The invention provides a container as well as a lighting control method thereof, and a computer readable storage medium. The container comprises a cabinet body, a door body, a camera device, a first lighting module, a second lighting module and a controller, wherein the door body is arranged at an opening of the cabinet body in a retractable way; the camera device is arranged on the cabinet body;the first lighting module is arranged on the cabinet body and is used for providing light for the interior of the cabinet body; the second lighting module is arranged on the cabinet body and is used for providing light for the camera device; the controller is connected with the first lighting module and the second lighting module; the controller is used for controlling the working states of the first lighting module and the second lighting module according to the opening and closing states of the door body. According to the container provided by the invention, the working states of the first lighting module and the second lighting module are controlled by means of the controller according to the opening and closing states of the door body, so that the service lives of the first lighting module and the second lighting module are effectively prolonged under the premise that the information such as the commodities and the price tags is displayed in a highlighted way so as to stimulate consumption.

The invention discloses a multifunctional intelligent blind guiding method. The multifunctional intelligent blind guiding method comprises the following steps of receiving a voice command, and navigating; obtaining image data of an obstacle; carrying out recognition processing on digital image data, judging that threat is formed by the obstacle if the recognized obstacle is a static body, generating an ultrasonic ranging control command, and generating and outputting voice alarm information or vibration prompt information according to a ranging result if the ranging result is within a preset alarm range; and generating an ultrasonic ranging control command if the recognized obstacle is a dynamic body, carrying out threat anticipation calculation according to a ranging result, and generating and outputting voice alarm information or vibration prompt information if the obstacle is within a preset alarm range. The invention also discloses a multifunctional intelligent blind guiding device and a processor. According to the multifunctional intelligent blind guiding method, the multifunctional intelligent blind guiding device and the processor, which are disclosed by the invention, the blind guiding service can be more safely, conveniently and reliably provided for the blind, the blind is prevented from walking more distance and meeting the obstacle, and thus the blind can quickly and safely arrive at the destination.

An image processing method generally includes: obtaining a vanishing point on a curve surface in a two-dimension image; extracting all the straight line segments between a top contour line and a bottom contour line of the curve surface by the vanishing point; removing a perspective distortion to get parallel straight line segments; obtaining the lengths of the straight line segments, obtaining the true width of each of the straight line segments in a three-dimension space and the depth increment of the straight line segments according to the lengths; obtaining the expanded width of each straight line segment according to the true width and the depth increment; obtaining the total expanded width of the curve surface to transform it into a flat surface; transforming image contents on the curve surface onto the flat surface. The method can be applied when scanning an open book.
