All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without any creative effort belong to the protection scope of the present application.

The core of the application is to provide a projection device, a method, a device, a robot and a medium.

In order that those skilled in the art will better understand the disclosure, the following detailed description will be given with reference to the accompanying drawings.

The projection device mentioned in the application comprises a memory and a processor, wherein the memory stores computer readable instructions, and the processor executes the computer readable instructions to realize a projection method. The projection equipment that this application provided generally installs on the robot, and the robot is used for places such as market, KTV usually, and projection equipment on the robot can be to emitting light beam on ground or the screen to through the projection pattern of galvanometer. The projection device comprises a plurality of light emitting sources, which can be Light Emitting Diodes (LEDs), laser diodes or lasers; the general luminous sources are three, the light of three colors of red, green and blue is combined into a composite light beam, the color of the composite light is not required, and the current projection equipment supports 64 colors. When the brightness value of the synthesized light is adjusted, the brightness values of the three light-emitting sources are adjusted, but since the synthesized light is a combination of the lights of the three light-emitting sources, when the brightness values of the three light-emitting sources are adjusted, there is a high possibility that the color of the finally obtained synthesized light is changed due to incorrect adjustment ratios of the brightness values of the three light-emitting sources. Therefore, the present application provides a solution, and fig. 1 is a flowchart of a projection method provided in an embodiment of the present application, and as shown in fig. 1, the method includes the following steps:

s10: acquiring an adjustment request;

the method comprises the steps of firstly obtaining an adjustment request for adjusting the projection equipment, wherein the adjustment request can be sent by a target object according to actual requirements, or can be automatically triggered after the projection equipment obtains the ambient brightness through a photosensitive sensor. For example, the robot may have a control screen, and the target object may send an adjustment request to the projection device through the control screen.

S11: selecting an instruction corresponding to a brightness gear in a memory according to an adjustment request, wherein the memory stores the instructions of a plurality of brightness gears, different brightness gears correspond to the synthetic lights with different brightness values, and the colors of the synthetic lights under different brightness gears are the same;

the adjustment request is to adjust the brightness gear of the projection device, the number of the brightness gear of the projection device is not limited, and the brightness gear can be set to 5 gears, and the gears correspond to different brightness values respectively. If there are three light sources, each light source has a corresponding brightness value under 5 brightness levels, the combined light also has 5 different brightness values. When the brightness values of the three light-emitting sources are set, the brightness values of the three light-emitting sources are roughly adjusted to correspond to the brightness values of 5 brightness gears, the brightness values of the three light-emitting sources under each brightness gear are finely adjusted after the brightness values are set, the brightness values of the three light-emitting sources do not need to be the same, the fine adjustment aims to ensure that the colors of the synthetic lights in different brightness gears are the same, finally, the adjusted parameters are stored in a memory, and only corresponding instructions of the brightness gears need to be acquired in the memory when the brightness values are adjusted.

S12: and adjusting the brightness value of each luminous source according to the selected brightness gear.

And selecting the instruction of the brightness gear from the memory, namely extracting the parameters of the three luminous sources, and adjusting each luminous source according to the parameters to obtain the synthetic light with the target brightness value.

The projection device provided by the embodiment of the application comprises a memory, a processor and a plurality of light-emitting sources, wherein the plurality of light-emitting sources can emit light with different colors to form synthetic light, the memory stores instructions of a plurality of brightness gears, the brightness values of the light-emitting sources under different brightness gears are different, namely, the brightness values of the synthetic light corresponding to different brightness gears are also different, and the colors of the synthetic light consisting of the light beams of the light-emitting sources under different brightness gears are the same. The processor, when executing the computer readable instructions in the memory, performs the steps of: acquiring an adjusting request for adjusting the projection equipment; selecting a corresponding brightness gear in the memory according to the adjustment request; the brightness value of each luminous source is adjusted according to the selected brightness gear to achieve the effect of controlling the brightness value of the synthesized light. The projection equipment provided by the application can emit different brightness values but the same color of synthetic light under different gears, so that the synthetic light with the correct color can be obtained when the brightness of the synthetic light is adjusted.

In practical applications, the brightness value of the light-emitting sources can be adjusted in various ways, namely, the brightness value of the synthesized light emitted by the projection device is adjusted by controlling the PWM value of each light-emitting source. And secondly, the brightness value of the synthesized light emitted by the projection equipment is adjusted by controlling the voltage of the luminous source. The brightness value of the luminous source can be conveniently adjusted through the PWM value, the voltage in the circuit does not need to be changed, but the luminous source can emit intermittent light which can not be perceived by the human eyes. If the brightness value of the synthesized light emitted by the projection device can be adjusted accurately by controlling the voltage of the light-emitting source, the light-emitting source will emit continuous light, but this approach requires additional equipment to change the power supply voltage of the light-emitting source.

In the above embodiment, it is mentioned that obtaining the adjustment request for adjusting the projection device may be obtaining an adjustment request sent by the target object according to actual requirements, but this method is not very convenient and requires manual adjustment of the target object, so a photosensitive sensor may be further added to the projection device, and the photosensitive sensor is used to obtain the current ambient brightness, obtain a corresponding adjustment request according to the obtained ambient brightness, and adjust the brightness value of the projection device. By adopting the mode, the projection equipment can adaptively change the brightness value of the emitted synthetic light according to the environment brightness, and can bring better experience to the target object. In addition, if the acquired ambient brightness exceeds the threshold, the image projected under the current ambient brightness is represented to be invisible, so that the projection equipment is controlled to be closed to avoid long-term opening of the projection equipment and reduce the service life, and the threshold of the ambient brightness is not limited, which is based on the actual situation.

When adjusting the brightness value of the projection device, the brightness requirements of different target objects are different, so obtaining the adjustment request for adjusting the projection device includes: and acquiring an adjustment request of the target object to the projection equipment through the control screen. The projection equipment is installed on the robot body, the robot body comprises a control screen, the control screen can be installed on the head of the robot, operation of a target object is facilitated, and better use experience is provided for the target object.
