A 3.2 kHz, Stereo Sensing Module Using Two Profile Sensors

چکیده
We have developed an intelligent CMOS sensor named Profile Sensor with sampling rate at 3200Hz of X and Y projection images. The Profile Sensor is a unique CMOS sensor aimed at high-speed position sensing by detecting projection images of X and Y-axes. We have constructed a stereo sensing module by using two profile sensors and confirmed the characteristics of the module for high-speed three-dimensional position detection of multi spots using LEDs and reflectors as a target. We would like to show that the sensor has high-speed and high-accurate position measurement capabilities and can be useful for industrial and amusement applications.

متن کاملDense stereo based critical area detection for an active pedestrian protection system
An active pedestrian protection system is required to operate in realtime and produce an extremely low false alarm. To achieve these requirements, Broggi et al. detected critical areas using a laser scanner and found pedestrians only in these areas via a camera. However, using heterogeneous sensors requires complicated system architecture and laser scanners have drawbacks in terms of installabi...
متن کاملLogarithmic Image Sensor for Wide Dynamic Range Stereo Vision System
Stereo vision is the most universal way to get 3D information passively. The fast progress of digital image processing hardware makes this computation approach realizable now. It is well known that stereo vision matches 2 or more images of a scene, taken by image sensors from different points of view. Any information loss, even partially in those images, will drastically reduce the precision an...
