The ProcImage250 high speed camera is extremely easy to use. Long time period recording is available using a standard PC, and no specific acquisition card is needed. Provided that the PC has enough memory available, several hours of recording can be achieved.
The ProcImage250 has a number of smart characteristics and it offers the possibility of using smart triggers to optimise movie capture and embedded processing, enabling the user to transfer only the useful data in real time. This camera can also work autonomously, provided it is connected to a power source.
- 252 fps @ 640 x 480 (full resolution)
- USB2.0 interface
- Motherboard including a Spartan 3 FPGA
- Fast SRAM
- Real time recording on hard drive (compression without loss)
Direct recording to PC for up to several hours, in a number of different modes, as follows:
- Standard high speed camera mode: Images are taken in real time and saved on the PC, without any processing. Recording duration is limited by the hard disc memory;
- Smart high speed camera mode: The ProcImage250 integrates an FPGA and an SRAM, allowing embedded image processing that will run in real time between two images, without slowing down the frame rate. This can be as simple as thresholding, binarization, Roberts/Sobel filter, or more complex operations such as profilometry, comparison of frames, compression, etc. This allows the implementation of smart triggers to take a sequence, and/or the implementation of embedded image processing in order to transmit only useful data in real time.
Standard and smart triggers:
As standard, it is possible to trigger a sequence in 5 different ways:
- from software;
- from a TTL signal;
- from opening or closing manual remote switch;
- from a data packet sent by the network;
- from another ProcImage250.
Options: Trigger a sequence using three different approaches:
- from a sound detected by the computer’s microphone;
- from the crossing of a given grey level by a percentage of pixels in a specific area;
- from exceeding a variation of the average gray level in a specific area;
Other smart triggers are available on request.
The USB 2.0 interface used for the ProcImage250 has a number of advantages, including:
- Simplicity: USB is plug’n play
- Portability: laptop use is possible
- Multiplicity: multiple cameras can be simultaneously connected to a PC, the limit depending on the number of PC USB host controllers and the amount of data to be transmitted
Hardware Development Kit:
An HDK is available, allowing bespoke image processing (Intellectual Property) as simple as binarization and profilometry, or more complex operations such as centroid, target tracking, compression and object recognition.
