If the distance calculated in S520 is equal to or smaller than the threshold, it is determined that the circumscribed rectangle is located in an area near the camera 13, and the extracted area is estimated to be a part of the obstacle, and the feature of the obstacle is extracted (S504). . Specifically, in S506, it is checked whether or not a circle that is a feature of the helmet exists in the extraction region. In S506, when it is determined that a circle exists, the extraction area is determined to be a worker (person) wearing a helmet (S510), and when it is determined that a circle does not exist, It is determined that the extraction area is a thing (S511).
- the distance calculated in S520 is larger than the threshold value in S503, it is estimated that the entire obstacle is photographed in the extraction area, and the feature of the obstacle is extracted (S505).
- the aspect ratio of the extraction region is close to that of a person standing, or the extraction region is divided into a head portion, a torso portion, and a lower portion, and each contour shape, color, and the like are set. It is determined whether or not there is a feature of the person's head, trunk, and lower part.
- step S501 the processes in and after S501 are repeated.
- the relative position of the obstacle detected by the obstacle detection unit 400 with respect to the hydraulic excavator can be calculated.
- a method different from the above may be applied in the subsequent type determination processing (S506, 507) according to the result determined in step 503.

Specifically, in association with the operation of the hydraulic excavator, a danger range 916 is calculated that has a wide range in the left direction that is the turning direction and a narrow range in the rear or right direction that is different from the turning direction.
- FIG. 12 is an explanatory diagram of a calculation example of the danger range when the lower traveling body 1e moves backward.
- the danger range calculation unit 700 calculates the danger range based on the operation state using the size (horizontal width) of the excavator taken in step 707. Specifically, a danger range 918 having the same width as the lateral width of the excavator is calculated on the rear side of the excavator that is the moving direction.
- FIG. 13 is a flowchart of processing performed by the determination unit 800 according to the embodiment of the present invention.
- the determination unit 800 determines whether or not there is an obstacle detected by the obstacle detection unit 400 within the danger range calculated by the danger range calculation unit 700. A determination is made based on the position of the obstacle calculated by the position calculation unit 500 (S801, 802). If it is determined in S802 that it is within the danger range, the result is stored in the storage device (S803), and if it is determined that it is outside the danger range, the result is similarly stored in the storage device (S804). ). The determination result stored in this way is used in other processing (for example, the risk setting unit 2000). When the writing to the storage device is completed, the determination in S801 is repeated for every obstacle for each time. By this processing, it can be determined whether or not each obstacle exists within the danger range.
- FIG. 14 is a flowchart of processing performed in the risk setting unit 2000 according to the embodiment of the present invention.
- the risk setting unit 2000 first checks whether an obstacle exists within the danger range based on the determination result of the determination unit 800 (S2051). . If it is determined in S2051 that there is no obstacle in the danger range, the process is terminated without setting the contact danger level (set the danger level to 0) (S2071). On the other hand, if it is determined in S2051 that an obstacle exists within the danger range, the danger range is determined based on the type, position, and height of each obstacle obtained from the image of the camera 13 in the processing in S2052 and the subsequent steps. The contact risk is set for each obstacle existing inside.
- the danger level setting unit 2000 checks whether or not the obstacle is a person with respect to an obstacle that does not have a contact danger level within the danger range. If it is determined in S2052 that the obstacle is not a person (that is, the obstacle is an obstacle), the height of the obstacle is set to a predetermined height (for example, 200 cm) (S2073), and the process proceeds to S2063.
- a predetermined height for example, 200 cm
- the circumscribed rectangle has a vertically long shape. Whether or not two adjacent sides are equal in length is determined (S2053). If it is determined in S2053 that it is vertically long or equivalent, it is estimated that a person standing in the extraction area is included, and its height is set to a set value (for example, 180 cm) (S2054). The process proceeds to S2056.
