The Ground Truth image displays a single, solid horizontal line. According to Rule 2 (UNDERSCORE & LINE RULES), if the GT contains lines used for stylistic emphasis or as background elements (like ruled paper), the OCR result must ignore them. The line in the GT is clearly a stylistic/background line, not a placeholder for text. Therefore, the OCR should not have output any underscores. Outputting `____` constitutes an error under Rule 2, as it hallucinates placeholder symbols where none are semantically intended. Hence, the OCR result is inconsistent with the Ground Truth.
Mounting in the Vehicle
Use the supplied car mounting brackets to install units on the back of the vehicle's headrests 1. Remove the 4 screws (M3x25mm) on the headrest bracket. Fix the headrest bracket into the steel pipes (dia.14mm) of the vehicle's headrest using these screws.
