Embodiment Construction

[0036] In order to make the purpose, technical solution and advantages of the present invention clearer, the following will further describe the implementation of the present invention in detail in conjunction with the accompanying drawings.

[0037] The first embodiment of the present invention relates to a visual detection method of a camera on a mobile terminal, such as figure 1 shown.

[0038] In step 101, the visual inspection machine is used to capture a picture of a mobile terminal that has no abnormality detected manually (that is, a good product) to obtain a standard picture. Usually, when the mobile terminal moves into the sensing range of the sensor installed in the visual inspection machine, the camera on the visual inspection machine is triggered to take pictures of the mobile terminal to obtain a standard picture.

[0039] In step 102, a feature area is selected from the captured standard picture, where the feature area refers to a uniquely identifiable area, su...

Abstract

The invention discloses a visual detection method for a camera on a mobile terminal and a control device. The method comprises the following steps: taking a picture of a to-be-detected mobile terminal through a virtual detector; searching for a camera area image on the picture taken and detecting the edge contour thereof; if the maximum of gradient of an edge shape function detected is higher than or equal to a preset maximum of standard gradient, judging that a camera is installed properly; otherwise, judging that a camera is missing. Through the method, whether a camera is installed properly on a mobile terminal can be detected automatically, the labor cost is lowered, the detection time is shortened, and the probability of missed detection and false detection is minimized.

Description

technical field [0001] The invention relates to a visual detection technology, in particular to a visual detection technology of a mobile terminal camera. Background technique [0002] Visual inspection is to use machines instead of human eyes for measurement and judgment. Visual inspection refers to the conversion of captured objects into image signals through machine vision products (i.e., image capture devices), which are transmitted to a dedicated image processing system, and converted into digital signals according to pixel distribution, brightness, color and other information; Various calculations are performed on the signal to extract the characteristics of the target, and then the on-site equipment actions are controlled according to the results of the discrimination. Is a valuable mechanism for production, assembly or packaging. It is invaluable in its ability to detect defects and prevent defective products from being shipped to consumers. [0003] In foreign co...
