The image processing device testing method provided by the present application will be described in detail below with reference to the accompanying drawings.

1 is a flow chart of a method of testing an image processing apparatus according to an embodiment of the present application.

As shown in FIG. 1, the image processing apparatus testing method includes the following steps:

Step 101: Determine a current target shooting mode according to a preset test scenario.

Step 102: Adjust an operating state of the light emitting component and the camera according to the target shooting mode to acquire an actual image corresponding to the target shooting mode.

Please refer to FIG. 2 and FIG. 6 . Specifically, the image processing device testing method provided by the present application may be performed by the image processing device testing device 100 provided by the embodiment of the present application. Hereinafter, the testing device 100 may be configured. In any electronic device 400 having the image processing device 20, the reliability of the image processing device 20 in the electronic device 400 is tested.

In actual use, the test plan can be preset according to the actual test needs. The test plan can include one or more shooting modes, the number of tests for each shooting mode, the test sequence between the shooting modes, and the like.

It should be noted that the image processing device 20 in the embodiment of the present application includes a light emitting component and a camera. Correspondingly, the process of testing the image processing device 20 may be testing the light emitting component, or the camera, or the light emitting component and the camera. The process of reliability. Therefore, in this embodiment, each shooting mode may correspond to at least one lighting component, or to at least one camera, or to at least one lighting component and a camera.

During the specific execution of the test plan, each time the shooting mode is switched, the current target shooting mode can be determined according to the test plan, thereby adjusting the working state of the corresponding lighting component and the camera to ensure the working state of the lighting component and the camera. , matching with the target shooting mode, and then obtaining the actual image corresponding to the current shooting mode, thereby ensuring the authenticity of the actual image and improving the reliability and accuracy of the test.

In the embodiment of the present application, if the image processing device 20 includes N kinds of light-emitting components and M types of cameras, N and M are both positive integers greater than 1. The foregoing step 102 is as an example, and may include:

Determining a lighting mode of the target lighting component, the target lighting component, and a target camera according to the target shooting mode;

In actual use, the N types of light-emitting components may include one or more of a floodlight 22 and a laser light 24; and the M cameras may include one or more of a laser camera 21 and a visible light camera 23, and the like.

In addition, the light emission mode may include one or more of a light emission frequency, a light emission pattern, or a light emission duration.

Step 103: Determine whether the actual image matches the ideal image corresponding to the target shooting mode.

Step 104, if matched, determines that image processing device 20 is currently reliable.

The ideal image corresponding to the target shooting mode refers to an image acquired by the image processing device 20 when the operating states of the components are consistent with the operating states of the components in the target shooting mode, and each component is reliable.

In actual use, before testing the image processing apparatus 20, it is necessary to first determine a test scene map, that is, an ideal image, which can be acquired when each component in the image processing apparatus 20 is reliable and is in different working states. Then, during the test, it is determined whether the components in the image processing apparatus 20, such as the light-emitting component, the camera component, or the image sensor component, are reliable by judging whether the actual image acquired at the time of the test matches the corresponding ideal image.

It can be understood that, in the embodiment of the present application, the actual image acquired during the testing process and the ideal image acquired in advance, the corresponding subject and the external illumination environment are the same.

It can be understood that the actual image corresponding to the target shooting mode can be acquired after each specific execution of the test scheme. For example, the target shooting mode corresponds to that the light-emitting component is a laser light 24, and the camera component is a laser camera 21, then after the laser light 24 is configured to emit structured light according to the target shooting mode, and the emitted structured light is projected onto the imaged object, the laser camera 21 is used. The structured light image can be acquired as an actual image corresponding to the target shooting mode.

Furthermore, the actual image is matched with the ideal image corresponding to the target shooting mode by the correlation algorithm or the model. If the actual image matches the ideal image corresponding to the corresponding target shooting mode, the current laser light 24 and the laser camera 21 are still reliable. If the actual image does not match the corresponding ideal image, it indicates that the reliability of the current laser lamp 24 cannot meet the requirements, or the reliability of the laser camera 21 cannot meet the requirements, or the reliability of the laser lamp 24 and the laser camera 21 are already satisfied. The requirements are not met, or the reliability of the image sensor is no longer sufficient.

