Automatic zooming camera device and system, and method

Abstract

The invention relates to the technical field of design of high-speed cameras, and in particular relates to an automatic zooming camera device comprising a photoelectric sensor, an image collection board card, a power-driven sliding table control unit, a power-driven sliding table and a CMOS image sensor, wherein the photoelectric sensor can measure height information of a packet positioned on an express sorting line; the image collection board card is used for analyzing the height information of the packet to acquire power-driven sliding table gear information; the power-drive sliding table control unit is used for processing the power-driven sliding table gear information and acquiring a power-driven sliding table control signal; the power-driven sliding table is used for moving to a specified position according to the power-driven sliding table control signal; and the CMOS image sensor can be driven by the movement of the power-driven sliding table to translate. The invention also discloses an automatic zooming camera system and a method for achieving zooming of the camera by using the automatic zooming camera device. According to the automatic zooming camera device provided by the invention, the automatic zooming along with the height of the packet can be achieved.

Description

technical field [0001] The present invention relates to the technical field of high-speed camera design, in particular to an automatic zoom camera device, an automatic zoom camera system including the automatic zoom camera device, and a method for implementing camera zoom using the automatic zoom camera device. Background technique [0002] In the express sorting system, when the express package arrives under the camera lens, because the size of the express package is different, the distance between the express number on the package and the lens is different. If the camera can automatically zoom, it can quickly capture To get a clear image, quickly complete the identification of the express barcode, and then improve the speed of the express sorting system. [0003] In the prior art, cameras with a zoom function all adopt a zoom lens. Although there are many consumer zoom lenses on the market, the interface definitions of consumer zoom lenses are kept secret. Zoom lenses ...

AI Technical Summary

Problems solved by technology

Zoom lenses suitable for industrial cameras need to be customized, and smaller manufacturers cannot meet the technical requirements

At the same time, in order to make the camera have the advantages of high resolution and small size, the high-speed camera developed uses a large area array CMOS image sensor, but there is no zoom lens on the market that can adapt to such a large area array image sensor
