Detailed Description
The core of the invention is to provide a control method of a light source device and a related component, which can ensure the definition of an image acquired by an image acquisition device in a detection device and simultaneously avoid the damage of a user caused by overhigh temperature of a detection head of the detection device.
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the prior art, when the illumination intensity of a light source device in a detection device is controlled, the brightness value of an image acquired by an image acquisition device in the detection device is mainly used as a reference. However, for the detection devices such as endoscopes, otoscopes, dental scopes, and the like, which need to be inserted into the human body, the temperature of the detection device is also required, and the human tissue is burnt due to the excessively high temperature of the detection device, so that the illumination intensity of the light source device needs to be accurately controlled, and the requirements of the brightness of the image and the safety of the user need to be met.
Referring to fig. 1, fig. 1 is a schematic flow chart of a control method of a light source device according to the present invention, the control method of the light source device is applied to a processor of a detection device, the detection device further includes a detection head, and a light source device, an image acquisition device and a temperature acquisition device, which are all disposed on the detection head, and the control method of the light source device includes:
s1: acquiring an image acquired by an image acquisition device, and determining the brightness value of the image;
s2: acquiring a temperature value acquired by a temperature acquisition device;
s3: when the brightness value is greater than the preset brightness value and the temperature value is greater than the preset temperature value, controlling the light source device to reduce the illumination intensity;
s4: when the brightness value is smaller than the preset brightness value and the temperature value is larger than the preset temperature value, adjusting working parameters of the image acquisition device to increase the brightness value of the image acquired by the image acquisition device.
In this application except that the brightness value of the image that the image acquisition device in the detecting device gathered is as the reference basis of the illumination intensity of adjustment light source device, still fully considered the temperature value that can insert the detecting head of human body intracavity when the detecting device uses as another reference basis, control the illumination intensity of light source device through synthesizing two aspect factors of brightness value and temperature value for the image that detecting device utilized the image acquisition device to gather is clear and can not burn human tissue because of the high temperature.
Specifically, the detection head of the detection device in the application is provided with a temperature acquisition device besides a light source device and an image acquisition device, and the temperature acquisition device mainly acquires the temperature of the part of the detection head, which is also inserted into the body cavity of the human body. In order to realize the comprehensive control of the illumination intensity of the light source device, firstly, an image acquired by the image acquisition device on the detecting head needs to be acquired, and then the brightness value of the image needs to be analyzed and determined. It should be noted that, the present application is not particularly limited to the specific implementation of the light source device, the image acquisition device and the temperature acquisition device, for example, the light source device is an LED lamp, the image acquisition device is an image sensor or a micro camera, and the temperature acquisition device is a temperature sensor such as a thermistor or a thermocouple.
In practical applications, details in the picture are lost no matter the brightness value of the image is too high or too low, so that the analysis result is not accurate enough when the subsequent picture collected by the image collecting device is analyzed, and therefore, the optimal selection is to maintain the brightness value of the image at the preset brightness value all the time. Also, to ensure that the probe does not burn the body tissue, it is necessary to maintain the temperature of the probe within a reasonable range at all times, for example, when the probing device is embodied as an endoscope, it is often necessary to control the temperature of the probe to be below 42 degrees celsius.
Therefore, after the brightness value of the image collected by the image collecting device in the detecting device at the moment and the temperature value of the detecting head collected by the temperature sensor at the moment are determined in the application, if the brightness value is larger than the preset brightness value and the temperature value is larger than the preset temperature value, the light source device is controlled to reduce the illumination intensity, on one hand, the brightness value of the image collected by the image collecting device can be reduced, on the other hand, the power of the light source device can be reduced, the temperature of the detecting head can be reduced, the definition of the image can be guaranteed, and the human body can be prevented from being burnt. If the brightness value is smaller than the preset brightness value and the temperature value is larger than the preset temperature value, the brightness value of the image collected by the image collecting device is increased by adjusting the working parameters of the image collecting device, and the brightness value of the image is improved by controlling the light source device to increase the illumination intensity when the brightness value is smaller than the preset brightness value, so that the temperature of the probe is prevented from further rising, and even the danger of burning human tissues is avoided. The present application is not particularly limited to how to specifically adjust the operating parameters of the image capturing device to increase the brightness value of the image captured by the image capturing device, for example, to change the exposure time and gain of the image capturing device.
