[0028] Example implementations will now be described more fully with reference to the accompanying drawings. Example implementations may, however, be implemented in many different forms and should not be construed as limited to the implementations set forth herein; rather, these implementations are provided so that this disclosure will be thorough and complete, and will fully convey the scope of example implementations to those skilled in the art. The described features, structures, or characteristics can be combined in one or more implementations. In the following description, numerous specific details are provided, such as examples of programming, software modules, user selections, etc., to provide a thorough understanding of implementations of the application. One skilled in the relevant art will recognize, however, that the

[0029] Reference will be made to Figure 1 , Figure 1An application scenario diagram of a calibration method for laser interference according to an embodiment of the present application is shown schematically. As shown in Figure 1 To improve the image shooting effect, a laser focusing element 120 and a spectrum sensor 130 can be arranged in the terminal device 100 in addition to the camera 110; the laser focusing element 120 and the spectrum sensor 130 can be turned on at the same time, the laser focusing element 120 can determine the distance between the shooting object 140 and the camera 110 based on the corresponding laser emission range, and the spectrum sensor 130 can detect spectrum data based on the corresponding ambient light collection range, according to which the related parameters of the camera 110 can be adjusted so that the camera 110 can shoot images with more realistic colors.

[0030] However, as shown in Figure 1 The laser emission range and the ambient light collection range overlap, so the laser emitted by the laser focusing element 120 will be received by the infrared spectrum (IR) channel of the spectrum sensor 130 after being reflected by the shooting object 140, resulting in abnormal spectrum data detected by the spectrum sensor 130. If the spectrum sensor 130 reports abnormal ambient light information, it will cause the matching of incorrect camera 110 related parameters, resulting in color deviation in the picture.

[0031] Generally, the distance between the laser focusing element 120 and the spectrum sensor 130 can be adjusted so that there is no overlap between the laser emission range and the ambient light collection range, but this easily affects the detection accuracy of the laser focusing element 120 for the object distance. Alternatively, the emission intensity of the laser focusing element 120 can be reduced to reduce the interference of the reflected light on the spectrum data detected by the spectrum sensor 130, but this method can only alleviate the interference on the spectrum sensor 130, but cannot completely solve the problem.

[0032] The present application conceives a calibration method for laser interference, which can be specifically referred to Figure 2 , Figure 2 A flowchart of a calibration method for laser interference according to an embodiment of the present application is shown schematically. As shown in Figure 2 The method comprises the following steps.

[0033] Step S210: determining the laser energy at different focusing distances, the shooting distance relative to the shooting object, and the reflectivity corresponding to the shooting object.

[0034] Step S220: generating a laser energy value received by the spectrum channel according to the reflectivity, the shooting distance, and the laser energy.

[0035] Step S230: performing a laser interference calibration operation on the spectrum channel according to the laser energy value.

[0036] Implementations Figure 2 The method shown can determine accurate laser energy values based on laser energy at different focusing distances, reflectivity of the photographed object, and photographing distance, remove interference of the laser energy values on the spectral channel, and ensure accuracy of spectral data detected by the spectral sensor. In addition, the application can calculate the additional laser energy values received by the spectral channel based on the reflectivity, photographing distance, and laser energy, without the aid of external devices, thereby reducing the difficulty of obtaining the laser energy values. In addition, since the application can ensure the accuracy of the spectral data, the color authenticity of the image photographed based on the spectral data can be improved, and the picture color cast problem can be avoided.

[0037] Next, the above steps of the present example embodiment are described in more detail.

[0038] In step S210, the laser energy at different focusing distances, the photographing distance relative to the photographed object, and the reflectivity corresponding to the photographed object are determined.

[0039] Specifically, the laser energy refers to the laser energy reflected from the photographed object at different distances, which can be obtained by setting the emission power of the laser focusing element according to actual needs; the photographed object can be any object, which is not limited by the present embodiment, and the photographing distance relative to the photographed object represents the distance between the photographed object and the camera; and the reflectivity corresponding to the photographed object represents the case of the surface material of the photographed object reflecting laser.

[0040] As an optional embodiment, determining the laser energy at different focusing distances includes: in response to a calibration object moving operation, controlling the laser focusing element to emit laser and receive reflected light to obtain the laser energy corresponding to the current focusing distance until the laser energy at different focusing distances is obtained. In this way, multiple laser energies can be determined as reference data for laser interference calibration, which is beneficial to subsequent calculation of the laser energy values additionally received by the spectral channel based on the multiple laser energies, so as to achieve accurate laser interference calibration.