Further, when determining whether the actual image matches the ideal image corresponding to the target shooting mode, the following can be implemented in various ways:

Example one

It is judged whether the brightness of the actual image matches the brightness of the ideal image.

In actual use, the brightness of the actual image can be determined in various ways, such as from an Image Processor Processor (ISP); or, due to the Automatic Exposure Control (AEC) Automatically compensates the shooting image according to the brightness of the shooting scene to obtain a normal exposure image. Therefore, the brightness of the actual image can also be obtained directly from the AEC; or, the histogram statistical analysis can be performed on the actual image. In order to determine the brightness of the actual image, etc., this embodiment does not limit this.

Since the actual image corresponds to the same subject and the illumination environment is the same, and the performance of the light-emitting component in the image processing apparatus 20 changes, or the performance of the camera changes, or the performance of the image sensor changes, The actual image obtained is different from the brightness of the ideal image. Therefore, in the embodiment of the present application, whether the reliability of each component in the image processing device 20 can still be determined by determining whether the brightness of the actual image matches the brightness of the ideal image. fulfil requirements.

Example 2 determines whether the resolution of the actual image matches the resolution of the ideal image.

In actual use, the resolution of the actual image can be obtained in various ways, such as from an image processor (Image Signal Processor, ISP for short); or, according to the size of the actual image, etc., this embodiment does not Make a limit.

Since the actual image and the ideal image correspond to the same subject and the illumination environment is the same, when the performance of the camera changes, or the performance of the image sensor changes, the resolution of the obtained actual image is different from that of the ideal image. In the embodiment of the present application, whether the reliability of each component in the image processing apparatus 20 can still meet the requirements can be determined by determining whether the brightness of the actual image matches the resolution of the ideal image.

It should be noted that the above two methods for determining whether the actual image matches the corresponding ideal image are merely exemplary descriptions. In actual use, any image parameter may be used as needed to measure whether the actual image matches the ideal image.

In a specific implementation, the image processing device 20 further includes a processing component that processes the actual image, such as a micro control unit (MCU) or the like, to process the actual image acquired by the camera. For example, FIG. 2 is a schematic structural diagram of an image processing apparatus 20 according to an embodiment of the present application.

As shown in FIG. 2, the image processing apparatus 20 includes a laser camera 21, a floodlight 22, a visible light camera 23, a laser light 24, a micro control unit MCU 29, and a processing chip 30.

The micro control unit MCU29 includes Pulse Width Modulation (PWM), depth engine 28, bus interface 26, and Random Access Memory (RAM); Environment (Rich Execution Environment, REE for short) and Trusted Execution Environment (TEE), REE and TEE are isolated from each other.

In the image processing apparatus 20 shown in FIG. 2, the PWM 25 is used to modulate the floodlight to generate infrared light, and/or to modulate the laser light 24 to emit structured light, and to project the emitted infrared light and/or structured light onto the imaged object. . The laser camera 21 is used to acquire a structured light image and send the acquired structured light image to the depth engine 28. The depth engine 28 calculates the depth of field data corresponding to the imaged object based on the structured light image and transmits the depth of field data to the trusted application via the bus interface 26. The bus interface 26 includes an MIPI bus interface, an I2C synchronous serial bus interface, and an SPI bus interface that interacts with trusted applications running in a trusted execution environment.

That is to say, after determining the current target shooting mode (ie, the corresponding lighting component and the working state of the camera), the actual image corresponding to the target shooting mode can be obtained by adjusting the working states of the corresponding lighting component and the camera.

Correspondingly, the current reliability of the image processing apparatus 20 is determined, that is, the reliability of each component in the image processing apparatus 20 corresponding to the current target photographing mode is determined. For example, if the current target shooting mode is, the laser light 24 is controlled to emit a structured light of a preset pattern, and then the laser camera 21 is used to acquire the actual image. Then, when it is determined that the actual image does not match the ideal image, it can be determined that the reliability with at least one component in the target shooting mode, such as the laser lamp 24, or the laser camera 21, is no longer sufficient.

