The step S10 includes: detecting indoor illumination intensity through a first sensor to obtain indoor environment light intensity; judging whether the indoor environment light intensity is larger than a preset light intensity threshold value, if the indoor environment light intensity is larger than the preset light intensity threshold value, judging that the projection effect of the projector system can be influenced due to the fact that the indoor environment light intensity is too high, and detecting the outdoor illumination intensity through a second sensor to obtain the outdoor environment light intensity.
And step S20, according to the difference between the outdoor environment light intensity and the indoor environment light intensity, the projection output light intensity of the projection host, the curtain and the lamp output light intensity of the indoor lamp are adjusted in a coordinated manner until the screen receiving light intensity of the projection screen meets the preset projection display condition.

Step S23, if the indoor environment light intensity is not greater than the outdoor environment light intensity, closing the curtain and re-detecting the indoor environment light intensity;
As an example, step S23 includes: if the indoor environment light intensity is not greater than the outdoor environment light intensity, the influence of the lamp output light intensity of the indoor lamp on the indoor environment light intensity is smaller than the influence of the outdoor environment light intensity on the indoor environment light intensity, and then the curtain is closed, so that the influence of the outdoor environment light intensity on the indoor environment light intensity is eliminated, and the indoor environment light intensity after the curtain is closed is re-detected through the first sensor.
And step S24, adjusting the projection output light intensity of the projection host and the light intensity output by the lamp until the screen receiving light intensity of the projection screen relative to the indoor environment light intensity and the projection output light intensity meets the preset projection display condition.

In the embodiment of the application, when the light intensity of the indoor environment is too high to influence the projection effect of the projector system, whether the light intensity of the outdoor environment or the light intensity output by the lamp is judged to be the main influencing factor influencing the light intensity of the indoor environment, if the light intensity output by the lamp is the light intensity output by the lamp, the light intensity output by the lamp of the indoor lamp is regulated downwards, and if the light intensity of the indoor environment is the light intensity of the outdoor environment, the curtain is closed, so that the rough regulation on the light intensity of the indoor environment is realized; furthermore, the projection output light intensity of the projection host and the light intensity output by the lamps are subjected to iterative adjustment, and the screen receiving light intensity is detected in real time, so that the indoor environment light intensity can be continuously adjusted until the indoor environment light intensity is optimal, namely, the screen receiving light intensity meets the preset projection display condition, thereby realizing the fine adjustment of the indoor environment light intensity.
Wherein, the adjusting the projection output light intensity of the projection host and the output light intensity of the lamp to finely adjust the indoor environment light intensity includes:
step S241, the detection light beam corresponding to the projection output light intensity is emitted to the projection screen through the projection host;
Step S242, detecting the screen received light intensity of the projection screen relative to the light intensity of the probe beam and the indoor environment;

Step S244, if not, the projection output light intensity and the lamp output light intensity are adjusted cooperatively, and the execution step is returned: and transmitting the detection light beam corresponding to the projection output light intensity to the projection screen through the projection host.
As an example, step S241 to step S244 include: transmitting a detection light beam to the projection screen through the projection host, wherein the light intensity of the detection light beam is the projection output light intensity; detecting screen received light intensity of the projection screen under both the detection light beam and the indoor environment light intensity; judging whether the received light intensity of the screen meets the preset projection display condition or not, and if the received light intensity of the screen meets the preset projection display condition, judging that the projector system meets the preset projection effect; if the received light intensity of the screen does not meet the preset projection display condition, judging that the projector system does not meet the preset projection effect, adjusting the projection output light intensity and the lamp output light intensity in a cooperative manner according to the received light intensity of the screen, and returning to the execution step: and transmitting the detection light beam corresponding to the projection output light intensity to the projection screen through the projection host. The purpose of the cooperative adjustment is to ensure that the screen receiving light intensity obtained according to the projection output light intensity and the lamp output light intensity is kept within a preset receiving light intensity range, and the projection output light intensity and the lamp output light intensity meet a preset size relationship, for example, the projection output light intensity can be larger than the lamp output light intensity, the projection output light intensity can be larger than 2 times of the lamp output light intensity, and the like.
The step of judging whether the screen received light intensity meets the preset projection display condition comprises the following steps:
Step A10, calculating the light intensity ratio between the received light intensity of the first screen and the received light intensity of the second screen, and calculating the light intensity sum value between the received light intensity of the first screen and the received light intensity of the second screen;
And step A20, if the light intensity ratio is within a preset light intensity ratio range and the light intensity sum value is within a preset light intensity sum value range, judging that the received light intensity of the screen meets the preset projection display condition.
In this embodiment, it should be noted that the received light intensity of the first screen is the received light intensity of the projection screen relative to the probe beam, and the received light intensity of the second screen is the received light intensity of the projection screen relative to the indoor environment. By controlling the light intensity and the light intensity within the preset light intensity and light intensity range, the screen receiving light intensity can be ensured not to be too large or too small, so that the projection effect of the projector system is ensured; the light intensity ratio is controlled within the range of the preset light intensity ratio, so that the light intensity of the indoor environment can be ensured not to influence the projection effect of the projector system, and the projection effect of the projector system is ensured. Therefore, in the embodiment of the application, the influence of factors of the whole intensity of the received light of the screen and the intensity of the indoor environment relative to the intensity of the projected output light on the projection effect is avoided, and the projection effect of the projector system is improved.
As an example, the first screen received light intensity and the second screen received light intensity are collected as follows: detecting the received light intensity of the second screen by a third sensor before the detection light beam is emitted to the projection screen by the projection host; transmitting a detection light beam to a projection screen through a projection host, and detecting the received light intensity of the comprehensive screen through a third sensor; and calculating the difference between the integrated screen received light intensity and the second screen received light intensity to obtain the first screen received light intensity.
Compared with the technical means that a plurality of lamps are usually arranged in front of a projection screen in the prior art, and then the quantity of lamps is controlled to be started manually to control the light intensity of the environment, the embodiment of the application firstly usually installs a plurality of lamps in front of the projection screen, and then the quantity of lamps is controlled to be started manually to control the light intensity of the environment, the difference between the outdoor environment light intensity and the indoor environment light intensity is controlled, the projection output light intensity of the projection host, the curtain and the light intensity of the lamps output by the indoor lamps are cooperatively regulated until the screen received light intensity of the projection screen meets the preset projection display condition, namely, when the projection effect is influenced by the strong outdoor environment light intensity, the projection output light intensity of the projection host and the light intensity output by the lamps of the indoor lamps are quantitatively regulated, and the window curtain are correspondingly regulated, so that the preset projection effect of the projection system can be controlled, the projection effect is achieved by the projection system, the quantity of the projection screen is controlled by the quantitative control of the projector, and the projection effect is further overcome by the projector, and the technical defect that the projection effect is accurately controlled by the quantity of the projector is realized when the projection effect is controlled by the projector.
