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] like 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 elect...

Abstract

The present invention relates to an image acquisition method, especially a continuous stacked image acquisition method for sorting large-leaf crops. In order to solve the problems in the background technology, a continuous stacked image acquisition method for sorting large-leaf crops is provided, including An encoder is set in the traveling direction of the large-leaf crops, and the encoder is electrically connected to at least two line-scan cameras. The encoder outputs a square wave signal to the line scan camera after rotating N circles, and the square wave signal is used as the line frequency signal of the line scan camera; 2) When the line scan camera receives the square wave signal from the encoder, the line scan camera continuously The image of the large-leaf crops is collected, and the present invention has the characteristics of realizing cascaded continuous feeding of the large-leaf crops, thereby improving detection efficiency.

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 ...
