Problems solved by technology

[0002] The image collection of existing large-leaf crops is usually single-page collection, that is, a single large-leaf crop passes through the image collection camera, and the image collection camera performs image collection on it, resulting in too slow image collection speed. If a continuous image collection device is used to collect images continuously When the image of large-leaf crops is large, the belt will be fast and slow during transmission, which will cause the image taken in this section to be stretched or compressed, which will affect the subsequent process or cause a high misjudgment rate.

Embodiment Construction

[0015] The present invention will now be described in further detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0016] Such as figure 1 and figure 2 Shown is a continuous stacked image acquisition method for sorting large-leaf crops. The stalk of the large-leaf crop 1 is clamped and transported by two belts 2. The motor, driving wheel and driven wheel that drive the belt 2 to rotate are omitted in the figure and other parts.

[0017] An encoder 3 is first installed in the traveling direction of the large-leaf crop 1, and the encoder 3 compiles signals or data and converts them into devices that can be used for communication, transmission and storage of signals. Encoder 3 converts angular displacement or linear displacement into el...

Abstract

The invention relates to an image acquisition method, in particular to a continuous stacked image acquisition method for large-leaf crop sorting. In order to solve the problems in the background art,the invention provides a continuous laminated image acquisition method for sorting large-leaf crops, which comprises the following steps: arranging an encoder in the advancing direction of the large-leaf crops, electrically connecting an encoder with at least two line scanning cameras, and aligning line scanning cameras with the large-leaf crops. An image acquisition method comprises the followingsteps: (1) driving the encoder to rotate when the big-leaf crop advances, outputting square wave signals to the line scanning cameras after the encoder rotates for N circles, and taking the square wave signal as a line frequency signal of the line scanning camera; and (2) after the line scanning cameras receive the square wave signal sent by the encoder, with the line scanning cameras continuously collecting images of the large-leaf crops. The invention has the advantages that stacked continuous feedings of the large-leaf crops can be achieved, and detection efficiency is improved.

Description

technical field [0001] The invention relates to an image acquisition method, in particular to a continuous stacked image acquisition method for sorting large-leaf crops. Background technique [0002] The image collection of existing large-leaf crops is usually single-page collection, that is, a single large-leaf crop passes through the image collection camera, and the image collection camera performs image collection on it, resulting in too slow image collection speed. If a continuous image collection device is used to collect images continuously When the image of large-leaf crops is used, the belt will be fast and slow during transmission, which will cause the image taken in this section to be stretched or compressed, which will affect the progress of the subsequent process or cause high misjudgment rates. Contents of the invention [0003] The technical problem to be solved by the present invention is: in order to solve the problems in the background technology, provide ...
