Capteur de mesure de distance - Raspberry Pi Forums

-

bonjour tous!!

je debute tout juste en programmation et aurai besoin d un peu d aide...
je recherche un capteur me permettant de mesurer une distance.
en realite je souhaite connaitre la distance qu'aura parcouru mon robot sachant qu il ne peux y avoir de lien avec la vitesse de celui-ci.
je pensais utiliser un encodeur sur lequel je viendrai grefer une roue. je pourrai ainsi connaitre, en fonction du nombre de tour effectués par la roue, la distance parcouru par mon robot. cependant je n ai absolument aucune idee du type de capteur que je devrai prendre...
auriez vous quelques conseils me proposer?
merci d avance

antoine

c'est le même principe que les souris à boule: une roue dentés et un capteur infrarouge en "fourche"

hello everyone, name kedi.. make system connecting raspberry pi 2 , arduino uno arduino adc of 1 dust sensor sharp gp2y1010au0f , 4 gas sensor. want show decision of air quality system in running text @ p10 16x32 led dot matrix display. in raspberry pi 2, connect p10 pins in gpio25, gpio12, gpio16, gpio13 & gpio26. now, i'm finish circuit , don't know must connect p10's vcc & ground (red & black wire). can me? , code in python controlling p10(1r)-v706 dot matrix?.. regards, kedi i can't python code (did mine in basic on risc os) regarding power, panels each require 2.5a, you'll need separate supply them. if attempted power them pi, pi's polyfuse blow immediately. alternatively, use supply capable of giving 10a supply both panels , pi. raspberrypi

hi, thank help. question simple: how convert raspistill data opencv processing. code: select all def capture(settings, width, height): command = "raspistill %s -w %s -h %s -t 200 -e bmp -n -o -" % (settings, width, height) imagedata = stringio.stringio() imagedata.write(subprocess.check_output(command, shell=true)) imagedata.seek(0) im = image.open(imagedata) buffer = im.load() imagedata.close() return im,buffer code: select all image1, buffer1 = capture(camerasettings, testwidth, testheight) cv2.imshow('image',image1) want use different opencv processing techniques, before need know doing wrong. bests svato raspberrypi