The image processing device testing method of the embodiment first determines a current target shooting mode according to a preset testing scheme, and then adjusts an operating state of the lighting component and the camera according to the target shooting mode, and further obtains an actual image corresponding to the target shooting mode according to the target shooting mode. The reliability of the image processing apparatus 20 is determined by the matching of the ideal image. Thereby, the reliability of the image processing apparatus 20 is tested by the actual use scenario of the analog image processing apparatus 20, and the test result is true and reliable.

FIG. 3 is a flowchart of a method of testing an image processing apparatus according to another embodiment of the present application.

As shown in FIG. 3, the image processing apparatus testing method includes the following steps:

In step 201, each image type corresponding to each use scene of the image processing apparatus 20 is determined.

Step 202: Determine a preset test solution according to each image type.

The usage scenario of the image processing device 20 may be determined according to an application running in the electronic device where the image processing device 20 is located, an operating state of the application, and the like. For example, if the application currently running in the current electronic device is a shopping application, the testing device 100 may determine that the image processing device 20 is in the payment scenario; or the application currently running by the electronic device 400 is a social application, and the application is currently being applied. In the login state, the testing device 100 can determine the scene in which the image processing device 20 is in the authentication mode. Alternatively, if the electronic device 400 is currently in the lock screen state, the testing device 100 can determine that the image processing device 20 is in the unlocked state of the electronic device 400. .

In actual use, since the different usage scenarios have different requirements on the type, accuracy, and reliability of the image, correspondingly, the types of components in the image processing device 20 and the reliability levels of the components are different. The currently corresponding image type may be determined according to the usage scenario of the image processing device 20, and then the preset test scenario is determined according to the currently corresponding image type.

For example, when the scene is requested, the image is required to be a three-dimensional structured light image, and then the corresponding test scheme is: controlling the laser light 24 and the laser camera 21 to be turned on when the payment scene is determined; and the image is required to have a higher resolution when the scene is electronically unlocked. The color image, then the test scheme corresponding to the electronic unlocking scene is determined as follows: the floodlight and the visible light camera, and the camera captures the image at the highest resolution, which is not limited in this embodiment.

It should be noted that the preset test solution determined by the embodiment of the present application may include only one shooting mode, and may also include multiple shooting modes, a sequence of multiple shooting modes, and a number of tests corresponding to each shooting mode. Wait. In actual use, the number and type of shooting modes included in the preset test plan, and the test sequence and the number of times corresponding to each shooting mode, respectively, may be determined according to the attributes of the electronic device 400 in which the image processing device 20 is located.

For example, if the number of times the electronic device 400 performs electronic unlocking by the image processing apparatus 20 is much larger than the number of times of payment by the image processing apparatus 20, the number of tests for testing the corresponding shooting mode of the electronic unlocking in the preset test scheme is used. Or the frequency may be more than the number of tests or the frequency of the shooting mode used to test the payment.

Step 203: Determine a current target shooting mode according to a preset test scenario.

Step 204: Determine a lighting mode of the target lighting component, the target lighting component, and a target camera according to the target shooting mode.

Step 205, according to the illumination mode, controlling the target illumination component to emit light, and acquiring the actual image by using the target camera.

During the specific execution of the test plan, each time the shooting mode is switched, it is necessary to determine the current target shooting mode according to the test plan, and then adjust the working state of the corresponding lighting component and the camera to ensure that the target shooting mode can be acquired. The corresponding actual image can ensure the authenticity of the actual image and improve the reliability and accuracy of the test.

In the embodiment of the present application, the image processing device 20 includes N kinds of light-emitting components, and M types of cameras, wherein N and M are positive integers greater than 1.

The N types of light-emitting components may include one or more of a floodlight 22 and a laser light 24; and the M cameras may include one or more of a laser camera 21 and a visible light camera 23.