[0041] Specifically, the calibration object can be set and moved, and after each movement of the calibration object, the laser focusing element can be controlled to emit laser and receive reflected light, and the laser energy corresponding to the current focusing distance can be determined by the time interval between emission and reception, where the current focusing distance refers to the distance between the calibration object and the camera. In this way, the laser energy at multiple focusing distances can be obtained as reference data for laser interference calibration.

[0042] Please refer to Figure 3 , Figure 3 An example of a laser energy acquisition method according to an embodiment of the application is schematically shown. As shown in FIG. 2, the laser energy acquisition method includes the following steps. Figure 3As shown, a completely dark environment can be set, and a slide rail 310 can be set in the shooting range of the terminal 300, and a movable calibration object 320 can be set on the slide rail 310. The calibration object 320 can slide at any distance on the slide rail 310. For example, the calibration object 320 can be at a position 321, a position 322, a position 323, and the like, which are not limited by the embodiments of the present application. Optionally, the calibration object 320 can slide in the direction shown in the figure. Whenever the calibration object 320 slides, the laser focusing element can emit laser and receive reflected light in response to the calibration object moving operation, so as to obtain the laser energy corresponding to the current focusing distance. Accordingly, the laser energy under different focusing distances can be obtained, which can be represented in any form such as a numerical value, a character, a symbol, and the like, which are not limited by the embodiments of the present application. Figure 3

[0043] In addition, optionally, the material of the calibration object 320 can be changed and the above steps can be repeated to obtain a set of laser energies corresponding to different materials, and each set of laser energies includes laser energies under different focusing distances. Based on this, the laser energy value received by the spectral channel according to the reflectivity, the shooting distance and the laser energy is generated, including: determining a target laser energy set corresponding to the shooting object from the laser energy set of different materials according to the material of the shooting object; and generating the laser energy value received by the spectral channel according to the reflectivity, the shooting distance and the target laser energy set.

[0044] As an optional embodiment, the reflectivity corresponding to the shooting object is determined, including: controlling the illumination lamp to be turned on to collect first spectral data, and controlling the illumination lamp to be turned off to collect second spectral data; and determining the reflectivity corresponding to the shooting object based on the first spectral data and the second spectral data. In this way, the reflectivity corresponding to the shooting object can be determined only according to the illumination lamp, without the aid of external devices, which can improve the determination efficiency of the reflectivity and is conducive to more efficiently determining the laser energy value received by the spectral channel.

[0045] Specifically, the illumination lamp can be a wide-spectrum LED lamp in a preset wavelength range (e.g., 3500 nm-1000 nm). Spectrum is a pattern of monochromatic light arranged in order according to wavelength (or frequency) after dispersion of a complex light by a dispersion system (e.g., a prism, a grating). The full name is optical spectrum. The visible spectrum in the spectrum is a part of the electromagnetic spectrum visible to the human eye. Electromagnetic radiation in the wavelength range of the visible spectrum is called visible light.

[0046] ​In addition, the first spectrum data and the second spectrum data are different in that the first spectrum data comprises ambient light data and reflected light data, and the second spectrum data comprises ambient light data. Based on this, determining the reflectivity corresponding to the photographed object based on the first spectrum data and the second spectrum data comprises: subtracting the first spectrum data from the second spectrum data to obtain a difference value, and then calculating the reflectivity corresponding to the photographed object based on the difference value and the spectrum corresponding to the illuminating lamp.

[0047] As an optional embodiment, determining the photographing distance relative to the photographed object comprises: triggering the laser focusing element to emit laser and receive reflected light to obtain the photographing distance relative to the photographed object. In this way, the photographing distance relative to the photographed object can be determined, so as to facilitate subsequent calculation of the accurate laser energy value received by the spectrum channel.

[0048] Specifically, the time difference between the emission of laser and the reception of reflected light determines the photographing distance relative to the photographed object.

[0049] As an optional embodiment, it further comprises: determining the motor focusing position according to the photographing distance; and controlling the motor to adjust to the motor focusing position. In this way, the motor can be adjusted to the focusing position in time according to the photographing distance, so as to improve the subsequent shooting quality.

[0050] Specifically, the motor focusing position required for a clear image can be determined according to the photographing distance, and the motor focusing position refers to the target position at which the motor should be located.

