System, method and apparatus for detecting article store or retrieve operations

A method for detecting article store or retrieve operations, applicable to an article storage-retrieval cabinet and comprising:

• acquiring, by an image acquiring unit, a current image of an entrance-exit of the article storage-retrieval cabinet;
• detecting, by the image acquiring unit, marker information in the current image, wherein an edge of the entrance-exit of the article storage-retrieval cabinet is provided with a plurality of markers arranged continuously for a circle;
• and
• detecting, by a storage or retrieval detecting unit, an article store or retrieve operation based on a detection result,
• wherein in response to determining that the article store or retrieve operation has been performed, the method further comprises:
• determining, by the storage or retrieval detecting unit, an area where a marker among the plurality of markers arranged continuously for a circle is blocked, and outputting, by the storage or retrieval detecting unit, a store or retrieve signal based on a change in the area where the marker is blocked, the store or retrieve signal being configured to indicate a state of the article store or retrieve operation,
• wherein the store or retrieve signal includes an entry signal and an exit signal, the entry signal is triggered in response to a number of blocked areas being increased, and the entry signal is configured to indicate an article to enter the article storage-retrieval cabinet,
• wherein the exit signal is triggered in response to the number of blocked areas being decreased, and the exit signal is configured to indicate the article to exit the article storage-retrieval cabinet,
• wherein the store or retrieve signal further includes a start state signal and an end state signal of a store and retrieve process, wherein the start state signal is triggered in response to the number of the blocked areas changing from 0 to 1, and the start state signal is configured to indicate a start of entering the article storage-retrieval cabinet;
• the end state signal is triggered in response to the number of the blocked areas changing from 1 to 0, and the end state signal is configured to indicate to completely exit the article storage-retrieval cabinet, and
• wherein the image acquiring unit is provided at an upper right corner of the entrance-exit,
• wherein the plurality of markers form a feature array, and an interval between every two markers is less than a width of a smallest article of articles retrieved from or stored into the article storage and retrieval cabinet.

A computer device, comprising:

• a processor and a memory;
• wherein
• the memory is configured to store at least one instruction executable by the processor;
• and
• the processor, when loading and executing the at least one instruction, is caused to perform a method for detecting article storage and retrieval, applicable to an article storage-retrieval cabinet and comprising:
• acquiring a current image of an entrance-exit of the article storage-retrieval cabinet;
• detecting marker information in the current image, wherein an edge of the entrance-exit of the article storage-retrieval cabinet is provided with a plurality of markers arranged continuously for a circle;
• and
• detecting an article store or retrieve operation based on a detection result,
• wherein in response to determining that the article store or retrieve operation has been performed, the method further comprises:
• determining an area where a marker among the plurality of markers arranged continuously for a circle is blocked, and outputting a store or retrieve signal based on a change in the area where the marker is blocked, the store or retrieve signal being configured to indicate a state of the article store or retrieve operation,
• wherein the store or retrieve signal includes an entry signal and an exit signal, the entry signal is triggered in response to a number of blocked areas being increased, and the entry signal is configured to indicate an article to enter the article storage-retrieval cabinet,
• wherein the exit signal is triggered in response to the number of blocked areas being decreased, and the exit signal is configured to indicate the article to exit the article storage-retrieval cabinet,
• wherein the store or retrieve signal further includes a start state signal and an end state signal of a store and retrieve process, wherein the start state signal is triggered in response to the number of the blocked areas changing from 0 to 1, and the start state signal is configured to indicate a start of entering the article storage-retrieval cabinet;
• the end state signal is triggered in response to the number of the blocked areas changing from 1 to 0, and the end state signal is configured to indicate to completely exit the article storage-retrieval cabinet, and
• wherein the current image of an entrance-exit of the article storage-retrieval cabinet is acquired by an image acquiring unit provided at an upper right corner of the entrance-exit,
• wherein the plurality of markers form a feature array, and an interval between every two markers is less than a width of a smallest article of articles retrieved from or stored into the article storage and retrieval cabinet.
