1. A multi-function cart control method, the method comprising:

using an adult detection device connected to the histogram equalization device for performing an adult target search on the equalization-processed image based on the standard adult profile to issue a first control command when the adult target is searched;

the adult detection device is also used for sending a second control command when the adult target is not searched;

the guardrail driving device is connected with the adult detection device and used for erecting the railings around the infant trolley to realize protection action when receiving a second control command;

the railing driving equipment is also used for putting down railings around the baby stroller to relieve the protection action when receiving the first control command;

the data capturing device is arranged on the baby stroller and used for capturing image data towards the surrounding scenes of the baby stroller so as to obtain and output a corresponding surrounding image of the baby stroller;

the using parameter adjusting device is connected with the data capturing device and used for receiving images around the trolley and performing color level adjustment on the images around the trolley to obtain and output field adjusting images;

using a custom sharpening device which is respectively connected with the parameter adjusting device and the redundancy identification device and is used for starting image sharpening processing based on Prewitt operator on the received field adjusting image when the redundancy of the received field adjusting image exceeds the limit so as to obtain a corresponding custom sharpened image;

the user-defined sharpening device is further used for starting sharpening processing on the received on-site adjustment image in the horizontal direction and then sharpening in the vertical direction when the redundancy of the received on-site adjustment image is not over the limit, so that a corresponding user-defined sharpened image is obtained;

using a histogram equalization device connected with the custom sharpening device and used for executing histogram equalization processing on the received custom sharpened image to obtain and output a corresponding equalized image;

using a channel value sequencing device, connected to the parameter adjusting device, for receiving the field adjustment image, and sequencing the gray values of the pixels in the field adjustment image to obtain the maximum sequence number of the sequencing queue;

using a redundancy identification device connected with the channel value sorting device and used for receiving the maximum sequence number and determining the redundancy of the field adjustment image inversely proportional to the maximum sequence number;

in the channel value sorting device, sorting the gray values of the pixels in the field adjustment image includes: pixel points with the same gray value occupy the serial number of the same queuing sequence;

the user-defined sharpening device is used for interrupting the image sharpening processing of the received on-site adjustment image based on the Prewitt operator when the redundancy of the received on-site adjustment image is not over the limit;

the user-defined sharpening device is used for interrupting the sharpening processing of the received on-site adjustment image in the horizontal direction and then in the vertical direction when the redundancy of the received on-site adjustment image exceeds the limit.

2. The multi-function cart control method of claim 1, wherein:

the user-defined sharpening device is one of a programmable logic device or a field programmable gate array device;

wherein the channel value sorting device is connected with the redundancy identification device through a serial communication interface.

3. The multi-function cart control method of claim 2, further comprising:

using distortion processing equipment, connected with the data capturing equipment, for receiving the images around the cart, equally dividing the images around the cart into blocks with corresponding block sizes based on the distance between the signal-to-noise ratio level of the images around the cart and a preset lower limit signal-to-noise ratio level, selecting corresponding distortion processing with different strengths for each block based on the pixel value variance of the block to obtain adjusted blocks, and combining the obtained adjusted blocks to obtain an adjusted and combined image; in the distortion processing device, the farther the signal-to-noise ratio level of the cart peripheral image is from a preset lower limit signal-to-noise ratio level, the larger the corresponding block into which the cart peripheral image is equally divided, and in the distortion processing device, the larger the variance of the pixel value of each block is, the smaller the selected distortion processing strength is.

4. The multi-function cart control method of claim 3, wherein:

the distortion processing equipment is also connected with the parameter adjusting equipment and used for replacing the images around the cart with the adjusted and combined images and sending the images to the parameter adjusting equipment.

5. The multi-function cart control method of claim 4, further comprising:

using signal-to-noise ratio improving equipment, which is connected with the distortion processing equipment and used for performing signal-to-noise ratio improving operation on the images around the trolley before the distortion processing equipment performs distortion processing on the images around the trolley and when the signal-to-noise ratio level of the images around the trolley is smaller than the preset lower-limit signal-to-noise ratio level, replacing the images around the trolley with the images around the trolley after the signal-to-noise ratio improving operation and inputting the images to the distortion processing equipment, and when the signal-to-noise ratio level of the images around the trolley is larger than or equal to the preset lower-limit signal-to-noise ratio level, not performing the signal-to-noise ratio improving operation on;

and using an SGRAM storage device, connected with the distortion processing device, and used for pre-storing the preset lower-limit signal-to-noise ratio level.
