Value, laser range sensor A and laser range sensor C are finite value in the distance value that the T1 moment exports, and laser ranging passes
Sensor B and laser range sensor D is infinity in the distance value that the T0 moment exports, then can be by laser range sensor A
It is determined as two target laser distance measuring sensors with laser range sensor B, or by laser range sensor A and laser ranging
Sensor D, laser range sensor C and laser range sensor B, laser range sensor C and laser range sensor D, really
It is set to two target laser distance measuring sensors.