In addition, when the brightness value of the image is equal to the preset brightness value but the temperature value acquired by the temperature acquisition device on the detection head is greater than the preset temperature value, the detection head can be gradually cooled by reducing the illumination intensity of the light source device, and meanwhile, in order to ensure the definition of the image acquired by the image acquisition device, the working parameters of the image acquisition device can be synchronously adjusted, for example, the brightness of the image acquired by the image acquisition device is increased by adjusting the aperture, the exposure time, the gain and the like of the image acquisition device. When the brightness value of the image is equal to the preset brightness value and the temperature value acquired by the temperature acquisition device is less than or equal to the preset temperature value, the illumination intensity of the light source device and the working parameters of the image acquisition device do not need to be adjusted.
In summary, the present invention provides a method for controlling a light source device, which includes controlling an illumination intensity of the light source device by integrating a brightness of an image acquired by an image acquisition device and a temperature value of a detection head, and controlling the light source device to reduce the illumination intensity when the brightness value of the image is greater than a preset brightness value and the temperature value is greater than a preset temperature value, so as to prevent a user from being burned; when the brightness value is smaller than the preset brightness value and the temperature value is larger than the preset temperature value, the aim of increasing the brightness value of the image is achieved by adjusting the working parameters of the image acquisition device, the problem that the temperature of the detection head continues to rise due to the fact that the illumination intensity of the light source device is increased, and then a user is burnt is avoided, meanwhile, the noise of the image is reduced, and the usability of the image acquired by the image acquisition device is guaranteed.
On the basis of the above-described embodiment:
as a preferred embodiment, the method further comprises the following steps:
when the brightness value is larger than the preset brightness value and the temperature value is not larger than the preset temperature value, the working parameters of the image acquisition device are adjusted to reduce the brightness value of the image acquired by the image acquisition device and/or control the light source device to reduce the illumination intensity.
Referring to fig. 2, fig. 2 is another schematic flow chart of a control method of a light source device according to the present invention. In this embodiment, when the brightness value of the image collected by the image collecting device is greater than the preset brightness value but the temperature value is not greater than the preset temperature value, because the current temperature of the probe does not cause a risk of burning to human tissues, the brightness value of the image collected by the image collecting device can be reduced by adjusting the working parameters of the image collecting device, and the brightness value of the image collected by the image collecting device can be reduced by controlling the light source device to reduce the illumination intensity, or the brightness value of the image collecting device can be rapidly reduced to the preset brightness value by combining the two.
In summary, in this embodiment, when the brightness value of the image collected by the image collecting device is greater than the preset brightness value, since the temperature value of the probe is not greater than the preset temperature value, the brightness value of the image can be reduced by changing the working parameters of the image collecting device and directly reducing the illumination intensity of the light source device in any one or a combination of two ways, so as to ensure the definition of the image collected by the image collecting device and the performance of the detecting device.
As a preferred embodiment, the method further comprises the following steps:
when the brightness value is smaller than the preset brightness value and the temperature value is not larger than the preset temperature value, adjusting working parameters of the image acquisition device to increase the brightness value of the image acquired by the image acquisition device and/or controlling the light source device to increase illumination brightness.
Referring to fig. 2, fig. 2 is another schematic flow chart of a control method of a light source device according to the present invention. In this embodiment, the brightness of the image collected by the image collecting device is less than the preset brightness value, but the temperature value of the detecting head is not more than the preset temperature value, so the temperature of the detecting head can not burn human tissues, therefore, the brightness of the image collected by the image collecting device can be directly improved by controlling the light source device to increase the illumination intensity, the working parameters of the image collecting device can be changed, so that the brightness of the image collected by the image collecting device is increased, or the brightness value of the image collected by the image collecting device is rapidly increased by combining the two images, thereby ensuring the definition of the image collected by the image collecting device and ensuring the performance of the detecting device.
As a preferred embodiment, after controlling the light source device to reduce the illumination intensity, the method further includes:
adjusting working parameters of the image acquisition device to reduce the brightness value of the image acquired by the image acquisition device;
acquiring a current image acquired by an image acquisition device, and determining the current brightness of the current image;
and when the current brightness is equal to the preset brightness value, stopping reducing the illumination intensity of the light source device and stopping adjusting the working parameters of the image acquisition device.
