This invention discloses a contamination judgment method, a contamination judgment system, and a cleaning method for a vehicle-mounted camera. The contamination judgment method includes the following steps: allowing a vehicle-mounted camera to capture a poster containing scene information through contaminated specimens of different gray levels to obtain a series of specimen images; converting the original image data of the series of specimen images into HSV format image data; extracting the mean and variance of the HSV color space of the HSV format image data of the series of specimen images as features and inputting them into a support vector machine algorithm model to train a classification algorithm model; inputting the image data of a detection image captured by the vehicle-mounted camera as input features into the classification algorithm model to allow the classification algorithm model to classify the detection image captured by the vehicle-mounted camera; and determining whether the lens surface of the vehicle-mounted camera is contaminated based on the classification result of the classification algorithm model.

The invention belongs to the technical field of vehicle test dummies, and particularly relates to a vehicle test dummy which comprises a chest, a neck is mounted at the top end of the chest, a head is mounted at the top end of the neck, a first groove is formed in the rear of the head, and a pressure sensor is mounted in the first groove. A detection plate is arranged at the pressed end of the pressure sensor; according to the vehicle test dummy, the detection plate is arranged, when a collision test is carried out, the hairpin is clamped and fixed through the two guide plates, when the collision test is carried out, torque generated by extrusion between the hairpin and the back of a seat is transmitted to the pressure sensor through the detection plate, and the pressure sensor transmits data to an external computer; a worker analyzes how much hurt can be generated to a driver by the hairpin according to the data; and the real condition of wearing the hairpin is simulated.
