Detailed Description
The present invention will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present invention more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
In one aspect, as shown in fig. 1, an embodiment of the present invention provides a method for automatically adjusting brightness of a light box, including:
s100, responding to an identification instruction of a target object in a target area, and acquiring an image of the target area to obtain a target image;
in some embodiments, the method may further include: identifying and detecting a target area through a human body infrared detection device; when the detected target object is identified in the target area, an identification instruction is triggered.
In some embodiments, in response to an identification instruction of a target object in a target area, image acquisition is performed on the target area, including: responding to an identification instruction of a target object in a target area, and starting an image acquisition device; and acquiring an image of the target area through an image acquisition device.
S200, acquiring the ambient light brightness data of a target area;
it should be noted that, in some embodiments, step S200 may include: and periodically collecting the ambient light brightness data of the target area through an ambient light detection device.
S300, analyzing and processing the age bracket of the target object according to the target image to obtain age data of the target object;
it should be noted that, in some embodiments, step S300 may include: collecting a face image of a target object from a target image; facial feature analysis is performed on the facial image, and age data of the target object is obtained based on the result of the facial feature analysis.
Illustratively, in some embodiments, age identification may be generally implemented in two stages:
stage 1: detecting a face in an input image/video;
stage 2: the face of the person (region of interest, ROI) is extracted and the age of the person is predicted by an algorithm of an age detector.
For phase 1, face detectors are available that can generate a bezel for a face in a picture, including but not limited to Haar cascades, HOG + linear SVM, single bar detectors (SSD), etc. The advantages and disadvantages of various face detectors are as follows
Haar cascades are fast and can run in real time on embedded devices, with the problem that they are less accurate and are very prone to false positive detection.
The HOG + linear SVM model is more accurate than Haar cascades, but at a slower rate. They are also less tolerant to occlusion (i.e., portions of the face are visible) or changes in viewing angle (i.e., different views of the face).
The deep learning based face detector is the most powerful, providing the highest accuracy, but requires more computational resources than Haar cascades and HOG + linear SVMs.
When the face detector is selected in practical application, the corresponding face detector can be selected based on the emphasis of different detection speeds or detection accuracy.
After the boundary box coordinates of the face are generated in the image/video based on the face detector, stage 2, which identifies the age of the person, can be entered. The specific flow is as follows:
after the bounding box coordinates (x, y) of the face are determined, the face ROI is first extracted, while the rest of the image (frame) is ignored. This may be done so that the age detector only focuses on the face, not other irrelevant "noise" points in the image.
The facial ROI is then passed to the model, resulting in an actual age prediction.
There are many algorithmic models of age detectors, and the model used in the embodiments of the present invention is not particularly limited, and for example, an age detector based on deep learning may be used as the age detection model.
S400, determining a brightness adjustment value according to the ambient light brightness data and the age data;
it should be noted that, in some embodiments, step S400 may include: determining a first adjustment value according to a first difference value between the ambient light brightness data and a preset reference brightness; determining a second adjustment value according to a second difference value between the age data and a preset reference age; and determining a brightness adjustment value according to the first adjustment value and the second adjustment value.
In some embodiments, determining the brightness adjustment value according to the first adjustment value and the second adjustment value may include: and according to the first adjustment value and the second adjustment value, carrying out weighted summation by combining preset weights to obtain a brightness adjustment value. For example, the weight of the brightness adjustment of the light brightness data of the heavy environment or the light brightness adjustment of the light age data of the heavy environment can be adjusted according to the actual application requirement, and the default weights are 1, that is, the first adjustment value and the second adjustment value are directly added to obtain the final brightness adjustment value.
S500, carrying out self-adaptive adjustment on the brightness of the lamp box according to the brightness adjustment value.
In some embodiments, the compensation is performed by overlaying the parameters of the ambient brightness with the pre-stored parameters of the appropriate brightness corresponding to the age. For example: the program sets a basic brightness of the lamp box, the age exceeds 30 years, and the brightness value of the lamp box increases by 5% every 5 years of age; the brightness of the lamp box is increased by 5% every 5% compared with the reference brightness.
For the purpose of illustrating the general principles of embodiments of the present invention in detail, the following general flows of embodiments of the invention are described in connection with the accompanying drawings and some specific embodiments, it being understood that the following is an explanation of the invention and is not to be construed as limiting the invention.
The embodiment of the invention provides a method for automatically adjusting the brightness of a lamp box of lottery auxiliary equipment, which aims to solve the problem that the brightness of the lamp box of the lottery auxiliary equipment cannot be automatically adjusted. The specific flow is as follows:
detecting a target object in the area through a human body infrared detection device on the lottery auxiliary equipment, and carrying out image acquisition on the target area through an image acquisition device on the equipment to acquire a target image; and obtaining regional ambient light brightness data (first data) through an ambient light detection device on the equipment.
Further, age group analysis is performed on the user based on the target image, so that user age data (second data) is obtained.
Further, the required target value data (third data) is determined based on the first data and the second data analysis.
And further adjusting the brightness of the lamp box according to the third data.
In order that the above-recited objects, features and advantages of the present invention will become more readily apparent, a more particular description of the invention will be rendered by reference to the appended drawings and appended detailed description.

Specifically, the system stores appropriate brightness parameters corresponding to the ages, and then superimposes parameters of the ambient brightness to comprehensively compensate. For example: the program sets a basic brightness of the lamp box, the age exceeds 30 years, and the brightness value of the lamp box increases by 5% every 5 years of age; the brightness of the lamp box is increased by 5% every 5% compared with the reference brightness.