When the brightness value of the image collected by the image collecting device is greater than the preset brightness value and the temperature value is greater than the preset temperature value, in order to avoid the user from being burnt due to the overhigh temperature of the detecting head, the brightness value of the image collected by the image collecting device needs to be reduced in a mode of controlling the light source device to reduce the illumination intensity. In this embodiment, on the basis of ensuring that the user is not burned by the probe, in order to further accelerate the purpose of reducing the image collected by the image collection device to the preset brightness value, the working parameters of the image collection device are also adjusted to reduce the brightness value of the image collected by the image collection device, and the current brightness of the current image currently collected by the image collection device is obtained in the adjustment process (the current brightness is obtained in real time or according to the preset period, which is not particularly limited in this application), and when the current brightness is equal to the preset brightness value, the adjustment of the light source device and the image collection device is stopped, so that the detection device works in the optimal state.
As a preferred embodiment, adjusting an operating parameter of the image capturing device to increase a brightness value of an image captured by the image capturing device includes:
the exposure time of the image acquisition device is increased and/or the gain of the image acquisition device is decreased to increase the brightness value of the image acquired by the image acquisition device.
Considering that the factors influencing the imaging brightness of the image acquisition device mainly include the exposure time and the gain of the image acquisition device, the brightness of the image is increased when the exposure time or the shutter speed of the image acquisition device is increased, the adjustment of the gain of the image acquisition device mainly influences the noise of the image acquired by the image acquisition device, and the noise signal in the image is amplified when the gain is increased. Therefore, when the brightness value is smaller than the preset brightness value and the temperature value is larger than the preset temperature value in the application, the process of increasing the brightness value of the image by adjusting the working parameters of the image acquisition device is specifically to increase the brightness value of the image acquired by the image acquisition device by increasing the exposure time of the image acquisition device and reduce the influence of noise generated by the image acquisition device due to darker surroundings by reducing the gain of the image acquisition device, thereby ensuring the usability of the image acquired by the image acquisition device and further ensuring the performance of the detection device.
As a preferred embodiment, after determining the brightness value of the image and acquiring the temperature value acquired by the temperature acquisition device, the method further includes:
determining an absolute value of a brightness difference value between the brightness value and a preset brightness value and an absolute value of a temperature difference value between the temperature value and a preset temperature value;
taking the product of the absolute value of the measurement difference and the absolute value of the temperature difference as an illumination adjustment coefficient;
determining a target rate for controlling the light source device to change the illumination intensity according to the illumination adjustment coefficient, wherein the illumination adjustment coefficient is positively correlated with the target rate;
when the luminance value is greater than preset luminance value and the temperature value is greater than preset temperature value, control light source device and reduce illumination intensity, include:
and when the brightness value is greater than the preset brightness value and the temperature value is greater than the preset temperature value, controlling the light source device to reduce the illumination intensity at a target speed.
In consideration of the fact that in practical application, the difference value between the brightness value of the image acquired by the image acquisition device and the preset brightness value is different, the difference value between the temperature value of the probe acquired by the temperature acquisition device and the preset temperature value is different, and when the two difference values are different, the urgency for adjusting the brightness value of the image and the temperature value of the probe is different. Therefore, in this embodiment, first, the absolute value of the brightness difference between the brightness value and the preset brightness value and the absolute value of the temperature difference between the temperature value and the preset temperature value are determined, and then, the product of the two absolute values is used as an illumination adjustment coefficient, where the larger the illumination adjustment coefficient is, the larger the difference between the brightness value and the preset brightness value and between the temperature value and the preset temperature value is, the larger the illumination adjustment coefficient is, the larger the difference is, the brightness value and the temperature value of the probe need to be quickly restored to normal values, so that the faster the target rate for changing the illumination intensity of the light source device is, that is, the greater the illumination adjustment coefficient is positively correlated with the target rate in this embodiment. When the brightness value is larger than the preset brightness value and the temperature value is larger than the preset temperature value, the light source device is controlled to reduce the illumination intensity at a target rate, the target rate is in positive correlation with the illumination adjustment coefficient, and the rate of reducing the illumination intensity of the light source device is faster when the illumination adjustment coefficient is larger, so that the detection device is quickly restored to the optimal working state.
