In an embodiment of the present invention, as shown in fig. 1, a method for supplementing light based on an auxiliary light source includes:
s100, acquiring a starting instruction, and starting a light source according to the starting instruction;
specifically, when the user learns that the ambient light is dark, the user needs to turn on the desk lamp to illuminate, and then sends a turn-on instruction to the desk lamp. After the desk lamp obtains the starting instruction, the lamp source of the desk lamp is started, and a light source is provided for the user to learn.
The mode that the desk lamp acquireed the instruction is diversified, and comparatively traditional mode has the control to open the device that closes the light source on for the desk lamp body, can be the form of button, also can be the form of touch. Secondly, a voice control mode may also be adopted, for example, when the user says "turn on the desk lamp", and when the desk lamp detects keywords such as "turn on", "desk lamp", etc., it is equivalent to acquiring a turn-on instruction. In addition, the sensing control mode can be similar to sensing a faucet capable of automatically discharging water, and when a user places a handle or other objects in the sensing area and the desk lamp senses the existence of the user, the lamp source is turned on.
In addition, the light intensity levels required after the light source is turned on are different due to the different light intensities of the external environments. The external desk lamp that has the device of control on-off lamp source on the body can set up different gears and correspond different light intensity levels, and the user can self manual adjustment. Also can dispose light intensity inductor by the desk lamp, according to the external environment light intensity that senses, combine external environment light intensity and the corresponding mapping table of lamp source light intensity, select suitable lamp source light intensity.
S200, obtaining a user picture after a light source is turned on;
specifically, after the lamp source of the desk lamp is turned on, the camera is synchronously turned on to obtain the user picture. The camera can be arranged at any position of the desk lamp, but because the shadow in the picture of the user needs to be identified later, the position where the camera is arranged relative to the light source should be selected to be low, and the closer the camera is to the desktop of the user during learning, the better the camera is.
S300, when the shadow exists in the user picture, calculating the shadow angle of the shadow;
specifically, when the shadow exists in the user picture obtained by recognition, it is shown that the region is shielded by the user or other objects, and enough light is not provided for the user to check and learn, so that the user needs to adjust the sitting posture to look down, on one hand, the sitting posture is incorrect, the spine is affected, and on the other hand, the eyes are too close to the desktop, and the influence on the eyesight is bad.
Therefore, the shadow angle of the shadow in the user picture is calculated by combining the position relation of the lamp source, the camera and the shielding object, so that the light intensity of the shielded part is judged, and in the same user picture, the farther the shadow area is away from the edge of the shielding object, the smaller the shadow angle is, and the weaker the light intensity is.
For example, when the light source is above the head of the user, the head of the user can shield part of light to form a shadow area, that is, the user is a shield, the edge of the shield is determined according to the position of the light source, and the shadow angle formed by combining the position of the camera and the edge of the shield at each point in the shadow area is determined.
S400, calculating the brightness level of the auxiliary lamp source light bead on the side surface of the desk lamp base according to the shadow angle;
specifically, the calculated different shadow angles correspond to different luminances, and if light supplement is required, the light supplement requirement is higher for a region with lower luminance corresponding to the shadow angle than for a region with higher luminance. Therefore, the side surface of the base of the desk lamp is provided with the auxiliary lamp source light beads, and the number of the auxiliary lamp source light beads can be only one or multiple, wherein the multiple auxiliary lamp source light beads can be continuously and densely distributed, and can also be regularly arranged at intervals. And then determining the brightness level of the auxiliary lamp source light bead on the side surface of the desk lamp base according to the shadow angle.
The corresponding mapping table of the shadow angle and the brightness level of the corresponding auxiliary lamp source light bead can be preset, and then the brightness level of the corresponding auxiliary lamp source light bead is determined according to the shadow angle by combining the mapping table. The establishing mode of the mapping table can be obtained according to the analysis of big data, and a proper mapping relation can be selected according to the use feeling of a user.
S500, adjusting the auxiliary lamp source light beads according to the brightness level.
Specifically, the corresponding auxiliary light source light beads are adjusted according to the determined brightness level, and the light rays emitted by the auxiliary light source light beads can eliminate the shadow on the learning desktop of the user. And after adjusting the light beads of the auxiliary light source, acquiring a new user picture again, and judging whether the new user picture has shadows. If not, the auxiliary light source light bead adjustment scheme is proper, and no adjustment is needed. If the shadow exists, which indicates that the auxiliary lamp source light bead adjusting scheme is not suitable, the brightness level of the auxiliary lamp source light bead can be adjusted until no shadow exists, and the brightness level of the auxiliary lamp source light bead in the final adjusting scheme is stored as the preferable adjusting scheme for the subsequent occurrence of the same situation.
