Embodiment 1

[0036] figure 1 A schematic flow chart of the first material detection method provided in the embodiment of the present application is shown, and the details are as follows:

[0037] In S101, a picture to be tested is acquired.

[0038] The picture to be tested in the embodiment of the present application is a picture taken by a camera in a target detection area, and the target detection area may specifically be an area where materials pass through during conveyance. Exemplarily, as figure 2 As shown, a schematic diagram of an application scenario according to the embodiment of the present application is given, wherein the materials are scattered on the transmission belt through a mechanical device, and the area surrounded by the shading curtain in the figure is the target detection area, and the There is a light source board and a camera; when the material reaches the target detection area along with the conveying belt, the camera starts to shoot the target detection area ...

Embodiment 2

[0091] Figure 6 A schematic flowchart of the second material detection method provided by the embodiment of the present application is shown, and the execution subject in the embodiment of the present application is a terminal device. Specifically, this embodiment adds the target template loading step S601 on the basis of the previous embodiment. S602-S606 in the embodiment of the present application are exactly the same as S101-S105 in the previous embodiment. For details, please refer to the previous implementation Relevant descriptions of S101-S105 in the example are not repeated here. Such as Figure 6 Step S601 in the shown material detection method is described in detail as follows:

[0092] In S601, a material table is acquired, and a target template is loaded from pre-built material templates according to the material table.

[0093] The pre-built material templates in the embodiment of the present application are multiple templates constructed and stored in advanc...

Abstract

The invention is suitable for the technical field of image processing, and provides a material detection method and device, and terminal equipment, and the method comprises the steps: obtaining a to-be-detected image; determining a first material position and a corresponding matching template according to contour feature information of the to-be-detected imageand a pre-loaded target template; screening out a second material position from the first material position according to target color feature information corresponding to the first material position in the to-be-detected picture and template color feature information carried by the matching template; screening out a third material position from the second material position according to target detail feature information corresponding to the second material position in the to-be-detected picture and template detail feature information carried by the matching template; and determining information of a target material according to thethird material position and a matching template corresponding to the third material position. According to the embodiment of the invention, the accuracy and flexibility of material detection can be improved.

Description

technical field [0001] The present application belongs to the technical field of image processing, and in particular relates to a material detection method, device and terminal equipment. Background technique [0002] With the advancement of industrial manufacturing intelligence, in the field of automated sorting, flexible sorting technology continues to develop, especially the flexible automated sorting technology based on robotic arms and machine vision systems. The flexible sorting technology based on the robotic arm and machine vision mainly refers to the use of the machine vision system to complete the identification and grab point positioning of the materials to be sorted, and then the robotic arm calls the information output by the vision system to grab the materials to complete the sorting task . [0003] In the above sorting tasks, the detection and identification of the materials to be sorted is a very critical link. However, in the prior art, due to the variety ...
