The HVC-P2 sensing unit that I am road testing is using the Omron OKAO Vision technology. Omron has developed a number of models of these "Human Vision Components" (HVC) but I've found it difficult to find documentation on them. In 2005 Omron introduced the OKAO Vision Face Recognition Sensor that was apparently intended to be integrated into mobile phones for owner facial recognition. According to their White Paper released in May 2018 Omron has been licensing the OKAO technol ...
I'm still working on the procedure that I want to use to test the performance of the HVC-P2. While I was pondering, I thought I'd try hooking the unit up to a Linux laptop. Of course that was a disaster. I stepped into the 32bit/64bit hole again. The laptop I'm using is running the 64bit version of the Ubuntu 16.04 OS. I configured all the software but immediately upon executing the python script I got the evil ELFCLASS32 error. The libSTB.so library of stabil ...
Road Test Introduction It was an honor to be selected for the road test of the Advantech USB-5830 16 channel digital I/O (each) module. I have been working with crypto-mining rigs and had felt that there is a need to architecting a “smart” high-density facility power management system. It was fortuitous that the USB 5830 actually appears to be an easy path to integrate a potentially very high-density AC power switching system. Since each module could support 16 dig ...
Since I have the HVC-P2 working with the Evaluation Software GUI on my Windows 10 box, it seemed logical to try out the sample python code there before moving to the Raspberry Pi. This code was written at least a couple of years ago so it has dependencies on old software. Software Requirements: 1) Python 2.7 2) pySerial library 3) Python Imaging Library (PIL) I normally don't use python2, so I needed to install that. And PIL is no longer supported, so I installed ...
I had some time this weekend to 3D print a case for the HVC-P2 assembly. I just wanted something simple to protect the boards and to provide the capability to mount the unit on a tripod so that I would have a stable adjustable base for my testing. I also wanted something that will allow me to add a Raspberry Pi Zero Wireless later. I opted to to not do a "compact" design although I may want to do a redesign later. I also spent some time reading through the ...
I received my Omron Vision Sensor yesterday via UPS. The box was so light that is seemed empty; but there was the kit wrapped in bubble wrap in a static bag. The kit consists of a Camera board (25mm x 25mm) that is the size of an RPi camera and an image processor board (45mm x 45mm) connected with a 9cm flex cable.. I am going to have to print an enclosure to support and protect the boards so that I don't damage them in use. The communication and power to the processor board ...
I was fortunate to be selected as the roadtester for the Omron HVC-P2. I just received notification that the unit should arrive next week, so I thought I should do some research to prepare for the roadtest. It appears that this is Omron's second iteration of the HVC hardware. The HVC-P1 has a lower resolution camera (640x480) that is integrated on the recognition processing board. The HVC-P2 has a much higher resolution camera (1600x1200) and the camera is on a separate ...
I have a long held secret that I have never revealed to anyone. But I'm ready to announce it now. (Let the drums roll!) Here it is: I have always wanted to be an astronaut. Phew! I finally got that off my chest. Take a deep breath, Randall. (Now I can relax.) I grew up in rural Wisconsin during the days of the Mercury and Gemini space programs. As a boy, I was inspired by these early astronauts and I felt space was the greatest adventure of a lifetime. Growing up with the ...
