Code scanning equipment with automatic calibration camera and millimeter wave radar

Abstract

The invention relates to code scanning equipment with an automatic calibration camera and a millimeter wave radar, which comprises a code scanning device and a calibration device, and is characterized in that the calibration device is arranged in front of the code scanning device; and a calibration plate is arranged on one side, directly facing the code scanning equipment and the millimeter-wave radar range finder, of the calibration device. According to the invention, the code scanning camera and the millimeter wave radar of the code scanning equipment are automatically, accurately, efficiently and stably calibrated and detected, the calibration detection information can be intelligently sorted, the information is timely stored and processed, and the calibration detection is timely completed; when a two-dimensional code of a cargo is read, the distance between the camera and the two-dimensional code is rapidly measured through the millimeter wave radar range finder, and the focal length of the camera can be automatically adjusted through the movement of the front-back structure, the up-down structure and the left-right structure, so that the three-dimensional data of the spatial position of the camera is corrected, and a high-quality two-dimensional code image is read; the three cameras are arranged side by side, and a larger reading angle can be obtained, so that the moving stroke of the mechanism is shortened, and the code scanning time is shortened.

Description

technical field [0001] The invention relates to an automatic code scanning device, in particular to a code scanning device with an automatic calibration camera and a millimeter-wave radar. Background technique [0002] In order to obtain the information contained in the miniature, invisible, and different-shaped QR codes, an automatic code-scanning device equipped with a camera and millisecond wave radar has emerged as the times require. At present, most of the existing code scanning devices on the market have a small range of normal code scanning work, and the flexibility of automatic correction is not high, and the efficiency is low. When a larger reading range is required, in many cases, a large sacrifice is required. In exchange for the scanable range of the itinerary; when there are many goods, the goods will often enter the scanning range from different angles. Difficulty, the inability to scan accurately will affect the work efficiency. At this time, the method of ma...
