360° panoramic camera solution to be developed

The solution utilises the Rockchip RV1108 visual processor which leverages the CEVA-XM4 imaging and vision DSP to run advanced imaging and computer vision algorithms, including real time distortion correction and panoramic stitching. The solution has already been adopted by ODMs and products are available in the market.

PiSoft developed their solution to address the growing demand for 360° cameras, which are being rapidly adopted, in part to generate more virtual reality content. Utilising their capabilities as a complete technology solution provider, PiSoft built a system on the RV1108 processor, that allows them fully exploit their vision algorithm expertise via the CEVA-XM4 engine and generate outstanding 360° image and video quality. Compared to implementing their algorithms on the CPU within the system, the CEVA-XM4 was 36 times more efficient for distortion correction and 60 times more efficient for stitching. These considerable performance advantages together with the low power performance, allowed PiSoft to fully exploit the capabilities of their software, and create a product, which offers a differentiated experience from competing solutions, while consuming significantly less power.

“To bring our advanced vision expertise to the market, we chose the RV1108 chip with the CEVA-XM4 DSP due to the outstanding performance we could achieve for running our complex vision algorithms,” said Adler Shen, CEO of PiSoft. “CEVA’s powerful suite of development tools ensured we easily and efficiently developed our vision algorithms and allowed us to meet our development goals and reach production ODM customers in record time.”

“We applaud PiSoft’s ability to develop a full solution for panoramic cameras, from system design to software implementation, that offers exceptional 360° video and image quality,” said Ilan Yona, Vice President and General Manager of the Vision Business Unit at CEVA. “Our CEVA-XM4 DSP and software development environment, plays an essential role in the success of this product, enabling PiSoft achieve a huge performance advantage over alternative systems that rely on the CPU or GPU to run vision algorithms.”

RV1108 is a high performance low power application processor. It is embedded with a CEVA-XM4 DSP for imaging and computer vision algorithms and an ARM Cortex-A7 single core processor for system and application. It is a highly integrated and cost efficient SoC, which can support H.264 video encoder/decoder up to 1440p, up to four camera inputs simultaneously, merge different camera sources together and display on one screen. It is designed for various application scenarios such as car DVR, sports DV, secure camera and UAV camera.
