Threshold adjustment method, processing device, and electronic device

A threshold adjustment method executed by a processor of a radar scanning module when a radar scanner of the radar scanning module operates in a second mode, wherein the processor controls the radar scanner to switch between a first mode and the second mode, the radar scanner being configured to scan a preset range to generate a plurality of radar echo data entries, and wherein the processor pre-stores a preset threshold table in a storage unit, the preset threshold table storing a plurality of preset thresholds respectively corresponding to different coordinates within the preset range, the threshold adjustment method comprising:

• generating a scanning result based on the plurality of radar echo data entries and at least one of the plurality of preset thresholds, and determining whether the scanning result corresponds to a switching condition;
• in response to determining that the scanning result corresponds to the switching condition, determining whether the scanning result corresponds to a preset ignore state;
• in response to determining that the scanning result corresponds to the preset ignore state, modifying at least one threshold in the preset threshold table;
• and
• switching the radar scanner to the first mode.
