We now have 2 permanently positioned CoralCams pointed at a single mature colony of Pocillopora Damicornis, a regular brooding spawner at the Horniman Museum. We’re using these cameras to determine when the corals spawn and how often. The aquarium trials will allow us to refine distance, depth of field, exposure, contrast and lighting required to build the on the computer vision classifiers we have been working on for the detection and counting of planula release. When this work is complete we’ll move this technology towards our broadcast spawning project.
Of course the project wouldn’t be complete without a couple of Raspberry Pi’s which record the footage and control the infrared LEDs using pwm via the gpio.
