Table 3 Performance comparison of each sensing technique

From: Field-based high-throughput phenotyping of plant height in sorghum using different sensing technologies

Sensors Carriers Performance
Resolution Equipment cost per unit Accuracy compared with the ground truth Data processing cost
LIDAR-Lite v2 sensor Ground vehicle Low, only reflect 1-dimensional measurements < $100 Low, due to the low sampling frequency Low
Ultrasonic sensor $300–$800 High
Kinect camera ~ 0.2 MP < $300 High, within the optimal measuring range
DSLR cameras  ~ 18 MP > $800 Highest High, due to photogrammetry processing
Digital cameras UAV ~ 12 MP < $600 Lowest
