Embodiment 1

[0027] First, refer to figure 1 An example electronic system 100 for implementing the testing method, device and smart device for the imaging quality of the device according to the embodiment of the present invention will be described.

[0028] Such as figure 1 A schematic structural diagram of an electronic system is shown, the electronic system 100 includes one or more processing devices 102, one or more storage devices 104, input devices 106, output devices 108 and one or more image acquisition devices 110, these components The interconnections are via bus system 112 and / or other forms of connection mechanisms (not shown). It should be noted that figure 1 The components and structures of the electronic system 100 shown are exemplary rather than limiting, and the electronic system may also have other components and structures as required.

[0029] The processing device 102 may be a gateway, or an intelligent terminal, or a device including a central processing unit (CPU) ...

Embodiment 2

[0036] This embodiment provides a method for testing the imaging quality of a device, which is executed by the processing device in the above-mentioned electronic system; specifically, when the above-mentioned electronic system is a smart device, the method is applied to the smart device, and the smart device pre-sets Standard images of faces of at least two objects to be compared are stored; for example, standard images of faces of two objects to be compared, object A and object B to be compared, are pre-stored in the smart device, or The smart device pre-stores three standard images of the faces of the objects to be compared A, B and C to be compared; the standard images are usually frontal images of the faces of the objects.

[0037] Such as figure 2 As shown, the method includes the following steps:

[0038] Step S202, collecting a test image of the subject of the target object through the photographing device on the smart device; the subject is a three-dimensional model...

Embodiment 3

[0049] This embodiment provides another method for testing the imaging quality of equipment, which is implemented on the basis of the above embodiments; in this embodiment, the focus is on the description of the testing methods for devices such as infrared cameras, near-infrared fill lights, and lampshades. As well as the specific comparison method of the test image and the standard image, and the specific method of determining the test result of the smart device according to the comparison result, the method for testing the imaging quality of the device includes the following steps:

[0050] Step 302, in an environment where the light intensity of the ambient light is lower than a preset intensity threshold, a test image of the target object is collected through the shooting device on the smart device; the shooting object is a three-dimensional model or a two-dimensional image of the face of the target object ; The target object is included in at least two objects to be compar...

Abstract

The invention provides a test method and device for image quality of equipment, and smart equipment, wherein the method comprises the following steps: collecting test images of a photographing objectof the target object by a photographing device on the smart equipment, wherein the photographing object is a three-dimensional model or a two-dimensional image of the face of the target object, and the target object is included in at least two objects to be compared; comparing the test images with the standard image to obtain a comparison result; and determining the test result of the smart equipment according to the comparison result. The test method and device can implement the test of the face recognition related hardware in the smart equipment, so that the imaging quality of the smart equipment is more stable, and the user needs for the face recognition related application in the smart equipment is satisfied.

Description

technical field [0001] The invention relates to the technical field of equipment testing, in particular to a testing method, device and intelligent equipment for equipment imaging quality. Background technique [0002] Smart devices (such as mobile phones, tablet computers, etc.) mostly have functions related to face recognition, such as face unlocking functions; these functions usually need to rely on infrared cameras, near-infrared fill lights, lampshades and other hardware devices to collect face images . Due to the errors in the manufacturing process of various devices, when the devices are assembled into a complete machine, there will be certain differences in imaging effects. If the quality of the generated image is poor, the functions related to face recognition will be affected, and it will be difficult to meet the expected standards of smart terminal products. [0003] However, there is no test solution for face recognition-related hardware in the related art, whi...
