Could Not Create Dir at /home/pi/tmp_cv3

[twenty4k]

New to PI/coding and your tutorial seem to be the best written and most comprehensive for beginners.

However, I am running into this issue:

Could Not Create Dir at /home/pi/tmp_cv3 │ │ Check permissions │ │ If on a mounted Device make sure │ │ 1- Device is mounted and is NOT FAT32 │ │ 2- Device Must be writeable by Pi user. │ │ Check ownership and permissions │ │ │ │ Exit to Terminal to Investigate

Here is the code

./cv3-install-menu.sh: line 122: $LOG_FILE: ambiguous redirect STEP 2 Install opencv 4.1.2 Build Dependencies

This step will install opencv 4.1.2 Build Dependencies Then Download and unzip opencv source files to /home/pi/tmp_cv3 Folder

---------------- STEP 2 INSTRUCTIONS --------------- A Fresh Build Needs at Least 16GB SD with 5-6 GB Free. Free Space could be less depending on what dependencies are already installed If you are using a smaller system SD or are Low on Free Disk Space. You can mount USB media and change variable INSTALL_DIR in this script. Installs Will Take a While so be Patient ...

Install Dep and Source? (y/n)? y

Thanks for responding so quickly. I think there was an issue with the OS I was using. I reflashed my RPI and reinstalled your program. Works great! I'm a tinkerer and new to RPI and programming. Appreciate your thorough walkthrough.

I am having an issue with the program not capturing images of vehicles moving faster than 25mph. I'm using RPI 4 and Camera Module 3 Standard Lens. Would the wide angle lens be better for this application? My setup is probably 50ft from the road.

Thanks!
