no. 1 Embodiment approach ＞
[0016] refer to Figure 1 to Figure 3 A first embodiment related to the on-vehicle detection device will be described. exist figure 1 Among them, the vehicle-mounted detection device 100 is mounted on the vehicle 1 . The vehicle-mounted detection device 100 is configured to include a camera 11 , a sensor 12 , a processing unit 13 , a GPS (Global Positioning System) 14 , and a map database (DB) 15 . exist figure 1 In the diagram, a dotted line represents an example of an imaging range of the camera 11 , and a dotted line represents an example of a measurement range of the sensor 12 .
[0017] The sensor 12 is a different type of sensor from the camera 11 . For the sensor 12, for example, millimeter-wave radar, laser radar (Light Detection and Ranging), far infrared (Far Infrared Rays: FIR) sensor, ultrasonic sensor (also called "sonar"), TOF (Time-of-Flight : time-of-flight) sensors, etc. That is, the sensor 12 is a different type of sensor from the camera 11 that can be ...
no. 2 Embodiment approach ＞
[0041] refer to Figure 4 and Figure 5 A second embodiment related to the on-vehicle detection device will be described. The second embodiment is the same as the above-mentioned first embodiment except that the operation of the processing unit 13 is partially different. Therefore, for the second embodiment, descriptions that overlap with those of the first embodiment are omitted, and the same reference numerals are assigned to the same parts in the drawings, and for basically different parts, refer to Figure 4 and Figure 5 Be explained.
[0042] In the above-mentioned first embodiment, in the area where the detection is completed (refer to Figure 4 In the “area r1 ” and “area r2 ” of ), there may be information that affects the traffic of the vehicle 1 , such as traffic lights, road signs, and signboards. For example, the light color of a traffic signal, the content of a road sign, etc. cannot be recognized from the measurement result of the sensor 12 .

Abstract
An in-vehicle detection device and a detection method are disclosed. The in-vehicle detection device is mounted on a vehicle. The in-vehicle detection device includes a camera configured to capture a first range around the vehicle as a capturing range; a sensor different in type from the camera and configured to set a second range as a measurement range with the second range overlapping with at least a part of the first range; and a processor configured to perform detection processing on an image captured by the camera. The processor is configured to identify a first area that is included in the image and is excluded from the target of the detection processing based on the measurement result of the sensor and is configured to perform the detection processing on a second area that is included in the image and is not included in the first area.
Description
technical field [0001] The invention relates to the technical field of a vehicle-mounted detection device and a detection method. Background technique [0002] As such a device, for example, an image processing device has been proposed that determines whether there is a parked vehicle within a parking frame based on an image captured by a single-lens reflex camera mounted on a vehicle (see JP 2020-095629 ). [0003] Like the technique described in JP 2020-095629, image processing is performed on an image captured by an on-vehicle camera to detect obstacles and the like existing around the vehicle. On this basis, for example, in order to achieve safe and secure driving of vehicles based on autonomous driving technology, multiple cameras are mounted on vehicles, or high-resolution cameras are used as on-board cameras, or the frequency of shooting by on-board cameras is increased. Therefore, the amount of computation required for image processing increases. As a result, a hig...