The light emitting mode may include one or more of a light emitting frequency, a light emitting pattern, and/or a light emitting duration.

Thereby, the target light-emitting component can be controlled to emit light in accordance with the light-emitting mode, and the actual image can be acquired by the target camera. For example, the laser light 24 emits structured light and projects the emitted structured light onto the imaged object. The laser camera 21 is used to acquire the structured light image as the actual image corresponding to the target shooting mode.

In step 206, it is determined whether the actual image matches the ideal image corresponding to the target shooting mode. If yes, step 207 is performed; otherwise, step 208 is performed.

At step 207, it is determined that the image processing device 20 is currently reliable.

Step 208: Determine whether the number of matching failures corresponding to the target shooting mode has reached a threshold. If yes, execute step 209; otherwise, return to step 205.

Step 209: It is determined that the reliability of at least one component of each component corresponding to the target shooting mode in the image processing apparatus 20 cannot meet the requirement.

Specifically, the ideal image corresponding to the target shooting mode may be acquired by using a related calling algorithm or a query preset image database, and matching the actual image with the ideal image corresponding to the target shooting mode by using a related image matching algorithm or a model, It is determined that the image processing apparatus 20 is currently reliable when the actual image matches the ideal image corresponding to the target photographing mode.

It can be understood that when the actual image does not match the ideal image corresponding to the target shooting mode, the reliability of each component corresponding to the target shooting mode in the image processing apparatus 20 needs to be further determined. As a possible implementation manner, according to The target photographing mode corresponds to the number of matching failures to determine whether the components corresponding to the target photographing mode in the image processing apparatus 20 have lost reliability.

For example, if the threshold value is 5, when it is determined that the number of matching failures corresponding to the target shooting mode has reached 5 times, it can be determined that the reliability of at least one component of each component corresponding to the target shooting mode cannot meet the requirement.

Alternatively, it may be determined according to the ratio of the number of ideal image matches and the number of mismatches corresponding to the target image capturing mode among the number of tested times corresponding to the target shooting mode, for example, the number of times of the test corresponding to the target shooting mode is 10 times. If there is only one mismatch, it can be determined that each component corresponding to the target shooting mode in the image processing device 20 is reliable; for example, among the 10 times of the tested times corresponding to the target shooting mode, only 5 times do not match, and image processing can be determined. The components of the device 20 corresponding to the target imaging mode are not reliable.

It should be noted that after determining that the reliability of at least one component of each component corresponding to the target shooting mode cannot meet the requirements, the test may be further performed according to the test scheme, thereby further verifying the reliability of other components, or determining the components in the above components. The reliability of the specific component is no longer sufficient.

For example, if the target shooting mode is the structured light shooting mode, and the number of matching failures of the structural light shooting mode is determined to have reached the threshold, it can be determined that the reliability of the laser light 24, the laser camera 21, or the image processing component cannot meet the requirements. . According to the test scheme, it is determined that the next test mode is the RGB shooting mode. At this time, if the obtained actual image is consistent with the ideal image, it can be determined that the image processing component is still reliable, thereby indicating that the above-mentioned structural light shooting mode fails to be matched, possibly This is because the reliability of the laser lamp 24 is lowered, and the reliability of the laser camera 21 may be lowered. By analogy, the reliability of each component in the image processing apparatus 20 can be determined by sequentially performing tests of various shooting modes.

The image processing apparatus testing method of the embodiment first determines a preset testing scheme according to the usage scenario of the image processing apparatus 20, and then determines a current target shooting mode according to a preset testing scheme during the testing process, and then shoots according to the target. The mode adjusts the operating state of the light-emitting component and the camera, and further determines the reliability of the image processing device 20 according to the matching between the actual image corresponding to the target image capturing mode and the ideal image. Thereby, the reliability of the image processing apparatus 20 is tested by the actual use scenario of the analog image processing apparatus 20, and the test result is true and reliable.

In order to implement the above embodiment, the present application also proposes an image processing apparatus testing apparatus 100.
