So that the manner in which the features and aspects of the present invention can be understood in detail, a more particular description of the invention, briefly summarized above, may be had by reference to embodiments, some of which are illustrated in the appended drawings.
Example one
FIG. 1 is a first schematic flow chart illustrating an implementation of a control method according to an embodiment of the present invention; the method is applied to the electronic equipment; as shown in fig. 1, the method includes:
step 101: the method comprises the steps that electronic equipment obtains first image data, and a first light source is used for projecting the first image data;
in this embodiment, the electronic device may be a notebook computer; the mobile phone can also be a smart phone; of course, the electronic device may also be a wearable device, such as a smart watch, a smart bracelet, smart glasses, a smart headset, and other devices with data processing capability.
In practical applications, the first light source may specifically be a light source composed of three primary colors of RGB; that is, after the electronic device acquires the first image data, the first image data is projected by using the three primary colors of RGB as light sources. Referring to fig. 2, after the electronic device acquires the first image data, the first image data is projected by using a red light digital processing (DLP) device, a green light DLP device, and a blue light DLP device.
Step 102: acquiring preset image data, and projecting the acquired preset image data by using a second light source with wavelength parameters meeting preset conditions;
in this embodiment, the preset condition specifically indicates that the wavelength of the second light source is within a wavelength range corresponding to the invisible light; for example, the second light source may specifically characterize an infrared laser; that is to say, in this embodiment, the second light source representing the invisible light is used to project the preset image data, and then a detection image corresponding to the preset image data is projected, and for the observation of the user, the detection image is an image presented by the invisible light.
In practical application, the preset image data is preset image data according to actual requirements, for example, the preset image data may specifically be a dynamic Pattern, and the dynamic Pattern may specifically be a bitmap; in a specific embodiment, after the preset image data is obtained, the electronic device further needs to detect the preset image data to obtain a pixel feature of the preset image data, determine a first projection power matched with the preset image data according to the pixel feature of the preset image data, and project the obtained preset image data at the first projection power by using a second light source whose wavelength parameter meets a preset condition. That is to say, the electronic device may determine the projection power of the second light source according to the pixel characteristics of the preset image data, so as to lay a foundation for the identification process of the user operation in different environments and under different conditions.
Step 103: obtaining a target image corresponding to the first image data and a detection image corresponding to the preset image data; the projection power of the second light source corresponds to the preset image data;
in this embodiment, the correspondence between the projection power of the second light source and the preset image data may specifically be that the projection power of the second light source matches with a pixel feature of the preset image data.
Step 104: presenting the target image and the detection image in a first area outside the electronic device.
In this embodiment, the detection image represents an interactive projection interface capable of identifying user operations, and further, the preset image data is a dynamic Pattern, which may be specifically a bitmap; therefore, the detection image may also be a dynamic Pattern corresponding to the preset image data, such as a bitmap.
The embodiments of the present invention are explained in further detail below with reference to specific application scenarios:
FIG. 3 is a schematic diagram of a conventional laser micro-projection; as shown in fig. 3, in the laser micro projection, the conventional method utilizes MEMS to control the output of RGB three primary colors, and finally combines them into a colorful pattern; the fixed Pattern is generated by a Diffractive Optical Element (DOE), and here, because the Pattern is fixed, if the fixed Pattern can support short-distance user operation identification, when the distance between the interactive projection interface and the micro projector is increased, the user operation identification cannot be realized; further, if the fixed Pattern can support remote user operation identification, at this time, although the fixed Pattern supporting remote identification can obviously support short-range identification, the identification algorithm at this time is complex and high in power consumption, and it is difficult to integrate the identification algorithm with high power consumption on the mobile device; furthermore, if the remote and close identification is realized through different fixed Pattern patterns, a plurality of DOEs are needed, so that the cost is increased, and meanwhile, the layout design difficulty is increased because the DOE placement is closely related to the light path coverage; thus, the existing approaches limit the application of laser micro-projection to mobile devices.
FIG. 4 is a schematic diagram of a control method according to an embodiment of the present invention; as shown in fig. 4, in the control method according to the embodiment of the present invention, on the basis of the original RGB three primary colors, specifically, the first light source, an additional light source, that is, a second light source, for example, an infrared laser, is added, and the preset image data is projected by the second light source, specifically, the MEMS is used to perform time-sharing scanning on the first light source and the second light source, that is, the four light sources, so as to obtain the target image and the detection image, thereby laying a foundation for identifying the user operation by the detection image.
Furthermore, since the wavelength of the second light source is within the wavelength range of the invisible light, that is, the second light source is the invisible light, from the viewpoint of viewing by a user, it is obvious that projecting the preset image data by using the newly added second light source does not affect the display of the target image; furthermore, since the control method according to the embodiment of the present invention projects the preset image data through the second light source, the embodiment of the present invention can select the preset image data with different pixel characteristics according to the actually required user operation identification requirement (for example, a distance identification requirement), and further project the preset image data matched with the user operation identification requirement through the second light source to obtain a detection image, where the distance identification can be implemented by adjusting the pixel characteristics of the preset image data, so that the embodiment of the present invention can adopt different optimization algorithms according to the difference in the distance presented, and further achieve the purpose of saving power consumption; meanwhile, the method of the embodiment of the invention can be applied to the mobile equipment because the recognition algorithm can be optimized according to the difference of the presentation distance.
Specifically, the embodiment of the invention utilizes MEMS to control infrared laser to output different dynamic patterns, wherein when the dynamic patterns are arranged more distantly, the electronic equipment for realizing the control method can identify the user operation in a close range; when the dynamic Pattern lattice arrangement is dense, the electronic equipment for realizing the control method can identify remote user operation; in addition, in the embodiment of the invention, the first light source and the second light source can be well overlapped, that is, the presented target image and the presented detection image can be well overlapped, so that the identification accuracy is improved.
