Detection-based wakeup of detection devices

A detection system, comprising:

• a first detection device configured to generate detection results based on objects detected in a first detection region;
• a second detection device configured to generate detection results based on objects detected in a second detection region, wherein the second detection region overlaps at least a portion of the first detection region;
• and
• a mapper device configured to generate a mapping that comprises a first plurality of entries, wherein each of the first plurality of entries associates a respective detection result of the first detection device with a respective detection result of the second detection device,
• wherein the second detection device is further configured to transition to a first power mode upon completion of generation of the mapping,
• wherein the first detection device is further configured to determine that a first object of a first object type is detected based on the mapping, and
• wherein the second detection device is further configured to:
• transition out of the first power mode when the first object of the first object type is determined to be detected;
• and
• perform at least one action based on the first object.

A detection device, comprising:

• at least one processing circuit configured to:
• while a second detection device is in a lower power mode, determine that a first object of a first object type is detected based on a mapping, wherein the mapping associates detection results of the detection device with classifications generated by the second detection device;
• and
• facilitate transition of the second detection device out of the lower power mode when the first object of the first object type is determined to be detected by the detection device.
