Abstract:
Provided is a distance measuring device with a suppressed calculation amount for a parallax image. A distance measuring device 4 that generates the parallax image to measure a distance includes image sensors 3a and 3b each capturing an image, an edge image extractor 13 that extracts an edge image in accordance with the image, the edge image including pixel values each containing identification information used to identify an edge caused by a brightness variation from light to dark or an edge caused by a brightness variation from dark to light, a binarized edge image generator 15 that generates a binarized edge image in accordance with the identification information of the edge image, a parallax image generator 17 that generates the parallax image from the binarized edge image, and a distance image calculator 19 that calculates a distance image from the parallax image.

Abstract:
The present invention regards a motorised system with electric traction with computer vision for outdoor environments, which can interact with the surrounding environment in an autonomous way or remotely operated. This vehicle tows a trailer that permits, amongst other functions, to perform golf balls picking. The totally autonomous golf picking system comprises : a base (1) with, at least, two linked wheels, each driven by an independent motor; a vision system (8) with a variable amount of video cameras; a set of sensors - humidity, accelerometer, compass, coders, temperature, ultrasounds, GPS, that allow the path optimisation of the system; an image acquisition and processing system; a continuous processing unit of sensor data and motor control; a trailer with a mechanical device for picking the balls (3) and a ball container (2) with an automatic opening system (4) to an unloading dock; and a unit of rechargeable batteries through external terminals.
Abstract:
PURPOSE:To make a stop position changeable by storing the time required extending from detection of an instruction of stop to start of an operation of stop, in a presettable timer. CONSTITUTION:Usually a switch 6 is in an on-state, a motor 7 rotates, and a vehicle runs. When a mark sensor 3 detects a stop mark 2 provided on the floor surface, a presettable timer 4 starts counting. When counting proceeds to a counting value stored in the timer 4, the timer 4 turns off the switch 6. The motor 7 stops its rotation. A distance between the stop mark and a stop position of the vehicle can be changed by changing the counting value written in the timer 4. In case when this device is used for a golf cart, the stop position can be changed easily by changing the counting value written in the timer 4, therefore, a lawn is prevented from being damaged at a specified part.
Abstract:
PURPOSE: To realize an unattended conveyance system, by controlling the steering in accordance with the information which is obtained from the wheels. CONSTITUTION: Driving wheels 5R, 5L are driven by driving servomotors 9R, 9L. The driving wheels are provided with rotary encoders 7R, 7L by which right and left rotational frequencies are detected independently. From the rotational frequencies of the right and left driving wheels, which are obtained from the rotary encoders, running distances of the right and left driving wheels can be grasped, and from a difference between the running distances of the right and left driving wheels, a running direction can be known. When the information relating to the running distace and the direction is compared with a running program provided by a control operation device 12, automatic running is executed.
