CPU of airborne computer implements existing data acquisition of unpiloted vehicle with low efficiency. To improve the efficiency and to solve problems on reliability, real time and precision, the design of acquisition system based on DSP which can make a circuit acquisition for 54 channels data is put forward. After acquisition, the data can transfer between the system and CPU of airborne computer through dual-port RAM. The software and hardware methods to revise ADC on DSP are described. Evidences show that the system can meet with the flight control system on reliability, real time and precision.

In order to analyze the airborne LiDAR data corresponding to single trees and stand heights in the forestry area, we set up samples to measure tree heights of Alnus formosana, Cryptomeria japonica, and Chamaecyparis formosensis in the Alishan area. We build the Canopy Height Model based on the data from the airborne laser scanning system. Single Tree heights were estimated by averaging the CHM values within a 0.5m radius, and six different sizes of sample stands (5×5, 10×10, 12.5×12.5, 15×15, 17.5×17.5, and 20×20) were set up to extract the average heights within the area as the calculated value.
