In-vehicle camera device and temperature estimation method for component camera component

摘要

Problem to be solved: to obtain an in vehicle camera apparatus capable of estimating the temperature even in a part mounted at a position away from the temperature sensor.Solution: the image picked up by the lens 2 of the on-board camera apparatus 1 and the image pickup device 3 is processed.A temperature sensor 6 is installed to measure the temperature in the vicinity of the image processing unit 4 for object recognition.The temperature of the lens 2 which is a protective object installed at a position away from the temperature sensorWhen estimated by the lens temperature estimation sectionAn index indicating an insolation state around a vehicle on which the on-board camera apparatus 1 is mounted is separately obtained.Temperature measurement value of temperature sensorBased on the index indicating the solar radiation around the vehicleEstimate the temperature of lensDepending on the estimated temperatureCamera unit control unit 5The power supply of the image processing unit 4 is controlled.Diagram
