Benchmark environment
The measurements are taken considering the following criteria:
- Average behaviour: measurements considering typical image processing pipelines.
Instruments:
- GPU: Jtop
- CPU: RidgeRun Profiler
- RAM: RidgeRun Profiler
- Framerate: GstShark
Engine wrapper
As mentioned previously, the Spherical Video PTZ features an engine wrapper, designed for application development. This section aims to conduct performance measurements using the average value obtained after processing the input image through the Process method of the Spherical Video PTZ engine wrapper. Below is the table displaying the results:
| n | Images type | PTZ used | Input size (px) | Output size (px) | RAM (MiB) | GPU | CPU | Avg processing time (ms) |