According to the control method provided by the embodiment of the invention, when the original first light source projects the first image data, the second light source is utilized to project the preset image data, and then the target image corresponding to the first image data and the detection image corresponding to the preset image data are presented in the first area outside the electronic equipment, so that the purpose of presenting the target image and presenting the detection image is realized, and a foundation is laid for identifying the user operation through the detection image.
Furthermore, since the detection image is displayed by projecting the preset image data by the second light source in the embodiment of the present invention, different preset image data can be selected according to the actually required user operation identification requirement (for example, a distance identification requirement), and then the preset image data matched with the user operation identification requirement is projected by the second light source to obtain the detection image; therefore, the control method provided by the embodiment of the invention can realize automatic adaptation of the distance, optimize the recognition algorithm and reduce the power consumption.
Example two
Based on the control method according to the first embodiment, after step 104, as shown in fig. 5, the control method further includes:
step 105: acquiring the detection image and user operation in the first area;
step 106: analyzing the user operation according to the acquired detection image;
step 107: and determining a control instruction according to the analysis result so as to control the electronic equipment to respond to the user operation.
In practical application, the electronic device may specifically acquire the detection image through an acquisition unit, and simultaneously acquire the user operation in the first area, so as to determine an operation characteristic of the user operation with respect to the detection image, for example, three-dimensional coordinate information corresponding to the detection image of the user operation, and generate a control instruction according to the three-dimensional coordinate information, so as to control the electronic device to respond to the user operation. Here, the analysis result may be three-dimensional coordinate information of the user operation with respect to the detection image.
EXAMPLE III
FIG. 6 is a third schematic flow chart illustrating an implementation of the control method according to the embodiment of the present invention; in the embodiment, the electronic equipment can select the preset image data matched with the preset presentation distance according to the preset presentation distance so as to present the detection image, so that the aim of pertinently selecting the preset image data is fulfilled, and a foundation is laid for simplifying the identification algorithm; specifically, as shown in fig. 6, the method includes:
step 601: the electronic equipment acquires a preset presentation distance between a detection image expected to be presented and the electronic equipment;
in this embodiment, the electronic device may be a notebook computer; the mobile phone can also be a smart phone; of course, the electronic device may also be a wearable device, such as a smart watch, a smart bracelet, smart glasses, a smart headset, and other devices with data processing capability.
In this embodiment, the process of obtaining the preset presentation distance may be obtaining the preset presentation distance through a user operation, for example, a user directly inputs a numerical value, and the electronic device sets the numerical value input by the user as the preset presentation distance; or, the electronic device may directly determine a preset presentation distance in a laser ranging manner, for example, when a user expects to project a detection image on a first screen that the electronic device is, at this time, the electronic device detects a distance between itself and the first screen in the laser ranging manner, and sets the preset presentation distance according to a detection result. Here, the embodiment does not limit the manner in which the electronic device obtains the preset presentation distance, and in practical applications, the electronic device may determine the preset presentation distance according to any existing detection manner.
Step 602: selecting preset image data from a preset image list according to a preset presentation distance; wherein the pixel characteristics of the preset image data are matched with the preset presentation distance;
in this embodiment, before step 601, the electronic device needs to set a preset image list, where preset image data with different pixel characteristics are stored in the preset image list, so that the electronic device can select the preset image data matched with the presentation distance according to the presentation distance.
In practical applications, the execution order of the steps 601 and 602 may be exchanged with that of the step 603, as long as the steps 601 and 602 are executed before the step 604.
Step 603: acquiring first image data, and projecting the first image data by using a first light source;
in practical applications, the first light source may specifically be a light source composed of three primary colors of RGB; that is, after the electronic device acquires the first image data, the first image data is projected by using the three primary colors of RGB as light sources. Referring to fig. 2, after the electronic device acquires the first image data, the first image data is projected by using a red light digital processing (DLP) device, a green light DLP device, and a blue light DLP device.
Step 604: acquiring preset image data, and projecting the acquired preset image data by using a second light source with wavelength parameters meeting preset conditions;
in this embodiment, the preset condition specifically indicates that the wavelength of the second light source is within a wavelength range corresponding to the invisible light; for example, the second light source may specifically characterize an infrared laser; that is to say, in this embodiment, the second light source representing the invisible light is used to project the preset image data, and then a detection image corresponding to the preset image data is projected, and for the observation of the user, the detection image is an image presented by the invisible light.
In practical application, the preset image data is preset image data according to actual requirements, for example, the preset image data may be a dynamic Pattern, and the dynamic Pattern may be a bitmap.
Further, in practical applications, the electronic device further needs to determine a second projection power according to the determined preset image data and the preset presentation distance; then, a second light source with wavelength parameters meeting preset conditions is used for projecting the acquired preset image data at the second projection power; therefore, the purpose of adjusting the pixel characteristics of the detection image by adjusting the projection power is achieved, and a foundation is laid for the identification process of user operation under different environments and different conditions.
Step 605: obtaining a target image corresponding to the first image data and a detection image corresponding to the preset image data; the projection power of the second light source corresponds to the preset image data;
in this embodiment, the correspondence between the projection power of the second light source and the preset image data may specifically be that the projection power of the second light source matches with a pixel feature of the preset image data.
Step 606: presenting the target image and the detection image in a first area outside the electronic device.
In this embodiment, the detection image represents an interactive projection interface capable of identifying user operations, and further, the preset image data is a dynamic Pattern, which may be specifically a bitmap; therefore, the detection image may also be a dynamic Pattern corresponding to the preset image data, such as a bitmap.
