Detailed Description
In order to more clearly describe the present invention, the present invention will be further described with reference to the accompanying drawings.
In the following description, details of general examples are given to provide a more thorough understanding of the present invention. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. It should be understood that the specific embodiments are illustrative of the invention and are not to be construed as limiting the invention.
It will be understood that the terms "comprises" and/or "comprising," when used in this specification, specify the presence of stated features, integers, steps, operations, elements, or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, or groups thereof.
In the prior art, the eye protection mode of the projector mostly adopts the face recognition to the projection range so as to control the eye protection mode to be started, but the scheme is often inaccurate for recognition, because the portrait appears in the projection content, the simple portrait identification is easy to misjudge, and for the young, not necessarily looking directly at the light source, but slowly approaching the light source during travel, but for curiosity looking at the light source, although no direct strong light is emitted to the eyes of the infant, the intensity of the light source is far higher than that of the surrounding area, which easily causes dizziness to the infant, in this scene, the light firstly enters the shielding area, not the face, but the arm, therefore, in order to take such a scenario into consideration, the judgment standard in the prior art is easy to ignore the action characteristics of the infant, so a scheme for accurately identifying and protecting the action characteristics of the infant is required; meanwhile, the prior art only pays attention to the fact that if a barrier is identified and correspondingly closed, but the use experience of a projector as projection equipment is omitted, namely, a projection light source is usually required to be preheated after being closed and restarted, the light source is only used for projection, and continuous playing of content is not limited, so that the played content is not closed after the light source is closed, but in continuous playing, a user knows that some pictures and content of projection are missed when the projector is completely restarted, and very poor experience is brought to the user; based on the above, a need exists for a projector that has accurate identification and can realize different eye protection strategies for different playing contents so as to give consideration to the use experience of the projector; the specific scheme is as follows.
The invention provides a projector for accurately identifying shielding and starting protection, referring to fig. 1, comprising:
the projection apparatus 1 modulates light emitted from a light source and projects the modulated light within a predetermined range.
The detector 2 is arranged adjacent to the light source and is used for acquiring the area of a shelter in a preset projection range of the projection device; when the area of the shielding object exceeds a first threshold value, the projection device enters an eye protection state; the area of the shielding object can be the absolute area of the shielding object, and the judgment according to the area is that at least the head is in a preset range when human eyes directly irradiate a light source, so that the area judgment mode can accurately control the starting condition of the eye protection state.
The playing content control module 3 is electrically connected with the projection device 1 and is used for acquiring a playing data stream when the projection device enters an eye protection state, when the playing data stream is a video stream, the playing content control module sends a pause instruction, and the projection device closes a light source according to the pause instruction and pauses the video stream; then, the projection apparatus may have a networking function, or may be in a form of being externally connected to a playback source, and in any form, when the projection apparatus is converted into the optical projection system through the central processing module, the central processing module may have a data stream of the playback source file to pass through, and in this way, what form the playback content is at this time can be known, which is common: video playing, PPT playing, picture playing, webpage interface releasing and the like; the data stream type during video playing is a video stream, PPT and pictures are static picture streams, the three types of playing can be independently played by a projector system, a webpage interface is always in a pure static display state, and response can be carried out only through manual operation; therefore, for the first three playing modes, the content is played independently when the light source is turned off, so that the user can have very bad playing experience because only the light source is turned off and the playing content is not processed, which is also a disadvantage in the prior art; in the scheme, the playing content control module is used for judging the type of the playing source only when the playing source enters the eye protection state, so that the video is subjected to pause processing, and the playing content control module cancels the pause processing of the video stream after the detector exits the eye protection state until the barrier leaves, so that the playing is continued after the lamp source is started. Of course, the corresponding dark-tone picture can be prestored for calling in a pre-storage manner.
In the present embodiment, the detector 2 includes an infrared distance measuring sensor 21, and the distance measuring direction of the infrared distance measuring sensor 21 is consistent with the projection direction; the infrared distance measuring sensor is used for identifying the area of a projection plane and a shelter in the projection direction. The object plane in the projection direction can be marked through the infrared sensor, whether objects with different planes appear in the projection direction or not is judged through the distance between each point, and then the objects with different planes are shelters. And this area can be judged in the form of an absolute area.
In this embodiment, the test origin of the infrared sensor and the light source are located on the same plane, which can ensure the stability and accuracy of measurement and control.
In this embodiment, the detector 2 further includes a timing circuit module 22, the timing circuit module 22 is configured to obtain the retention time of the shielding object, and when the area of the shielding object exceeds the first threshold and the retention time exceeds the second threshold, the projection apparatus enters an eye protection state. By the aid of the shielding area and the retention time, it can be judged that shielding personnel do not react to mistakenly entering the preset projection range, and then the light source can cause strong light damage to the shielding personnel. On the contrary, if the sheltered person enters the projection area by mistake and quickly responds to leave the projection area, the damage to the human body is ignored, and the projection device does not need to be closed.
In this embodiment, the method further includes electrically connecting a buffer input interface 4 to the projection apparatus, where the buffer input interface is used to connect to an external storage medium to obtain a dim light tone picture pre-stored in the external storage medium; when the playing data stream of the projection device entering the eye protection state is acquired as the picture stream by the playing content control module, the playing content control module sends a frame insertion instruction, the buffer module inputs a dark light tone picture to the projection device according to the frame insertion instruction, and the projection device plays the dark light tone picture to weaken the illumination intensity of the light source. Because PPT is played as a picture stream, a technical means of inserting frames midway after pause exists, and the frames can be inserted by utilizing the stored dark light tone pictures, so that dark dimming is formed when a light source is modulated, and meanwhile, the illumination intensity of the light source is weakened, and the protection of human eyes is achieved.
In the embodiment, the detector 2 includes a depth image camera 23, the depth image camera 23 is aligned with the projection direction of the projection device 1, and the depth image camera acquires the area of the blocking object and the image feature. When the depth image camera acquires that the human eye characteristics exist in the image characteristics of the shielding object, the projection device enters an eye protection state. Because the eye protection state mainly protects the eyes of people, the eyes can be directly in the eye protection state after the characteristics of the eyes are recognized, and the priority is highest.
In this embodiment, the detector further comprises a temperature sensor, the temperature sensor is used for acquiring the temperature of the shielding object, and when the temperature of the shielding object is higher than the average value of the temperature of the human body, the projection device enters an eye protection state. So as to determine the biological characteristics of the shielding object, thereby achieving the effect of protecting the human body.
