S201, reading position information and view angle information of a shooting unit in a video display table, and determining a shooting area according to the position information and the angle information.
S202, acquiring a light supplementing range supported by a light supplementing unit, and determining the setting height and the light supplementing angle of the light supplementing unit according to the light supplementing range and the shooting area.
S203, sending an opening instruction to the light supplementing unit, and enabling the light supplementing unit to supplement light to the shooting area according to the set height and the light supplementing angle.
S204, acquiring brightness information of the desktop video.
In one embodiment, the brightness information may be used to represent the brightness level in the shooting environment when the desktop video is shot. The luminance information may include light intensity, direction of light, and the like. The desktop video is shot by a shooting unit, and specifically, the object on the video display platform is put on the screen through a camera in the shooting unit. The brightness information of the desktop video can be obtained through a wireless network, and the brightness can be represented by specific numerical values. In this embodiment, after the light supplementing unit adjusts the corresponding setting height and the light supplementing angle, light supplementing is performed on the shooting area, and whether the light supplementing condition is satisfied is identified for the internal brightness information of the shot desktop image. If the light supplementing condition is not met, further adjustment of the light supplementing requirement is needed. The light supplementing condition may be that when the average brightness in the shooting area is within a preset threshold range, it is determined that the light supplementing condition is satisfied, and dimming is not required. Otherwise, if the average brightness in the shooting area is not within the preset threshold range, it is determined that the light supplementing condition is not met, and dimming operation is needed. For example, the average light intensity threshold is set to be 200lx-500lx, if the intensity of the light supplement unit after the height and angle of the light supplement unit are adjusted is 300lx, the light intensity value is within the preset average light intensity range, so that the best shooting effect can be achieved, and the light supplement adjustment is not needed. If the intensity of the light supplementing unit is 1000lx after the height and the angle of the light supplementing unit are adjusted, the illumination intensity is strong at the moment, the exposure phenomenon is easy to generate, the display effect is affected, and the light supplementing intensity needs to be further adjusted.
S205, determining a light supplementing intensity adjusting instruction according to the brightness information.
In this embodiment, the compensation light intensity adjustment instruction may be an instruction for adjusting the intensity of light. Specifically, after the brightness information is determined, if the average brightness in the brightness information is smaller than the preset threshold range, it may be determined that the instruction for increasing the light intensity is issued. If the average brightness in the brightness information is greater than the preset threshold range, the instruction of reducing the light intensity can be determined to be sent.
S206, sending the light supplementing intensity adjusting instruction to the light supplementing unit so as to adjust the brightness of the light supplementing unit.
In this embodiment, if it is determined that the light intensity needs to be reduced according to the brightness information, an instruction for reducing the light intensity is sent to the light supplementing unit, and after the light supplementing unit receives the instruction, the intensity of the light supplementing is correspondingly reduced. Otherwise, if the light intensity needs to be increased according to the brightness information, an instruction for increasing the light intensity is sent to the light supplementing unit, and after the light supplementing unit receives the instruction, the light supplementing intensity is correspondingly increased.
In this embodiment, brightness information of desktop video shooting is obtained; determining a light supplementing intensity adjusting instruction according to the brightness information; sending the light supplementing intensity adjusting instruction to the light supplementing unit so as to adjust the brightness of the light supplementing unit; the device is beneficial to adjusting according to actual shooting conditions, obtains optimal shooting brightness, and further improves the display effect.
Example III
Fig. 5 is a flowchart of a method for determining a light intensity adjustment instruction according to a third embodiment of the present application; as shown in fig. 5, the method specifically comprises the following steps:
s301, reading position information and view angle information of a shooting unit in a video display table, and determining a shooting area according to the position information and the angle information.
S302, acquiring a light supplementing range supported by a light supplementing unit, and determining the setting height and the light supplementing angle of the light supplementing unit according to the light supplementing range and the shooting area.
S303, sending an opening instruction to the light supplementing unit, and enabling the light supplementing unit to supplement light to the shooting area according to the set height and the light supplementing angle.
S304, acquiring brightness information of desktop video shooting.
S305, identifying the brightness values of at least two brightness partitions according to the brightness information.
In this embodiment, the brightness partition may be a brightness partition caused by uneven distribution of illumination intensity on the video display stand due to different directions of light in the environment. Since the two luminance partitions are subjected to different illumination intensities, the luminance values of the two luminance partitions are different. In this embodiment, luminance information of a captured desktop video is obtained, a luminance value is extracted from the luminance information, and different luminance partitions are divided according to the magnitude of the luminance value.
S306, determining whether the brightness value of each brightness partition meets the adjustment condition.
In this embodiment, the adjustment condition may be that there is a large difference between the luminance value in the photographing region and the optimal luminance value, which affects the photographing effect. Specifically, an optimal luminance value may be determined according to the luminance value of the history shooting environment, and stored. After the brightness values of all the brightness partitions are determined, searching the optimal historical brightness values similar to the environment through a network, judging whether the difference value between the brightness values of all the partitions and the optimal historical brightness values is larger than or smaller than a brightness difference threshold value, and if not, meeting the regulation conditions. Otherwise, the adjustment condition is not satisfied. For example, if the historical optimum luminance value is 5×10 3 cd, the luminance difference threshold is 1×10 3 cd, and if the luminance value of the first luminance partition is 4.5×10 3 cd, the luminance value of the second luminance partition is 7×10 3 cd. Therefore, the difference between the luminance value of the first luminance partition and the historical optimal luminance value is less than 1×10 3 cd, and the adjustment condition is not satisfied. The difference between the luminance value of the second luminance partition and the historical optimal luminance value is greater than 1×10 3 cd, and the adjustment condition is considered to be satisfied.
And S307, if yes, generating a light compensation intensity adjusting instruction corresponding to each brightness partition.
In this embodiment, if the brightness values of the brightness partitions all meet the above adjustment conditions, different light intensity compensation adjustment instructions are generated for different brightness values. Specifically, when the brightness value of the first brightness partition meets the adjustment condition, it is further determined whether the brightness value in the brightness partition is greater than the historical optimal brightness value. The luminance value of the luminance partition is greater than the historical optimal luminance value and then a decrease light intensity command is generated. The luminance value of the luminance partition is less than the historical optimal luminance value, and an instruction for increasing the light intensity is generated.
And S308, sending the light supplementing intensity adjusting instruction to the light supplementing unit so as to adjust the input current of at least two light supplementing lamps in the light supplementing unit.
In this embodiment, the light-compensating lamp may be a lamp for compensating light. A plurality of light supplementing lamps can be arranged on the telescopic rod side by side. And after each brightness partition generates a corresponding adjusting instruction, sending the adjusting instructions to the light supplementing unit. And after receiving the corresponding adjusting instruction of each brightness partition, the light supplementing unit inputs current to at least two light emitters contained in each brightness partition and is used for starting the light supplementing lamp to adjust the brightness of the brightness partition.
