The external surface of objects 360 of this structure is spent checkout gear and is had following problem: skyborne attitude when the uncontrollable material of this structure falls, and therefore imaging angle is uncertain, and imaging easily produces distortion, cannot ensure the accuracy of gathered image. In addition, this structure can only detect one by one to material, and flux is subject to certain restrictions.
For these reasons, the outward appearance 360 of prior art is spent checkout equipment has detection speed slower, or the coarse problem of testing result.
Utility model content
Goal of the invention of the present utility model is to solve above-mentioned existing outward appearance 360 to spend the limitation of testing agency, provides a kind of detection speed fast, and the accurate multisample outward appearance 360 of testing result is spent testing agency.
A kind of multisample outward appearance 360 of the utility model is spent testing agency, comprises conveyer, frame, image capture module, lighting device and image recognition process unit;
Described conveyer is by frame central position, and transmission can be continuous motion;
Described image capture module comprises at least three image capture units, and the uniform ring of described image capture unit is located at described frame periphery; Described image capture unit is connected with frame by slide block, can in the chute of frame, adjust position; Described image capture unit single shot can be obtained the image of the special angle of single or multiple samples, all samples that pass through during twice shooting interval can cover;
Described lighting device comprises light source mounting blocks, and described light source mounting blocks is provided with light source, and for each image capture unit provides illumination, described light source is the highlighted light source that area is larger;
Described image recognition process unit is processed the single or multiple sample informations from image capture unit, and analysis result is corresponded to the relative position of each sample on conveyer, and the aggregation of data of different angles is integrated so that subsequent treatment.
Adopt after above structure, the utility model compared with prior art, has the following advantages:
A kind of multisample outward appearance 360 of the utility model is spent testing agency, comprises conveyer, frame, image capture module, lighting device and image recognition process unit; Described conveyer is by frame central position, and transmission can be continuous motion; Described image capture module comprises at least three image capture units, and the uniform ring of described image capture unit is located at described frame periphery; Described image capture unit single shot can be obtained the image of the special angle of single or multiple samples, all samples that pass through during twice shooting interval can cover; Described lighting device comprises light source mounting blocks, and described light source mounting blocks is provided with light source, for each image capture unit provides illumination; Described image recognition process unit is processed the single or multiple sample informations from image capture unit, and analysis result is corresponded to the relative position of each sample on conveyer and by different angles merger integration so that subsequent treatment. Adopt periphery at least three image capture units, can capture 360 of testee sights of being outside one's consideration from each angle simultaneously, imaging simultaneously, without repeatedly taking or rotation testee, employing vision-based detection real result is accurate; Meanwhile, owing to adopting multisample to detect simultaneously, can significantly improve detection flux. In addition, also can ensure to adopt the method for overlapping surveyed area to carry out repeatedly sample detecting to single sample under the prerequisite transmitting continuously, under the prerequisite that does not affect detection speed, improve the accuracy rate detecting.
As preferably, described image mounting blocks also comprises the crossbeam of slide block and connection sliding block, and described frame also comprises rail plate, and described rail plate and described slide block cooperatively interact. Image mounting blocks and frame utilize guide rail and slide block to slide up and down, light regulating and focal length, and Stability Analysis of Structures, principle is simple.
