Sounds like a good DVS application. I have measured closed loop latency via USB in and USB out (with USB1.0 full speed output to servo controller) with about 2-3ms median latency on windows.Tobi Delbruckhttps://www.blogger.com/profile/11104032358783859871noreply@blogger.comtag:blogger.com,1999:blog-19092890.post-4115755280259335072018-03-12T08:58:55.178+02:002018-03-12T08:58:55.178+02:00right, there is an email-form.

An optical mouse uses an tiny image for motion calculation, the frame rate can be easily more than 5Khz.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-80802292003858370222018-03-09T10:42:09.990+02:002018-03-09T10:42:09.990+02:00But you'll detect only the contour of the shad...But you'll detect only the contour of the shade, which is not that much more data.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-9291162655402383742018-03-09T08:17:47.380+02:002018-03-09T08:17:47.380+02:00Does Chronocam/Prophesee really offer a product or...Does Chronocam/Prophesee really offer a product or are they still in powerpoint mode only? I tried to contact them several times without success via email about a potential applicaton in robotics asking for rough product specs. I am also suprised that they dont have a phone number on their website and apart from generic slides no product details.<br />Are event based image sensors available? I find some on https://inivation.com but are there alternatives? <br />The task I am interested in is to close a servo axis control loop over the camera image. So to "replace" (or cascade) a servo axis encoder by positoin information from a camera image. To control the position of a robot axis (where the camera is mounted) relative to the position of a fiducial tracked by the camera. <br />The problem with conventional cameras is the bandwidth. Even with a strong PC you hardly reach the 1kHz range. DVS seems to be an alternative with high potential...<br />What about QIS? Would the QIS approach open the door for tracking objects with high temporal resolution?<br />Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-87936718203674723242018-03-09T04:20:49.571+02:002018-03-09T04:20:49.571+02:00Here's a thought, see those shadows moving wit...Here's a thought, see those shadows moving with the vehicles?
