Laser rangefinder (part 2)
After adding the laser, I quickly made a test program that sends the estimated range of the object via serial to the computer. The sensing algorithm on theCMUcam5 only detect the laser up to a distance of around 80cm. What’s worse? The accuracy of the sensor is mediocre at best, since the CMUucam5 only outputs an x/y coordinate in a 320x240 range, even though the OV9665 is a 1.3MP sensor. Apparently, this is due to the limited ram of the NXP processor on board, according to the guys at CMU.