[0051] In addition, it further comprises: synchronously starting the laser focusing element and the spectrum sensor in response to the starting operation; and emitting laser by the laser focusing element; wherein the spectrum sensor is configured to acquire the first spectrum data and the second spectrum data.

[0052] In step S220, the laser energy value received by the spectrum channel is generated according to the reflectivity, the photographing distance and the laser energy.

[0053] Specifically, the laser energy value can be understood as the energy value corresponding to the additional infrared spectrum received by the spectrum channel.

[0054] As an optional embodiment, generating the laser energy value received by the spectrum channel according to the reflectivity, the photographing distance and the laser energy comprises: determining a target laser energy corresponding to the photographing distance from the laser energy under different focusing distances; and generating the laser energy value received by the spectrum channel under the photographing distance based on the reflectivity, the photographing distance and the target laser energy. In this way, the calculation of the laser energy value received by the spectrum channel can be realized without setting the frame rate and the spectrum integration time, so as to accurately implement the laser interference calibration operation.

[0055] Specifically, the reflectivity, the shooting distance, and the target laser energy can be substituted into the expression: laser energy value = reflectivity * shooting distance * target laser energy + target laser energy to calculate the laser energy value received by the spectral channel at the shooting distance.

[0056] In step S230, a laser interference calibration operation is performed on the spectral channel according to the laser energy value.

[0057] Specifically, the laser interference calibration operation can act on the ambient light information obtained by the spectral channel, and specifically, the laser energy value in the infrared spectrum of the ambient light information can be removed.

[0058] As an optional embodiment, the method further includes: matching corresponding image adaptive parameters based on the spectral data of the spectral channel after laser interference calibration; and configuring the image adaptive parameters for the camera. In this way, image shooting based on appropriate image adaptive parameters can be implemented, which is beneficial to obtaining images with true colors and improving image display effects.

[0059] Specifically, the image adaptive parameters can include one or more shooting-related parameters, such as an Auto White Balance (AWB) parameter, which is not limited in the embodiments of the present application.

[0060] Referring to Figure 4 , Figure 4 A flowchart of a calibration method for laser interference according to another embodiment of the present application is schematically shown. As Figure 4 shown, the calibration method for laser interference includes steps S400-S414.

[0061] Step S400: In response to a calibration object moving operation, the laser focusing element is controlled to emit laser and receive reflected light to obtain laser energy corresponding to a current focusing distance, and the above steps are repeated until laser energy at different focusing distances is obtained.

[0062] Step S402: The laser focusing element is triggered to emit laser and receive reflected light to obtain a shooting distance relative to a shooting object.

[0063] Step S404: The lighting lamp is controlled to be turned on to collect first spectral data, and the lighting lamp is controlled to be turned off to collect second spectral data, and then the reflectivity corresponding to the shooting object is determined based on the first spectral data and the second spectral data.

[0064] Step S406: The motor focusing position is determined according to the shooting distance, and the motor is controlled to be adjusted to the motor focusing position.

[0065] Step S408: The target laser energy corresponding to the shooting distance is determined from the laser energy at different focusing distances.

[0066] Step S410: generating a laser energy value received by the spectral channel at the shooting distance based on the reflectivity, the shooting distance, and the target laser energy.

[0067] Step S412: performing a laser interference calibration operation on the spectral channel according to the laser energy value.

[0068] Step S414: matching corresponding image adaptive parameters based on spectral data of the spectral channel after the laser interference calibration, and configuring the image adaptive parameters for the camera.

[0069] It should be noted that steps S400-S414 correspond to the steps and embodiments shown in Figure 2 For specific implementations of steps S400-S414, please refer to the steps and embodiments shown in Figure 2 For specific implementations of steps S400-S414, please refer to the steps and embodiments shown in

[0070] As can be seen, by implementing the method shown in Figure 4 , the precise laser energy value can be determined based on the laser energy at different focusing distances, the reflectivity of the shooting object, and the shooting distance, the interference of the laser energy value on the spectral channel can be removed, and the accuracy of the spectral data detected by the spectral sensor can be ensured. In addition, since the present application can calculate the additional laser energy value received by the spectral channel based on the reflectivity, the shooting distance, and the laser energy, without the aid of external equipment, the difficulty of obtaining the laser energy value can be reduced. In addition, since the present application can ensure the accuracy of the spectral data, the color authenticity of the image taken based on the spectral data can be improved, and the picture color deviation problem can be avoided.
