This week I worked on two things. First, I worked on getting our camera, the Intel Realsense setup. We were able to obtain a new camera with its cable, and get it somewhat working on one of our team member’s laptop, and it also worked well on our TA (Tao’s) laptop. The next step is to connect the camera with the Jetson Xavier and get it setup there.
I also worked on the laser detection algorithm. I tried a few different methods that I found online with varying results. The first algorithm that I tried only used the RGB values of the image, and manipulated these values to calculate the degree of red compared with the other pixel values. The results are shown below, where the laser is the circular spot:
The next algorithm I used involved using the HSV values and thresholding then, and then anding these values to find the laser in the image. This method seemed to work, but need more testing to determine the best threshold values. The results are shown below, with the laser in pink:
Overall both algorithms were able to detect the laser in a simple example, but I will need to perform more testing to determine which algorithm is preferred when shining the laser on an object. Next week, I plan to work on setting up the camera and improving on this algorithm.
