sensing, s...