- S2056 it is determined whether the operation of the excavator is turning (right turning and left turning) or reverse based on the operation signal of the operating device or the time change of the detected angle ⁇ 4 of the angle detector 8d.
- the contact risk is set to 2 (S2057), and the process proceeds to S2070.
- the process proceeds to S2058.
- S2058 it is determined whether or not the obstacle is a person present at a position closest to the operation direction of the excavator as compared with other obstacles within the danger range. Specifically, if it is determined in S2058 that the excavator is turning, first, the radius of the circle centered on the turning center of the excavator is gradually increased from 0 to the bucket tip, thereby increasing the plurality of excavators. Draw concentric circles. Then, it is determined whether or not the obstacle whose target contact risk is to be set is a person who is present at a position closest to the front work apparatus 1A in the turning direction on the plurality of concentric circles.
- step S2058 it is determined whether or not the obstacle for which the contact risk level is set is the person closest to the rear side of the excavator. judge. If it is determined in S2058 that the obstacle is the person closest to the direction of operation of the excavator, the contact risk is set to 5 (S2059), and the process proceeds to S2070. That is, in S2059, among obstacles whose type is within the danger range, the obstacle is present at the position closest to the front work device 1A or the hydraulic excavator in the turning direction of the front work device 1A or the backward direction of the hydraulic excavator. The highest contact risk is set for the person (obstacle). On the other hand, if it is determined in S2058 that the person is not closest to the operation direction of the excavator, the process proceeds to S2060.
- S2060 it is checked whether or not the height of the tip of the bucket 1c is equal to or less than the height of the obstacle set in S2054 and 2055.
- the contact risk is set to 4 (S2062), and the process proceeds to S2070.
- the contact risk is set to 3 (S2061), and the process proceeds to S2070.
- S2063 it is determined whether the operation of the hydraulic excavator is turning (right turning and left turning) or reverse based on the operation signal of the operating device or the time change of the detected angle ⁇ 4 of the angle detector 8d.
- the contact risk is set to 1 (S2064), and the process proceeds to S2070.
- the process proceeds to S2065.
- S2065 it is determined whether or not the obstacle is present at a position closest to the operation direction of the excavator as compared with other obstacles within the danger range. A specific method of the determination is the same as that described in S2058. If it is determined in S2065 that the obstacle is the closest to the direction of operation of the excavator, the contact risk is set to 4 (S2066), and the process proceeds to S2070. That is, in S2066, among obstacles whose type is in the danger range, the closest position to the front work device 1A or the hydraulic excavator is in the turning direction of the front work device 1A or the backward direction of the hydraulic excavator. The highest contact risk is set for an object (obstacle). On the other hand, if it is determined in S2065 that the object is not closest to the operation direction of the excavator, the process proceeds to S2067.
- S2067 it is checked whether the height of the tip of the bucket 1c is equal to or less than the height of the obstacle set in S2073. If the height of the bucket 1c is equal to or less than the height of S2073, the contact risk is set to 3 (S2069), and the process proceeds to S2070. On the other hand, in S2067, when the height of the bucket 1c is higher than the height of S2073, the contact risk is set to 2 (S2068), and the process proceeds to S2070.
- the danger level setting unit 2000 checks whether or not contact danger levels have been set for all obstacles within the danger range. If there is an obstacle for which the contact risk level has not yet been set in the danger range, the process returns to S2052, and the processes from S2052 onward are repeated. If it is determined in S2070 that the contact risk is set for all obstacles, the process is temporarily terminated. In addition, when the danger range is updated or an obstacle is newly detected, the above-described series of risk setting processing is executed again as appropriate. By this processing, the contact risk can be set for all obstacles existing in the danger range. At this time, when a person exists in the danger range when the excavator turns or reversely moves, the highest contact risk (5) can be set for the person.
- contact risk is based on the type of obstacle (person or object), position (within danger range / close to hydraulic excavator), and height (lower than the tip of bucket 1c).
- the degree of contact may be set for each obstacle based on at least one of them.
