In the elevator main body real-time monitoring mechanism: the data extraction device, the data segmentation device, the signal-to-noise ratio detection device and the background stripping device are integrated on the same integrated circuit board.
In the elevator main body real-time monitoring mechanism: and the MS storage chip is respectively connected with the signal-to-noise ratio detection device and the background stripping device and is used for storing each threshold value of each block fragment determined by the signal-to-noise ratio detection device.
In the elevator main body real-time monitoring mechanism: the image capturing device comprises a real-time display device which is connected with the uniformity detection device and used for playing the character symbols corresponding to the blurring prompt signal when the blurring prompt signal is received.
And in the elevator body real-time monitoring mechanism: the flash lamp is further used for determining the intensity of the emitted auxiliary light according to the magnitude of the current brightness value after deciding to emit the auxiliary light, and the intensity of the emitted auxiliary light is smaller when the current brightness value is larger.
In addition, in the real-time monitoring mechanism of the elevator main body, the CMOS sensor is selected to be an active pixel sensor.
CMOS sensors can be subdivided into Passive Pixel sensors (Passive Pixel Sensor CMOS) and Active Pixel sensors (Active Pixel Sensor CMOS).
A Passive Pixel Sensor (PPS), also called Passive Pixel Sensor, is composed of a reverse biased photodiode and a switching transistor. The photodiode is essentially a PN junction composed of a P-type semiconductor and an N-type semiconductor, and it can be equivalently a reverse biased diode in parallel with a MOS capacitor. When the switch tube is opened, the photosensitive diode is communicated with a vertical Column line (Column bus). A Charge integrating amplifier read circuit (Charge integrating amplifier) at the end of the column line keeps the column line voltage constant, and when the signal Charge stored in the photodiode is read, the voltage is reset to the column line voltage level, and at the same time, the Charge proportional to the optical signal is converted into a Charge output by the Charge integrating amplifier.
An Active Pixel Sensor (APS) is also called an Active Pixel Sensor. Almost at the same time as the invention of the CMOS PPS pixel structure, it was quickly realized that the performance of the pixel could be improved by introducing buffers or amplifiers within the pixel, with its own amplifier within each pixel in the CMOS APS. The amplifying transistor integrated on the surface reduces the effective surface area of the pixel element, reduces the packaging density and enables 40% -50% of incident light to be reflected. Another problem with such sensors is how to achieve a better match between the multi-channel amplifiers of the sensor, which can be better achieved by reducing the residual level of fixed pattern noise. CMOS APS has less power consumption than CCD image sensors because each amplifier within the pixel is activated only during this readout.
By adopting the real-time monitoring mechanism for the elevator main body, aiming at the technical problem that the stage elevator main body cannot be maintained by itself in the prior art, the crack detection is carried out on the top performance flat plate of the elevator main body, so that the normal performance of personnel above the top performance flat plate of the elevator main body is ensured; based on the frequency domain distribution characteristics of the image signal, performing targeted frequency division domain image processing, thereby achieving balance between the processing effect and the processing speed; determining a corresponding image segmentation strategy based on the intensity of the change of the brightness value of the pixel points in the image, and determining the size of a threshold value for background segmentation based on the signal-to-noise ratio of segmentation fragments, so that a foreground detection image prepared for background stripping can be obtained; the method comprises the steps of adjusting the light-emitting mode of a flash lamp near the image capturing device based on the detection of the ambient brightness, and determining the corresponding blurring degree based on the output content of the image capturing device so as to remind a user of corresponding adjustment when blurring is excessive, thereby solving the technical problem.
It is to be understood that while the present invention has been described in conjunction with the preferred embodiments thereof, it is not intended to limit the invention to those embodiments. It will be apparent to those skilled in the art from this disclosure that many changes and modifications can be made, or equivalents modified, in the embodiments of the invention without departing from the scope of the invention. Therefore, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention are still within the scope of the protection of the technical solution of the present invention, unless the contents of the technical solution of the present invention are departed.
