Object searching method, object searching device and object searching system

An object searching device, comprising:

• an output/input element, configured to receive a user message;
• a memory, configured to store a locator mapping table and a feature direction map;
• and
• a processor, configured to analyze an object name from the user message, and to obtain a locator corresponding to the object name according to the locator mapping table;
• and
• a detection element, configured to detect a locator distance and a locator direction of the locator;
• wherein the processor is further configured to generate a description string according to the locator distance, the locator direction, and the feature direction map, and generate a voice message according to the description string and the object name, wherein the output/input element broadcasts the voice message.

An object searching system, comprising:

• a first object searching device, located at a first space, configured to receive a user message, analyze an object name from the user message, obtain a locator corresponding to the object name according to a locator mapping table, and detect the locator, when the first object searching device is unable to detect the locator, the first object searching device transmits a searching instruction;
• and
• a second object searching device, located at a second space, communicatively connected to the first object searching device, configured to detect a locator distance and a locator direction of the locator according to the searching instruction, generate a description string according to the locator distance, the locator direction, and a feature direction map of the second object searching device, and transmit the description string to the first object searching device;
• wherein the first object searching device is further configured to generate a voice message according to the description string and the object name, and broadcast the voice message.
