Vehicle Based Laser Range Finding in Crops
Laser rangefinders and laser scanners are widely used for industrial purposes and for remote sensing. In agriculture information about crop parameters like volume, height, and density can support the optimisation of production processes. In scientific papers the measurement of these parameters by low cost laser rangefinders with one echo has been presented for short ranges. Because the cross se...
متن کاملLaser Range Finding Based on Correlation Method
The purpose of the paper is to present a new laser diode range finding method. The system belongs to the category of flight time measurement. The optical power of the laser diode beam is modulated and then both emitted and returned signals are compared in order to obtain the delay or distance information. The new method is an estimation of the distance by correlation computation. The main advan...
متن کاملA survey of Laser Range Finding
This report provides a informal survey of laser distance measurement. Applications of laser range finding are briefly discussed and various techniques for laser ranging such as active laser triangulation, pulsed time-of-flight (TOF), phase shift, FMCW, and correlation are described.
متن کاملCCD-Based Range-Finding Sensor
Integration-time-based, time-domain computation provides an area-efficient way to process image information by directly handling photo-created charge during photo-sensing. We have fabricated and tested a CCD-based range-finding sensor which uses the time-of-flight method for range measurement. The sensor exploits two charge packets for light integration and detects the delay of the received lig...
متن کاملStreet-Parking Vehicle Detection from Panoramic Laser Range-Image
It is important to assess street-parking vehicles causing traffic problems in urban areas, however, it is performed manually and at high cost. It is a top priority for reducing cost, to develop a detection system of those vehicles. We propose a detection method using a laser-range finder and a line-scan camera. In the detection method, two kinds of cluster analysis are applied to range points: ...
