Problems solved by technology

And jujube can be simplified into a cylindrical body model with one end large and the other end small, so the image acquisition system can only collect the cylindrical surface of the jujube column, but the images of the top and bottom of the jujube are not captured.

Embodiment Construction

[0013] Specific embodiments are given below in conjunction with the accompanying drawings.

[0014] An embodiment of the present invention is a jujube comprehensive image information acquisition device with 3 channels side by side, specifically as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 shown. The jujubes in a single row are transported horizontally to the upper end of the trough-shaped slideway 3. Since the rolling friction angle of the jujube is smaller than the sliding friction angle, the slideway is installed on the frame 1 inclined at an angle of 10° to 15° from the horizontal direction. The heart rolls down along the slideway; under the action of the crank rocker mechanism 5, the baffle plate 4 with bracket moves back and forth up and down in the open seam at the end of the slideway, so that the red dates stop at the end of the slideway for 3 times, because the fruit shape of the red dates is small , the jujube rotates 120° to 180° on its own axis ev...

Abstract

The invention relates to a comprehensive image information acquisition device for classification of red dates, which is used for red date classification equipment. Aiming at the problem that existing national red date classification equipment based on machine vision cannot acquire image information of two end faces of the red dates, the comprehensive image information acquisition device comprises a rack, and a power machine, a slide way assembly, a transmission mechanism, a guiding mechanism and a rotary groove mechanism which are mounted on the rack. The image information acquisition device acquires all image information of cylindrical surfaces of the red dates at the tail end of an inclined slide way; the red dates pass through the guide mechanism so that transverse arrangement of the red dates is changed to vertical arrangement and the red dates vertically fall into a rotary groove; an image acquisition system finishes the acquisition of the top and bottom image information of the red dates as well as the unloading of the red dates through different rotary angles of the rotary groove; and the unloading is simple and comprehensive image information of the red dates is acquired so that the follow-up detection on the surface quality of the red dates is accurate, and the classification precision of the red dates is improved.

Description

technical field [0001] The invention relates to a comprehensive image information collection device for jujube grading used in jujube grading equipment. Background technique [0002] At present, jujube jujube grading equipment based on machine vision used in China is mostly a double-friction roller mechanism. Since there is a speed difference between the forward speed of the double-cone roller and the speed of the friction belt, its friction on the friction belt The lower rotation drives the object under test to rotate around its central axis at the same time, presenting the surface information under the lens of the image acquisition system, and the lens continuously collects multiple frames of images at a certain frequency. And jujube can be simplified into a cylindrical body model with a large end and a small end, so the image acquisition system can only collect the cylindrical surface of the jujube cylindrical body, but does not collect the images of the top and bottom of...
