A computer vision and robotics expert has created and trained what he boasts is “the ultimate mosquito killer.” Steven Cheng shared details of his high-tech bug zapper project on social media. Key innovations here include the use of computer vision and deep learning technologies to detect and lock onto mosquitoes so the laser ‘artillery cannon’ could do its work. Spent 4 months building the ultimate mosquito killer: an artillery cannon guided by computer vision + deep learning.Trained a custom model to detect and lock onto mosquitoes using a DSLR + zoom lens setup.The dataset collection phase was brutal — the mosquitoes definitely… pic.twitter.com/jqfgz0eq9l May 28, 2026 For scanning the environment, Cheng concluded that a DSLR paired with a high-magnification zoom lens was the best option. This was also used in the training stage to build up a large dataset of mosquito images.…
